A foundation interface device for pulling a cable (16) that is arranged in a conduit into a structure. The interface device has a flexible, generally cylindrical pull-in member (12) that is connected to the conduit. At the leading end of the pull-in member is a weak link latch having releasable arms (72) connected to the pull-in member and connection piece (66) connected to the cable. At the rear of the pull in member is a slidable sleeve operably connected to extendable teeth (40). The slidable sleeve has an abutment (36) that contacts an opening of the structure when the interface device is pulled into the opening, causing the sleeve to slide rearward at thus extending the teeth to lock the interface device in the opening.

Provided is a cable hang-off arrangement configured for mounting at the level of an elevated platform of an offshore facility and includes a pipe configured to accommodate a number of protective tubes, wherein a protective tube is configured to accommodate a transmission cable of the offshore facility; a tube end flange arranged around an end portion of each protective tube; and a hang-off terminator configured for mounting at an end of the pipe, which hang-off terminator includes an end-plate with a number of apertures for the transmission cables, and a flange connection interface for connecting to the tube end flanges. An offshore facility, and a method of securing a transmission cable arrangement at the level of an elevated platform of an offshore facility are also provided.

Disclosed is a guiding device for guiding an elongated element such as a cable or a pipe from the exterior into a hollow interior of a support element, the support element being a support element for supporting an offshore structure and being at least partly submerged in water, wherein the guiding device comprises; a tube having a first opening at a first end for facing the exterior and a second opening at a second end opposite to the first end for facing the hollow interior of the support element. The guiding device is configured to allow water to flow into the first opening and out of the second opening of the tube, and substantially prevent water from flowing into the second opening and out of the first opening whereby the guiding device allows water to enter the hollow interior of the support element but not exit the hollow interior.

Provided is a cable hang-off arrangement of an elevated platform including a number of tubular enclosures, wherein a tubular enclosure is configured to accommodate a transmission cable arrangement and includes a vertical section arranged for connection to a supporting structure of the elevated platform; a horizontal section arranged at the level of the elevated platform; and a curved section between the vertical section and the horizontal section. Also provided is a tubular enclosure of such a cable hang-off arrangement; an offshore facility; and a method of securing a transmission cable arrangement to such an offshore facility.

An assembly for installing a subsea cable, the assembly comprising a submersible apparatus and a submersible cable holder comprising the subsea cable, the subsea cable being connectable to the submersible apparatus through the connector for transmission of electric power and/or data to the submersible apparatus; wherein the assembly is configured to install the subsea cable while the submersible apparatus is electrically powered through said subsea cable. And a method for installing a subsea cable with a submersible apparatus, the method comprising: supplying electric power and/or transmitting data through the subsea cable to the submersible apparatus; and laying the subsea cable in a sea with the submersible apparatus.

A method includes mounting a lower platform block (300) to a plurality of piles (215) positioned on a surface. The lower platform block includes a first frame (315), a plurality of docking assemblies (305) connected to the first frame and engaging the piles, and a plurality of conductor tubes (310) connected to the first frame to a plurality of piles. The docking assemblies are released from the piles to separate the lower platform block from the piles.

A pull-in head assembly (8) for releasably connecting a pulling arrangement (112) to an elongate flexible structure (4, 6). The pull-in head assembly (8) comprises a body (30) which defines a pulling axis X of the pull-in head assembly (8) and a retaining member (32) arranged around the pulling axis X. The retaining member (32) is configured to secure the pull-in head assembly (8) to an elongate flexible structure (4, 6) such that, in use, a pulling force exerted on the pull-in head assembly (8) along the pulling axis X is transferred to the elongate flexible structure (4, 6). The retaining member (32) is configured to release the pull-in head assembly (8) from the elongate flexible structure (4, 6) when the pulling force exceeds a predetermined threshold such that the pull-in head assembly (8) can be separated from the elongate flexible structure (4, 6).

A pull-in head assembly (8) for releasably connecting a pulling arrangement (112) to an elongate flexible structure (4, 6). The pull-in head assembly (8) comprises a body (30) which defines a pulling axis X of the pull-in head and a retaining member (32) which is configured to secure the pull-in head assembly (8) to an elongate flexible structure (4, 6) such that a pulling force exerted on the body (30) along the pulling axis X is transferred to the elongate flexible structure (4, 6). The pull-in head assembly (8) is configured such that, in use, the body (30) and the elongate flexible structure (4, 6) are rotatable with respect to each other about the pulling axis X.
