摘要： An offshore drilling system includes a drilling tower, a tubular string hoisting device with a crown block and a travelling block suspended from the crown block in a multiple fall arrangement. A heave compensation system is adapted to provide heave compensation of the travelling block. The heave compensation system includes a hydraulic sheave compensator. The system further includes a mobile working deck which is movable with respect to the drilling tower within a motion range including a heave compensation motion range. The heave compensation system is further adapted to provide heave compensation of the mobile working deck by a hydraulic deck compensator, which is hydraulically connected via a hydraulic conduit to the hydraulic sheave compensator, such that in operation the deck compensator moves synchronously with the sheave compensator of the heave compensation system.

摘要： A vessel is adapted to perform subsea wellbore related operations involving a riser string between the subsea wellbore and the vessel, e.g. drilling and/or wellbore intervention. The vessel includes a hull having a deck, and a riser storage hold present within the hull below the deck. The riser storage hold includes storage racks adapted to store therein parallel stacks of multiple riser sections and/or pre-assembled riser stands in horizontal orientation. The vessel has an elongated riser transfer opening between the deck and the roof, the riser transfer opening extending in a direction parallel to the storage racks, the riser transfer opening having a length and a width so as to allow for transfer of a single riser section or a single riser stand in horizontal orientation via the riser transfer opening out of and into the riser storage hold, wherein the risers' handling system is suitable to work at the same time with two different lengths.

摘要： The invention relates to a tubulars storage device (1) for storing a plurality of tubulars (2a-e), said tubulars storage device comprising spaced apart fingers (3, 4) forming therebetween a slot (5), and a plurality of pivotably mounted latch members (9a-e) arranged at spaced apart locations along the slot (5). A rotary camshaft (11) is provided for pivoting the latch members (9a-e) between a closed position and an opened position. A drive (12) is provided for driving the rotary cam shaft (11) and thus pivot the latches (9a-e), one after the other, from their closed position into their opened position. In a final angular position of the cam shaft, all latch members (9a-e) are retained, preferably by opening cams, in their opened position, and are thus all effectively locked in this position, located out of the path of displacement of tubulars (2a-e), thereby allowing displacement of the tubulars along the slot (5).
