摘　　要：系泊问题是近岛礁中型浮式结构物设计和应用过程中需关注的关键问题之一。根据近岛礁平台作业区域的地质、地形特点和环境条件,采用张紧式系泊形式,基于集中质量法对该浮体系泊系统开展数值模拟研究,分析平台的六自由度运动、系泊缆张力和锚抓力等定位性能。研究发现:在给定的环境条件下,张紧式系泊系统的张力在近岛礁平台运动过程中呈现出稳定的特性,系统的定位性能较好;在采用张紧式系泊系统开展系泊作业时,其锚点张力较大,在设计过程中需注意选用合适的锚桩,确保系泊系统具有足够的锚抓力。Mooring is one of the key issues that need to be paid attention to in the design and application of medium-size floating structures near islands and reefs.Therefore the taut mooring system is adopted according to the geological and topographic characteristics and environmental conditions of the platform operation site,and the lumped mass method is used for the numerical simulation of the platform to investigate the 6-DOF motions,mooring line tensions,anchor gripping forces and etc.The result shows that the tensions of the taut mooring system under the designated environment have stable characteristics during the movements of the platform near islands and reefs,and the positioning adaptability of the platform is good.As the taut mooring system is used,and the anchor forces are large,it is important to select proper anchor piles in the design to ensure that the mooring system has enough gripping force.
