【摘要】：为了解决天然河流水位高差与航道宽度季节性变化大而导致的LNG船舶燃料加注困难的问题,提出了一种介于岸基式加注站与加注船之间的新概念——内河LNG燃料加注趸船。为此,分析了LNG加注趸船概念提出的背景、船型的市场需求和分级管理理念,并从安全屏障角度讨论了LNG加注趸船的安全设计原则,重点阐述了LNG的安全储存理念及其实现手段,从储罐的选型、设计压力的确定、选材、泄漏防护原则及其试验验证等方面明确了LNG安全储存的实现方式。在LNG系统方面,提出了LNG补给及加注系统的工艺安全要点,阐明了轻型加注臂的技术特点,同时论述了锚泊与系泊的安全考虑。结论认为:①基于分级管理,采用国际海事组织的C型独立罐,并进行工艺安全、锚泊和系泊设计的LNG加注趸船是可行的;②至2025年,我国长江和珠江上500 m~3规模LNG加注趸船的需求量将接近30艘;③该船型的安全性、可靠性已经得到了实践的检验,目前已发展出第四代船型。
[Abstract]:In order to solve the problem of LNG ship fuel filling caused by the seasonal variation of natural river water level height difference and channel width, a new concept, inland river LNG fuel filling barge, is put forward, which lies between shore-based filling station and filling ship. This paper analyzes the background of the concept of LNG filling barge, the market demand of ship type and the concept of hierarchical management, discusses the safety design principle of LNG filling barge from the point of view of safety barrier, and emphatically expounds the safe storage concept of LNG and its realization method. From the aspects of tank selection, design pressure determination, material selection, leakage protection principle and test verification, the realization of LNG safe storage is clarified. In LNG system, the key points of process safety of LNG replenishment and injection system are put forward. The technical characteristics of light injection arm are expounded, and the safety considerations of mooring and mooring are discussed. It is concluded that based on the hierarchical management, the type C independent tank of the International Maritime Organization (IMO) is adopted and the process safety is carried out. The LNG filling barges of mooring and mooring design are feasible from 2 to 2025. The demand for 500mm3 LNG pontoon on the Yangtze and Pearl River in China will be close to the safety and reliability of this type of barge, which has been tested in practice. At present, 4th generation ship has been developed.
