Vessel hull for use as a hull of a floating hydrocarbon storage and/or processing plant, method for producing such a vessel hull, vessel comprising such a vessel hull, as well method for producing such a vessel having such a vessel hull

A vessel hull for use as a hull for a floating hydrocarbon storage and/or processing plant, comprising:

• a stern portion, a bow portion and a central portion in between the bow and stern portions, the vessel hull provided with longitudinal hull sides comprising the longitudinal hull sides of the stern portion, the bow portion and the central portion,
• a deck, arranged on the hull, suitable for supporting hydrocarbon processing modules,
• hydrocarbon storage tanks, arranged inside the hull, for storing hydrocarbons to be obtained from seabed-based wellheads,
• an anchoring connection arrangement for connection with anchor lines suitable for mooring the vessel hull to a seabed,
• wherein the deck comprises process module reinforcements suitable for supporting hydrocarbon process modules,
• and at least two of the following elements:
• both longitudinal hull sides comprise mooring line connection reinforcements near or in the bow portion and stern portion for connecting mooring lines to be used with a spread-moored anchor line arrangement and one or both longitudinal hull sides comprise riser balcony connection reinforcements arranged in between the mooring line connection reinforcements in longitudinal direction, suitable for supporting a riser balcony for connecting risers,
• the bow portion comprises a turret reinforcement suitable for receiving an internal turret,
• the bow portion comprises a turret reinforcement suitable for receiving an external turret, wherein the turret is provided with anchor line connection points and riser connection points.

A method for producing a vessel for use as a floating hydrocarbon storage and/or processing plant using a vessel hull comprising a stern portion, a bow portion and a central portion in between the bow and stern portions, and provided with longitudinal hull sides of the stern portion, the bow portion and the central portion;

• a deck arranged on the hull, the deck comprising process module reinforcements suitable for supporting hydrocarbon process modules;
• hydrocarbon storage tanks arranged inside the hull;
• an anchoring connection arrangement for connection with anchor lines suitable for mooring the vessel hull to a seabed;
• and further comprising at least two of the following:
• both longitudinal hull sides comprise mooring line connection reinforcements near or in the bow portion and stern portion for connecting mooring lines to be used with a spread-moored anchor line arrangement and one or both longitudinal hull sides comprise riser balcony connection reinforcements arranged in between the mooring line connection reinforcements in longitudinal direction, suitable for supporting a riser balcony for connecting risers,
• the bow portion comprises a turret reinforcement suitable for receiving an internal turret,
• the bow portion comprises a turret reinforcement suitable for receiving an external turret, wherein the turret is provided with anchor line connection points and riser connection points,
• the method comprising the steps of:
• arranging the hydrocarbon process modules on the deck, at the location of the process module reinforcements,
• selecting a desired riser and anchor line arrangement, and
• configuring the vessel hull for use with the desired anchor line and riser arrangement.
