大型小水线面双体特殊用途船公约合规设计

Large SWATH Special Purpose Ship Conventions Compliance Design

小水线面双体(SWATH)特殊用途船的结构形式和作业功能与常规单体船有很大区别,有必要探究适用于常规单体船的设计和建造标准是否也适用于小水线面双体船,并分专业模块厘清小水线面双体船所遵循的设计建造标准和存在的典型设计问题。针对小水线面双体船为满足公约关于常规船的要求而在设计上存在的一些典型问题,逐项找寻解决方案。通过目标船的设计,总结相关设计经验,可为同类型船舶的设计、建造或改装提供有价值的参考。研究发现:小水线面双体特殊用途船的设计建造标准分专业模块、按船上所载总人数指向公约货船或客船要求;总体上适用于单体船的要求也适用于小水线面双体船,但在个别要求的合规性上需对小水线面双体船采取替代或等效的设计方案。

The structural form and operation functions of small water-plane area twin-hull(SWATH)special purpose ships are very different from those of conventional mono-hull ships.It is necessary to explore whether the design and construction standards applicable to conventional mono-hull ships are also applicable to SWATH ships,and clarify the design and construction standards followed by SWATH ships and corresponding typical design problems by professional modules.In view of some typical problems existing in the design of target SWATH special purpose ship to meet the requirements of the conventions on conventional ships,solutions are sought one by one.Through the design of the target ship,the relevant design experience has been summarized,which could provide valuable reference for the design,construction or conversion of similar ships.It is found that:the design and construction standards for SWATH special purpose ships are divided into professional modules,which point to the requirements of convention cargo ships or passenger ships based on the total number of persons carried on board;in general,the requirements applicable to mono-hull ships are also applicable to SWATH ships,but alternative or equivalent design measures have to be adopted for this ship type in terms of the compliance of some concrete requirements.
