Decommissioning of one of the largest UK southern North Sea gas fields has reached a new milestone
Removing and transporting structures from the Hewett gas field in the UK southern North Sea has reached the halfway point in a multi-year project.
Offshore contractor Scaldis SMC has removed three platforms from the abandoned field in block 48/29 and delivered them to a recycling yard in the Netherlands. It has another three to complete, scheduled for 2026, for the full abandonment of the Hewett field.
Scaldis successfully delivered the 48/29C jacket from the Hewett field to the quayside in Vlissingen at the start of October after its removal in September by a heavy-lift vessel.
Gulliver lifted the topsides from the 48/29B and 48/29C platforms and returned to lift the 12-piled 48/29B jacket and 48/29C jacket in a Q3 2025 campaign, transporting them to Vlissingen.
“With the safe removal and transport of this structure, the project has now reached its halfway point,” said Scaldis in a social media post. “To date, three abandoned platforms have been dismantled and removed. The remaining three platforms, forming together the central complex, are scheduled for removal next year, bringing the project to full completion.”
Eni’s Hewett decommissioning programme is an engineering, preparation, removal and disposal contract.
Heavy- lift vessel Gulliver will soon set course for the Baltic Sea to execute two additional projects before the end of Q4 2025.
In Q2 and Q3 2025, Scaldis vessels installed platforms for offshore windfarms in the North Sea.
The steel jacket and topsides for the Thor offshore windfarm, located in the Danish sector of the North Sea off the west coast of Jutland, were installed under a subcontract from HSM Offshore Energy in August.
Scaldis also worked with DEME to install the offshore substation for the Treport windfarm, off Dieppe, France.
