大型海缆船技术发展现状及趋势

State-of-the-art and Development of Large Cable Layer

海缆船的电缆装载能力是海底电缆工程的关键指标,其铺缆装备的能力和效率也成为制约海缆船作业效率的重要因素。文中首先介绍了海缆船的主要应用方向,分析了国内外海缆船的技术现状。通过研究国外大型海缆船的技术现状,归纳了大型海缆船在船型及主尺度、作业方式和主要性能的技术特点;然后推出了两型分别用于近海和远海航区的5 000吨级海缆船设计方案,研究了两型船主要技术参数、作业系统及能力;最后对未来大型海缆船的发展进行展望,初步探讨了大型海缆船的四个发展方向。

The cable loading capacity of the cable layer is the key indicator of submarine cable laying project,and the capacity and efficiency of the cable laying equipment become an important factor restricting the operation efficiency of the cable layers.It firstly introduces the main application of the cable layers,and analyzes the stateof-the-art of the cable layer both at home and abroad.The technical characteristics of the large cable layers are summarized in the ship type and main dimensions,the operation mode and main performance by the investigation of the state-of-the-art of the foreign cable layers.The design plans of the two 5 000 tonnage cable layers that are separately used for the offshore and seagoing area are presented to study the main parameter,operation system and capacity of both ships.Finally,the development of the large cable layers is prospected to preliminarily discuss the four development directions of the large cable layers.
