Heerema was contracted for the transportation and installation of three topsides and three bridges by PTSC M&C Vietnam, who fabricated the structures at its yard in Vung Tau, Vietnam.

Heerema said on Tuesday that its work consisted of installing three topsides weighing between 2000 and 2500 metric tons and three bridges weighing 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.

The Aegir vessel arrived at block 5 of the Al-Shaheen on 19 October and began installing 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 28 October.

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.

Al-Shaheen is Qatar’s largest offshore oil field and one of the largest offshore oil fields in the world.​

Total and Qatar Petroleum took over the operatorship of the giant Al-Shaheen offshore oil field for a period of 25 years, beginning in July 2017.

The concession is operated by the NOC, which was established as a partnership between Total (30 per cent) and Qatar Petroleum (70 per cent).

In related news, an FSO duo operating on the Al-Shaheen field has recently been awarded a ten-year extension.

The extension will see the FSO Asia and FSO Africa operate on the Qatari field until 21 July 2032 and 21 September 2032, respectively.
