Abstract:
A method for assembly of a riser string onboard a vessel that is adapted to perform subsea wellbore related operations involving said riser string, said riser string being configured to extend between a subsea wellbore and the vessel in a wellbore related operation, wherein the vessel including a hull, a riser storage adapted to store therein, in horizontal orientation, multiple pre-assembled riser stands and/or multiple individual riser stand, a deck structure having an elongated transfer opening above said riser storage, a transfer elevator, wherein multiple pre-assembled riser stands, each being pre-assembled from multiple riser sections connected end-to-end and each having a length of at least 150 ft. (45.72 m), and/or multiple individual riser sections each having a length of at least 150 ft. (45.72 m), are stored, in said horizontal orientation, in the riser storage, wherein the method comprises a riser transfer step wherein the transfer elevator is operated so as to raise a single one of said pre-assembled riser stands and/or individual riser sections in the horizontal position thereof from the riser storage, through the transfer opening, to a position above the deck structure.

Claim (Index 2):
A method according to  claim 1 , wherein the vessel further comprises:\n a moonpool in said hull, a tower arranged at said moonpool, a riser handling capacity hoisting device having a riser string lifting tool, which riser handling capacity hoisting device is adapted to raise and lower a riser string relative to said tower, a riser handling system, said riser handling system comprising a catwalk machine, wherein the catwalk machine comprises:\n a pair of horizontal catwalk machine rails, \n an elongated catwalk machine frame having a rear end, a front end, wherein the catwalk machine frame is movable over the catwalk machine rails at least in a rearward loading position and a forward release position, \n a skate supported by the catwalk machine frame and movable by a drive motor along the frame between a rearward skate position and a forward skate position, wherein the skate comprises a riser end support, \n wherein the riser handling system further comprises a riser forward section auxiliary support device, which riser forward section auxiliary support device is arranged at a location along the catwalk machine rails between the moonpool and the catwalk machine frame, when in the rearward loading position thereof, which riser forward section auxiliary support device is movable between an operative position and a retracted position, wherein the method comprises, following said riser transfer step, the steps of:\n arranging the catwalk machine frame in the rearward loading position thereof, \n arranging the riser forward section auxiliary support device in the operative position thereof, \n loading said single individual riser section or single pre-assembled riser stand in the horizontal position thereof onto the catwalk machine and onto the riser forward section auxiliary support device so that a rear end portion rests on the skate in the rearward skate position thereof and so that a forward portion extends beyond the front end of the catwalk machine frame and rests on the riser forward section auxiliary support device, \n advancing the catwalk machine frame along the catwalk machine rails towards the auxiliary support device with the single individual riser section or single pre-assembled riser stand maintaining the horizontal orientation thereof and being supported by riser forward section auxiliary support device during said advancing, \n connecting a forward end of the single individual riser section or single pre-assembled riser stand to the riser lifting tool, \n moving the riser forward section auxiliary support device to the retracted position thereof thereby disengaging from the single individual riser section or single pre-assembled riser stand, \n bringing the single individual riser section or single pre-assembled riser stand into a vertical position by lifting the forward end by means of the riser lifting tool and by further advancing the catwalk machine frame towards the forward release position thereof.
