Offshore Oil Engineering Company (COOEC) has completed its contracted yard work for QatarEnergy’s Idd El-Shargi North Dome (ISND) expansion after loading out three wellhead platform blocks from its Qingdao facility in China.
The previously reported package is valued at 2.2 billion Qatari riyals ($609 million). It includes three wellhead platforms with a combined weight of about 1,300 tonnes, plus nine offshore pipelines, five umbilical cables and four subsea skids. The scope also covers associated pipelines and umbilicals, underwater skid equipment, and refurbishment of facilities on existing in-service platforms.
COOEC said the completed structures will be shipped to the Persian Gulf for offshore installation and joint commissioning.
The ISND work supports Qatar’s offshore expansion programme alongside activity at the Al Shaheen, Bul Hanine and Maydan Mahzam fields, which underpins plans to sustain and further develop production capacity. Qatar produces slightly above 600,000 barrels per day of oil.
Idd El-Shargi is among Qatar’s largest offshore oilfields and comprises the larger North Dome and the smaller South Dome structures.
For engineering support on the ISND expansion, COOEC appointed Worley in March 2024, following earlier front-end engineering and design work.
Separately, COOEC has been awarded the COMP5 contract for the next phase of QatarEnergy LNG’s North Field Production Sustainability (NFPS) project through a consortium led by Saipem. In a recent stock exchange filing, COOEC said it is awaiting formal signing; its share is estimated at more than $800 million within the overall $4 billion package. The COMP5 scope is estimated at five years and includes two compression complexes, with COOEC responsible for main facility construction and specified design and procurement tasks.
