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.

Claim (Index 13):
A vessel adapted to perform subsea wellbore related operations involving a riser string that is assembled on board said vessel floating at sea from releasably interconnected riser sections, the riser string extending between a subsea wellbore and said vessel, said vessel comprising:\n a floating hull; a riser storage adapted to store therein multiple risers sections; a moonpool in said hull; a tower arranged at said moonpool and fixed to said hull, a riser string vertical handling system comprising:\n a travelling device that is movable up and down along the tower; \n a riser string lifting tool mounted on said travelling device and adapted to connect to an upper end of a riser section, said riser string lifting tool being embodied to support a weight of a riser string; and \n a hoisting device by which said travelling device and said riser string lifting tool is suspended from the tower and which hoisting device is adapted to move the riser string connected thereto via the riser string lifting tool up and down relative to the tower; \n a riser spider device that is supported above the water in the moonpool and is adapted to temporarily suspend therefrom the riser string into the sea, said riser spider device having a riser string passage therein through which the riser string passes, wherein the riser string is temporarily suspended from the riser spider device and a riser section is connected to the riser string lifting tool and positioned above an upper end of the riser string and then connected thereto, after which the riser spider device is disengaged from the riser string and the riser string is lowered by the riser string vertical handling system, wherein the riser string lifting tool moves from an elevated position to a lowered position thereof allowing the upper end of the riser section to be engaged by the riser spider device, and wherein the vessel comprises a controlled riser spider displacement actuator that is adapted to displace, in at least one horizontal direction, the riser spider device or at least a riser dogs carrying part thereof relative to the hull of the vessel, and thereby relative to the riser string lifting tool at least whilst the riser spider device is disengaged from the riser string and whilst said riser string lifting tool travels between said elevated and lowered position thereof and the riser string is 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.
