1.1 本指南涵盖了船舶轻型船舶特性的确定。在本标准中，船舶是传统的船体成型船舶。稳定性测试可以被视为两个独立的任务；轻量测量和倾斜实验。大多数船舶在完工后和重大改装后都需要进行稳定性测试。通常在平静的天气条件下在近海进行，通常要求船舶停止使用，以准备和进行稳定性测试。根据常规（对称）船舶稳定性试验确定的三个轻型船舶特性是位移（“ 显示 “”，纵向重心（“” LCG公司 “”和垂直重心（“” 公斤 ”). 横向重心（“ TCG公司 ）也可用于移动式海上钻井装置（MODU）和其他围绕中心线不对称的船舶，或其内部布置或舾装可能从偏心重量形成固有列表的船舶。由于其性质，本指南中未具体提及的其他特殊考虑可能对某些MODU是必要的。本标准不适用于张力腿平台、半潜式平台等船舶- 潜水器、硬壳充气船等。 1.2 如果使用传统的预定义静水压特性，则1%纵倾或4%横倾等限制适用。这是由于水线面积的急剧变化。如果要计算每次移动时的静水压特性，例如使用计算机程序，则这些限制不适用。 1.3 以英寸-磅为单位的数值应视为标准值。本标准不包括其他计量单位。 1.3.1 例外情况- 稳定性试验可使用其他单位，但试验结果应以与船舶吃水标志、纵倾和稳定性手册或提供的类似稳定性信息相同的单位和坐标系报告。 1.4 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.5 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 根据轻型船舶的特性，可以计算船舶在所有装载条件下的稳定性特性，从而确定船舶是否满足适用的稳定性标准。稳定性测试的准确结果在某些情况下可能决定船舶及其船员的未来生存，因此测试的准确性无论怎样强调都不为过。试验期间容器和环境的条件很少理想，因此，稳定性试验很少按计划进行。 如果容器不是100 % 完成后，天气不太好，水箱中有水或船厂垃圾，本应清洁干燥等等，然后负责人必须立即决定是否接受与计划的差异。完全理解稳定性测试背后的原理，了解影响结果的因素是必要的。

1.1 This guide covers the determination of a vessel’s light ship characteristics. In this standard, a vessel is a traditional hull-formed vessel. The stability test can be considered to be two separate tasks; the lightweight survey and the inclining experiment. The stability test is required for most vessels upon their completion and after major conversions. It is normally conducted inshore in calm weather conditions and usually requires the vessel be taken out of service to prepare for and conduct the stability test. The three light ship characteristics determined from the stability test for conventional (symmetrical) ships are displacement (“ displ ”), longitudinal center of gravity (“ LCG ”), and the vertical center of gravity (“ KG ”). The transverse center of gravity (“ TCG ”) may also be determined for mobile offshore drilling units (MODUs) and other vessels which are asymmetrical about the centerline or whose internal arrangement or outfitting is such that an inherent list may develop from off-center weight. Because of their nature, other special considerations not specifically addressed in this guide may be necessary for some MODUs. This standard is not applicable to vessels such as a tension-leg platforms, semi-submersibles, rigid hull inflatable boats, and so on. 1.2 The limitations of 1 % trim or 4 % heel and so on apply if one is using the traditional pre-defined hydrostatic characteristics. This is due to the drastic change of waterplane area. If one is calculating hydrostatic characteristics at each move, such as utilizing a computer program, then the limitations are not applicable. 1.3 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard. 1.3.1 Exceptions— Other units may be used for the stability test, but the test results should be reported in the same units and coordinate system as the vessel’s draft marks and Trim and Stability Book or similar stability information provided. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 From the light ship characteristics one is able to calculate the stability characteristics of the vessel for all conditions of loading and thereby determine whether the vessel satisfies the applicable stability criteria. Accurate results from a stability test may in some cases determine the future survival of the vessel and its crew, so the accuracy with which the test is conducted cannot be overemphasized. The condition of the vessel and the environment during the test is rarely ideal and consequently, the stability test is infrequently conducted exactly as planned. If the vessel is not 100 % complete and the weather is not perfect, there ends up being water or shipyard trash in a tank that was supposed to be clean and dry and so forth, then the person in charge must make immediate decisions as to the acceptability of variances from the plan. A complete understanding of the principles behind the stability test and a knowledge of the factors that affect the results is necessary.
