摘要： An artificial cable trench (ACT) includes a body and a trench formed into the body. The trench is configured to hold a cable, umbilical, or similar feature. The ACT may be positioned along a seabed or shoreline to stabilize the cable and thereby prevent movement and eventual damage to the cable. The body of the ACT is shaped to overcome the flow induced loads caused by the relative motion between the cable and the surrounding waves and sea currents as well as providing effective friction/engagement with a contact surface (e.g., a shoreline surface). The ACT may have features that result in self-burying in sand and/or preventing lateral movement.

摘要： A method of installing a subsea cable bundle comprising an umbilical and at least one direct current and fibre optic (DCFO) cable attached to an outside of the umbilical. The method comprises connecting a first end of the cable bundle to a pulling head, lowering the first end of the cable bundle into the se, connecting the pulling head to a winch cable of a winch (the winch may be connected before or after lowering the first end), the winch being located on a platform and the winch cable extending from the platform into the sea through a J-tube, and using the winch to pull the first end of the cable bundle up to the platform through the J-tube. The method further comprises laying the cable bundle on the seafloor, and at a target location, at or close to a subsea structure, detaching the DFCO cable from the umbilical and connecting the DCFO cable and the umbilical at their second ends to the subsea structure.

摘要： A method and apparatus for selectively releasing at least one retaining element during a pull-in process that locates a rigid support body at a predetermined location with respect to an aperture in a wall of a facility are disclosed. The apparatus comprises: a rigid support body comprising a through bore that extends through a length of the support body and through which a flexible elongate member is locatable; at least one latch arm slidable along a respective axis of sliding with respect to the support body; and for each latch arm, an abutment element that moves with the latch arm and is disposed to abut with a portion of a wall of a facility when the support body is located through an aperture in the wall of the facility; wherein the latch arm is disposed to respectively slide in a first direction of motion away from a retaining element supported on the rigid support body when the rigid support body passes through the aperture to thereby release the retaining element from a storage position when the retaining element is within the facility.

摘要： An electric power transmission cable comprises electric power conductors and a plurality of parallel spiralled armouring wires.The electric power transmission cable comprises along its length a first section (I), a second section (III) and a transition section (II). The transition section (II) is provided between the first section (I) and the second section (III). The plurality of parallel spiralled armouring wires in the first section (I) comprises or consists out of first armouring wires (121). The first armouring wires (121) are carbon steel wires comprising a metallic corrosion resistant coating. At least part of the plurality of parallel spiralling armouring wires in the second section (III) comprise austenitic steel wires (123). In the transition section (II), ends of first armouring wires (121) are individually welded to ends of austenitic steel wires (123) of the second section (III). The transition section (II) starts at the first weld (137) between a first armouring wire (121) and an austenitic steel wire (123). The transition section (II) ends at the last weld (130) between a first armouring wire (121) and an austenitic steel wire (123). The transition section (II) is at least 10 meter long.
