A subsea fluids storage facility comprises a tank for holding and separating fluids which is equipped with ballast capacity and a separable base to be deployed upon the seabed in shallow or deep water, and the storage facility is connectable to a surface production facility, especially a buoy for processing fluids. In deep water the tank is held at a depth above the base for temperature controlled stabilization of produced oil in the tank.

A displacement system for a submersible electrical system such as a tidal turbine system, the displacement system comprising a base for the turbine or related electrical components, a vessel having a buoyant body and at least three rigid legs each displaceable relative to the body between a raised and a lowered position, and in which the base is adapted to be secured to and displaceable by the three legs in order to allow the base to be deployed or retrieved from the seabed using the legs, which legs can also be utilised to raise the body of the vessel out of the water to provide a stable work platform above the deployment site.

A vessel adapted to perform subsea wellbore related operations involving a riser string that is assembled from releasably interconnected riser sections and extends between a subsea wellbore and the vessel. The riser string vertical handling system of the vessel includes a controlled motion device that is adapted to displace the riser string lifting tool in at least one horizontal direction relative to the riser spider device at least whilst travelling between the elevated and lowered position thereof loaded by the riser string suspended from the riser string lifting tool, thereby allowing to establish an inclined travel path with selectively variable inclination of the riser string lifting tool relative to an imaginary vertical line through the riser string passage of the riser spider device, e.g. said inclined travel path having an inclination selected to correspond to an actual water current induced inclination of an upper portion of the riser string during the riser string assembly process.

Techniques and systems to store and deploy a lift frame of an offshore vessel. A device may include a member arm comprising a locking feature configured to couple the member arm to a lift frame of the offshore vessel. The device may also include a base configured to be coupled to a drill floor of the offshore vessel, wherein the base comprises a joint configured to allow for rotation of the member arm and the lift frame from a storage position having a first angle between the member arm and the drill floor and a deployment position having a second angle between the member arm and the drill floor.

Techniques and systems to remove a portion of a drill floor from an offshore vessel. The drill floor may include an immovable section comprising a first portion of a surface area of the drill floor. The drill floor may also include a moveable section comprising a second portion of the surface area of the drill floor. Additionally, the drill floor may include an actuator configured to retract the moveable section from a first position to a second position to remove the second portion of the surface area of the drill floor.

A floating platform for supporting generators of power derived from the wind, the waves and ocean currents, adopting an approximately disc-shaped general configuration with a circular or polygonal perimeter, which optimises its size and therefore minimises substantially its weight and likewise its production costs, as well as other associated complexities; which eliminates the possibility of entering into resonance with the movement of the ocean waves and thus not damaging the equipment installed, not overturning, and not surpassing the maximum list acceptable for wind power generators, nor wave power generators, nor ocean current generators; and which withstands the waves of the greatest size possible, all due to a ratio between its depth or height (13) and the diameter (14) thereof of between 0.06 and 0.35.

The present disclosure relates generally to electromagnetic coupling modules employed along the outer periphery of floating solar collector pods that can be introduced onto the surface of a body of water that operate to automatically connect to one another so that proximate pods form a reversible self-assembled physically and electrically coupled array that operate to harvest incident solar radiation and also operate to reduce the degree of evaporative water loss from that body of water. Electromagnetic coupling modules are disclosed featuring normally open electrical connection elements that permit electronic coupling under magnetic attraction for improved electrical safety. Electromagnetic coupling modules are disclosed that are gimbaled to provide for increase flexibility and interconnectivity under angular displacement, such as when a floating solar pod array is subject to strong current, wind and wave forces.
