具有延伸到甲板外面的活动悬臂的海上系统
摘要：
本发明涉及海上系统，所述海上系统包括具有甲板(2)的钻机而且还包括悬臂(4)，所述悬臂(4)安装在甲板上，并至少可在纵向方向上于收缩位置和伸展位置之间活动。上述悬臂具有操作端(4a)和内端(4b)，所述操作端(4a)延伸到甲板外面处于悬臂的伸展位置，而上述内端(4b)与操作端(4a)相对。另外上述悬臂在悬臂的纵向方向上具有一个或多个悬臂支承轨道(10)。系统还包括支承机构(7)，所述支承机构(7)包括轨道接合件(7a)，该轨道接合件(7a)能使悬臂作纵向运动。系统还包括支承轨道延伸部分(6b′)，所述支承轨道延伸部分(6b′)用于每个悬臂支承轨道，能通过与悬臂支承轨道定位一致使悬臂支承轨道在悬臂的内端处延伸，用于增加悬臂支承轨道的长度并由此增加悬臂的纵向可达到范围的目的。
摘要（英）：

This invention relates to an offshore system comprising a rig having a deck (2) and further comprising a cantilever (4), which is mounted on the deck and which is at least moveable in a longitudinal direction of the cantilever between a retracted position and an extended position. Said cantilever has an operational end (4a) which extends beyond the deck in an extended position of the cantilever, and an inner end (4b) opposite the operational end. Furthermore said cantilever has one or more cantilever support rails (10) in the longitudinal direction of the cantilever. The system further comprises support means (7) comprising rail engagement members (7a) which allow longitudinal movement of the cantilever.; The system further comprises a support rail extension part (6b') for each cantileversupport rail, that allows to extend the cantilever support rail at the inner end of the cantilever by being positioned in line with the cantilever support rail, for the purpose of increasing the length of the cantilever support rail and thereby the longitudinal reach of the cantilever.
