Abstract: A device for rotating a turntable includes a turret and a turntable bearing The turret is rotatable in a through-going opening or well in the hull of a vessel and has axial and radial bearing assemblies arranged in a polar array about the turret center line. In order to reduce the substantial wear caused by relative movements between the axial wheels of the bearing assembly and the circular rail on the bearing support structure, the axial wheels are conically shaped with a double curved surface rolling on the upward facing edge of the circular rail with a slope aligned with an extension line of the rail substantially intersecting with the shaft center line at the center line of the turret. The radial bearing assembly includes horizontally arranged radial wheels with double curved surfaces. Each wheel rolls on an inward facing edge of the circular rail.

Abstract: Anchoring system to hold a vessel anchored during loading or unloading, which vessel can be connected to or from the anchoring system in a similar way under all operating conditions without adjustments in the anchoring system, which anchoring system is comprising one or more anchors, from each anchor an anchor line is arranged extending upwards through the sea to a subsea buoy with swivel, which buoy has connected thereto and suspended the anchor lines and at least one pipeline for loading or unloading up through the sea, from which subsea buoy at least one line is arranged to a surface buoy, and further, at least one anchoring line and at least one pipeline for loading or unloading, arranged to the vessel either directly from the subsea buoy or via the surface buoy to the vessel, distinguished in that in each anchor line slack is arranged, and on one or more anchor-lines one or more clump weights are arranged, and the buoyancy of the subsea buoy and the buoyancy of the surface buoy is adapted such that by da

Abstract: The invention relates to a process for absorbing vapors and gasses by controlling overpressure in storage tanks during filling, transport and storing of fluids in liquid form. The process includes leading of gas down to the bottom of the tank, where a major part of the gas is absorbed in the tank's own liquid in an absorption device or optionally the liquid is supplied from an external source.

Abstract: Arrangement for mooring, loading and unloading of a vessel, comprising: a stationary inner tower with a lower end fixedly anchored to the seabed, from where the inner tower extends upwards through the sea to an upper end over the sea level, which inner tower at level close to the seabed has through connections for hoses and cables for transfer of load and signals, which hoses and cables are brought further up through the inner tower and out of its upper end; a yoke that in one end is rotatably fastened to the inner tower, wherefrom the yoke extends further outwards to at least one outer ballastable end wherefrom moorings are arranged to keep the vessel anchored, on which vessel devices are provided to connect the vessel with the moorings and said hoses and cables for transfer of load and signals.
