VESSEL FOR OPERATION IN SUBMARINE WELLS AND WORKING METHOD OF DITA VESSEL.

摘要

vessel for operation in subsea wells and working method of said vessel describes a vessel (1) for operation in subsea wells having a deck (7), a moon pool (11) extending across deck (7) and a balancing unit (19) which is mounted on the deck (7) above the moon pool (11) and is provided with a frame (27) which slides along the deck (7); with a support platform (28) which is movable with respect to the frame (27) in a substantially vertical direction (01) and is suitable for supporting loads; and with a drive assembly (29) that connects the support platform (28) to the frame (27), suitable to be selectively configured to move the support platform (28) in direction (01), in either a balance compensation (caused by both wave motion in water as well as inertial motion and shake due to load shifting), as in an elevator mode.
