Embodiment Construction

[0031] figure 1 The embodiment is schematically described and shows a subsea workstation 1 for diving operations, which provides the diver with a tool box comprising two or more tools 23 which need to be passed through a supply line 22 To be powered for ease of use. The subsea workstation 1 is connected to the vessel 100 by means of an umbilical 30 and one or more hoisting lines 51 . The umbilical 30 includes two or more main supply lines 31 through which the tools 23 can be powered. The umbilical 30 may further supply power to other equipment on the workstation, such as lights 25 , cameras 26 etc., which may be provided with their own supply lines 27 , 28 extendable through the umbilical 30 .

[0032] The workstation 1 comprises two or more supply line storage units 21, 21', 21", such as figure 1 winches, spools or reels shown in , the corresponding supply lines 22, 22', 22" are stored on these supply line storage units, the supply line storage units 21, 21', 21" are arran...

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'').

Description

technical field [0001] The invention relates to a workstation for transporting and positioning equipment to an underwater position. Background technique [0002] Specific tasks with respect to subsea structures such as pipelines, foundations of platforms, wrecks of ships, etc. are usually performed by sea divers. Divers descend to their working positions in a pressurized diving bell. When deployed, the diving bell is connected to the ship by a main umbilical through which the necessary supplies and other breathing gases, hot water, communication lines and electricity are transported to the bell. The bell is lowered or raised by a hoisting cable. In addition, a guide wire connected to an anchor weight stabilizes the bell at the required depth. [0003] Equipment can be lowered in a separate tool basket. The tool basket is attached to the boat by a hoist rope to lower or raise the tool basket. [0004] Additionally, there may be a remotely operated vehicle (ROV) to suppor...
