ABERDEEN, UK – Moorings Systems has completed installation of a flexible export flowline to take water to a DP tanker at BP’s Valhall field complex in the Norwegian North Sea.
The project involved engineering and installation of 1,160 m (3,806 ft) of 6-in. (15-cm) flexible flowline.
Mooring Systems deployed a 150-t spooler for the flowline containing five sections of Manuli hose - three x 300 m (984 ft), 120 m (393 ft) and 140 m (459 ft) - on the DP vessel Olympic Zeus.
The flowline was connected to the Valhall production platform using a specially designed hang-off spool fitted to the end of the hose, and was laid along the sea bed away from the platform.
A 20-in. (51-cm) Pusnes connector was fitted to the end of the hose and set down on the sea bed with a pick-up rope and marker buoys, for subsequent retrieval by DP tanker. The flowline was then leak tested and covered with concrete mud mats.
