【摘要】：随着深海油气开发和大型海上工程的发展,深水半潜起重铺管船作为海洋油气开发过程中的重要装备也越来越受到大家的重视。其中大型半潜起重铺管船(SSCV)虽然外表傻大粗笨,但起重量大、稳性好、环境适应性强,因此其在未来的海洋工程中优势明显。但由于全球数量稀少,因此迫切需要对该船型的关键技术进行研究。本文通过理论计算和模型试验等方法,详细研究了半潜起重铺管船型的阻力性能、结构强度、起重作业稳性、动力定位能力、水动力性能等关键的船舶性能,为进一步掌握该船型的关键技术提供了帮助。本文分析了半潜起重铺管船的船型特点,主要研究了对船舶性能有重要作用的立柱数量、大小、布置位置特点,提出了八立柱和十立柱两个船型方案,并对这两个船型方案在空船重量、起重作业稳性、动力定位性能、水动力性能等方面进行比较研究。通过理论计算和模型试验等方法,比较两个船型在各方面的优劣,为最终的船型选择提供参考。本文研究成果可应用于深水半潜起重铺管船的船型设计中,可为船型设计和总体性能预估提供帮助。
[Abstract]:With the development of deep-sea oil and gas development and large-scale offshore engineering, deep-water semi-submersible hoisting tube-laying ship as an important equipment in the process of offshore oil and gas development has been paid more and more attention. SSCV (large semi-submersible hoisting and pipe laying ship) has the advantages of large lifting weight, good stability and strong environmental adaptability, although it is stupid and clumsy in appearance, so it has obvious advantages in the future marine engineering. However, due to the scarcity of global numbers, there is an urgent need to study the key technologies of the ship form. In this paper, the resistance performance, structural strength, hoisting stability, dynamic positioning ability and hydrodynamic performance of semi-submersible hoisting tube-laying ship are studied in detail by theoretical calculation and model test. It is helpful for further mastering the key technology of the ship form. This paper analyzes the ship type characteristics of semi-submersible hoisting tube-laying ship, mainly studies the number, size and location characteristics of the columns which play an important role in the ship's performance, and puts forward two ship types, eight and ten pillars. The two schemes are compared in terms of the weight of the empty ship, the stability of the lifting operation, the dynamic positioning performance and the hydrodynamic performance. By means of theoretical calculation and model test, the advantages and disadvantages of the two ship types are compared in order to provide a reference for the final selection of ship types. The research results in this paper can be applied to the ship form design of deep-water semi-submersible hoisting tube-laying ship, and can be helpful for ship form design and overall performance prediction.
