Abstract
Methods and arrangements are provided for release of an ROV operable subsea clamp connector, the clamp connector comprising at least two clamp segments hinged to move pivotally, and a drive screw connecting the clamp segments by threaded engagement with trunnions arranged rotatable in the pivoting ends of the clamp segments, the threads of the drive screw and trunnions turned such that the trunnions travel along the drive screw in mutually opposite directions when the drive screw is turned. An axial bore in the drive screw is adapted for accommodation of a waterjet cutting tool having a sideways pointing nozzle in a forward end, the waterjet cutting tool rotatable inside the bore while feeding high-pressure water through the nozzle, towards the wall of the drive screw until the wall of the drive screw is cut through.
