Abstract: This invention relates to a system for loading or unloading a ship at sea, in particular for operations in connection with oil and gas activity, whereby the ship concerned is equipped with a mooring device at its bow. There is included an anchor device located at the seabed, and at least one anchoring line adapted to connect the anchor device to the mooring device on the ship. A permanent anchor device is provided with a swivel device for the anchoring line, and a buoyant body is attached to a middle portion of the anchoring line. Moreover, there is provided a hose connected to the swivel device and to the ship, for loading or unloading operations.

Abstract: A method of loading and treatment of a gaseous or liquid hydrocarbon mixture produced on an offshore production platform, a production vessel or a well installation when producing oil and gas from a reservoir, wherein the mixture is supplied to a gas treatment vessel (12) via a buoy loading system comprising a buoy (14) of the STL/STP type, and is treated on board the vessel (12) for producing liquefied natural gas (LNG) or an LPG mixture stored in tanks on the vessel. Simultaneously with the supply of the hydrocarbon mixture, oil is also supplied to the vessel (12) via the same buoy (14), the buoy including a multi-course STP connector, the oil being transferred directly from the STP connector via a pipeline (23) and an unloading means (25) on the vessel (12) to a tanker (13) for storage and transport of the supplied oil.

Abstract: A vessel for use in offshore production or transport of hydrocarbons, and/or for loading/unloading of hydrocarbons, and/or for carrying out well operations. The vessel at its forward end is equipped with a submerged receiving space for receiving a bottom-anchored underwater buoy. A service shaft extends between the receiving space and the deck of the vessel. At the stern of the vessel, a coupling head is provided along with equipment for the connection of a hose for loading and unloading of oil.
