Al Shaheen expansion: PTSC lands key Gallaf offshore contract from Qatar's NOC
EPCI-05 package for the last batch of Phase-2 includes two wellhead platforms
PetroVietnam Technical Services Corporation (PTSC) has won an offshore contract from Qatar’s North Oil Company (NOC) for the second phase of its Gallaf project in the Persian Gulf.
PTSC said on Friday that it has signed a contract for a key engineering, procurement, construction and installation contract (Package 5).
NOC — a partnership of state-controlled Qatar Petroleum (QP) and France’s TotalEnergies — is executing the multi-phase project, which aims to maintain output at Al Shaheen, Qatar’s largest offshore oilfield.
“The EPCI-05 package is part of the Gallaf Batch 3 Project including two wellhead platforms with a total weight up to 19,000 tonnes,” PTSC said.
The company said the workscope of Package 5 involves the “detailed design, procurement, construction, pre-commissioning, commissioning, load-out, sea-fastening, transportation and installation, hook-up and offshore commissioning” of the offshore facilities.
All onshore work will be performed at PTSC Mechanical & Construction Co’s fabrication yard in Vung Tau City, southern Vietnam.
Although PTSC did not disclose the value of the contract, one industry source said it could be worth between $300 million and $350 million.
PTSC was associated with the first batch (Phase-2) of Gallaf. In 2018, it landed a contract from NOC, thought to be worth between $300 million and $350 million, for the decks and bridges of three wellhead platforms.
Gallaf phase two is centred on a pair of wellhead platforms and a large new processing platform, as well as subsea flowlines.
Daewoo Shipbuilding & Marine Engineering (DSME) and Subsea 7 last month confirmed key contract awards for the third phase.
DSME said it had won a contract worth 725 billion won (US$630 million) to build a large fixed offshore platform for Al Shaheen.
It is expected to weigh 30,000 tonnes, comprising a deck of 20,000 tonnes and a 10,000-tonne jacket, Upstream understands.
Subsea 7 has won an offshore pipeline contract for Gallaf.
Al Shaheen is a crucial field for the Qatari government because it accounts for about half of the country’s total oil production, which, according to QP’s annual 2019 review, was running at just over 592,000 barrels per day.
The field’s existing facilities include 33 platforms, 300 wells and several production hubs over nine locations.
Located on Block 5 about 80 kilometres offshore, Al Shaheen started production in 1994, with TotalEnergies assuming operatorship in 2017, when production was about 300,000 bpd.
Under a 25-year concession agreement, TotalEnergies holds a 30% stake in NOC, while QP holds a 70% working interest.
