Abstract: 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.

Abstract: A creep resistant material comprises a core layer (12) of rigid polyurethane with a first tensile reinforcement layer (17) applied on one surface and a second tensile reinforcement layer (17) applied on the other opposed surface of the core layer, the entire respective first and second tensile reinforcement layers being in contact with the first and second surface of the core layer of the material.

Abstract: An apparatus (1) for restricting the bending of a tubular member underwater comprises a plurality of interlocking modules each formed from a first half shell component (2) circumferentially displaced from a second half-shell component (3), wherein the first half shell component comprises one or more projections (19) extending from a side edge (18) thereof and the second half shell component comprises one or more grooves (21) in a side edge (18) thereof, the projections and grooves being angled to the side edges of the first and second half shell components, the arrangement being such that when assembled together each of the one of more projections of the first half shell component are inter-engaged with a corresponding groove of the second half shell component to secure the two half shells together.

Abstract: 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.

Abstract: A generally cylindrical element 10 that is adapted for immersion in water is described. The generally cylindrical element 10 has an outer surface 11 that is in contact with the water in use. The outer surface 11 has at least two rows of repeating shapes 20, for example hexagons 20, provided on the surface 11, where each row of repeating shapes 20 is separated from the other or the adjacent row(s) by a groove arrangement 30. Each shape 20 within a row is separated from the, or each, adjacent shape 20 by at least one groove 30. This configuration of the surface 11 reduces Vortex Induced Vibration (VIV) and/or drag that may act upon the generally cylindrical element 10 when it is immersed in a body of water.

Abstract: A weak-link latch for releasably pulling a cable (13) arranged in a conduit (14). The weak link latch is releasably connected to the conduit, and securely connected to the cable. A plurality of arms (4,5) extend laterally from a central member (1) arranged to engage the conduit, with at least one of which arms being a rotatable arm (5,19), rotatable about an axle (6) from an extended position in locked engagement with the conduit to a collapsed position disengaged from the conduit. A shear pin (7) is arranged between the rotatable arm (5,19) and the central member (1), the shear pin arranged to prevent rotation of the rotatable arm from the extended position to the collapsed position, said shear pin having a predetermined breaking force, said breaking force being a shear force due to rotational force from the rotatable arm.

Abstract: A foundation interface that avoids the problem of galvanic corrosion. According to one aspect, the invention provides a foundation interface device arranged to engage an opening in the wall of an offshore foundation or structure having walls made of a first metal. The interface device has teeth or arms arranged to engage the inside of the opening. The teeth or arms are provided with galvanic protection means. According to one aspect, the galvanic protection means comprises a non-metallic contact member arranged on the teeth or arms, where the non-metallic member is in contact with the inside of the opening. According to one aspect the non-metallic contact member is made of a ceramic material.

Abstract: A UV-resistant coating composition for protecting polyurethane surfaces, especially in a marine environment above the sea-air interface (so-called “splash zone”), is formed from an amorphous hydrophobic dimer fatty acid-based polyether polyol and an aliphatic isocyanate, such as hexamethylene diisocyanate, and may include a UV blocking agent such as titanium dioxide. The polyol may be modified with a chain extender. The composition provides an elastomeric protective barrier against the deleterious effects of UV exposure, and is useful on polyurethane surfaces on bend stiffeners, buoys etc.
