The Al-Shaheen Gallaf 1 project

Heerema’s scope was to transport and install the North Oil Company’s Al-Shaheen Gallaf three topsides and three bridges on behalf of EPIC contractor PTSC M&C Vietnam.

The Al-Shaheen oil field is Qatar’s largest and has a water depth of 60 meters 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.

Installation by Aegir

Aegir arrived at Block 5 of the Al-Shaheen Field on October 19 and started with the installation of the DC bridge and topside. After that, the EG bridge and topside followed, and finally the project was completed with the FC bridge and topside on October 28. The three topsides weighed between 2000 and 2500 metric tons and the three bridges weighed between 700-1100 metric tons. These were installed onto pre-installed jackets in the Al-Shaheen field located around 80 km north of Ras Laffan, Qatar.

Despite scheduling challenges introduced by the Covid-19 pandemic the close collaboration between Heerema, client PTSC M&C Vietnam, and company North Oil Company resulted in a successful project execution that was on schedule and with zero recordable HSE cases.
