Abstract: A method and system for sea-based handling/treatment of fluid hydrocarbons (oil) with associated gas include a first separation step in a high-pressure separator (18) installed on the sea bed, from which is output an oil flow containing an essentially predefined percentage of residual gas. The oil containing residual gas is carried through a riser (22) up to a surface vessel/production ship (12), where it is subjected to a second separation step in a second separator (24) incorporated in a low-pressure surface plant on board the vessel (12), this separated residual gas being used as fuel for direct/indirect generation of electric power for the operation of the underwater and above-water sections of the system. Water and gas produced in the first separation step is returned to a suitable reservoir by the use of a multiphase pump.

Abstract: A method and a system for loading and storage of oil from a production platform on a tanker (FSO vessel) which is equipped with a dynamic positioning system (DP system), the oil being transferred via a loading hose extending between the platform and the tanker. The tanker when required is moved substantially along a circular arc which is predefined in relation to the platform, at the same time as the tanker by means of the DP system when required is turned about a defined point on the tanker, for achieving an optimum power consumption during the loading operation.

Abstract: A system for anchoring of a tanker near an offshore production unit (1) which is anchored by means of a number of anchor lines (2, 14) and associated anchors, and from which a tanker (3) in use of the system is supplied with oil or gas. The system comprises a first and a second pair of bottom-anchored buoys (13 resp. 15) located before or behind the production unit (1), as seen in the prevailing weather direction (W), and at a chosen distance from the production unit (1). The buoys (13) of the first pair are located closer to the production unit (1) than the buoys (15) of the second pair, and the buoys (13 resp. 15) of each pair has a chosen mutual distance transversely to said weather direction (W), so that a tanker (3) may be moored in the region between the buoys (13, 15) with the fore-and-aft direction essentially coinciding with said weather direction (W).

Abstract: A device for installation in a floating vessel which is intended for receiving a buoy or a turret in a submerged receiving space at the bottom of the vessel. The device comprises a tubular body (5) dimensioned for installation in a shaft (2) extending vertically through the hull of the vessel and which, at its lower end, is arranged to receive a module unit (6) provided with a through opening (8) for receiving the buoy/turret. When the module unit (6) is installed in the tubular body (5), the module unit at its lower end forms a seal (37) against the tubular body (5), and at its upper end the module unit (6) is fixed in relation to the tubular body (5) by locking means (40).

Abstract: This invention concerns a unitary system for export of liquid natural gas (LNG) from a floating production vessel (FPSO vessel) (1), with the new and inventive consists of the combination of the following points: an LNG buffer tank in the FPSO vessel, with buffer storage capacity for temporary storage of the continuous produced LNG during an LNG tank vessel's absence, a mooring device arranged for short separation moorage between the FPSO vessel's stem and an LNG tank vessel's bow, a cryogenic transfer device arranged between the FPSO vessel's stem and an LNG tank vessel's bow, comprising a flexible LNG pipe and arranged for consecutive transfer of produced LNG; at least one or several LNG storage tanks in an LNG tank vessel, arranged for continuous filling via the cryogenic transfer device until the desired degree of filling of the LNG tank vessel is achieved.

Abstract: Device for storage or mooring of a loading hose (1), preferably for unloading of petroleum fluids from a vessel (100) at sea, with a floating loading hose (1) with the first end (1a) connected to an after manifold (6) of the vessel (100), with the second, free end (1b) of the loading hose (1) arranged to be caught and connected preferably to a midship manifold (7) of an other vessel (200). (a) A swivel (8) arranged for permanent pivotable connection between the first end (1a) of the loading hose (1) and the after manifold (6). (b) Hoisting appliances (9) with movable catch hooks (14) adapted to the loading hose (1) and arranged with mutual separation along the hull's side (102) forward from the after manifold (6) and arranged for complete or partial elevation of the loading hose (1) from the natural floating position.

Abstract: The invention concerns an arrangement for load transfer between the stern of a first vessel and the bow of a second vessel. Two bow hawsers are arranged to run from each of their anchor points near the sides of the ship at each side of the stern, to the bow, with the hawsers having approximately the same length. A loading hose is arranged to run centrally from the middle point of the stern of the first vessel to the bow of the second vessel.

Abstract: A floating multi-unit structure to be used for various operations offshore, on lakes, rivers, etc. It comprises two types of main units, termed propulsion/support unit and operative unit, respectively. Each such main unit includes at least one functional member. The two main units are adapted to be interconnected through their functional members and functionally integrated in a manner resulting in synergetic effects of the totality of the interconnected units. The propulsion/support unit includes one or more vessels equipped with propulsion machinery and equipment to meet support functions. When the propulsion/support main unit is comprised of several vessels, the individual vessels are functionally integrated in a manner resulting in a synergetic effect providing the propulsion/support main unit with the intended combined properties. The operative main unit includes one or more barge members equipped to perform the intended operations.

Abstract: A system for externally locating a sensor in tissue, comprising an external probe including at least first and second electromagnetic output coils with non-parallel longitudinal axes; and output coil driver for alternately energizing the first and second output coils, for generating a time-varying magnetic field which penetrates the patient's skin; a sensor coil, having a longitudinal axis, for developing an induced electrical voltage in response to the time-varying magnetic field; a distance determinator, responsive to the induced voltage from the sensor coil, for determining from the induced voltage, the distance between the output coils and the sensor coil, independently of the relative angle, in a horizontal plane, between the sensor coil longitudinal axis, and the longitudinal axes of the output coils; and a direction determinator for determining and displaying the direction, in the horizontal plane, in which the sensor coil longitudinal axis is pointing.

Abstract: A system for externally locating the depth and orientation of a catheter in tissue with an external probe which generates a virtual rotating magnetic field. The catheter includes an inductive coil for developing an induced signal in response to the virtual rotating magnetic field. An indicating device such as a light bar display or digital readout indicates the strength of the induced signal for locating, independently of the relative angular orientation of the probe and the catheter, the depth in the tissue of the catheter.
