Реферат: 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.
