An apparatus and methods for installation of an offshore platform for supporting equipment installations is provided. The apparatus includes a vertical compression assembly and a counteracting tensioning tendon system. The vertical compression assembly may comprise multiple compression members, a column truss, or other configurations. The methods of fabrication, load out, and installation provide for cost-effective port and installation vessel requirements.

A method includes providing a lower platform block (300) including a first frame (315), a plurality of docking tubes (305) connected to the first frame, and a plurality of first conductor tubes (310) connected to the first frame. At least a first jacket connector block (400) including a second frame (415) and a plurality of second conductor tubes (405) connected to the second frame is releasably coupled to the lower platform block to align the second conductor tubes with the first conductor tubes. A platform deck block (500) including a third frame (515) defining a deck and a plurality of third conductor tubes (505) connected to the third frame is releasably coupled to the first jacket connector to align the third conductor tubes with the first conductor tubes.

System for transporting an offshore structure, the system comprising: a transport apparatus, in particular a vessel or a vehicle, which is configured to receive an offshore structure and to form a slip joint with a slip joint section of a received offshore structure, wherein the system is configured to enter a releasable state, from a fixing state, wherein, in the releasable state, the slip joint formed by the transport apparatus and the offshore structure is smaller than that force in the fixing state.

A device for levelling an offshore foundation construction including a cylinder equipped with a fastening member for removably fastening the cylinder to a part of the offshore foundation construction, a rod mobile in axial translation with respect to the cylinder, the rod including a pushing end so configured to push against a mudmat.

A pile holding system configured to support the pile in an upright position at a pile installation location next to the vessel. The pile holding system includes a pile holder and a pile holder support system. The pile holder support system is configured to be mounted on the deck of the vessel, to moveably support the pile holder, and to move the pile holder in a first direction between an inboard position and an outboard position. The pile holder, when in the outboard position, is located outside the contour of the vessel, for holding the pile in the upright position at the installation location. The pile holder, when in the inboard position with the first and second jaw in the open position, is located within the contour of the vessel.

A method includes mounting a platform deck block to a tower. The platform deck block (500) includes a first frame (515) defining a deck, a plurality of first conductor tubes (505) connected to the first frame, a first plurality of releasable connectors (520) coupled to the first conductor tubes, and a plurality of docking receptacles (800A,800B,800C) defined in the deck. The tower includes a second frame (415), a plurality of second conductor tubes (405) connected to the second frame, and a second plurality of releasable connectors (420) coupled to the second conductor tubes and engaging the first plurality of releasable connectors coupled to the first conductor tubes. The method further comprises mounting a first production block (600) to one of the plurality of docking receptacles.

The purpose of this invention is to provide a method of constructing a building structure inside and above a swimming pool or, man-made lagoon pool to produce the tropical, exotic resort experience of being surrounded by water in a building. This invention is new because of the use of the invention method of constructing over inside and above a pool or man-made lagoon/body of water pool, instead of an ocean, lake, or other natural body of water. The method of constructing in a pool is the innovation.

Described is a vessel and device for upending an elongate element from a deck of the vessel using a lifting means. A number of support structures, mutually coupled and running parallel to each other, for supporting an elongate element in lying position can be displaced collectively, parallel to the deck, relative to the position of the lifting means by displacing means provided for this purpose. A support structure of the device includes an upending tool which is connected for pivoting around an axis running parallel to an edge of the vessel to the relevant support structure and is configured to support an elongate element received in the support structure when this element is upended with the lifting means, wherein the upending tool is rotated around the axis. With the device elongate elements can be moved within reach of a lifting means.

There is disclosed a packer and/or gripper element (10), beneficially for use offshore and/or underwater, the packer and/or gripper (10) comprising an inflatable element or cushion (15a, 15b, 15c, 15d), wherein a periphery of the/each inflatable element or cushion (15a, 15b, 15c, 15d) comprises at least one corner, the at least one corner comprising a concave portion (30a, 30b, 30c, 30d). The disclosed packer and/or gripper element (10) comprises a plurality of inflatable elements (15a, 15b, 15c, 15d), each inflatable element (15a, 15b, 15c, 15d) being communicably coupled to an adjacent inflatable element (15a, 15b, 15c, 15d) by a port (155a, 155b) disposed between the inflatable elements (15a, 15b, 15c, 15d).

A device for levelling an offshore foundation construction including a cylinder equipped with a fastening member for removably fastening the cylinder to a part of the offshore foundation construction, a rod mobile in axial translation with respect to the cylinder, the rod including a pushing end so configured to push against a mudmat.
