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.

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 pull-in head having a body (30) which defines a pulling axis X of the pull-in head. The body (30) has a front end and a rear end and a bore (48) which extends through the body (30) along the pulling axis X. The bore (48) is configured such that a pulling line (28) can be threaded through the body (30).

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 quick release cable pull-in system for securing a conduit (28) in which is arranged a cable (38) to the mouth of a J-Tube (12) or other opening in a structure. The system includes a collar (30) with a groove (32) attached to the end of the conduit. A rotatable locking arm (20) releasably engages the collar when a tapered nose (34) cone is pulled into the J-Tube. The rotatable locking arm has a shoulder member (44) that is biased downward into the interior of the cylindrical opening. According to one aspect, the shoulder member is downwardly biased by an elastomeric collar (46. According to another aspect, the shoulder member is downwardly biased by a spring, by magnetic forces or other means.

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.
