Abstract: A work platform (10) for performing a cable operation on a cable on a vessel having a vessel deck (7) has chutes (19a, 19b) for guiding the cable from the sea and onto the work platform (10), an overboarding system (18) and a number of modules (11, 12, 13, 14, 15). Each module (11, 12, 13, 14, 15) has a deck section and a support structure for supporting the deck section at a distance above the vessel deck (7). Each module (11, 12, 13, 14, 15) is configured to be lifted separately onto and away from the vessel deck (7). The deck sections of the modules together form a mezzanine deck on which the cable operation is performed. The overboarding system (18) is secured to the mezzanine deck. At least some of the equipment for performing the cable operation is stored below the mezzanine deck.

Abstract: A cable handling bow (2) for an overboarding system of a work platform has a cable retaining structure (4) for retaining a length of a cable, where the cable retaining structure (4) extends along a partially curved path (6). The path (6) has a first end (8) and an opposed second end (10), where the path (6) has a first straight segment (14) located between the first end (8) and the second end (10) and is spaced away from both ends (8, 10), such that a cable joint connecting two ends of a cable is placeable in the first straight segment (14), when the cable length is retained in the cable retaining structure (4).

Abstract: A safety device and method for protection of the integrity of well barrier(s) or other interfacing structure(s) at an end of a riser string or a hose includes a releasable connection in the riser string or hose, the releasable connection arranged to release or disconnect during given predefined conditions in order to protect the well barrier(s) or other interfacing structure(s). The safety device safety device includes at least one sensor to monitor at least one of tension loads, bending loads, internal pressure loads and temperature. The sensor provides measured data relating to at least one of tension loads, bending loads, internal pressure loads and temperature. An electronic processing unit receives and interprets the measured data from the sensor. An electronic, hydraulic or mechanical actuator or switch is arranged to receive a signal from the electronic processing unit and initiate a release or disconnect of the releasable connection.

Abstract: A method and a safety device are disclosed for protection of well barrier(s) against excessive bending moments from a riser. The safety device is arranged to detect critical bending loads in or in between the well barrier(s) and/or riser, and may include: a device for detecting changes in a curvature between a load carrying riser pipe and an unloaded stiff body attached to or in the vicinity of the riser pipe, said device for detecting changes in the curvature being arranged to measure a relative distance between the load carrying riser pipe and the unloaded stiff body, and a device for triggering disconnection of a releasable riser connector when the distance between the load carrying riser pipe and the unloaded stiff body reaches a predefined critical distance.
