WRC Nairobi 2007: wreck removal convention

The Nairobi International Convention on the Removal of Wrecks 2007, commonly the Wreck Removal Convention or WRC, is the first global treaty to give coastal States a clear legal basis to compel the removal of hazardous wrecks beyond their territorial sea, to channel the cost of that removal onto the registered owner under a strict-liability rule, and to back the resulting claim with compulsory insurance evidenced by a State-issued certificate. Adopted at the IMO Diplomatic Conference in Nairobi on 18 May 2007 and entered into force on 14 April 2015, the Convention closed a structural gap exposed by the Tricolor casualty in the English Channel in December 2002 and by repeated coastal-State frustration that the Exclusive Economic Zone, beyond 12 nautical miles, fell outside both CLC 1992 for oil-cargo pollution and Bunkers Convention 2001 for bunker-fuel pollution where the wreck itself, rather than its discharged cargo, was the hazard. WRC defines a “wreck” expansively to include sunken or stranded ships, equipment fallen at sea, and ships about to sink that are not under salvor effective control, and it permits each State Party to opt in to EEZ application under Article 3.2 or to opt out and confine the regime to its territorial waters. Liability under Article 10 mirrors the Bunkers 2001 architecture: strict, channelled to the registered owner, and limited under whichever LLMC regime binds the forum State, with no Convention-specific cap. The WRC Blue Card under Article 12 is mandatory for any ship of 300 GT or above visiting a port or anchorage of a State Party, and is issued in practice by the International Group P&I Clubs. The Convention now binds approximately 75 States including the United Kingdom, Germany, the Netherlands, Denmark, China, Singapore, Liberia, the Marshall Islands, and Panama, with notable abstentions including the United States, Greece, and India. Major casualties tested or shaped the regime including Costa Concordia (Giglio 2012), Modern Express (Bay of Biscay 2016), and the MV Wakashio wreck-removal phase off Mauritius (2020). WRC operates alongside the broader MARPOL family, with HNS 2010 addressing chemical and LNG cargo damages once it enters into force, and Annex I prevention and the SOPEP regulation governing the operational pollution regime.

Background: the pre-2007 wreck-removal gap

For most of the twentieth century the international maritime liability architecture concerned itself with pollution damage rather than with the wreck itself. The Torrey Canyon of 1967, the Amoco Cadiz of 1978, and the Erika of 1999 each produced legislative responses focused on the discharge of persistent oil from cargo tanks. The wreck that remained on the seabed, with its residual bunker, lubricants, and any cargo not recovered, sat in a regulatory shadow. Coastal States exercised undisputed sovereignty within the territorial sea, the 12-nautical-mile belt established under UNCLOS Article 3, and could direct removal of any hazard within that belt under domestic statute. Beyond 12 nautical miles, in the Exclusive Economic Zone that UNCLOS Part V extends to 200 nautical miles, the position was contested. The coastal State held sovereign rights for resource exploitation and limited jurisdiction for marine environmental protection under Article 56, but the right to compel the registered owner of a foreign-flagged wreck to fund its removal was not expressly granted. Several IMO Legal Committee studies during the 1990s concluded that this lacuna was the principal weakness of the pollution-liability edifice.

The practical consequence was that coastal-State authorities frequently financed wreck-removal operations from public funds and then attempted to recover the cost through tort or salvage claims in flag-State or owner-domicile courts, with mixed results. P&I Clubs settled most claims pragmatically under their wreck-removal cover, but in the absence of a binding international regime there was no compulsory insurance, no direct-action right, no minimum financial guarantee, and no common definition of when a wreck became a removable “hazard.” Owners with a single-ship company structure could and sometimes did walk away from a wreck whose value had fallen below removal cost. Coastal States with limited budgets, particularly small island developing States, faced wrecks they could not afford to remove and could not enforce against.

The IMO Legal Committee placed a Wreck Removal Convention on its work programme in 1996, in parallel with the Bunkers Convention work that ultimately produced Bunkers 2001. Drafts circulated through the late 1990s and early 2000s. The Diplomatic Conference convened in Nairobi from 14 to 18 May 2007 at the invitation of the Government of Kenya, a coastal State whose own coastline had repeatedly contended with abandoned wrecks. The Convention was adopted by consensus on 18 May 2007. Entry-into-force conditions required ratification by 10 States, met when Denmark deposited the tenth instrument on 14 April 2014; the Convention entered into force one year later, on 14 April 2015.

Tricolor 2002 and the political driver

No single casualty did more to crystallise political support for the Convention than the Tricolor, a Norwegian-flagged car carrier that sank in the Dover Strait on 14 December 2002 following a collision with the container ship Kariba in dense fog. The Tricolor came to rest in the traffic separation scheme at a depth of about 30 metres, with her superstructure protruding above the waterline and approximately 2,400 vehicles still aboard. Within ten days of the sinking she was struck twice by other vessels: the Nicola ran into the wreck on 16 December 2002 and the laden tanker Vicky ran into her on 2 January 2003, the latter releasing a small bunker spill into one of the busiest shipping lanes in the world. The wreck was finally removed in nine pieces by Smit Salvage through 2003 and into 2004 at a cost reported in the regional press as in excess of EUR 35 million.

Two features of the Tricolor casualty fed directly into the Convention text. The wreck lay outside the territorial sea of any single coastal State, in waters where Belgian, French, and United Kingdom EEZ jurisdiction overlapped or was contested for hazard-management purposes. The coordination of removal therefore depended on bilateral agreements struck under time pressure. The wreck, although not pollution-laden in the CLC sense, was a navigational hazard whose continued presence repeatedly endangered other shipping. The Tricolor file demonstrated that “wreck as hazard” required a regime distinct from “cargo as pollutant,” that the regime needed to operate in the EEZ, and that the registered owner had to bear the cost under compulsory insurance. Conference delegates referenced the casualty repeatedly during the Nairobi negotiations.

2007 adoption and 2015 entry into force

The Convention as adopted comprises 21 articles and an annex containing the certificate of insurance form. Article 1 sets out definitions, including the definition of “wreck” in Article 1.4, the definition of “hazard” in Article 1.5, the definition of “Convention area” in Article 1.1, and the definition of “registered owner” in Article 1.8. Articles 2 and 3 govern objectives and geographical application. Articles 5 to 9 govern reporting, locating, marking, and removal procedures. Article 10 channels strict liability to the registered owner. Article 11 sets out narrow exceptions. Article 12 imposes the compulsory-insurance and certificate regime. Articles 13 to 15 govern time-bar, jurisdiction and recognition. The remaining articles deal with relationship to other conventions, signature, ratification, denunciation, and amendment.

Entry-into-force required deposit of instruments of ratification, acceptance, approval, or accession by 10 States. The first deposit was Bulgaria in October 2008. Denmark deposited the tenth instrument on 14 April 2014, triggering the one-year clock in Article 18. The Convention entered into force on 14 April 2015. The IMO Secretariat acts as depositary; the Maritime Safety Committee monitors implementation; the Legal Committee reviews disputes and amendments.

Scope: definition of “wreck”

Article 1.4 defines a “wreck” as following upon a maritime casualty: any one of four states. The first is a sunken or stranded ship. The second is any part of a sunken or stranded ship, including any object that is or has been on board such a ship. The third is any object that is lost at sea from a ship, and that is stranded, sunken, or adrift at sea. The fourth, drafted to capture casualties before final loss, is a ship that is about, or may reasonably be expected, to sink or to strand, where effective measures to assist the ship or any property in danger are not already being taken. The fourth limb is critical because it preserves the distinction between wreck removal under WRC and salvage under the 1989 Salvage Convention and Lloyd’s Open Form. While salvors are engaged and salvage services are being effectively rendered, the casualty is not yet a wreck for WRC purposes and Article 11.1(c) excludes WRC liability for costs that fall under the Salvage Convention or LOF.

The phrase “object that has been on board” captures cargo, deck equipment, lashings, containers, tank tops, hatch covers, and any other ship-related material. The Tricolor cargo of 2,400 vehicles fell within the definition. Lost containers from a ULCS in heavy weather fall within the definition if they remain stranded, sunk, or adrift; this captures the hazard profile of cases such as MSC Zoe (North Sea 2019) and ONE Apus (Pacific 2020), although those casualties were primarily managed under domestic North Sea or Japanese frameworks.

A “maritime casualty” is defined in Article 1.3 as a collision of ships, stranding or other incident of navigation, or other occurrence on board a ship or external to it resulting in material damage or imminent threat of material damage to a ship or its cargo. The definition is purposely broad and includes weather damage, hull failure, fire, explosion, and contact with submerged obstructions.

EEZ extension under Article 3.2 (opt-in)

Article 3.1 establishes that the Convention applies to wrecks located in the Convention area, defined in Article 1.1 as the Exclusive Economic Zone of a State Party established in accordance with international law or, if a State Party has not established such a zone, an area beyond and adjacent to the territorial sea of that State, not extending more than 200 nautical miles from the baselines from which the breadth of its territorial sea is measured. The default geographical scope is therefore the EEZ.

Article 3.2 contains the central novel provision of the Convention: a State Party may, by notification to the IMO Secretary-General at the time of expressing consent to be bound or at any time thereafter, extend the application of the Convention to wrecks located within its territorial sea as well as in its EEZ. This is the opt-in provision for territorial-waters application. Most major flag and port States have opted in, including the United Kingdom, Germany, the Netherlands, Denmark, France, and Singapore. The opt-in is operationally significant because it means a single legal regime, a single liability rule, a single insurance certificate, and a single direct-action right govern the wreck whether it lies five nautical miles or fifty nautical miles from the coast.

The phrase “without prejudice to” in Article 4 preserves UNCLOS Article 17 innocent passage, UNCLOS Articles 56 and 58 EEZ rights and duties, and the general allocation of jurisdiction at sea. WRC does not enlarge coastal-State jurisdiction in the abstract; it provides a specific, narrow, hazard-focused legal basis tied to compulsory insurance and direct-action recovery.

Strict liability of the registered owner

Article 10.1 provides that the registered owner shall be liable for the costs of locating, marking, and removing the wreck unless one of the narrow exceptions in Article 11 applies. Liability is strict, meaning fault need not be proved by the affected State; the only causation question is whether the cost was incurred in respect of a wreck within the meaning of Article 1.4. Liability is channelled to the registered owner: claims by the affected State for these costs may be made only against the registered owner, mirroring the channelling architecture of CLC 1992 Article III.4 and Bunkers 2001 Article 3.

The “registered owner” is defined in Article 1.8 as the person or persons registered as the owner of the ship or, in the absence of registration, the person or persons owning the ship at the time of the maritime casualty. For a ship registered as bareboat-charter-in to a flag of registration, the registered owner is the bareboat charterer. The narrow scope of channelling, compared with the broader Bunkers 2001 Article 1.3 list that includes operator and manager, was a deliberate negotiating outcome: WRC delegates concluded that the EEZ extension and the compulsory-insurance certificate provided sufficient claim-recovery security without requiring joint and several liability across a wider party set.

Article 11 sets out three narrow exceptions in language modelled on CLC and Bunkers: an act of war, hostilities, civil war, insurrection, or natural phenomenon of an exceptional, inevitable, and irresistible character; an act or omission done with intent to cause damage by a third party; or wholly or partly the negligence or other wrongful act of any government or other authority responsible for the maintenance of lights or other navigational aids in the exercise of that function. Article 11.1(c) further excludes costs already recovered under the 1989 Salvage Convention or under CLC 1992 or under Bunkers 2001 for the same incident, preventing double recovery.

Limitation of liability via LLMC (no separate WRC cap)

Unlike CLC 1992 and the HNS Convention 2010, WRC does not contain a Convention-specific monetary cap on liability. Article 10.2 expressly provides that nothing in the Convention shall affect the right of the registered owner to limit liability under any applicable national or international regime, such as the Convention on Limitation of Liability for Maritime Claims, 1976, as amended. The forum State applies the LLMC regime that binds it. For a State that has ratified the LLMC 1996 Protocol as further amended by the 2012 amendments that entered into force on 8 June 2015, the wreck-removal claim is limited under LLMC Article 6 by reference to the gross tonnage of the vessel responsible. For property claims under LLMC 1996 as amended, the threshold floor is 1,510,000 SDR for ships up to 2,000 GT, scaled progressively above that figure on the LLMC 1996 sliding scale.

A critical operational point is that in many LLMC States the wreck-removal claim is not subject to limitation, because LLMC Article 18 permits Contracting States to reserve the right to exclude wreck-removal and cargo-removal claims from the limitation regime. The United Kingdom, Germany, France, Norway, Denmark, the Netherlands, and many other major maritime States have made the Article 18 reservation. Within those jurisdictions the registered owner faces strict, channelled, and unlimited liability for wreck-removal costs. The compulsory-insurance regime under Article 12 then becomes the practical financial guarantee.

For LLMC States that have not made the Article 18 reservation, the limit applies and the LLMC tonnage-scaling formula determines the cap. The full formula appears in the Formula, assumptions, and limits section below.

WRC Blue Card under Article 12

Article 12.1 requires the registered owner of a ship of 300 GT or above flying the flag of a State Party to maintain insurance or other financial security, such as a guarantee of a bank or similar institution, to cover liability under the Convention in an amount equal to the limits of liability under the applicable national or international limitation regime, in all cases not exceeding an amount calculated in accordance with LLMC 1976 Article 6 as amended. A certificate attesting to such insurance is required to be on board the ship at all times.

The certificate is issued by the appropriate authority of the flag State, in practice on the basis of a Blue Card issued by an International Group P&I Club confirming that wreck-removal cover is in force. The form of the certificate is contained in the annex to the Convention. The certificate must contain the name of the ship, distinctive number or letters, IMO ship identification number, port of registry, name and principal place of business of the registered owner, the type of security, and the period of validity. The certificate is required for ships of any flag, party or non-party, when entering or leaving a port or arriving at or leaving an offshore facility in the territorial sea or internal waters of a State Party.

The Blue Card, although a P&I document and not the Convention certificate itself, is in practical terms the master document. The International Group of P&I Clubs operates a centralised Blue Card system that produces certificates for CLC, Bunkers 2001, WRC, and HNS 2010 once it is in force. Issuance is contingent on the entered owner remaining in good standing with the Club and on the wreck-removal cover not being terminated for non-payment of calls.

Compulsory insurance: ships ≥300 GT visiting WRC State Party

The 300 GT threshold in Article 12 is identical to the threshold for SOLAS ISM Code application and considerably lower than the 1,000 GT threshold under Bunkers 2001 Article 7. The lower threshold reflects the wreck-hazard reality that even small coasters and fishing vessels can become a navigational or environmental hazard when they sink in shallow approaches.

The certificate must be carried on board, must be in the official language of the issuing State (with English, French, or Spanish translation if not in one of those languages), and must be produced on demand. Port-State control inspections under the Paris and Tokyo MOUs include WRC certificate verification within their checklists; absence of a valid certificate is grounds for detention.

For non-party flag ships visiting a State Party port, the certificate must be issued by the authorities of that flag, of any State Party, or recognised by the State Party in question. In practice the Republic of the Marshall Islands, Liberia, Panama, Singapore, the Bahamas, Malta, and Cyprus issue WRC certificates against International Group Blue Cards on the standard 12-month renewal cycle aligned with P&I policy renewal at 20 February.

Opt-out for territorial-waters-only application

Article 4.4, read together with Article 3.2, embeds an asymmetric flexibility. A State Party that does not wish to apply the Convention to wrecks within its territorial sea may simply refrain from making the Article 3.2 notification. The default scope remains the EEZ. Some early States Parties used this approach because their domestic wreck-removal statutes were already comprehensive and they wished to preserve the existing domestic regime within 12 nautical miles while gaining the EEZ-extension benefit beyond 12 nautical miles. The notification is reversible in either direction: a State may notify extension and later withdraw the notification, or vice versa.

The practical drift since 2015 has been toward universal opt-in. The United Kingdom opted in on ratification in 2014. Germany opted in. The Netherlands opted in. France, Belgium, Denmark, Norway, Singapore, and most flag States with significant tonnage opted in at ratification. The current position is that the territorial-waters-plus-EEZ application is the operational norm and the EEZ-only configuration is exceptional. Calculators and contingency-planning teams should treat WRC as covering the full Convention area within 200 nautical miles for any flag that has ratified, subject to confirming the specific State’s notification position.

Ratification status: ~75 States (UK, Germany, NL, China yes; US, Greece, India not yet)

As of early 2026 approximately 75 States are bound, representing well over 70 percent of world tonnage by the IMO depositary count. Major flag and port States that are bound include the United Kingdom, Germany, the Netherlands, Denmark, Norway, Sweden, Finland, France, Belgium, Italy, Spain, Portugal, China, Singapore, Malaysia, Japan (acceded 2014), Republic of Korea (acceded 2018), Liberia, the Marshall Islands, Panama, Antigua and Barbuda, the Bahamas, Malta, Cyprus, Bulgaria, Romania, Croatia, Kenya, South Africa, Australia, New Zealand, and Canada.

Notable abstentions remain. The United States has not ratified the Convention. The US position is governed by the Wreck Act 1899 (33 USC s 401 ff) and by the Coast Guard’s broader marine-environmental authority under OPA 90 and the Federal Water Pollution Control Act. The federal regime is considered comprehensive within US navigable waters and EEZ, and US wreck-removal cost claims are funded in the first instance by the Oil Spill Liability Trust Fund for petroleum-related cases. Greece, the largest flag State by deadweight, has not ratified the Convention; Greek owners visiting WRC State Party ports must nonetheless obtain a WRC certificate either through their flag-of-registration State (where applicable) or through any other State Party that will issue against an acceptable Blue Card. India has not ratified the Convention. Several Mediterranean and African coastal States are at various stages of internal ratification process.

The asymmetry between port-State coverage and flag-State coverage is the principal operational reality. A non-party flag ship cannot escape WRC simply because her flag has not ratified: the moment she enters a State Party port, anchorage, or offshore facility, Article 12 requires her to carry a certificate.

Relationship to CLC 1992 (cross-link)

CLC 1992 imposes strict, channelled liability on the registered owner of a laden oil tanker for pollution damage from the discharge of persistent oil cargo. WRC imposes strict, channelled liability on the registered owner of any ship for wreck-removal costs. The two regimes overlap in fact when a laden oil tanker grounds, ruptures, and sinks: CLC 1992 funds the cleanup of discharged cargo and shoreline damage; WRC funds the removal of the hull, the residual cargo, and the bunker tanks. Article 11.1(c) of WRC excludes from WRC any cost that has been or could be recovered under CLC for the same incident, preventing double recovery.

The IOPC Fund 1992, layered above CLC, does not pay wreck-removal costs unless they are integral to pollution-damage prevention measures within the meaning of CLC Article I.6. The Fund’s standard practice, refined through the Erika and Prestige claim files, is to admit limited “preventive measures” wreck stabilisation costs but to exclude general wreck-removal costs that fall outside the pollution-damage definition. WRC fills this gap precisely.

Relationship to Bunkers Convention 2001 (cross-link)

Bunkers 2001 imposes strict, channelled, joint-and-several liability on the registered owner, bareboat charterer, manager, and operator of any seagoing ship for pollution damage caused by bunker oil. WRC imposes liability for wreck-removal costs. Where a non-tanker grounds, breaks up, and discharges bunker oil, both regimes apply: Bunkers 2001 funds the bunker-spill response and shoreline cleanup; WRC funds the removal of the hull and any residual bunker tanks not pumped out during the response phase. The Wakashio casualty of 2020 off Mauritius is the canonical example of the two regimes operating in parallel.

A key operational distinction is the channelling architecture. Bunkers 2001 reaches a wider party set (Article 1.3); WRC channels narrowly to the registered owner only (Article 1.8). Claim-handling teams therefore confront a single defendant under WRC and a four-defendant set under Bunkers, even though the underlying incident is a single casualty. The P&I Club is in practice the same insurer in most cases, and the Blue Card system aligns the two certificates on a common renewal cycle.

Relationship to HNS Convention 2010 (cross-link)

The HNS Convention 2010, formally the International Convention on Liability and Compensation for Damage in Connection with the Carriage of Hazardous and Noxious Substances by Sea, has not yet entered into force; the entry-into-force conditions of the 2010 Protocol require ratification by 12 States including 4 with at least 2 million units of gross tonnage and an HNS-receiving threshold of 40 million tonnes of contributing cargo. Once in force, HNS will impose strict, channelled, capped liability on the registered owner for damage caused by hazardous and noxious substances, with a layered HNS Fund above the owner’s first tier.

When HNS does enter into force, the relationship with WRC will be analogous to the CLC/WRC relationship. HNS will fund pollution and damage from chemical, LNG, LPG, and packaged dangerous goods cargo discharges. WRC will continue to fund the removal of the hull and any residual cargo not recovered under HNS. Article 11.1(c) of WRC, drafted to exclude double recovery with “any other applicable convention,” is constructed to accommodate HNS at entry into force without further amendment.

Per-state competent authority: MCA, BSH, WSV

Each State Party designates one or more competent authorities under Article 9.1 with responsibility for hazard determination, removal direction, and certificate enforcement. The list of competent authorities is published in the IMO Depositary status document. Three illustrative examples follow.

United Kingdom: MCA and the GLAs

The Maritime and Coastguard Agency is the competent authority for the United Kingdom, which ratified the Convention by deposit of 8 February 2011 with effect from 14 April 2015. The MCA acts through the Secretary of State’s Representative for Maritime Salvage and Intervention (SOSREP). The General Lighthouse Authorities (Trinity House for England, Wales and the Channel Islands; Northern Lighthouse Board for Scotland and the Isle of Man; Commissioners of Irish Lights for Ireland) handle marking of wrecks under their navigational-aid mandate. Domestic implementing legislation is the Wreck Removal Convention Act 2011 and the Merchant Shipping (Convention on Limitation of Liability for Maritime Claims) (Amendment) Order 2014.

Germany: BSH and WSV

The Bundesamt fuer Seeschifffahrt und Hydrographie (BSH) is the federal hydrographic authority responsible for wreck identification, charting, and notice. The Wasserstrassen- und Schifffahrtsverwaltung (WSV) under the Federal Ministry of Transport is the operational competent authority for hazard determination and removal direction in the German EEZ in the North Sea and Baltic. The Havariekommando (Central Command for Maritime Emergencies) at Cuxhaven is the unified incident command in major casualties. Implementing legislation sits within the Seeaufgabengesetz and the Wrackbeseitigungsuebereinkommen-Ausfuehrungsgesetz of 2013.

Other State Parties

The Netherlands designates Rijkswaterstaat acting under the Ministry of Infrastructure and Water Management. France designates the Premar (Maritime Prefect) for each of the three maritime facades (Manche-Mer du Nord, Atlantique, Mediterranee). Denmark designates the Soefartsstyrelsen (Danish Maritime Authority). Norway designates the Kystverket (Norwegian Coastal Administration). Singapore designates the Maritime and Port Authority of Singapore (MPA). The IMO Depositary list is the authoritative reference and is updated on each notification.

Historical incidents: Costa Concordia 2012, Modern Express 2016, Wakashio 2020

Costa Concordia (Giglio 2012)

The Italian-flagged cruise ship Costa Concordia struck rocks off the Tuscan island of Giglio on 13 January 2012 with 4,229 persons on board, capsizing and partially sinking with the loss of 32 lives. The wreck lay in territorial waters off Giglio, on a sloping seabed between 8 and 70 metres of depth. Italy had not yet ratified the Convention at the time of the casualty, and the wreck-removal operation was managed under domestic Italian framework with the Comando Operativo del Vertice as competent authority. Nonetheless the file directly informed the Convention community on three points: the parbuckling technique developed by Titan Salvage and Micoperi to right the wreck in September 2013 became the reference precedent for large-cruise-ship wreck removal; the total wreck-removal cost approached EUR 1.5 billion, larger than the LLMC limit for the vessel and demonstrating why the Article 18 unlimited-wreck-removal reservation matters in practice; and the multi-year timeline (2012 to 2014 wreck removal, 2015 dismantling at Genoa) shaped expectations for future cruise wrecks. The casualty demonstrated that the LLMC sliding-scale property limit, even at the 2012-amendment uplift, is a small fraction of cruise-ship wreck-removal cost.

Modern Express (Bay of Biscay 2016)

The Panama-flagged car carrier Modern Express, loaded with timber and excavators, listed heavily in the Bay of Biscay on 26 January 2016 during a transit from Gabon to Le Havre. The crew of 22 was airlifted off by Spanish and French rescue helicopters and the abandoned vessel drifted northeast toward the French Atlantic coast. The French Premar Atlantique declared the vessel a hazard within the meaning of Article 6 of WRC and coordinated a Smit Salvage tow with French Navy assistance. After three failed attempts the salvage tug Centaurus secured a tow line on 1 February 2016 and brought the vessel to anchor off Bilbao. WRC was the operative regime: French and Spanish authorities coordinated under Article 9 hazard-determination provisions; the registered owner provided WRC Article 12 evidence of insurance; the operation cost was estimated in the regional press at approximately EUR 10 million. The casualty is the canonical clean test of the post-EIF Convention machinery.

MV Wakashio (Mauritius 2020)

The Japanese-owned, Panama-flagged Capesize bulker MV Wakashio grounded on Pointe d’Esny reef off Mauritius on 25 July 2020 while in ballast on passage from Singapore to Brazil. On 6 August she began discharging VLSFO from a fractured fuel tank; approximately 1,000 tonnes were released before a salvage team transferred the remaining bunker. The wreck broke in two on 15 August 2020. Mauritius is a Party to the Bunkers Convention and to WRC. The bunker spill response was funded under Bunkers 2001 including ITOPF technical advice. The wreck-removal phase was funded under WRC: the bow section was towed to deep water and scuttled in late August 2020; the stern section was removed in fragmented operations through 2021. Total claim quantum exceeded the LLMC 1996 limit applicable to the vessel; Mauritius, having made the Article 18 reservation, sought unlimited wreck-removal recovery from the registered owner.

Other notable cases

The Comoros Ali Express 2018 grounding at Anjouan was managed under the WRC framework with International Group P&I support. The Solomon Trader bauxite carrier grounding at Rennell Island in February 2019 was managed under the regional Pacific Islands framework with WRC certificate cover. The Bow Jubail chemical tanker grounding in Rotterdam in 2018 produced cargo and bunker contamination managed under Bunkers and the relevant chemical-cargo regime, with wreck stability stabilised under Dutch Rijkswaterstaat WRC authority.

Relationship to OPRC 1990 / OPRC-HNS Protocol

The International Convention on Oil Pollution Preparedness, Response and Cooperation 1990 and its 2000 HNS Protocol establish the operational response regime for oil and HNS spills: national contingency plans, regional cooperation, mutual assistance, equipment stockpiles, and exercise programmes. OPRC and OPRC-HNS do not impose civil liability and do not address wreck removal; they govern the speed, structure, and resourcing of the spill-response operation while it is in progress.

WRC sits downstream of OPRC. Once the OPRC operational response is complete, the wreck and any residual cargo or bunker remain. WRC governs the cost of removing them. The two regimes operate sequentially in time and complementarily in function. The Tier 2 and Tier 3 spill-response capability of OPRC is reinforced by SOPEP at the ship level and by the regional MOU framework; WRC reinforces the recovery side once the incident is contained.

Commercial implications: P&I Blue Card, Norwegian Cruise Line, cruise contingency

P&I Club Blue Card issuance

The International Group of P&I Clubs, comprising the 12 mutual associations that between them cover approximately 90 percent of world ocean tonnage, operates the Blue Card system for CLC 1992, Bunkers 2001, and WRC 2007. WRC Blue Cards are issued automatically on entry of a vessel and are renewed annually with the 20 February policy renewal common to all International Group Clubs. The Blue Card confirms that the Club’s standard wreck-removal cover, subject to the Pooling Agreement and to the Group reinsurance programme, is in force. Termination of cover by the Club, whether for non-payment of calls or for cessation of risk, triggers cancellation of the Blue Card and notice to the issuing flag-State authority.

Cover sub-limits and reinsurance

International Group reinsurance places a USD 1 billion limit per ship per incident on combined pollution and wreck-removal cover. Above the Group reinsurance, owners with very large vessels (Capesize bulkers, ULCS, VLCC, very-large cruise ships) may purchase additional layered cover commercially. The Group’s wreck-removal historical loss ratio runs higher than its pollution loss ratio because wreck-removal incidents are typically catastrophic single events, while pollution incidents distribute across a wider claim spectrum. Wakashio and Costa Concordia each tested the reinsurance tower; both were settled within capacity.

Cruise-industry contingency funding

Large cruise ship wrecks present the most extreme wreck-removal cost profile. Costa Concordia’s EUR 1.5 billion total cost, of which the wreck-removal phase was approximately EUR 800 million, is the reference point. Newer Oasis-class and Icon-class cruise ships of 230,000 GT and above present a wreck-removal exposure that no individual P&I Club could fund without the Pooling Agreement and the Group reinsurance tower. The cruise lines have responded with enhanced contingency planning, sister-ship lift capacity, and pre-arranged salvage retainer agreements with Smit, Boskalis, Resolve Marine, and Titan Salvage.

The Norwegian Cruise Line “Polar Express” planning case (a 2022 contingency-planning exercise widely circulated within the cruise industry, not a real casualty) modelled the wreck-removal cost of a 5,000-passenger cruise ship grounding in Antarctic waters and concluded that the operation would exceed USD 2 billion and require multi-flag cooperation. The exercise reinforced the case for Article 18 reservations across all major cruise-destination States and for sustained Group reinsurance capacity.

Comparison with 1989 Salvage Convention and SCOPIC clause

The International Convention on Salvage 1989 governs the commercial salvage relationship between salvor and shipowner: when salvage services are rendered with a useful result, the salvor is entitled to a reward; the reward is enhanced where the salvor prevents or minimises damage to the environment under Article 14. Salvage is consensual, time-limited, and reward-based, and it operates while the casualty remains a ship under salvor effective control.

The SCOPIC clause (“Special Compensation P&I Club” clause), incorporated into Lloyd’s Open Form salvage agreements since 1999, provides a tariff-based compensation mechanism for the salvor for environmental services that may not produce a useful result. SCOPIC bridges the gap between Article 14 enhanced salvage and pure liability for environmental damage. It is the operative agreement during the active salvage phase of most modern casualties, including Wakashio and Modern Express.

The relationship to WRC is sequential. While SCOPIC is engaged and salvors are effectively rendering services, the casualty is not yet a wreck under WRC Article 1.4 and Article 11.1(c) excludes WRC liability for costs that fall under salvage. Once SCOPIC services terminate, whether by successful redelivery to safe haven or by abandonment to a wreck state, WRC takes over for any further hazard-management cost. The transition point is a matter of fact: whether effective salvage services are still being rendered. Tribunal practice under LOF and SCOPIC has produced a body of decisions on the precise transition that flow through into WRC claim files.

The 1989 Salvage Convention has been the subject of a long-running review at the IMO Legal Committee, with a 2019 Working Group considering modernisation of Article 14 and the SCOPIC tariff. WRC sits stable within the broader regime as the wreck-removal complement to salvage’s casualty-control function.

Formula, assumptions, and limits

Formula

The applicable wreck-removal liability ceiling, where the forum State has not made the LLMC Article 18 reservation, is the LLMC 1996 property-claim limit as amended in 2012. For a vessel of gross tonnage GT, the limit in Special Drawing Rights is:

L_{\text{LLMC,WRC}}(GT) = \begin{cases} 1{,}510{,}000 \text{ SDR} & GT \leq 2{,}000 \\ 1{,}510{,}000 + 604(GT - 2{,}000) \text{ SDR} & 2{,}000 < GT \leq 30{,}000 \\ 1{,}510{,}000 + 604(28{,}000) + 453(GT - 30{,}000) \text{ SDR} & 30{,}000 < GT \leq 70{,}000 \\ 1{,}510{,}000 + 604(28{,}000) + 453(40{,}000) + 302(GT - 70{,}000) \text{ SDR} & GT > 70{,}000 \end{cases}

The SDR converts to local currency using the IMF daily SDR rate at the date of constitution of the limitation fund.

Derivation

The LLMC 1996 Protocol Article 6 establishes a piecewise-linear property-claim limit scaling with GT. The 2012 IMO amendments, adopted by Resolution LEG.5(99) and entered into force on 8 June 2015, uplifted the 1996 figures by approximately 51 percent to reflect inflation since 1996. The piecewise-linear scaling reflects the actuarial finding that wreck-removal cost scales sub-linearly with vessel size for small craft and approximately linearly with displacement for large craft, with diminishing marginal cost above 30,000 GT and 70,000 GT thresholds. WRC Article 10.2 incorporates this LLMC scaling by reference; there is no Convention-specific cap.

Assumptions

The formula assumes the forum State applies LLMC 1996 as amended by 2012 and has not made the Article 18 reservation. For States that have made the reservation, the limit does not apply and liability is unlimited. The formula assumes a single registered owner constituting a single limitation fund; multi-vessel collisions producing multiple wrecks may produce multiple limitation funds. The SDR exchange rate is fixed at the date of fund constitution; subsequent currency movements do not adjust the fund.

Worked example

A Capesize bulker of 90,000 GT grounds and breaks up. The forum State applies LLMC 1996/2012 and has not made the Article 18 reservation. The limit is:

L = 1{,}510{,}000 + 604 \cdot 28{,}000 + 453 \cdot 40{,}000 + 302 \cdot 20{,}000 = 42{,}542{,}000 \text{ SDR}

At an SDR rate of approximately 1.32 USD per SDR (illustrative), the limit converts to approximately USD 56.2 million. Wreck-removal costs in excess of this figure are not recoverable from the registered owner under the LLMC limitation regime, although they remain recoverable in States that made the Article 18 reservation.

Edge cases and limits

Vessels below 300 GT are not subject to the WRC compulsory-insurance regime under Article 12 but remain subject to WRC liability under Article 10. The compulsory-insurance ceiling for Article 12 purposes is calculated under LLMC 1976 Article 6 even where the State applies LLMC 1996/2012 to the substantive claim, reflecting the Convention’s pre-2012 drafting baseline. Where the State has made the Article 18 reservation, the certificate ceiling is still the LLMC 1976 figure but the substantive claim is uncapped. Multi-incident scenarios where the same vessel suffers two casualties in close succession give rise to two separate WRC claims, each with its own limitation fund. Joint-venture, partnership, and trust ownership structures are pierced for Article 1.8 registered-owner identification by reference to the actual flag registration.

Regulatory basis

WRC 2007 Articles 1, 3.1, 3.2, 4, 6, 9, 10, 11, 12, and the certificate annex; LLMC 1976 Article 6 and Article 18 reservation; LLMC 1996 Protocol Article 3; 2012 LLMC Amendments via Resolution LEG.5(99); IG P&I Club Pooling Agreement and Blue Card system; UK Wreck Removal Convention Act 2011; German Wrackbeseitigungsuebereinkommen-Ausfuehrungsgesetz 2013.

Common errors

Confusing the 300 GT compulsory-insurance threshold (Article 12) with the 1,000 GT Bunkers Convention threshold (Bunkers Article 7). Confusing the WRC channelling to the registered owner only (Article 1.8) with the broader Bunkers Article 1.3 channelling that includes operator and manager. Assuming the LLMC limit always applies to wreck removal: it does not, in any State that has made the Article 18 reservation. Assuming WRC certificate is needed only at the destination port: it must be on board at all times within the EEZ of any State Party. Confusing salvage (commercial, consensual, reward-based, 1989 Convention and SCOPIC) with wreck removal (statutory, compulsory, cost-recovery-based, WRC 2007).
