Abstract: An offshore drilling vessel includes a floating hull subjected to heave motion. The hull includes a moonpool and a drilling tower near the moonpool. A drilling tubulars storage rack is provided for storage of drilling tubulars. The vessel includes a heave motion compensation support that is adapted to support a slip device whilst performing heave compensation motion relative to the heaving motion of the vessel. A racking device is provided with a heave motion synchronization system that is adapted to bring a tubular retrieved from the storage rack in heave motion into a vertical motion that is synchronous with the heave compensation motion of the string slip device. The racking device includes vertical rails and at least two separate motion arm assemblies mounted on said vertical rails. Each separate motion arm assembly includes its own vertical drive which is electrically connected to the heave motion synchronization system.

Abstract: A marine vessel and a method of operation of such a marine vessel include a crane with a boom including a main boom section and a jib section and a variable length stay mechanism. The lattice boom is movable from a hoisting position into a parking position by a routine including operating the variable length stay mechanism allowing the jib section to fold towards the main boom section. The crane is provided with a fixation device adapted to establish fixation of the jib section relative to the main boom section in a folded position. A boom rest is mounted on the hull. The routine further includes operating the luffing assembly to position the jib member of the folded jib section, fixated to the main boom section, in the parking position onto the boom rest.

Abstract: A vessel adapted to perform subsea wellbore related operations involving a riser string that is assembled from releasably interconnected riser sections and extends between a subsea wellbore and the vessel. The riser string vertical handling system of the vessel comprises a controlled motion device that is adapted to displace the riser string lifting tool in at least one horizontal direction relative to the riser spider device at least whilst travelling between said elevated and lowered position thereof loaded by the riser string suspended from the riser string lifting tool, thereby allowing to establish an inclined travel path with selectively variable inclination of the riser string lifting tool relative to an imaginary vertical line through the riser string passage of the riser spider device, e.g. said inclined travel path having an inclination selected to correspond to an actual water current induced inclination of an upper portion of the riser string during the riser string assembly process.

Abstract: A vessel adapted to perform subsea wellbore related operations involving a riser string between the subsea wellbore and the vessel. The vessel includes a hull having a deck, and a riser storage hold present within said hull below said deck. The riser storage hold comprising storage racks adapted to store therein parallel stacks of multiple riser sections and/or pre-assembled riser stands in a horizontal orientation. The vessel has an elongated riser transfer opening between said deck and said roof, and the riser transfer opening extending in a direction parallel to said storage racks. The vessel has horizontal rails extending along said opposite longitudinal sides of said riser transfer opening and a catwalk machine having a mobile catwalk machine frame that is movable over said horizontal rails. The catwalk machine is at least in a loading position that is above said riser transfer opening and in a riser upending position.

Abstract: The present invention relates to a top drive well drilling installation comprising a trolley guided along one or more vertical rails along the drilling tower, which trolley is provided with a support frame supporting the top drive unit and a rotating head-clamp. The rotating headclamp comprises an open-centered rotary body defining a pipe passage; a thrust bearing supporting the rotary body; and multiple mobile pipe retainers supported by the rotary body providing an operative and a non-operative position allowing passage of a pipe and engagement below a shoulder of a pipe of the drill string so as to suspend said drill string therefrom. At least the tubular stem is vertically movable relative to the rotating headclamp between an upper remote position allowing the engagement of a pipe of the drill string by the rotating headclamp and a lower connection position allowing the attachment of the tubular stem with the pipe.
