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: 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),
