摘要： In a vessel for installing a structure onto or into a seabed, multiple actuators comprised by a dynamic positioning system and a structure positioning system may be used for controlling a position and/or orientation of the structure. When two actuators are actuated simultaneously or in rapid succession, instabilities may occur. Furthermore, two actuators may be working in opposite directions or with opposite control goals. To increase stability and/or workability of the vessel's actuators, a supervisory control arrangement is provided to interconnect control systems of different actuators of the vessel, for example the dynamic positioning system and the structure positioning system. Where previously the dynamic positioning system and the structure position system were individually operating system, with the supervisory control arrangement one system can take into account an input and/or output of the other system.

摘要： A device for monitoring deep-sea sediment environment in mining polymetallic nodules is provided. The monitoring system includes: acoustic Doppler flow profilers, a self-potential probe, a turbidity meter and an underwater camera. The invention can realize long-term in-situ observation of sediment disturbance, and can realize the mechanical recovery of probe rod-type equipment without large-scale mechanical devices, thereby reducing the overall weight of the recovery equipment and increasing the probability of successful equipment recovery. Compared with the existing long-term in-situ observation equipment on the seabed, it is more environmentally friendly, efficient, energy-saving and reliable.

摘要： The invention relates to a transport and carrying device (2) for transporting and carrying a watercraft (4). In order to provide a device (2) for a watercraft (4), in particular for a motor-driven watercraft (4), which allows an easy and fast launch of the watercraft (4) even without a special launching device, it is proposed that the device (2) comprises:
two lateral floats (6) spaced at a predetermined distance from each other,
a connecting front element (8), which interconnects the two lateral floats (6) and keeps them at the predetermined distance from each other,
a surface-like support structure (10) attached laterally to the lateral floats (6) and preferably also at the front to the connecting element (8), wherein the support structure (10) has openings through which water can pass,
a receiving area (12) for the watercraft (4), between the lateral floats (6) and the connecting front element (8) and above the surface-like support structure (10), and
lifting elements (14), for attaching the transport and carrying device (2) to an external lifting device (22) and for lifting and lowering the transport and carrying device (2) by means of the lifting device (22).-

摘要： A lift and method for lifting equipment modules, and for providing for sideways loading equipment modules, or cargo containers, onto a mounting surface of a sea vessel, such as a ship or submarine. The lift comprises a frame for supporting the equipment modules or cargo containers, and includes a number of conveying beams for conveying the equipment module or cargo container in a sideways direction in relation to the frame, and means for lifting said conveying beams in a vertical direction. The method includes, providing a lift according to the invention; arranging an equipment module or cargo container onto the lift; maneuvering the lift on a ground surface into a position substantial parallel with the hull of said sea vessel; raising the equipment module or cargo container by the lift in a vertical direction to a specific vertical position in relation to a mission bay in said hull; conveying the equipment module or cargo container sideways into the mission bay, by said conveying beams; connecting the equipment module or cargo container to a number of anchoring points within the mission bay and retracting the conveying beams out of the mission bay.

摘要： An offshore transfer system includes an arm construction with a primary measurement system to measure and compensate for relative movement of an element relative to an external reference when the element is supported by the arm tip, as well as a secondary measurement system to measure and compensate for relative movement of the arm tip relative to the element when the element is put down and no longer supported by the arm tip.

摘要： A lifting element, such as for a vessel or vehicle, comprising a lifting element, such as an oblong element, rotated by a number of electrical motors via a rotatable, such as an eccentric, element. The eccentric element ensures that the lifting element can only be tilted within a predetermined angle area increasing the safety thereof. Multiple electric motors are used where one motor counteracts the other within an angle interval to ensure that the tilting element does not tilt undesirably.

摘要： Providing energy to an energy consuming piece of equipment and/or tool during offshore operations. Use is made of a crane including a substructure, a boom mounted on the substructure, one or more hoist winches and cables, as well as an object suspension device suspended from the boom by the cables. A piece of equipment or tool is suspended from the object suspension device. An energy storage unit is provided on the object suspension device and has an input connector. The boom may be provided with an output connector of an energy charging unit and in a lower supply position of the object suspension device it is disconnected from the input connector of the energy storage unit. The piece of equipment or tool is then run on energy supplied by the energy storage unit. Moving the object suspension device to a charging position thereof by employing the hoist assembly of the crane brings the input connector of the energy storage unit in close proximity of the output connector of the energy charging unit which are then interconnected to charge the energy storage unit from a separate energy source.
