A dynamic sealing device provides sealing between at least a first part and at least a second part having a relative rotational movement in relation to the first part. The device is formed by a seal including a body portion; a first main lip extending from the body portion; a second main lip extending from the body portion, the first lip facing the second lip; the first and second lips being configured to be energized by a first fluid so as to seal at least one of the first part and second part. The seal further includes at least one additional lip located on the body portion remotely from the first and second lips and being configured to be energized by a second fluid so as to seal at least the other of the first part and second part.

Disclosed is a bearing arrangement for a bearing wheel in a turret, the bearing arrangement being providable between the bearing wheel and a wheel shaft around which the bearing wheel is rotatably connectable. The bearing arrangement includes a slide bearing enabling the bearing wheel to slide axially on the shaft. The bearing arrangement further includes a roller bearing. A plurality of bearing arrangements may form a bearing system that is employed in a turret of a vessel. A method for mounting a bearing arrangement in a bearing system is also disclosed.

A mooring assembly for a vessel comprises a moonpool having a casing, a turret mounted in a moonpool for a rotation by upper and lower bearing assemblies. The lower bearing assembly comprises a stiff inner bearing ring attached to a lower part of the turret, an outer bearing ring attached to a casing of the moonpool and a number of circumferentially spaced bearing blocks positioned between the inner and outer bearing rings. A mounting assembly maintains a substantially fixed position of the bearing blocks relative to the outer bearing ring but allows the bearing blocks to assume a position where the load transfer between the bearing blocks and outer bearing ring occurs with a minimum of stress concentrations within the outer bearing ring and wherein the larger part of the load transfer occurs directly between the bearing blocks and outer bearing ring without being directed through the mounting assembly.

A mooring line (10) comprising a metal chain (24) and an elastomeric element (28) which is attached between two points of attachment (30, 32) thereby defining a bypass section (34) of metal chain (24). The elastomeric element (28) is arranged such that when an initial tensile load is applied, the elastomeric element (28) stretches from an initial length to a longer length wherein the bypass section (34) is not taut and thus the initial tensile load is transmitted from and to further sections (24) of the metal chain through the elastomeric element (28). When a further tensile load is applied, the elastomeric element (28) stretches to a length wherein the bypass section (34) becomes taut, and thus the further tensile load is transmitted directly from and to the further sections (24) of the metal chain through the bypass section (34).

Disclosed is a water intake system for a floating vessel in a body of water, which includes within the hull of the vessel an intake compartment for taking in water from the body of water and a distribution compartment for distributing and supplying the water to one or more consumer units within the floating vessel. The intake compartment is arranged below a lowest operational draught of the vessel and has an inlet in a bottom region of the intake compartment. The intake compartment is coupled by a conduit to the distribution compartment for allowing water to flow into the distribution compartment. The water intake system further includes a water lift hose that is connected to the inlet and is extendible below the hull of the vessel.

A floating hydrocarbon processing/storage structure with a first and second assembly, each including a hull having side walls, one or more storage tanks and a deck structure, a connection structure interconnecting the hulls, processing equipment situated on the deck structures, at least one riser connected to a subsea hydrocarbon well and to the processing equipment and/or storage tanks, with a mooring system connecting the processing/storage structure to the sea bed, each hull including a hull deck structure bridging the side walls, the connection structure including a central deck extending at or near the height of the hull deck structures along at least 70% of the length of the hulls, the central deck supporting at least one of: risers vertically extending from the central deck between the hulls to the sea bed, fluid ducts horizontally supported on the central deck, and at least one drilling/work-over rig or crane.

In an offshore system having a floating vessel, a turret within a hull opening, and a bearing assembly including a support row assembly axially transferring the weight of the turret to the vessel and allowing the vessel to weather vane about the turret, a method and arrangement for in situ remediation of a damaged support row assembly. An outer upper ring is removed from an outer lower ring and a support ring is installed on the outer lower ring. A lower race and support rollers of a remedial support row assembly are installed on the support ring. A reaction ring is positioned above the support ring and connected to an inner ring secured to the turret. The inner ring is axially displaced relative to the outer lower ring and the turret axial loading is transferred to the remedial support row assembly between the support ring and the reaction ring.

A turret mooring and riser hang-off arrangement, for transferring petroleum products from an off-shore or subsea facility to a vessel, including a turret arranged in a cavity of the vessel. The turret is held firmly in axial and radial directions within the cavity, but is rotatable relative to the vessel. The turret is adapted to be moored to the seabed. A riser assembly extends through a bore in the turret to an upper surface of the vessel. The bore of the turret is a monobore and the riser assembly is rotationally coupled to the turret but is free to move axially relative to the turret. The riser assembly is axially supported by the vessel.

This relates to an electrical rotary joint device configured to equip an energy exploitation installation including a first part having an electrical connector and a first electrical track electrically connected to the first connector, a second part having a second electrical connector and a second electrical track electrically connected to the second connector, and an electrical interconnection mechanism configured to electrically interconnect the first and second electrical tracks, with the first part and the second part being movable with respect to each other and defining between them a closed internal chamber in which the first and second electrical tracks and the electrical interconnection mechanism are housed, the latter including electrical contact members that are housed, in particular prestressed, between the first and second electrical tracks and are configured to form rolling deformable contacts between the first and second electrical tracks.

Embodiments relate generally to a turret system for use in a floating vessel. The turret system may comprise a turret body and windlass subsystem. The turret system may comprise top and bottom surfaces, first and second mooring line storage sections, and first and second mooring line channel sections. Each mooring line storage section may include an opening and cavity. Each opening is operable to receive a mooring line. The first and second mooring line channel sections may be separate elongated passageways for first and second mooring lines, respectively, to be directed through the turret body and an exterior of the floating vessel without coming into contact with one another. The windlass subsystem may comprise a rotatable member, and configured to be transportable between locations. When the windlass assembly is configured to be secured to the turret body, the windlass assembly is configurable to control a movement of a mooring line.
