SHIP HULL DESIGN FOR FUEL EFFICIENCY - A MATHEMATICAL DESCRIPTION OF DESIGN PARAMETERS INFLUENCE ON SHIP DESIGN

摘要

The cost of energy, economic climate, social responsibility and emerging international regulatory requirements to reduce emissions are all drivers in modern ship design. International regulatory requirements on environmental performance and cost effectiveness as main drivers in modern ship design has becoming a matter of increasing awareness after IMO has adopted mandatory energy-efficiency design index (EEDI) under Annex VI of IMO's pollution prevention treaty (MARPOL), resolution MEPC.203(62), to address the emission of air pollutants from ships. EEDI is an index quantifying the amount of carbon dioxide that a ship emits in relation to the goods transported. If the required EEDI level is attained, ship designers and builders are free to use the most cost-efficient solutions for the ship to comply with the regulations. This paper is intended for discussion of parameters and assumptions included in the resistance objectives, constraints in hull form design and design variables used in hull form optimization.
