摘 要稳性是保证船舶和平台安全的一项重要性能，是船舶安全航行的基本保障，也是 船舶检验的最主要内容之一。良好的稳性能使船舶和平台在航行、操作等工况下，遇 到风浪等外力干扰后能更快地恢复到原先的平衡位置。79089

本课题选取了七千吨钻井辅助船来进行稳性研究，该船携带钻井平台所需的全套 辅助装置，并为钻井平台提供管子、泥浆等物资，为钻井平台提供动力、备用品及供 人员住宿等功能。钻井辅助船主要用来为钻井模块提供支持和服务，为海洋钻井工程 提供现场支持服务，而本身不具有独立的钻井能力。

本课题的主要目的是对钻井辅助船在满载出港以及操作两种工况下进行稳性校 核，为船舶在其他工况下的稳性校核方面提供参考。

1、本文给出了 ABS 中近海供应船和钻井辅助船的稳性横准要求，列出稳性计算 的原理，介绍该船的主要信息，并遵照横准要求对该船进行稳性校核。

2、本文利用犀牛软件建立钻井辅助船的三维模型，通过 GHS 软件进行舱室建模， 通过研究设定钻井辅助船的满载出航工况和操作工况的装载，利用 GHS 软件对这两 种工况进行完整稳性校核。

3、根据校核结果，与两种稳性横准要求进行对照，对比分析后得出结论：该钻 井辅助船在满载出港和操作工况下稳性都能满足 ABS 的稳性横准要求。

Abstract Stability is one of the most important properties of ship and platform security assurance。 Stability is a basic guarantee for the safe navigation of ships and one of the main content of ship inspection。 Good Stability of the ship and platform in the full load condition and operation condition can return to the original balance position quickly after encountering storms and other external interference。

This topic selects the 7000 tons of drilling tender to carry out research of its stability。 The tender carries a full set of auxiliary equipment for drilling platform and provides a pipe, mud and other supplies for the drilling platform to provide power for the drilling platform, equipment and staff accommodation and other functions。 The drilling tender is mainly used to provide support and services for drilling module, and provide on-site support services for offshore drilling engineering, but itself does not have independent drilling capacity。

The main purpose of this subject is checking stability of drilling tender in full load departure condition and operation condition and provide a reference for other conditions。

1、In this subject, the stability of the ABS in the offshore supply ship and the drilling

tenderof the requirements of the standard, lists the principle of stability calculation, the ship's main information and in accordance with the requirements of the ship's stability check。

2、In the subject, we use rhino software to establish drilling tender 3D model and

compartment model by GHS software。 Through the research setting drilling tender with sail and operating condition of the loading and complete stability checking by GHS software

3、According to the verification of the results, and two stable cross quasi requirements

for control and comparative analysis concluded: the drilling tender in full load departure condition and operation condition of stability can meet the stability of the ABS cross quasi requirements。

Key words: Stability; Loading Condition; Drilling Tender; Check。
