Offshore oil and gas industry marine contractor Heerema’s Sleipnir has installed the Tolmount platform in the Southern North Sea.

The Tolmount discovery lies in Block 42/28d of the P1330 license, approximately 40km off the coast of Hull, UK, in a water depth of 51m.

Heerema noted that the project consisted of installing the 2,350 metric tonne jacket and 2,500 metric tonne topside constructed and installed by Rosetti Marino.

Following a 5,390km journey from Rosetti’s yard in Italy’s Ravenna, the jacket and topsides arrived at the Tolmount field.

Operated by Premier Oil, Tolmount field development is ‘on track’ to produce first gas in the second quarter of next year. It will serve as an important energy supplier for the UK.

Heerema Transport and Installation Director Michel Hendriks said: “The close collaboration with Rosetti Marino has been a highlight of the Tolmount project.

“Despite challenges introduced by the ongoing pandemic, we worked together to find creative solutions, which were handled with total professionalism and high regard for safety.”

The project involved over 1,100,000 manhours and was completed within a period of 26 months.

In October last year, Premier Oil discovered new gas at Tolmount East well, 42/28d-14, in P1330, Block 42/28d.
