新船能效设计指数主要参数影响分析

为识别和分析新造船能效设计指数（EEDI）计算公式中主要计算参数的影响程度，对EEDI计算公式进行了解析，建立了EEDI的简化分析模型。根据对10年来散货船数据统计，通过简化模型对某57000dwt散货船的分析，得出了主机功率，航速和载运能力3个因素对EEDI的影响程度的高低排序。并对4种船型的船舶载运能力与其相应的EEDI作了比较分析，提出了相应的建议。

Analysis of Major Influencing Factors on Energy Efficiency Design Index of Newbuildings

In order to identify and analyze the major calculation parameters in the energy efficiency design index （EED1） formula for newbuildings, this paper elaborates on the EEDlcalculation formula and establishes a simplified EEDlmodel for analysis. Based on the bulk carriers statistical data collected in the recent decade, the influences of three factors, i.e. main engine power, speed and loading capacity, on EEDI are analyzed and ranked in order for a 57 000dwt bulk carrier using the simplified model. Moreover, comparative analysis is carried out for four ship types in terms of their loading capacity and the corresponding EEDI, with some suggestions proposed.
