【摘要】：船舶正在不断朝着大型化的方向发展,而国内许多港口水深条件使得大型船舶尤其是大型油轮的进出受到限制。为使原油运输作业更加安全、高效,增加港口的综合竞争力,国内较多港口都已成功进行了大型油轮海上过驳减载作业,其中,系缆布置对于保障过驳作业的安全进行具有重要意义,而石油公司国际海事论坛仅简单推荐了一个最低过驳系缆布置标准,在国内港口也曾出现过原油过驳作业断缆事故。因此,对海上原油过驳作业系缆布置进行研究具有重要的意义。从事海上原油过驳作业的双船系统在外界环境作用下最终会稳定于风浪流的合力方向,此时该系统达到外力的平衡状态,两者间通过缆绳等索具达到内力的平衡状态。而对于某一特定系缆布置方式,不同功能的缆绳受力大小、对减小两船相对运动的作用随气象海况的不同而发生变化,因此讨论船舶系缆布置不仅要考虑不同气象海况对双船系统的外界作用力,还要考虑缆绳数量、缆绳系固位置等因素。本文在石油公司国际海事论坛推荐的最低海上原油过驳作业系缆布置要求基础上,了解查阅船靠码头的系泊相关资料、常用系缆布置方式后,结合油轮海上原油过驳中系缆布置作业特点,以缆绳系固位置、缆绳数量,是否增加横缆为系缆布置的影响变量设计了不同的计算方案。再利用专业系泊力计算软件OPTIMOOR计算得出了不同风浪、流夹角作用下的缆绳张力、两船输油软管处相对运动量数据,运用统计学中方差和极差分析法对以上数据进行统计分析,以均衡缆绳张力、控制两船船中相对运动幅度和高效利用缆绳为目标,给出了系缆布置的优化建议。最后利用Transas全任务航海模拟器进行了同等试验条件下的模拟,对照结果表明本文提出的系缆布置建议能使原油过驳作业更加安全经济,可以为后续进行海上原油过驳作业研究提供一定的参考。
[Abstract]:The ship is constantly developing in the direction of large scale, and the water depth conditions of many ports in China have limited the import and export of large ships, especially large oil tankers. In order to make the operation of crude oil safer, more efficient, and increase the comprehensive competitiveness of the port, many ports in China have done large oil tanker sea refutation and load reduction operations. The cable arrangement is of great significance to ensure the safety of the refutation operation, and the International Maritime Forum of the petroleum company simply recommends a minimum refutation cable arrangement standard, and there has been a crude oil refutation accident in the domestic port. Therefore, it is very important to study the cable arrangement of the offshore oil refutation operation. The double ship system, which is engaged in the offshore oil refutation operation, will eventually stabilize the force direction of the wind and wave flow under the external environment. At this time, the system reaches the balance state of the external force, and the balance state of the internal force is reached by the cable and other rigging. For a certain cable arrangement, the force size of the cables with different functions is reduced. The effect of the relative motion of the small two ships varies with the different meteorological sea conditions. Therefore, the discussion of the cable arrangement of the ship's system should not only consider the external forces of the different weather sea conditions on the double ship system, but also consider the quantity of the cable and the position of the cable system. The minimum offshore oil refutation recommended by the International Maritime Forum of the oil company is recommended in this paper. On the basis of cable arrangement requirements, we can find out the related data of mooring on the ship's dock. After the cable arrangement, it combines the characteristics of the cable arrangement in the oil refutation of the oil tanker, and designs the different calculation schemes for the cable system position, the quantity of the cable and whether the cable is the influence variable of the cable arrangement, and then the professional mooring force is used. The calculation software OPTIMOOR calculates the cable tension under the action of different wind waves, the flow angle and the relative motion data at the two ship's oil hose. The statistical analysis method of variance and pole difference is used to analyze the above data, in order to balance the tension of the cable, control the motion amplitude and the high efficiency of the use of the cable as the target. The optimization proposal of the cable arrangement is made. Finally, the simulation of the Transas full mission navigation simulator is carried out under the same test conditions. The comparison results show that the proposed cable arrangement proposal can make the crude oil refutation more safe and economical, and can provide some reference for the further study of the offshore oil refutation operation.
