The company won a three-year $160m contract extension for light subsea construction, inspection, repair and maintenance services in the Gulf.
The contract work will commence in the second quarter of 2014 and will run through to the third quarter of 2017.
As part of the contract, Subsea 7 will provide two vessels, including a dedicated vessel on a full-time basis.
The service provider will also carry out project management and engineering support, remotely operated vehicle-based inspection and intervention, as well as some construction work.
Of the two vessels that are set to be chartered on a long-term basis, one is a new-build offshore subsea construction vessel while the other is a lighter construction vessel.
Subsea 7 COO John Evans said: "We are very pleased to have been awarded this important contract extension and to be able to continue growing our valued relationship with BP.
"This award highlights our proven track record for safely delivering successful Life-of-Field operations."
