Sonardyne works closely with Total on Egina mega-project

Total hopes to seal 25% working interest in the basin.

French oil major Total, operator for the Egina oil field offshore Nigeria, has successfully installed acoustic specialist Sonardyne’s Fusion 6G subsea positioning network to support its development of the $15billion project.

The acoustic technology specified for Egina, which is still ongoing, included a field-wide array of Compatt 6 seabed transponders that were deployed and made ready for work eight days ahead schedule.

Located 150 kilometres off the coast of Nigera, in water depths of up to 1,750 metres, the Egina field covers an area of around 500 square miles.

Infrastructure will include an FPSO, an oil offloading terminal and subsea production systems that will included 52km of oil and water injection flowlines, 12 flexible jumpers, 20 kilometres of gas export pipelines, 80 kilometres of umbilicals, and subsea manifolds.

Production at the field is expected to reach 200,000 barrels per day at its peak.

Fusion 6G is Sonardyne’s sixth generation of Long BaseLine (LBL) acoustic positioning system.

Total chief surveyor Frederic Auger said: “The array installation and subsequent UFR campaign performed at the Egina field, has proven to be an extremely successful demonstration of Fusion’s capabilities.

Off the back of it, we will be using it to support ongoing field construction activities throughout the rest of this year and into the 2016 season.”
