Subsea 7, Sea Trucks Group Win Ehra North Works

08 February 2013

ExxonMobil has hired Subsea 7 and Sea Trucks Group for umbilicals and flowlines to serve its Ehra North deep-water field development off Nigeria.

The US supermajor’s Nigerian subsidiary Esso Exploration & Production awarded the works to Subsea 7’s Nigerian subsidiary and Sea Trucks Group Nigerian arm West African Ventures.

Subsea 7’s senior vice president in the region Olivier Carre said the award "underlines our ability to leverage local skills and assets when developing technological solutions for deep-water subsea construction”.

All subsea structure fabrication and "significant parts of the design” will be carried out in Nigeria, Subsea 7 said.

The London-based, Olso-listed contractor said its scope of work included engineering, procurement, fabrication and installation of 25 kilometres of flowlines, 15 kilometres of umbilicals, and seventeen rigid jumpers.

The subsea specialist will also make modifications to the field’s floating production, storage and offloading (FPSO) vessel to integrate it with the new subsea facilities.

Engineering is to start immediately on the contract with offshore installation to begin in early 2015, using the Seven Borealis and the Seven Pacific.
