FPSO Internal Turret Integration

In autumn 2006, Nevesbu designed and engineered the structural integration for an internal turret mooring for Bluewater Energy Services. This ship was designed for the Norwegian Continental Shelf.

Due to a large number of risers, heavy seas and the ship's special design, this will be an exceptionally large turret with a bearing diameter of about 20 metres. The bearings for an internal turret mooring are fitted in a cylindrical turret casing in the ship. The bearings enable the ship to move around the turret. This system is particularly suited to areas with extreme weather conditions. Also, because a large number of product streams can result in a complicated turntable, it is advisable to have this in-board for better accessibility. Nevesbu designed and engineered the cylindrical structure extending from the keel of the vessel to the deck and the integration into the ship structure.
