摘要
三用工作船(Anchor Handling Tug Supply Vessel,AHTS)不仅能对钻井平台等大型结构物进行远洋拖航、起抛锚作业和供应物资,而且能在特定情况下用作紧急救援船。AHTS在不同作业工况(如拖带作业、全速航行、经济航行、动力定位作业等)下所需求的动力和用电负荷有很大区别,若在设计初期综合考虑各种作业工况,并根据各种作业工况下的负荷情况来合理配置推进及电站系统,则可在保证船舶正常作业的同时降低船舶初期投入成本和后期使用成本。结合中大型AHTS的工作特点,对2种主流的推进及电站系统配置进行深入分析,研究探讨在今后设计中如何选择和优化推进及电站系统的配置。
Anchor Handling Tug Supply (AHTS) vessel can be used not only for anchor handling, provision supply and large offshore structures towing such as drilling platforms towing, but also for emergency rescues under special circumstances. Therefore, the required propulsion power and electrical loads are very different under different operation conditions (e.g. towing, full speed cruising, economical cruising and dynamic positioning). If all the operation conditions could be considered comprehensively in the preliminary design stage to have the propulsion power and electrical loads deployed properly, the operations of the vessel can be ensured with lower initial investment and lower operational costs.Further analysis on the configurations of two types of the major propulsion and generator system is also carried out according to the operational characteristics of AHTS to discuss the selection and optimization of the configuration for the propulsion and generator system of the future.
