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 7):
A method according to  claim 1 , wherein the vessel further comprises:\n a moonpool in said hull, a tower arranged at said moonpool, a hoisting device comprising a hanger device that is movable up and down relative to the tower, wherein the riser stand transfer opening is an orientation with a length towards the moonpool, wherein the vessel is further provided with a strongback assembly comprising:\n a strongback having an elongated strongback frame provided with one or more retaining members adapted to retain a single individual riser section or single pre-assembled riser stand relative to the strongback frame, wherein the strongback frame has a leading end and a trailing end, \n wherein the strongback frame is provided with a lifting member at the leading end thereof, and wherein the hanger device of the hoisting device is provided with a lifting member adapted to be connected to the lifting member at the leading end of the strongback frame, wherein the method comprises:\n arranging the strongback frame in a transfer position above the riser transfer opening, the strongback frame in said transfer position thereof being substantially horizontal, \n performing said transfer step by means of said elevator in a manner to bring said single individual riser section or single pre-assembled riser stand to said strongback frame, \n retaining said single individual riser section or single pre-assembled riser stand to said strongback frame on said strongback frame, \n bringing said single individual riser section or single pre-assembled riser stand into a vertical orientation by operating the hoisting device so as to lift the leading end of the strongback frame.
