Abstract: An unmanned wellhead platform (1) (UWP) comprising a jacket (10) designed and adapted to be supported on the seabed and projecting above the sea level is shown. The unmanned wellhead platform (1) includes a topside installed on top of the jacket (10). The topside is designed as a standardized base concept tailored for repetitive future topside constructions (3). Each topside construction (3) is adapted to the number of wells to be developed. The topside construction (3) is made up by a number of different but standardized sections (4). Each standardized section (4) is dedicated for a particular and predetermined purpose and location in the topside construction (3).

Abstract: An offshore material handling system including an offshore crane carrying vessel(4), an installation structure (1) fixed to the seabed and projecting above the sea level is described. The installation structure(1) includes a material handling distribution system on board the installation structure(1). The material handling system includes an independent platform structure(3) for temporary attachment to the installation structure(1) and temporary use on the installation structure (1) for load transfer.

Abstract: An arrangement of an unmanned and remotely operated production facility comprising a wellhead platform including a wellhead assembly having an X-mas tree, a flowline transporting hydrocarbon fluids produced from a well via said wellhead assembly to one or more consecutive process equipment(s), and further on to a destination via a transport line. Any process equipment and/or pipeline section located at a higher level than said outlet point from said wellhead assembly, is arranged to either drain back to the x-mas tree, or drain downstream to said transport pipeline by assistance of respective valves arranged along said flowline.

Abstract: A deck hoist tractor (DHT) for an unmanned platform (1) comprising an elongated base frame structure (12) carrying respective caterpillar drives (18) on each side enabling the tractor (2) to move forward and rearward, characterised in that the tractor (2) further comprising a tower frame structure (10) extending in substantially vertical direction from one end section of the base frame structure (12), which tower frame structure (10) is carrying a cantilevered top frame structure (11) carrying a lifting apparatus (22, 21), said caterpillar drives (18) are located at the same end section as said top frame structure (11), that said base frame structure (12) is extended by respective cantilevered beams (12a) space apart with an opening between them, each cantilevered beam (12) having an adjustable support structure (19) adjacent to their distal end (12b) from the caterpillar drive (18), said cantilevered top frame structure (11) is extended to vertically correspond with said respective cantilevered beams (12a),

Abstract: An arrangement of an unmanned and remotely operated production facility comprising a wellhead platform including a wellhead assembly (1) having an X-mas tree, a flowline (2) transporting hydrocarbon fluids produced from a well via said wellhead assembly to two or more consecutive process equipment(s) (3-6), and further on to a destination via a transport line (8). Any process equipment and/or pipeline section located at a higher level than said outlet point A from said wellhead assembly (1), is arranged to either drain back to the x-mas tree, or drain downstream to said transport pipeline by assistance of respective valves arranged along said flowline (2).

Abstract: A method and system for oil production in remote deep-water areas, especially in areas where weather or ice conditions may require closing and removal of surface facilities and equipment. Processing of the produced oil from subsea oil wells is partly performed subsea on a subsea oil and gas production unit (10) called Deepwater Production System (DPS), whereas the remaining processing takes part on a vessel (1) that may be disconnected from the DPS if the conditions make it necessary. The method and system take advantage of combining and integrating subsea processing with processing at atmospheric pressure onboard the vessel.
