摘　　要：坞式半潜船为海上特种作业船型,满足DNV Noble Denton《海上运输指南》相关海上潜装作业标准要求,具有优良的耐波性能。在方案设计阶段为了优化、确定船舶主尺度、线型等重要参数,基于三维势流和设计波法理论,应用BV船级社开发的HydroSTAR软件,对目标船在高海况下波浪运动响应进行计算分析。纵摇和横摇幅值计算结果表明,在坞式半潜沉浮作业时通过调整浪向来保证作业安全性是十分必要的。As a special type of marine operation ship,the dock-type semi-submersible vessel is in compliance with the requirements of the relevant offshore submersible operation standards of Guidelines for Marine Transportation issued by DNV Noble Denton and has excellent seakeeping performance.Based on the theory of three-dimensional potential flow and design wave approach,the HydroSTAR software developed by BV was applied to calculate and analyze the wave motion response of the target vessel under high sea conditions in order to optimize and determine the important parameters such as the main dimensions and hull lines in the scheme design stage.The calculation results of pitch and roll amplitude showed that it was very necessary to ensure the operation safety by adjusting the wave direction during the offshore semi-submersible diving and floating operation.
