Abu Dhabi’s National Petroleum Construction Company (NPCC) has been awarded a contract by Saudi Aramco to install four offshore platforms off the Gulf coast of Saudi Arabia.

The contract includes the engineering, procurement, fabrication, load-out, transportation, installation, hook-up and pre-commissioning of four wellhead decks, along with subsea pipelines, cables and tie-ins for the Safaniya, Zuluf and Berri oil fields.

The deal is the third contract NPCC has won since entering Saudi Aramco’s Long-Term Agreement (LTA) programme in October 2016. The company was awarded two contracts to install a total of 17 jackets at the Barri and Marjan fields at the end of 2016.

The new contracts are expected to be carried out in 23 months, according to Aqeel Madhi, CEO of NPCC.

Under the LTA programme the state oil and gas producer has awarded an estimated 15 contracts to the five international LTA contractors, which have exclusive rights to bid for tenders related to the kingdom’s offshore fields. The contracts awarded since the start of 2016 are worth more than $5bn.

The LTA deal was initially signed in 2015 with US-based Dynamic Industries, a joint venture of India’s Larsen & Toubro and Singapore-based Emas, US-based McDermott, and Italy’s Saipem. NPCC became the fifth LTA contractor on 13 October 2016.

Aramco is thought to have requested a number of additional companies to submit prequalification documents to be added to the LTA as either main contractors or sub-contractors.
