Global energy services specialist Hydrasun has secured a multi-million-pound contract in the run-up to Christmas, winning a £2.3million award to supply subsea instrumentation for the Mariner field development in the North Sea.
The contract, awarded by a major subsea original equipment manufacturer (OEM), covers the supply of low and high pressure instrumentation tubing and fittings for a spool Christmas tree build programme, with up to 20 trees to be manufactured over a three-year period.
Initial deliveries are scheduled to begin in Q1 2026, with Hydrasun supporting the phased build programme as the project progresses.
The company will supply specialist instrumentation products manufactured from exotic materials, including Super Duplex and 6Mo, designed to withstand the harsh operating conditions associated with subsea developments in the UK Continental Shelf (UKCS).
Hydrasun will work closely with global manufacturing partner Parker Hannifin to plan and schedule deliveries in line with the OEM’s production timetable, ensuring continuity and certainty of supply throughout the programme.
The Mariner development is one of the largest heavy oil projects in the UK North Sea and continues to play a key role in supporting long-term energy security and investment in the basin.
The award marks a strong end to the year for Hydrasun and further underlines its position as a trusted supplier to the subsea sector, delivering technically complex fluid transfer and control solutions for major offshore developments.
Craig Sangster, Chief Operating Officer at Hydrasun, said: “Securing this award is a strong endorsement of Hydrasun’s capability to support complex subsea programmes through close collaboration with our customers and supply chain partners.
