The Ship Inspection Report Programme (SIRE) is the tanker vetting framework administered by the Oil Companies International Marine Forum (OCIMF). It is the principal mechanism by which the major oil and chemical charterers, traders, and terminals assess the suitability of a tanker for a specific commercial voyage. SIRE is technically a database and inspection-report exchange, not a regulatory regime: it carries no force of law. The commercial pressure it exerts, however, has made compliance with the underlying questionnaires effectively mandatory for any vessel seeking employment in the mainstream international tanker trades.
The programme was launched in 1993 in response to the Exxon Valdez casualty of March 1989 and the subsequent recognition that tankers calling at oil major terminals were assessed inconsistently across charterers, with no centralised record of findings. The current regime, SIRE 2.0, entered phased operation in 2022 and reached full operational status in 2024 with mandatory use of the seventh edition Vessel Inspection Questionnaire (VIQ7) and the tablet-based inspection platform. This article covers how the programme works in practice for masters, chief engineers, technical operators, and vetting staff.
Historical context: from Exxon Valdez to SIRE 2.0
The Exxon Valdez ran aground on Bligh Reef, Prince William Sound, Alaska, on 24 March 1989, spilling an estimated 37,000 tonnes of crude oil. The casualty accelerated regulatory and industry responses across the shipping world. At the IMO, it contributed to the drive toward mandatory ISM Code certification, which entered force under SOLAS Chapter IX in July 1998 for tankers. Within OCIMF, it crystallised discussions that had begun in the early 1980s about creating a shared inspection record database.
SIRE was formally launched in 1993, with oil major members contributing inspection reports into a central database accessible to all Submitting Members. The early questionnaire, VIQ1, was a relatively simple checklist. Successive editions refined the question set, expanded the topic chapters, and introduced more rigorous reporting formats. VIQ6, the final edition under the SIRE 1.0 framework, was in use from 2011 until the transition to SIRE 2.0 and VIQ7 from 2022 onward.
The Deepwater Horizon casualty of April 2010, the subsequent regulatory attention on offshore operations, and a series of academic studies into tanker safety culture through the 2010s collectively reinforced the view within OCIMF that a checklist-only inspection model was insufficient. Inspectors completing VIQ6 checklists could confirm that a fire hose was present and in date without observing whether the crew knew how to deploy it under pressure. This was the core problem SIRE 2.0 was designed to address.
SIRE 2.0: the three-lens framework
SIRE 2.0 rests on the principle that every observable condition on board has three contributing dimensions: the physical hardware, the management processes that govern it, and the human behaviour of the crew interacting with it. Every VIQ7 question is assessed against all three lenses, and observations may be raised under any combination.
A deficiency identified against the hardware lens alone (for example, a corroded pipe fitting) is a materially different finding from the same fitting assessed against the human element lens (crew unaware the fitting is defective, no reporting culture). The distinction matters for the root cause analysis, the corrective action, and the vetting decision. A hardware defect can be repaired; a behavioural defect requires a change in management culture.
This triple-lens assessment is the single most significant structural departure from SIRE 1.0. It requires inspectors with skills in crew observation and interview, not just equipment inspection. It requires operators to maintain management systems with auditable documentation, not just physical maintenance records. And it requires the OCIMF inspector training and accreditation system to include behavioural assessment alongside technical surveying.
Vessel Particulars Questionnaire
The Vessel Particulars Questionnaire (VPQ) is the standardised data record that the tanker operator maintains in the OCIMF database. It contains the vessel’s IMO number, principal particulars (length, beam, deadweight, gross tonnage, year of build), classification society, flag state, and all major statutory certificates with expiry dates: SOLAS certificates including the Safety Construction Certificate, the Safety Equipment Certificate, and the Safety Radio Certificate; MARPOL certificates including the International Oil Pollution Prevention Certificate, the International Sewage Pollution Prevention Certificate, and the Garbage Management Plan; the Document of Compliance and Safety Management Certificate under the ISM Code; the International Ship Security Certificate under the ISPS Code; and the Maritime Labour Certificate under MLC 2006.
Beyond certificates, the VPQ records cargo system specifications: the number and capacity of cargo tanks, loading and discharge rates, heating coil specifications, inert gas system type, cargo pump details, the crude oil washing system where fitted, and vapour emission control system (VECS) information where fitted. The VOC from crude tanker loading calculator and the VECS connection calculator apply to several of these systems. The VPQ also records mooring equipment data keyed to OCIMF Mooring Equipment Guidelines (MEG4) compliance: winch brake capacities, mooring line breaking loads and dates, fairlead and bitt ratings, and the ship’s mooring plan. Mooring forces and station keeping is covered in the linked wiki article.
The VPQ is maintained by the operator and updated whenever there is a change: a class survey that alters the vessel’s structural condition notation, an amendment to the crewing arrangement, a certificate renewal, or an equipment change. Discrepancies between the VPQ and the actual vessel found during an inspection are themselves observations under VIQ7. A vessel with an outdated VPQ creates an immediate negative signal even before any technical question is assessed.
Charterer vetting departments use the VPQ for pre-screening: they filter the OCIMF database by criteria such as age, deadweight, cargo tank coating, inert gas type, and vapour lock capacity before deciding which vessels to nominate for inspection or to accept for a cargo. The VPQ is therefore commercially active data, not a passive record.
Vessel Inspection Questionnaire: structure and scope of VIQ7
VIQ7 is structured into fourteen chapters covering every operational aspect of a tanker. The chapters address:
- Certification and documentation
- Crew management, hours of rest, and STCW competency
- Navigation, bridge resource management (BRM), electronic chart systems, and communications
- Safety management, emergency procedures, drills, and fire and safety equipment
- Pollution prevention under MARPOL Annexes I, II, IV, V, and VI
- Structural condition, hull maintenance, and void space access
- Cargo and ballast systems, including tank gauging, ullaging, and stripping
- Mooring equipment and operations per MEG4
- Engine room and steering compartment: main engines, auxiliary machinery, fuel oil systems, lubricating oil systems, bilge and oily water systems
- General appearance, housekeeping, and maintenance culture
- Ice operations (applied only when the vessel trades in ice-class regimes)
- LNG and LPG operations (applied to gas carriers)
- Chemical tanker operations (applied to product and chemical tankers)
- Additional trade-specific sections
Each question within the fourteen chapters is drawn from three pools: Core, Rotational, and Conditional.
Core questions are asked at every inspection without exception. They cover the highest-consequence items: statutory certificates in date, safety management system compliance, critical alarm and safety system functionality, key crew competencies, and pollution-prevention equipment.
Rotational questions are drawn from a defined pool such that consecutive inspections of the same vessel do not necessarily ask the same set. The pool is large enough that the rotational questions covering any given vessel change across inspections. This design is deliberate: it discourages operators from preparing crew specifically for a known question set and instead requires consistent maintenance of standards across all areas. Over two or three consecutive inspections, most rotational questions will have been asked.
Conditional questions trigger when specific conditions are met: vessel type (gas carrier, chemical tanker), current operation (loading, STS transfer, bunkering), specific voyage characteristics (ice route, high-sulphur area operation), or earlier answers (a positive answer to one question generates follow-on questions probing the detail).
The VIQ7 Question Library is a companion document, not identical to the VIQ itself, that provides inspection guidance for each question: what the inspector should look for, which regulations and industry guidelines are referenced, what good practice looks like, and what constitutes a deficiency. The SIRE 2.0 Inspection Guidelines document sets out the procedural conduct of the inspection, inspector behaviour, confidentiality requirements, and reporting timelines.
SIRE 2.0 inspector categories and accreditation
SIRE 2.0 introduced a formal two-tier inspector structure.
Augmented Inspectors hold the higher qualification. They are authorised to conduct inspections during active cargo operations: loading, discharging, ship-to-ship (STS) transfer, tank cleaning, and bunkering. Augmented status requires the candidate to demonstrate prior experience as a tanker officer or master, pass the OCIMF written examination, complete a practical and simulator assessment component covering live cargo observation and human element behavioural assessment, and maintain continuing professional development (CPD) requirements. The Augmented pool is smaller than the Independent pool; Augmented inspectors are in higher demand for time-sensitive operations.
Independent Inspectors conduct inspections outside cargo operations: typically at anchor, in port between operations, or at a berth where no cargo movement is under way. Independent accreditation requires the written examination and CPD but not the live cargo practical assessment. Most new entrants to the inspector pool enter at Independent level and progress to Augmented after additional experience.
Both categories are accredited through OCIMF’s inspector programme. OCIMF does not employ inspectors directly; they are independent contractors engaging with Submitting Members who commission inspections. A single inspector may work across several oil major accounts over the course of a year. The commissioning Submitting Member bears the cost of the inspection; the vessel owner does not pay the inspector fee.
Inspector performance is monitored through OCIMF’s quality assurance programme. Inspectors who generate observation rates materially above or below the population norm for equivalent vessel types, or who receive complaints from operators or Submitting Members, are subject to review. Inspectors failing CPD requirements lose accreditation. OCIMF publishes no disaggregated inspector performance data to the market; the quality programme is internal.
The tablet-based inspection application is supplied by OCIMF to accredited inspectors. All findings, including photographs, are entered directly into the tablet during the inspection. On completion, the report is uploaded to the SIRE database through the application, removing the previous workflow of Word-document drafting, PDF conversion, and email submission that characterised the SIRE 1.0 process. Report publication latency dropped from several days under SIRE 1.0 to typically 24 to 48 hours under SIRE 2.0.
The human element: observed behaviour in SIRE 2.0
The behavioural assessment component of SIRE 2.0 is the most operationally significant change from the perspective of crew and operators. Under SIRE 1.0, an inspector could verify compliance with a procedure by checking that the written procedure existed and that the relevant crew member could describe it. Under SIRE 2.0, the inspector also observes whether the crew member actually applies it correctly in practice.
The human element questions cluster around several operational areas:
Bridge Resource Management (BRM): how the officer of the watch uses the navigation team, challenges orders, maintains situational awareness, and uses the electronic chart display and information system (ECDIS) under the SOLAS Chapter V and STCW requirements.
Engine room watchkeeping: engineer watch routines, alarm response times, log entry quality, and engineer familiarity with the condition of running machinery.
Cargo operations: officer competence in ullaging, trim and stability calculation (relevant to the tanker washings oil record book calculator and the VOC management plan calculator), independent verification of valve positions before transfer, and communication with the terminal or STS partner.
Mooring operations: crew familiarity with the MEG4 mooring plan for the vessel, correct use of winch brakes, maintenance of mooring lines, and fatigue management of deck crews during extended mooring watch.
Safety culture indicators: crew willingness to stop an operation and report a near-miss, officer ability to describe the ISM Code non-conformity reporting process, and evidence that safety meetings are substantive rather than pro-forma.
The inspector is not testing crew from a standing start. The assessment is conducted across the arc of a full inspection, with 8 to 12 hours on board for a standard oil tanker inspection. An inspector who arrives when the vessel is at anchor will observe the watch handover, engine room rounds, and officer briefings. One arriving during a port call will also observe cargo planning and communication with the terminal. Augmented inspectors arriving at the start of cargo will observe the cargo planning meeting, the independent pre-transfer verification, and the first hours of loading or discharge.
Observation categorisation under SIRE 2.0
SIRE 2.0 uses three severity levels for observations, replacing the binary observation/concern distinction of SIRE 1.0.
Low observations identify minor non-conformities that do not affect the safe operation of the vessel, environmental compliance, or regulatory standing, but require attention. Examples include isolated housekeeping items in low-consequence spaces, minor labelling discrepancies on non-critical equipment, and single-instance documentation gaps in records that are otherwise current. Low observations are recorded in the report and require an operator response, but they do not normally trigger a vetting hold.
Medium observations identify non-conformities that, if unaddressed, could develop into safety or environmental concerns. They may involve equipment in a degraded but not immediately unsafe state, procedure gaps in secondary systems, or crew competency shortfalls in non-critical areas. Medium observations require corrective action within a defined time window and are tracked by the commissioning Submitting Member’s vetting team.
High observations identify significant non-conformities affecting or imminently threatening safe operation, environmental compliance, or regulatory standing. A high observation can involve an inoperative safety-critical alarm, an expired statutory certificate that the inspector has confirmed is not in grace period, an oil content monitor that has been bypassed, or a demonstrated failure of crew to operate critical safety equipment. A high observation typically prompts the operator’s immediate corrective action and may result in the vessel being declined for charter or suspended from an approved supplier list until remediation is confirmed.
The previous SIRE 1.0 distinction, in which all negative findings were “observations” and a subset were flagged as “concerns,” was widely criticised for lacking granularity and for creating ambiguity in vetting decisions. The three-tier categorisation under SIRE 2.0 is more transparent and maps more directly to vetting outcomes.
Root cause analysis: the operator’s response obligation
Every observation raised in a SIRE 2.0 report, regardless of severity, requires the operator to submit a root cause analysis (RCA) and corrective action response. This is a structural change from SIRE 1.0, where RCA was effectively optional and many operators submitted brief corrective notes without any causal analysis.
The RCA must address three layers. First, the immediate cause: the specific deficiency found, in precise technical terms. Second, the underlying or systemic cause: what failure of process, maintenance planning, training, or management system allowed the immediate cause to occur. Third, the corrective and preventive actions: what has been done to address the immediate deficiency, and what systemic changes will prevent recurrence across the fleet.
OCIMF does not mandate a specific RCA methodology, but recognised frameworks include 5-Why analysis (iterating “why” until the systemic cause is reached), the Ishikawa fishbone diagram (mapping causes across machine, method, man, material, management, and environment categories), and the Tripod Beta or BowTie frameworks used in process safety management.
The operator’s RCA submission becomes part of the inspection report record and is visible to Submitting Members alongside the original observations. A vetting manager reviewing a SIRE report can therefore assess not only what was found but also how the operator has responded. A pattern of thin, formulaic RCAs across a fleet signals that the management system is not genuinely learning from inspection findings; this is itself a vetting concern that can influence approval decisions beyond the content of the observations themselves.
Operators with a mature ISM Code implementation generally find SIRE 2.0 RCA requirements less disruptive than those with legacy tick-box safety management systems. The ISM Code non-conformity and corrective action workflow, when genuinely applied, produces the data the SIRE 2.0 RCA requires. Where the ISM system has been treated as a paper exercise, the SIRE 2.0 RCA obligation exposes that gap.
TMSA and its relationship to SIRE
The Tanker Management and Self Assessment (TMSA) programme is OCIMF’s parallel framework for assessing the quality of a tanker operator’s shore-based management system. While SIRE assesses individual vessels through direct inspection, TMSA assesses the operator’s management structure, processes, and continuous improvement culture through self-assessment across twelve Key Performance Indicator (KPI) elements.
The twelve TMSA KPI elements are: (1) safety management system; (2) personnel management; (3) navigation safety; (4) cargo, ballast, and mooring operations; (5) environmental and energy management; (6) emergency preparedness; (7) incident reporting and investigation; (8) health, wellbeing, and safety; (9) security; (10) marine assurance; (11) new-build and acquisition; and (12) leadership, management, and accountability.
Each element has four stages of attainment. Stage 1 is the minimum baseline; Stage 4 represents continuous improvement embedded in the management culture. OCIMF recommends that operators achieve at least Stage 1 across all twelve elements as a prerequisite for SIRE compliance, with Stage 2 as the expected standard for established operators.
Oil major vetting departments use TMSA scores, submitted by the operator into the OCIMF system, alongside SIRE inspection reports. A vessel with a good SIRE record but an operator with a low TMSA score, or no TMSA submission, raises a concern that the vessel’s condition may be maintained only under inspection pressure rather than under systematic management. TMSA Stage 3 or 4 across all elements is a positive vetting factor that can offset modest SIRE observation counts, because it demonstrates that the management system has the capacity to self-correct.
The TMSA is a self-assessment, not a third-party audit. OCIMF relies on oil major vetting departments to review submissions for plausibility and to cross-reference them against SIRE findings. Operators who inflate their TMSA scores relative to their SIRE record create a consistency flag that vetting managers routinely note.
Oil major vetting decisions
The SIRE database is read by vetting departments within the oil major Submitting Members, charterers, and independent oil traders before each voyage nomination. A typical vetting decision integrates several data streams simultaneously.
The most recent SIRE inspection report is the primary input. The report is current for 12 months per OCIMF, but most vetting departments treat reports older than six months as requiring verification, particularly for vessels with recent observation records or operating in sensitive areas. Some oil majors require a SIRE report dated within 90 days for tankers nominated for specific high-sensitivity terminals.
The VPQ is reviewed alongside the report to verify that certificates remain current and that the vessel’s particulars are consistent with the fixture requirements. The operator’s TMSA submission is checked for stage attainment and for consistency with the SIRE findings. The vessel’s port state control detention record, accessed through the Paris MOU, Tokyo MOU, USCG, and other MoU databases, is reviewed for detentions or outstanding deficiencies. The vessel’s casualty and incident record, accessed through Lloyd’s List Intelligence, is also reviewed where available.
Vetting outcomes fall into several categories. Full approval means the vessel is accepted for the nomination without conditions. Conditional approval means approval is granted subject to specific remedial actions being confirmed before commencement of loading or within a defined post-fixture window. One-voyage approval is a time-limited acceptance that does not carry forward to future nominations. Rejection means the vessel is not accepted for that nomination; the commercial consequences depend on whether the owner or charterer bears vetting risk under the charter.
Some oil majors apply quantitative scoring: observation counts are weighted by severity and chapter, compared against a fleet-average benchmark for the vessel type and age, and the resulting score placed against an acceptance threshold. Others apply qualitative judgement supplemented by telephone interviews with the operator’s technical superintendent. The criteria are not uniform across oil majors, and a vessel rejected by one may be accepted by another on the same report if their thresholds differ.
Repeated rejections translate directly into lost charter opportunity and, for operators of larger fleets, into reputational effects that compound across new fixture discussions. A vessel with two consecutive SIRE reports carrying high observations, with thin RCA responses, will typically find itself excluded from major oil company programmes entirely, leaving it dependent on second-tier charterers whose acceptance criteria are more permissive but whose freight rates are correspondingly lower.
Charter party SIRE clauses
Modern tanker charter parties on the ASBATANKVOY, SHELLVOY, BPVOY, and similar standard forms contain SIRE clauses requiring the vessel to have a current SIRE report at the time of fixture and throughout the currency of the charter. The exact wording varies by form and by negotiation, but common clause structures include:
A clause requiring the vessel to be acceptable to a named oil major (for example, “acceptable to Shell”) or acceptable to any OCIMF Submitting Member. This triggers a vetting submission to that company’s vetting department; approval is a condition precedent to the charter commencing.
A clause requiring the vessel to maintain a SIRE inspection dated within a specified period (typically 12 months or six months) throughout the charter. If the SIRE expires during the charter, the owner must arrange a fresh inspection.
A clause making the vessel’s acceptance into a specific oil major approved supplier programme a condition of the charter, with failure to obtain or maintain that acceptance placing the vessel offhire.
Time spent rectifying SIRE observations is normally for the owner’s account under these clauses; the interaction with laytime and demurrage provisions depends on whether the delay occurs at a commercial port and whether the charterer can demonstrate that the delay was caused by the SIRE deficiency. The statement of facts for a voyage where SIRE issues delayed loading or discharge is a key document in any resulting claim.
If a vessel is rejected by the charterer’s nominated oil major after fixture, the question of which party bears the resulting costs and freight consequences depends on whether the charter contains a vetting warranty, whether the vessel’s SIRE record at the time of fixture was disclosed, and whether the rejection arises from a deterioration in condition occurring after fixture. These disputes are sufficiently common that P&I clubs and the London maritime arbitration community have accumulated a body of awards on the subject, though most are not publicly reported.
SIRE vs CDI: distinguishing the two regimes
The Chemical Distribution Institute (CDI) inspection programme is the principal industry inspection scheme for chemical tankers, tank containers, and road and rail tankers trading in the chemical and petrochemical industry. SIRE and CDI serve overlapping but distinct populations.
SIRE is operated by OCIMF and draws its Submitting Members principally from the major oil and energy companies: BP, Chevron, ExxonMobil, Shell, TotalEnergies, and similar principals. SIRE reports are used primarily to support oil major chartering decisions for crude oil tankers, product tankers, LPG carriers, and chemical tankers carrying oil major cargoes.
CDI is operated by the Chemical Distribution Institute and draws its membership from the chemical industry: BASF, Dow, INEOS, Lanxess, and similar chemical producers and traders. CDI inspections use the CDI Marine questionnaire (Marine-1 for seagoing chemical tankers), conducted by CDI-accredited surveyors, and the resulting reports are held in the CDI database accessible to CDI member companies.
A medium chemical tanker trading both oil major cargoes and chemical industry cargoes may need both a current SIRE report and a current CDI Marine inspection. The question sets overlap in some areas but differ in depth on specific chemical-handling and tank coating requirements that CDI’s chemical industry membership regards as essential and that SIRE does not cover to the same depth. The inspection fees are borne separately, and the scheduling is managed independently.
SIRE and CDI are not reciprocal: a CDI report does not substitute for a SIRE report in an oil major vetting decision, and a SIRE report does not substitute for a CDI Marine inspection for a chemical industry charter.
SIRE vs OVID: offshore service vessels
The Offshore Vessel Inspection Database (OVID) is OCIMF’s parallel programme for offshore support vessels (OSVs): platform supply vessels, anchor handlers, anchor-handling tug supply vessels (AHTS), accommodation units, offshore construction vessels, and similar offshore service tonnage. OVID was introduced to extend the OCIMF inspection database model to the offshore sector, where oil and gas operators were experiencing similar inconsistencies in vessel assessment that the original SIRE programme had addressed for tankers.
The OVID inspection questionnaire (OVIQ) mirrors the SIRE structure but addresses the specific equipment and operations of offshore service vessels. Dynamic positioning (DP) systems, from DP1 through DP3, are assessed against the IMCA M 103 framework and the vessel’s DP capability plot. Anchor-handling operations are assessed against OCIMF’s own anchor-handling guidelines. Helideck operations are assessed against the ICAO Annex 14 Volume II heliport standards and industry guidance. Dive support and well intervention operations are assessed where the vessel is equipped for them.
OVID Submitting Members are principally the major offshore operators: BP, Shell, TotalEnergies, Equinor, and similar majors with offshore production and development programmes. OSV owners whose vessels are chartered by these companies manage their OVID record with the same commercial importance that tanker owners assign to SIRE.
The observation categorisation, RCA obligation, and inspector accreditation structure in OVID mirror the SIRE 2.0 framework rather than the legacy SIRE 1.0 model.
SIRE 2.0 within the wider vetting and regulatory framework
SIRE sits alongside, not instead of, the mandatory regulatory regime. A vessel with a clean SIRE report but outstanding port state control deficiencies, a suspended classification society class notation, or an overdue ISM Code Document of Compliance will be rejected by vetting regardless of the SIRE record. SIRE supplements the regulatory framework by providing a more detailed, more frequently updated view of operational practice than PSC or class surveys alone can provide.
The relationship between SIRE and PSC is partly competitive and partly reinforcing. A vessel that maintains a strong SIRE record and a mature TMSA typically demonstrates, in practice, low PSC deficiency rates. The SIRE question set covers many of the items that Paris MOU and Tokyo MOU inspectors target, including hours of rest records, safety management system documentation, fire and life-saving equipment, and pollution prevention records. The PSC targeted inspection calculator covers the Paris MOU targeting factor that drives inspection selection.
Classification society surveys operate on a five-year continuous survey cycle, with annual surveys for specific items. The interval between class surveys means that a vessel might carry a clean class record while allowing operational practices to drift. SIRE inspections, conducted potentially several times per year depending on chartering intensity, close this gap. Some operators schedule self-assessments against the VIQ7 between SIRE inspections to maintain crew readiness.
Flag state surveys operate on frequencies mandated by the IMO instruments: SOLAS, MARPOL, ISM, ISPS, and MLC 2006 surveys at prescribed intervals. Flag state enforcement capacity varies substantially across registries; under open registries relying on recognized organizations for surveys, the effective survey standard depends on the class society rather than the flag administration. SIRE provides charterers with a quality signal that is independent of the flag and class structure.

Limitations of the SIRE programme
SIRE 2.0 is the most detailed industry inspection scheme in commercial shipping, but it has structural limitations that practitioners should recognise.
Snapshot limitation. A SIRE inspection covers 8 to 12 hours of an approximately 365-day annual operating cycle. Crew behaviour, maintenance discipline, and safety culture during those hours may not represent the vessel’s typical condition. Vessels whose operators focus on inspection performance may achieve strong SIRE records without fully internalising the underlying standards.
Geographic coverage gap. SIRE Submitting Members are predominantly the western oil majors. Vessels trading primarily under charter to non-member principals, or in trades outside the oil major network (for example, East of Suez spot markets or specific flag-to-flag crude trades), may face fewer SIRE inspections and therefore accumulate less VPQ and inspection history than similar vessels in the European or US-traded fleet. This makes cross-comparison of SIRE records across fleet segments unreliable.
Inspector variability. Despite the OCIMF quality programme, individual inspector thresholds for observation-raising vary. A medium observation raised by one inspector might not be raised by another for an identical condition. The rotational question design reduces but does not eliminate this variability. Operators with experience across multiple inspectors observe meaningful inter-inspector differences in observation rates for equivalent vessel conditions.
Self-assessment gap in TMSA. Because TMSA is a self-declaration, not an independent audit, operators with weak management systems can submit high TMSA scores that are not cross-validated until SIRE findings reveal the inconsistency. OCIMF has acknowledged this limitation and some oil major vetting departments conduct periodic TMSA verification visits for operators on their approved lists.
CDI and SIRE non-reciprocity. For chemical tankers, the requirement to maintain both a SIRE report and a CDI Marine inspection creates cost and scheduling pressure, particularly for smaller operators with thin shore staff. There is no industry-wide harmonisation between the two schemes, and the question sets overlap without being identical, requiring preparation for both separately.
Regulatory minimum floor. SIRE covers practices well above the statutory minimum. A vessel can be fully compliant with SOLAS, MARPOL, ISM, and MLC 2006 requirements and still carry SIRE observations for practices that, while lawful, fall below the industry good-practice standard that oil major charterers require. Operators sometimes misread SIRE observations as regulatory non-compliances; they are more often commercial standards that the oil major industry has set above the regulatory floor.
Lack of public transparency. SIRE reports are distributed only to Submitting Members, not to the public. A vessel’s SIRE record is not accessible to port state authorities, flag administrations, or the general public. PSC inspectors from the Paris and Tokyo MoUs cannot access SIRE reports. This closed-circulation model serves the commercial interests of OCIMF members but means SIRE data is not integrated into the regulatory risk-based targeting systems that PSC administrations use.
Practical implications for tanker operators
A tanker operator’s SIRE programme is a year-round commercial and operational function, not an event-driven preparation exercise. Operators who treat SIRE as a set of inspections to be passed tend to produce precisely the thin RCAs and superficial corrective actions that experienced vetting managers discount.
The VPQ must be accurate and current at all times. Operators of large fleets typically assign a dedicated vetting coordinator role responsible for VPQ maintenance across the fleet, tracking certificate expiry dates, scheduling inspections to maintain currency, and liaising with the SIRE system on operator data.
Crew familiarisation with VIQ7 does not mean distributing a PDF of the questionnaire and expecting crew to memorise it. The human element component is assessed on observed behaviour during normal operations; a crew member who can recite the BRM procedure but who did not apply it at the last watch handover will expose the gap under an Augmented Inspector’s assessment.
The ISM Code non-conformity system, when genuinely used, produces the data the SIRE 2.0 RCA requires. Operators with a functional ISM Code reporting culture find that near-misses and minor deficiencies reported and addressed internally before an inspection result in a demonstrably lower observation rate than operators who suppress non-conformity reporting to avoid creating paper records. The SIRE 2.0 RCA framework is designed to reward the former culture.
Mooring operations receive close scrutiny under VIQ7 Chapter 8, which references MEG4 requirements directly. The MEG4 fourth edition (2018) introduced the concept of the vessel-specific mooring plan based on a mooring system analysis for the vessel’s design berth conditions. Vessels without a current MEG4-compliant mooring plan, or with crew who cannot produce it or describe its contents, generate consistent observations in this chapter. Mooring forces and station keeping is covered in the linked article.
Cargo operations on chemical tankers and product tankers attract the highest concentration of Conditional questions and the highest potential for High observations. The tanker venting and tank cleaning and crude oil washing systems are assessed in detail. Marine inert gas systems and their operational logs are reviewed. The cargo system chapters of VIQ7 reference the ISGOTT sixth edition throughout; operators whose crew are not current with ISGOTT sixth edition guidance will find this in their inspection record.
