US Oceaneering International Inc, has announced that a unit of BP has agreed to a two-year extension through January 2019, under the Field Support Vessel Services contract that was entered into with the company for work offshore Angola on Blocks 18 and 31, World Oil reported.

Under this contract term extension, the Ocean Intervention III vessel will remain chartered through April 2017, with five option periods for further extension of one-month each. Additional vessels and services, would be provided during the remaining period of the contract, on an as-needed basis, informed Offshore Post.

The company’s CEO, Kevin McEvoy, said: “we have secured this contract extension with BP. In support of this contract, we are also providing vessel-related subsea services, including remotely operated vehicles, tooling, asset integrity and diving services.”

This comes as Angola took over Nigeria’s spot as the top crude exporter in Africa. Additionally, Egypt Oil&Gas reported late October that Angola had become China’s largest crude supplier for the second time in September, taking the top position from Russia. China had imported 4.19m tons of oil from Angola during September, averaging 1.02mb/d. This was a 45.8%  increase when compared to import volumes for the same period in 2015 .
