Saudi Aramco has awarded the US' McDermott a contract for the engineering, procurement, construction and installation (EPCI) of 13 jackets in Aramco’s offshore fields of Zuluf, Marjan, Berri and Abu Safah.

The combined total weight of the structures is about 26,455 short tonnes. McDermott says the deal is a ‘large contract’, which it defines as being between $50m and $250m in value.

This is the fourth project McDermott has been awarded by Saudi Aramco in the last two years, according to a company press release. McDermott is part of the pool of five EPC contractors that Aramco has an existing long-term agreement (LTA), enabling them to bid exclusively for the Saudi state oil giant’s projects.

The latest EPCI contract award will be reflected in McDermott’s first quarter 2018 backlog and work is expected to be carried out through the second half of 2018.

McDermott has said it plans to use its engineering teams in Dubai and Chennai with construction taking place at McDermott's facilities in Dubai and Dammam, Saudi Arabia. Vessels from McDermott's global fleet are scheduled to undertake the installation and completions work.

The latest Aramco contract win for McDermott comes at a time when the Houston-based contractor is working towards integrating with fellow US contractor Chicago Bridge & Iron (CB&I), which McDermott acquired in December last year.
