1986年底,在荷兰的北海区域安装了世界上第一座三角架塔式平台。这是经济地开发海上小型油田的另一种方式。这是一座无人操纵的平台,作业水深为30米,其上装有两套井口头,一个应急掩蔽处,一个控制房和直升飞机平台。选用三角架设计的原因是重量轻和节省费用。与常规导管架式平台相比,可节省结构钢材40％,并且还节省了今后的维护保养费用。 At the end of 1986, the world’s first tripod tower platform was installed in the North Sea region of the Netherlands. This is another way to economically develop small offshore fields. This is an unmanned platform with a working depth of 30 meters and equipped with two sets of wellheads, an emergency shelter, a control room and a helicopter platform. The reason for using tripod design is light weight and cost savings. 40% less structural steel than conventional pipe rack platforms, and saves future maintenance costs.
