Abstract

The invention relates to a crane (1) for an unmanned platform (100) comprising a vertical main mast (2) for connection with the platform (100) and a cantilevered swiveling crane boom (3) configured to perform lifting operations. The crane (1) further comprises a strut (4) having a fixed length, said strut (4) having a first end (4a) pivotable connected to said main mast (2) and a second end (4b) slidingly connected to the crane boom (3), said crane (1) further comprises a lifting arrangement (20) and an electrically driven device (12, 53, 72) adapted to impose a force on the second end of the strut (4b) to move the second end (4b) back and forth along the longitudinal direction of the crane boom (3) between defined end positions (13a, 13b) arranged on the crane boom, the crane (1) further comprising a sliding mechanism (5) having a glide path (13, 51, 71) formed along the longitudinal axis of the crane boom (3) and a yoke (7, 52, 72) pivotable connected to the second end of the strut (4b), said yoke (7, 52, 72) is adapted to move along the glide path (13, 51, 71).

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 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 mobile drilling system comprising a top member with a drilling rig positioned thereon. The top member is removably engaged with a foundation member. The foundation member comprises a tower. The top member is moveable and adapted to be elevated out of the water for placement on top of the tower. The tower is preferably of concrete and extends out of the water and above any ice. A method is also described by which the top member is elevated out of the water either by jacking down legs or lifting by interaction with the tower.
