Prolific Japanese constructor of bulk carriers, Oshima Shipbuilding, has readied its design portfolio to meet Energy Efficiency Design Index (EEDI) Phase 3 criteria, writes David Tinsley. While 30 recent bulker deliveries from the yard at Saikai City in Nagasaki Prefecture already satisfy the impending, tighter requirements, a Phase 3 rating has now been applied across 13 Oshima designs conceived for standardised or serial production. The revised offering spans handysize to post-Panamax tonnage. Significantly, the enhanced EEDI level that will become mandatory for bulker newbuilds in 2025 has been achieved without departing from conventional, oil-fuelled propulsion. Although adaptation to alternative fuels has been considered by the shipbuilder as a means of Phase 3 compliance, Oshima has instead chosen the path of hull form optimisation and energy saving appendages together with studied selection of propeller and main engine.
