EEDI EEDI（Energy Efficiency Design Index）是国际海事组织（IMO）制定的船舶在航CO2排放指标，自2013年1月1日起实施。EEDI的实施对船厂和设计院都是一个挑战，对绿色船舶的开发和优化提出了更高的要求。另一方面，随着船舶向高技术、大型化、专业化方向发展，在概念设计阶段考虑各学科之间的相互耦合变得越来越紧迫，本文提供了一种应用于概念设计阶段的有效方法，以阿芙拉型油轮为例进行多学科优化研究，实例表明了所提出的多学科优化方法的实用性和优越性。
EEDI(Energy Efficiency Design Index) is a CO2 emission index of ship in navigation,which is laid down by IMO and has been enforced since January 1,2013.Enforcement of EEDI is a challenge for shipyard and design institute,and put forward higher requirements for development and optimization of green ships.On the other hand,with the ships' development trend towards high technology,large-scale and specialization,It becomes more and more urgent to consider the mutual coupling between various disciplines in conceptual design stage.This paper provides an effective method applied in conceptual design stage,to carry out a study on multidisciplinary optimization,while an Aframax tanker is taken as an example.The given example demonstrates the practicability and superiority of the proposed multidisciplinary optimization method.
