Abstract
In a device for oil production at great depths at sea, production/drilling equipment is provided on a floating structure (2) at the surface of the sea, such as a platform structure or a vessel structure, for instance a ship, which is connected to a flotation unit (5) under water, which is anchored with a tension mooring (4) to the sea floor and with a riser system (6) which extends upwardly to the deck (9) of the structure. The structure (2) is equipped with an open vertical frame construction (8), such as a trusswork projecting downwardly in the water, the lower part of which forms a guide (17) and protection for the flotation unit (5). The rigid risers (4) from the sea bed continue up with the system (6) through the flotation unit (5) and further, enclosed by the frame (8) up to the level of the deck (9) above the water surface, where they are terminated in a Christmas tree device (7), or a manifold. A flexible riser system (11) extends from the valve arrangement (7), e.g. in a pendulous arc to the deck (9), the pipes (11) being dimensioned to permit a maximum height displacement between deck and flotation unit.
