Abstract: An offshore structure is separated into an upper structure and a lower structure. Part or whole of the lower structure is kept in an upright standing state in water. The upper structure is moved to above the lower structure kept in the upright standing state. A uniting step includes one or both of raising the lower structure to arrange the lower structure on a lower side of the upper structure and lowering the upper structure to arrange the upper structure on an upper side of the lower structure by submerging part of a carrier vessel on which the upper structure is mounted while being held by a pair of arm-shaped structures of the carrier vessel and integrating the lower structure with the upper structure. In this way, an offshore structure is moored safely at an offshore installation site without using a crane vessel.

Abstract: The present embodiments relate to launch and recovery systems for a remotely operated vehicle. The embodiments eliminate or minimize the need for load lines, and provide virtually unlimited excursion distances for remotely operated vehicles, limited only by the amount of tether available at the launch point. Further, the embodiments allow for extended deployments of ROVs by allowing recharging of a tether climbing component while submerged. The system can include a launch and recovery assembly, a tether climbing component, and a remotely operated vehicle attached to a remotely operated vehicle tether. The launch and recovery assembly deploys the remotely operated vehicle and the tether climbing component overboard, and the remotely operated vehicle is configured for tethered operation while maintaining the tether climbing component at a desired depth.

Abstract: This invention relates to a vessel having an extendable and retractable cursor frame assembly for deploying other vessels into a body of water. The retractable cursor frame assembly on the main vessel may be retracted and secured on a module of the main vessel as the main vessel is in transit. When another vessel is to be deployed into the body of water from the main vessel, the cursor frame assembly is then extended into the body of water to facilitate the launch of the other vessel.

Abstract: Offloading cargo from a cargo vessel and delivering the cargo to a cargo recipient, or loading cargo onto the cargo vessel from a cargo supplier, may be performed using a cargo vessel which is spread moored at sea to a plurality of mooring points for mooring the cargo vessel in a desired orientation. Alternatively, the cargo vessel may be rotatably moored. Tubing may be provided and configured to be connected to the vessel for fluid communication between the vessel and the cargo recipient or the cargo supplier, and may comprise a first portion configured to be connected to the cargo vessel and a second portion configured to be connected to the cargo recipient or the cargo supplier. A semi-submersible unit may be operable to travel across the sea and carry part of the tubing from a stand-by location to a position adjacent to the cargo vessel, so as to allow an end of the first portion of the tubing to be connected the cargo vessel for offloading or loading the cargo. The unit may have at least one lifting and handling device, which when the unit is positioned adjacent to the cargo vessel, may be operable for arranging the end of the first portion of the tubing at or near a manifold on the cargo vessel for connection thereto.

Abstract: A subsea payload such as an AUV (autonomous underwater vehicle) or an AUV garage is lifted from an underwater location by flying a latch unit through the water to the payload. The latch unit carries a lift line toward the payload. The latch unit is then attached to the payload and the payload is lifted using tension applied through the lift line via the latch unit. The latch unit can also be used on a lift line to lower a payload and then to release the payload at an underwater location. The lift line is supported by a heave-compensating winch on a surface vessel that effects z-axis movement of the latch unit. The winch maintains tension on the lift line to prevent the lift line falling on the payload. Movement of the latch unit on x- and y-axes is effected by on-board thrusters.
Abstract translation: 诸如AUV（自主水下航行器）或AUV车库的海底有效载荷通过将闩锁单元通过水飞行到有效载荷而从水下位置提升。 闩锁单元携带提升线朝向有效载荷。 然后将闩锁单元附接到有效载荷上，并且使用经由闩锁单元通过提升线施加的张力提升有效载荷。 闩锁单元也可用于升降线上以降低有效载荷，然后在水下位置释放载荷。 升降线由表面容器上的起重补偿绞盘支撑，从而影响闩锁单元的z轴运动。 绞车在电梯线上保持张力，以防止电梯线落在有效载荷上。 闩锁单元在x轴和y轴上的移动由车载推进器实现。

Abstract: The invention relates to a subsea marine load raising and lowering system (1) for use on a vessel, preferably a vessel for laying an offshore pipeline, which system comprises first and second winches (2, 6) for raising or lowering first and second cable portions (4, 8) connected via an equalizing sheave (11), to the axle (12) of which a load connector (13) is connected. The system comprises operating means to perform synchronous raising or lowering of the cable portions. The system further comprises overload protection systems provided at both winches, and a safety assembly (15) preventing any substantial further movement of the cable portions (4, 8) in case the cable portions do not operate synchronously, comprising a structure (15a) mounted to the axle (12) of the equalizing sheave (11) having passages (15c) for the cable portions and further comprising stops (15b) arranged on each cable portion above and in the vicinity of the structure (15a). The safety assembly is arranged such that one of the stops will abut the structure (15a) upon relative movement of first and second cable portion (4, 8) such that the other cable portion is subjected to an increased tension and the overload protection system of that other cable portion will enter into force.
