<p>System of a hydrocarbon transfer buoy and a vessel, the buoy having a length of at least 50 m and a length-to-width ratio of at least 10:1, and including a submerged buoyancy member having a length of at least 30 m and being situated at a depth of at least 10 m below water level, another support frame protecting above water level being connected to the top of the buoyancy member and carrying a support deck and a mooring buoy connector for attaching to a mooring arm connector of the vessel, which mooring arm connector is situated on an arm projecting outboard from the vessel's hull, the buoy being anchored to the sea bed via anchor lines which extend at an angle to a vertical direction, at least one hydrocarbon riser being attached to the buoy. The buoyancy member being connected to the sea bed via at least one substantially vertical taut tendon. The riser has a length of at least 500 m, and includes a steel riser part attached to the buoy, the riser extending up to the mooring buoy connector and being closable by a valve, the riser at its end including a connecting member for releasably attaching to a duct on the mooring arm connector.</p> |
