Heerema’s heavy lift vessel Aegir has completed the installation of North Oil Company’s Al-Shaheen Gallaf 1 Project. Heerema was contracted for the transportation and installation of 3 topsides and 3 bridges by PTSC M&C Vietnam, who fabricated the structures at their yard in Vung Tau, Vietnam.

The work consisted of installing 3 topsides weighing between 2000 and 2500 metric tonnes and 3 bridges weighing between 700-1100 metric tonnes. These were installed onto pre-installed jackets in the Al-Shaheen field located around 80 km north of Ras Laffan, Qatar. Aegir arrived at block 5 of the Al-Shaheen on October 19, and began installing the DC bridge and topsides. After that, the EG bridge and topsides followed, and finally the project was completed with the FC bridge and topsides on October 28.

The Al-Shaheen oil field is Qatar’s largest and has a water depth of 60 metres with facilities consisting of 33 platforms and more than 300+ wells. The Al-Shaheen Gallaf 1 scope will support the North Oil Company’s ongoing development of the Al-Shaheen field.

Scheduling challenges

Despite scheduling challenges introduced by the ongoing pandemic the close collaboration between Heerema, PTSC M&C Vietnam, and North Oil Company resulted in a successful project execution that was on schedule and with zero recordable HSE cases.

‘The safe and successful installation of the Al-Shaheen Gallaf 1 project completes around 1.5 years of a close partnership between our client PTSC M&C Vietnam, and operator North Oil Company,’ says Koos-Jan van Brouwershaven, Heerema’s CEO. ‘Together we worked on finding solutions, and there was a common drive to move forward despite the challenges we faced.’

This project is Aegir’s second in Qatar, with the earlier completion of the Qatargas North Field Bravo Living Quarters Expansion project in February. Heerema is committed to a future within the region. Now Aegir will sail to Singapore to receive some upgrades, before moving on to the next project.
