Container Ship
X112. IMO GHG Strategy, CII, EEXI and EU Maritime RegulationDefinition
Ship type with dedicated EEDI Phase 3 30 percent reduction factor and dedicated AER reference line.
A container ship carries standardized intermodal containers in cellular holds and stacked on deck with twistlocks and lashing bridges. Capacity is stated in twenty-foot equivalent units, from feeder vessels under 3,000 TEU to ultra-large ships above 24,000 TEU. Under MARPOL Annex VI the EEDI sets container ships a 30 percent reduction factor in Phase 3 and a dedicated reference line, reflecting their high design speeds. Stability and lashing depend on accurate container weights, so SOLAS VI/2 requires a verified gross mass before loading.
