Scaldis reaches first milestone in Hewett field decommissioning project

Scaldis has reached their first milestone in the Hewett field decommissioning project with the removal of the 52/5A accommodation complex.

The removal was performed by Scaldis’ Heavy Lift Vessel (HVL) Rambiz. HVL Gulliver is currently being mobilized for the subsequent removal of the remaining jacket foundation and topside, Scaldis shared on their social media channels.

The Hewett gas field, located 20 km offshore from Bacton, in the Southern North Sea sector of UK, was discovered in 1966, by US-based Philips Petroleum, and was one of the first in the North Sea to be developed. The Hewett field is located in Blocks 48/28a, 48/30a, 48/29a, 52/4a and 52/5a of the UKCS. Its  infrastructure comprises six platforms, 32 platform wells, and a further eight subsea wells tied back to the platforms.

It has been owned by Italian Oil & Gas company Eni since 2008. Eni handed in the decommissioning plan in 2020. Petrofac has always been the Duty Holder and, when ownership passed to Eni in 2008, also became the Pipeline Operator. The company is responsible for the decommissioning of the complex.

In September 2023, Eni has been awarded a Carbon Dioxide Appraisal and Storage Licence (CS Licence) by the North Sea Transition Authority. With a significant total storage capacity of around 300 million tons, the possibility to reuse part of its associated infrastructure, and its proximity to the Bacton industrial cluster, makes Hewett an ideal site to permanently store carbon dioxide from industries in the south-east of England and the Thames estuary area, near London, and to promote blue hydrogen production and distribution in line with the UK’s decarbonisation plans and targets.
