Clamping device and method for providing an electrical connection between a subsea pipeline and an electrical conductor

Abstract

A clamping device (40) for providing an electrical connection between a subsea pipeline (1) and an electrical conductor (31). The device has a clamp element (41) comprising a first leg (41a) having a first leg end (41c) and a second leg (41b) having a second leg end (41d). The legs (41a, 41b) are configured to be provided on respective sides of the pipeline (1). The clamping device has a releasable tensioning device (48) connected to one of the legs (41a, 41b). The clamping device (40) has a first state, in which the ends (41c, 41d) of the first and second legs (41a, 41b) are provided at a first distance (d1) away from each other. The clamping device (40) has a second state, in which the tensioning device (48) is tensioned, causing the ends (41c, 41d) of the first and second legs (41a, 41b) to be at a second distance (d2) away from each other, the second distance (d2) being larger than the first distance (d1). The clamping device (40) has a template hole (42) provided in one of the legs (41a, 41b). The clamping device (40) comprises a connector member (44) provided in the template hole (42). The connector member (44) is mechanically connected to the clamp element (41). The clamping device (40) has a third state, in which the tensioning device (48) is released, causing the connector member (44) to be pressed towards the pipeline (1).
