| Ship Energy Efficiency Design Index (EEDI) went into force since1stJuly2013,the limitation of EEDI will further decrease by30%on the basis of current referenceline, that will be a big challenge to marine industry. On the other hand, fuel cost is thelargest proportion of ship’s life cycle cost, hereby, reduce fuel consumption is thebest solution to control operating cost for shipping company.The research on shipping market shows that slow steaming, long-term upwardtendency of oil price and scaling-up container ship are leading tendencies nowadays.This thesis studies on and compares with different energy-saving methods; combineswith analysis to the ship’s life-cycle cost. The bulbous bow retrofit project of a9,600TEU container vessel was given as sample to explain the process, schedule,investment, and payback of a typical energy-saving improvement project.To expound the necessity and broad applicability of energy-saving improvement,regression analysis, case analysis was applied qualitatively and quantitatively todefine the market need and economic performance.Market analysis and case study results show that improving energy efficiency istop priority need of ship owner now. Energy efficiency improvement can be achievedthrough a variety of methods, and it should be applied to specific vessel according topractical situation. Even for operating vessel which has more limitations from retrofit,a local modification to hull form and engine system can significantly reduce fuel oilconsumption, and payback the investment in a short time. |
