| 摘 要 由于全球温室效应日益加剧，气候变暖已经成为了备受关注的话题。在 2009年世界根本哈根气候大会上，各国商讨了《京都议定书》一期承诺到期后的后续方案，就未来应对气候变化的全球行动签署新的协议。我国身为制造大国，在节能减排方面做出了重要承诺，这对船舶行业来说既是挑战也是机遇。因此，在减少能耗的基础上提高船舶性能和营运能力，在今后的几年里将成为重点的研究方向。 本文给出了基于能效设计指数（EEDI） ，对57000 吨散货船进行耐波性的预报分析，主要研究内容如下： 1. 制定三种船型方案； 2. 分析比较57000 吨散货船在满载到港、压载到港等工况和不同海况下的耐波性能； 3. 计算57000 吨散货船的EEDI，分析其是否满足能效标准。 58511 毕业论文关键词：EEDI；耐波性；散货船 Abstract Duo to the increasing global warming, climate warming has become a topic of concern. In 2009, the world climate conference In Copenhagen, many countries discussed the “Kyoto Protocol” commitment period after the expiry of the follow-up program, the global action on the climate change signed new protocol. As a manufacturing power, China has made an important commitment to energy conservation and emission reduction, which is both a challenge and an opportunity for the shipping industry. Therefore, in the reduction of energy consumption based on improve ship performance and operation ability, in the next few years will become the focus of the research direction. This paper presents a 57000 DWT bulk cargo ship based on the energy efficiency design index (EEDI) based on using strip theory seakeeping prediction and analysis . The main research contents include： 1. Formulate three different blocks of ships; 2. Analysis and comparison seakeeping ability of 57000 DWT bulk cargo ship in loaded arrival,ballast arrival operating conditions and different wave conditions; 3. Calculate the EEDI of the 57000DWT bulk cargo ship and determine whether they satisfy the energy efficiency standards.
