考虑波浪作用的油船极限靠泊条件

The Berthing Condition of Oil Tanker Under the Acting of Wave

介绍了采用两种能量法计算靠泊过程中油船对护舷碰撞荷载 :一种是按照我国港口荷载规范中公式 ,另一种是按照国际航运会议委员会推荐公式。计算中考虑了波浪对油船运动的影响 ,克服了以往没有考虑这一影响的不足。计算针对某一海洋平台进行 ,给出了油船极限靠泊条件 ,可为油船靠泊时确定在风和水流及拖船作用下油船靠泊速度提供依据。

Two energy methods for calculating the impacting loads of oil tanker on the fenders are introduced.One is the formula given in the port engineering criteria by Chinese port authority,another is the formula recommended by the international conference committee of ship navigation.A strip method is used in this paper to calculate the six degree of freedom motions of an oil tanker in waves,and the effect of the motions of the oil tanker on the impacting energy is considered.Based on the results,the maximum transverse velocity of the oil tanker is obtained,which is the allowable transverse velocity of the oil tanker under the combined action of wind,tide and the tugboat when the tanker is berthing to an offshore platform.
