    • A clamp connector emergency release tool designed for subsea operations, when normal release of a subsea clamp connector (14) is not possible, is shown and described. The tool is adapted to be handled and operated remotely by a work class ROV tool. The tool includes a clamp connector (14) adapter housing (7) arranged to engage with and connect to the clamp connector (14) body, a rotatable hole saw (11) mounted on the housing (7), a rotary motor (1) in driving connection with the hole saw (11) and a piston (3) and cylinder assembly (4,5). The piston (3) and cylinder assembly (4,5) enables advancing the rotatable hole saw (11) into the clamp connector (14) body around its jack screw, in order to separate the jack screw together with a threaded portion of said clam connector (14) in order to separate the jack screw from the clamp connector (14) body.
    • 示出并描述了当海底夹具连接器(14)的正常释放是不可能的时,设计用于海底操作的夹紧连接器紧急释放工具。 该工具适用于通过工作级ROV工具远程处理和操作。 该工具包括一个夹紧连接器(14),适配器壳体(7)被布置成与夹紧连接器(14)主体啮合并连接到其上,一个安装在壳体(7)上的可转动孔锯(11),一个旋转马达(1) 与孔锯(11)和活塞(3)和气缸组件(4,5)的驱动连接。 活塞(3)和气缸组件(4,5)能够将可旋转孔锯(11)推进夹紧连接器(14)本体围绕其千斤顶螺钉,以将千斤顶螺纹与所述蛤蜊的螺纹部分分开 连接器(14),以将千斤顶螺钉与夹紧连接器(14)主体分开。
