Fugro provides Technip with real-time wave data for Alvheim subsea tiebacks

Offshore staff

WALLINGFORD, UK – Fugro is providing wave measurements to support construction operations at an improved oil recovery project on the Norwegian continental shelf, around 225 km (140 mi) west of Stavanger.

The subsea infrastructure on the Det norske oljeselskap-operated Alvheim field is being extended by Technip and involves four areas that are being tied-in via subsea wells to improve oil production rates. Technip’s subsea operations – the installation and tie-in of spools and protection covers, along with a manifold – are being performed at depths of around 120 to 130 m (394 to 427 ft).

Technip wanted real-time wave measurements to estimate the sea state, and commissioned Fugro to deploy a Datawell Waverider buoy to monitor wave conditions onsite in real-time over a year.

The Waverider is in place and is collecting a range of raw wave data, processing the information, and then transmitting summary wave parameters at half-hourly intervals via satellite link. Data including wave period, height, and direction are then displayed on a project-specific Web page.
