The invention relates to a mooring buoy (), comprising a submerged part () and a part extending above water level (). The part above water level comprising a fluid outlet duct () for attaching to a vessel (), the buoy being anchored to the seabed via substantially taut anchor legs (). A substantially horizontally oriented fluid transfer duct () being attached to a connector () of the buoy in a non-rigid manner. The buoy comprises a substantially vertical fluid duct () between the connector () and the outlet duct () and a mooring connector () for attaching to a mooring line () of the vessel, wherein the length (L) of the buoy is between 20 m and 70 m and the ratio of the diameter (D) of the lower part () of the buoy and the length (L) being below 0.3, preferably below 0.2.

Wave motion absorbing offloading system comprising a slender mooring buoy

A vessel comprising at least one anchor line (15). Disconnect elements are attached to the anchor line for releasing the vessel from the sea bed. A first part of the disconnect element (16) is directly attached to the vessel and a second part is attached to the anchor line (17). Upon detaching the anchor lines from the vessel, no cables will protrude from underneath the vessel after disconnecting. Thereby the risk of interference of the anchor lines with the vessel itself, with other vessels or with objects on the seabed in shallow waters is avoided. Furthermore, the disconnect elements can be directly controlled from the vessel. Inspection and maintenance can be easily performed. Preferably, the vessel comprises two or more anchor lines, each anchor line having a disconnect element which can be independently operated. Thereby a staged release of the anchor lines is possible which may be adapted to weather conditions or approaching objects such as icebergs.

Vessel having quick disconnect means, and disconnect means for use in

The invention relates to a vessel which is attached to the sea floor by at least one anchor line. A riser support buoy (9) is releasably connected to the vessel. The anchor line or anchor lines are attached to the vessel outside the area of the riser support buoy (9) such that the buoy can be detached from the vessel independently from the attachment of the anchor lines. By releasing the riser support buoy while maintaining the anchor lines in place, the buoy can be released by maintenance purposes, inspection of the buoy body or the riser without the vessel going adrift. Also the forces between the vessel and the buoy are reduced as the anchor lines are not attached to the riser supporting buoy. The riser supporting buoy may be provided with stabilisation lines (45,45') which on one end comprise a ballast weight (46,46').
