Neptune Energy has awarded Maersk Supply Service (MSS) a contract for subsea decommissioning at its Juliet field in the southern North Sea.
Neptune said MSS would be deploying innovative technology to reduce the time and costs associated with subsea infrastructure removal.
Piping spools and umbilicals will be removed using the Utility ROV Services system (UTROV), a remotely operated tool carrier equipped with multiple attachments for the recovery of subsea equipment.
Use of UTROV reduces the need for multiple vessels and equipment providers to carry out the complex work.
The UTROV system was previously used for work on the Juliet field in 2019 and will be deployed from the Maersk Forza Subsea Support Vessel.
MSS will carry out the scope of work in early 2022, Neptune said.
Located around 25 miles off the Yorkshire coast, the field began producing in 2014 and comprises two subsea wells tied back the Perenco-operated Pickerill A platform.
Production ceased in 2017 and formal cessation of production was approved in December 2018 by the Oil and Gas Authority (OGA).
Decommissioning work began in mid-2019 with the removal of a 190-tonne subsea manifold.
Neptune Energy’s UK managing director, Alexandra Thomas, said work at the field was “progressing well” and that MSS’ scope would conclude work on pipeline infrastructure, enabling the company to move forward with plugging and abandonment operations.
”The use of such innovative technologies is enabling operators to reduce the time, costs and environmental impacts associated with such operations, and ensures the safe and efficient removal of decommissioned subsea infrastructure.”
Maersk Supply Service’s head of integrated solutions, Olivier Trouvé, said: “We are looking forward to mobilising our engineering capabilities and specialised assets to provide safe and efficient operations.”
Last year the company secured a similar contract for the removal of the Dunlin Alpha platform subsea conductors and guide frames, by Fairfield Betula Limited.
