美国远洋钻井公司(Transocean DrillingCo.)最近宣布在南朝鲜船厂正在建造一艘Trans-ocean 8号半潜式钻井船和在苏格兰船厂也建造一艘Transworld Rig 74号自升式钻井船。半潜式钻井船上的各种机电操作特性,均能保证在北海恶劣气候环境下和北极海域中钻探。该船有效载重5100吨,水深工作范围从230英尺到2000英尺,最大钻井深度达25000英尺。其外形尺寸:长361英尺,宽240英尺。该钻井船将在1986年7月交货。
Transocean Drilling Co. recently announced the construction of a Trans-ocean 8 semi-submersible drilling rig at a South Korean shipyard and a Transworld Rig 74 jack-up rig at a Scottish shipyard. Various electromechanical operating features on semi-submersible drilling rigs ensure drilling in the North Sea’s harsh climates and Arctic waters. The ship has an effective payload of 5,100 tons with a working depth range of 230 feet to 2,000 feet and a maximum drilling depth of 25,000 feet. Its dimensions: 361 feet long, 240 feet wide. The rig will be delivered in July 1986.
