| 20110192336 | FLOATING UNIT - The present invention relates to a unit adapted to float in a body of water with a sea bed. The unit comprises a station-keeping system comprising a mooring line, the mooring line comprising a connection portion and a tail portion and when the unit is floating. The body of water reaches a still water line of the unit and the connection portion extends from the sea bed to a mooring line handling arrangement of the unit. The arrangement is adapted to actively alter the length of the connection portion. When the mooring line is in a permanent mooring position, at least a portion of the tail portion is located in the body of water. | 08-11-2011 |
| 20110126749 | TANK ARRANGEMENT ADAPTED FOR A SUBMERSIBLE PUMP - The present invention relates to a ballast system for a marine structure. The ballast system comprises a ballast tank which is in fluid communication with a tank arrangement for temporarily holding bilge fluid and/or ballast fluid in a marine structure. The tank arrangement comprises a storage space defined by at least one tank wall, at least one fluid inlet for introducing the bilge fluid and/or ballast fluid in the storage space, and at least one fluid outlet permitting removal of at least parts of the bilge fluid and/or ballast fluid from the storage space. The at least one fluid outlet is at least partly formed by a caisson adapted for receiving a submersible pump at a submersible pump position in the storage space. | 06-02-2011 |
| 20110041753 | Semi-Submersible Platform Body for Supporting Drilling, Storing, Treatment or Production of Hydrocarbons at Sea - The present invention relates to a semi-submersible platform body for supporting drilling, storing, treatment or production of hydrocarbons. The platform body have a cross section with a centre point in a first plane, and is defined by a side wall formed by at least one side wall section, the side wall is arranged around the periphery of an open recess. Each side wall section comprises a first and a second side, an upper and a lower edge, the first and second side of the side wall section defines at least a first side wall thickness. The first side of the side wall section faces away from the open recess and the second side of the side wall section faces towards the open recess. The mentioned open recess has a cross section with a centre point in the first plane. Further is the centre point of the cross section of the open recess displaced a distance in the first plane, from the centre point of the cross section of the platform body. The present invention provides for a flexible and versatile platform body which is disposed of the need for custom applications of heavy equipment or facilities in order to prevent displacement of the centre of buoyancy. | 02-24-2011 |
| 20100296873 | METHOD FOR INSTALLING A TOPSIDE MODULE ON AN OFFSHORE SUPPORT STRUCTURE - Method for installing a topside module on an offshore support structure that in use comprises at least one support leg that extends a height above the water level. The method comprises the steps of supporting said topside module on a barge in a position adjacent to said at least one support leg and de-ballasting the barge to lift the topside module a height above water level. | 11-25-2010 |
| 20100206213 | Method for Constructing a Floating Unit - The present invention relates to a method for constructing a unit adapted to float in a body of water, the method comprising the steps of:

| 20100183455 | Submersible Pump - The present invention relates to a submersible pump and a submersible pump system for pumping liquid to a marine structure, the pump being adapted to be located in a tube. The pump comprises an upper portion and a lower portion. The upper portion is adapted to be connected to means for suspending the pump in the tube. The pump has a vertical direction extending from the lower portion to the upper portion. The pump further comprises an inlet for allowing the liquid into the pump and an outlet for allowing the liquid out of the pump. The pump further comprises a sealing means located downstream of the inlet and the outlet in the vertical direction, the sealing means being adapted to seal against an inner surface of the tube. The invention further relates to an arrangement for hydraulic drive of the submersible pump and to a semi-submersible unit comprising the submersible pump system. | 07-22-2010 |
| 20100180810 | Sea Water System and Floating Vessel Comprising Such System - A sea water system comprises, an inlet conduit assembly, a ballast tank and an overflow arrangement arranged in fluid communication with the inlet conduit assembly. The inlet conduit assembly provides a fluid communication between ambient environment and the ballast tank. A first pump assembly is arranged in the inlet conduit assembly for pumping sea water through at least a first conduit portion towards the ballast tank. A second pump assembly is arranged in fluid communication with the ballast tank and is arranged for pumping sea water from the ballast tank through an outlet conduit assembly arranged after the second pump assembly. The second pump assembly and the outlet conduit assembly are separate from the inlet conduit assembly. The sea water system may be arranged on a floating vessel. | 07-22-2010 |
| 20100104452 | PUMP ASSEMBLY - The present embodiments relate to a pump assembly comprising a pump which in turn comprises a low side and a high side. The pump assembly comprises a first inlet conduit in fluid communication with the low side and the pump assembly is adapted to provide a first operation condition in which first operation condition fluid is transported in the first inlet conduit towards the low side at a first flow rate. The pump assembly is further adapted to provide a second operation condition in which second operation condition fluid is transported in the first inlet conduit towards the low side at a second flow rate, wherein the first flow rate is lower than the second flow rate. | 04-29-2010 |
| 20100101655 | BALLAST SYSTEM - The present embodiments relate to ballast systems for marine structures. The ballast system comprises a ballast tank and a pump. The pump comprises a low side and a high side and the ballast system comprises a first inlet conduit assembly adapted to provide a fluid communication between the ballast tank and the low side. The ballast system is adapted to provide a first operating condition in which first operating condition a fluid is pumped from the low side to the high side. | 04-29-2010 |
| 20100098490 | DRAIN PIPE - A marine structure comprising a supporting member that comprises a wall at least partially delimiting said supporting member such that an inner side of said wall is arranged to at least partially delimit an inner volume of said supporting member and an outer side of said wall is arranged to face the ambient environment of said supporting member. The marine structure further comprises a drain pipe adapted to guide fluid from said marine structure to a body of water at least partially surrounding said marine structure. At least a portion of said outer side of said wall partially delimits said drain pipe. | 04-22-2010 |
| 20100003085 | MATING - The present invention relates to a method of constructing a semi-submersible unit comprising a side wall, wherein the method comprises the steps of: placing a hull in a body of water, the hull comprising an opening for receiving an end piece, the end piece constituting at least a portion of the side wall; lowering the hull into the body of water, and connecting a deck structure to the hull to form a semi-submersible unit. | 01-07-2010 |
