Oshima ECO-ship 2020 The open hatch bulk carrier of the future
Oshima ECO-ship 2020 - Objectives • Environmental friendly • Energy efficient • Cost-effective • Flexible operations
Design basis Market and logistics study Basis for selection of main particulars and technical solutions Operational profiles and trading routes identified Basis for fuel consumption calculations Open Hatch Bulk Carrier segment: Many port calls Pulp trades Few ballast voyages Average load level 77% 3
Concept overview • Main features: • LNG fuelled – LNG as only fuel on board • Wide air lubricated twin skeg hull • Flexible propulsion and power generation systems • Waste heat recovery • Composite hatch covers • Large capacity electric deck cranes
Optimised to fit operational profile Wide twin skeg hull Seaworthy Bow Air lubrication Flipper fins Reduced fuel consumption Low total resistance Calm water Waves High propulsive efficiency Hull
LNG fuelled • LNG only, no fuel oil for propulsion or power generation • Fully compliant with existing and future expected emission requirements • ECA and EU port regulations • IMO Tier III regulations • No SOx and particulate emissions • Significant reductions of CO2 • Clean working environment • No risk for accidental oil pollution • LNG tank location in aftship • 4 C-type pressurised tanks • Total tank capacity 3,000 m3
Machinery and propulsion systems by Rolls-Royce Marine • 2 lean-burn 4-stroke medium speed gas engines, 2 x 4,000 kW • 1 auxiliary gas engine, 1 x 1,400 kW • Hybrid Shaft Generators, PTI/PTO mode • Frequency converters • Waste heat recovery • PROMAS, integrated propeller and rudder • Low fuel consumption • High energy efficiency • Twin screw redundancy • Flexible propulsion and power generation • Excellent manoeuvrability
Operational solutions All-electric deck machinery • Large capacity electric jib cranes, 4 x 75t • High cargo handling efficiency • Reduced energy consumption Composite materials • Hatch covers • Significant weight reduction • Easy handling by deck crane (no hydraulic systems) • Less maintenance
The ECO-Ship is commercially viable • Compared to a conventional Oshima OHBC, the ECO-ship requires an additional investment of about 23 MUSD • This extra investment is expected to be earned back within 10 years • The ECO-ship improves the expected net present value before tax by 38 MUSD over a lifetime of 25 years
Concluding remarks • Cost-effective • 10 years pay-back time • Improved lifetime net present value of 38 MUSD • Flexible operations • Machinery and propulsion system • Large capacity deck cranes • Composite hatch covers • Environmental friendly • No emissions of SOx or particulates • 90% NOx reductions • CO2 reductions of at least 50% compared to base case • Energy efficient • LNG fuelled • Waste heat recovery • Electric deck machinery
