Abstract: An anchoring system for the production of hydrocarbons at sea by employing a moored production vessel or ship in which the ship is equipped with a mooring apparatus, preferably at the bow portion, and with at least one connection unit for a production riser from the seabed. Included is an anchor located at the seabed, as well as at least one anchor line adapted to connect the anchor to the mooring apparatus on the ship. There being provided a permanent anchor, preferably in the form of a suction anchor, gravitation anchor, or pile anchor. The anchor being provided with a swivel mechanism for the anchoring line, preferably with a buoyant body attached at a middle portion of the anchoring line, and whereby the riser is in the form of at least one flexible hose, the lower end of which is connected to said swivel mechanism. The flexible hose contains at least two passages for hydrocarbons and possibly other fluids.
