A ship for use in offshore operations, with one or more vertical openings (moonpools) in the hull, wherein the deck and/or hull bottom areas between or substantially between and/or otherwise adjacent the openings, are displaced relative to the rest of the deck and/or hull bottom areas of the ship to a position closer to the ship's transverse neutral axis. The area between the rest of the other deck- and hull bottom areas and substantially the displaced area or areas at the openings in the ship and the rest of the deck- and/or hull bottom areas can be stepped in one or more steps, or be shaped as an approximately linear or arcuate junction.

Ship for offshore operations with vertical openings

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.

Anchor system for the transfer of fluids

System for mooring ships, in particular for operations in connection with oil and gas activity, whereby a ship is equipped with a mooring device at its bow portion. There is included an anchor device located at the seabed, as well as at least one anchoring line adapted to connect the anchor device to the mooring device on the ship. The anchor device is an essentially permanent anchor device, preferably in the form of a suction anchor, gravitation anchor or pile anchor. The anchor device is provided with a swivel device for the anchoring line. A buoyant body is attached to a middle portion of the anchoring line.
