Abstract: The invention relates to a workstation (1) for transporting equipment to an underwater position. The workstation (1) comprises a tool (23) and a supply line (22) in order to power the tool (23). The workstation (1) comprises a winch (21) for storing at least part of the supply line (22). The workstation (1) may comprise two or more tools (23, 23?, 23?) and associated supply lines (22, 22?, 22?) in order to power the respective tools (23, 23?, 23?). The workstation (1) comprises two or more winches (21, 21?, 21?) for storing the different supply lines (22, 22?, 22?).A single umbilical combines two or more main supply lines (31, 31?, 31?) associated with the respective supply lines (22, 22?, 22?) stored on the different winches (21, 21?, 21?).

Abstract: A vessel (10) includes a crane (12) for positioning diver transfer equipment (36) and/or diver equipment (38) overboard the vessel (10) into a body of water (2). The crane (12) includes: a crane base (24) connected to the vessel (10); a crane arm (14) with a suspension point (16) that is movably connected to the crane base (24); and control elements (26) for controlling the crane arm (14) configuration. The control elements (26) are configured for: determining a change in position and/or orientation of the crane (12) resulting from vessel motion, and dynamically adjusting the crane arm configuration to change the position of the suspension point (16) with respect to the crane base (24) so as to at least partially compensate for the change in position and/or orientation of the crane (12).
