摘要
根据国际海事组织第62次会议相关规定时限,新造船舶的能效指数(EEDI)进行强制测量和计算,而EEDI计算的核心参数是修正试航船舶的航速和轴功率。文章主要利用当前常用的修正计算理论对某型号散货船试航的实测航速和轴功率进行修正计算,同时改变风速、浪高、浪的入射角等海况参数,采用相关修正计算数学模型,对船舶在不改变航速的条件下对应的轴功率修正值进行计算分析,并总结各海况参数对船舶轴功率修正值的影响规律。
According to the relevant time limit of the 62nd meeting of the International Maritime Organization, the energy efficiency design index (EEDI) of the newly built ship is forcibly measured and calculated, and the core parameter of the EEDI calculation is to modify the speed and shaft power of the trial ship. The article mainly uses the commonly used correction calculation theory to correct the calculated measured speed and shaft power of a certain type of bulk carrier, and changes the sea state parameters such as wind speed, wave height and wave incident angle, and uses the relevant correction to calculate the mathematical model. The corresponding shaft power correction value is calculated and analyzed without changing the speed of the ship, and the influence law of each sea state parameter on the ship shaft power correction value is summarized.
