Abstract: A drilling conductor supported within a suction anchor is installed by lowering the suction anchor through the top of a frame of a subsea processing unit. The base of the frame defines a landing area for the suction anchor and supports a fixing system for fixing the suction anchor to the frame. When the suction anchor has been embedded into the seabed beneath the processing unit, the frame is fixed to the suction anchor to form a structural unit that includes the conductor, the suction anchor and the frame. Additional equipment such as a blow-out presenter or a Christmas tree is lowered through the top of the frame and onto the conductor that is supported by the embedded suction anchor.

Abstract: A wellhead foundation is for one or more subsea wells. The wellhead foundation has a suction foundation provided with a housing with an open bottom and a top which is closable with a top cover, and one or more pipes being attached to the housing and extending from the top of the housing and at least over a substantial part of the vertical extent of the housing towards or beyond the open bottom of the housing inside or outside of the periphery of the housing, and a straight upper portion of each pipe projecting up above the top of the housing and forming an upper well-pipe portion which forms part of a high-pressure barrier in the well. The straight upper pipe portion of each pipe is arranged parallel to the center axis of the housing. A method of establishing a subsea wellhead foundation is described as well.

Abstract: The invention concerns a method for installing a hatch (34) to a subsea structure (10) by connecting the hatch to the subsea structure by at least one hinge (20) having a first mounting portion (21), a second mounting portion (22), a flexible portion (23) interconnecting the first and second mounting portion allowing a pivot connection between the first and second mounting portion. The installation steps comprise •—inserting a protrusion (23) of the first mounting portion (21) into an installation hole arranged in the subsea structure (10), •—inserting a protrusion (24) of the second mounting portion (22) into an installation hole arranged in the hatch (34), thereby •—engaging the first mounting portion (21) of the hinge (20) for anchorage with the subsea structure (10) and engaging the second mounting portion (22) for anchorage with the hatch (34) thereby arranging for the hatch to pivot between a closed and an open position about a pivot axis provided by the flexible portion of the hinge. The invention also concerns a hinge and an assembly for subsea use.

Abstract: The present disclosure relates to subsea tool apparatus and methods, particularly but not exclusively tool apparatus and methods relating to subsea trees or so-called “Christmas trees”. The subsea tool is for reinstating the functionality of a subsea tree valve actuator, by applying a thrust force to the subsea tree valve actuator stem, characterised in that: the tool gets its power supply to provide load on the actuator stem, directly or indirectly from the subsea tree SCM (subsea control module) supply.

Abstract: A system is for establishing a collection of well foundations, the well foundations being formed of suction-foundation units arranged to be driven down into an unconsolidated mass. An alignment template includes several through cut-outs, each arranged to receive a suction-foundation unit. The alignment template placed over the unconsolidated mass, forms a means of positioning the suction-foundation units before the suction-foundation units are driven down into the unconsolidated mass. A method of establishing a collection of well foundations is described as well.
