Saudi Aramco has tapped McDermott International Inc. for the engineering, procurement, construction and installation (EPCI) of four jackets and three gas observation platforms offshore Saudi Arabia.

The contract is the third fast-track jacket contract the company has won from Saudi Aramco in the last 18 months, Linh Austin, McDermott’s vice president, Middle East and Caspian, said in a Jan. 4 news release.

The award follows an EPCI contract for 12 jackets in 2015 and another, for which work is currently being carried out, for nine jackets offshore. The latest award, which will be reflected in McDermott’s fourth-quarter 2016 backlog, is expected to be executed through fourth-quarter 2017, the company said.

McDermott said it plans to use its engineering teams in Dubai, UAE; Chennai, India; and Al Khobar, Saudi Arabia with construction taking place at its fabrication facilities in Dubai and Dammam, Saudi Arabia. Vessels from McDermott’s global fleet are scheduled to perform the installation work, according to the release.
