蝶形布置油码头平面设计要点

对港口工程设计中常见的蝶形布置油码头进行研究。结合国内外规范要求,采用对比分析法解析码头长度、系缆墩位置和靠船墩位置3个要点。其中,因为船体平直段相对船中的不对称,靠船墩位置是最为重要的设计内容。系缆墩位置不合理,只会影响缆绳受力均匀性和船舶运动量;而靠船墩位置不合理,会导致设计船型范围内的船舶无法安全靠泊。因此,结合某海外5万~30万t油码头,阐述靠船墩位置设计关键点,供港口工程设计人员参考。

Main points of layout design of butterfly oil terminal

This paper discusses the butterfly oil terminal which is popular in port engineering.Combining with relevant domestic and foreign codes,three main points,i.e.terminal length,mooring dolphin location,and breasting dolphin location are researched by comparative analysis.Among them,the location of the breasting dolphin is the most important design issue,due to the asymmetry of the flat body area relative to the amidship.Unreasonable mooring dolphin’s location will only quantitatively affect the uniformity of mooring line tension and vessel movement,while the unreasonable breasting dolphin location will affect the berthing security.Therefore,the key points of breasting dolphin position design are elaborated through an overseas oil terminal of 50,000 to 300,000 DWT for designers’reference.
