摘要
结合IMCA相关规范,介绍预估船舶动力定位能力的方法,阐述动力定位能力的计算流程,分析常见的风、流系数的区别与适用范围,给出适用于海洋工程辅助船的风力及水流力计算系数,编制船舶动力定位能力分析系统。以海洋工程辅助船为对象,预估其最大动力定位能力及在定海况下各桨推力使用情况,分析各类型系数在计算中的结果,并结合试验验证该系统的可靠性。
Based on the IMCA specifications, the analysis method and algorithm of position keeping capability of Dynamic Positioning（DP） systems is introduced; the coefficients of 1MCA and （）CIMF are discussed, and a new coeffi cient of wind and current for offshore support vessels（OSV） is proposed; a DP capability analysis system is put for ward. The proposed analysis system has been used for predicting the DP capability of an （）SV. The calculation is conducted with different coefficients, including the coefficients of IMCA, OCIMF and the proposed one. The results indicate that that the proposed coefficients give a result which is very close to that of test, thereforc, bctter for （）SV DP than others.
