Subsea 7 has snared a pair of contract awards with BP for work on the British operator’s Azeri Central East (ACE) project in the Caspian Sea off Azerbaijan.

The Aberdeen-based contractor will carry out engineering and fabrication of subsea structures, engineering, transport and installation of spools, the launch of a 16,200-tonne jacket and the floatover of an 18,500-tonne topsides for the project, part of the Azeri-Chirag-Gunashli field complex.

The contracts, with a “sizeable” combined value of between $50 million and $150 million, will be executed in a consortium with BOS Shelf, a unit of Azerbaijan’s state-owned oil company Socar.

Subsea 7 will start engineering work immediately at its offices in France, with offshore installation to be carried out in 2021 and 2022.

BP recently handed out five contracts worth more than $1 billion for the $6 billion ACE project that will entail a new platform located between the existing Central and East Azeri facilities to exploit up to 300 million barrels of crude, with start-up scheduled for 2023.
