深海环境大型船舶抛锚定位技术研究与实践
|
摘要
海洋打捞船、潜水作业船、各种非自航挖泥船、钻探船、海洋石油平台、海上桥梁施工起重船等一些大型船舶在进行海上工程作业时,为了在预定位置上作业,需要将船舶定位在一个准确的位置上,作业船舶常通过定位锚泊设备来控制船位,也就是大家所知的船舶抛锚定位技术。本文以援马尔代夫中马友谊大桥项目施工大型船舶抛锚定位为依托,对深海环境中大型工程作业船舶抛锚定位技术进行分析探讨,为海洋环境中大型工程船舶抛锚定位提供技术支撑。
In order to carry out the offshore operation at a predetermined location, some large ships need to be anchored at an accurate position, which include marine salvage ships, diving ships, non-propelled dredgers,drilling ships, offshore oil rigs and offshore bridge-construction pontoon cranes. The ship's position is often controlled with the mooring equipment, which is well-known as the ship anchoring & positioning technology.Based on the anchoring and positioning work of large construction ships in China Aid Sino-Maldives Friendship Bridge project, the above technology is analyzed under the condition of deep sea. The results will technically support the large ships being anchored and positioned in ocean.
