TWMA will process approximately 2,000 metric t of drill cuttings per well under a multi-million-pound UK North Sea contract, with mobilisation scheduled for Q3 2026 and operations starting in Q4 2026.

The Aberdeen-based drilling waste management firm won the award under an existing agreement with a North Sea operator that Oilfield Technology did not name. The scope covers offshore drilling waste management services for a multi-well campaign on the UK Continental Shelf and includes deployment of TWMA's RotoMill thermal desorption technology and associated equipment.

The contract extends a North Sea track record the company puts at more than two decades of continuous activity. TWMA's Aberdeen-based team will deliver the project.

Why does at-source treatment matter?

By treating drilling waste at source rather than shipping cuttings to shore, the RotoMill cuts vessel movements and associated emissions by up to 50% compared with onshore processing, according to the company. Across the project, TWMA expects the approach to significantly reduce vessel traffic and deliver a substantial cut in associated CO2e emissions. The company did not quantify the project-level emissions reduction.

The award comes as the UK North Sea grapples with a difficult investment climate, yet operators continue to sanction drilling campaigns that require specialist waste handling.

What did TWMA executives say?

John Robertson, UK General Manager at TWMA, said: "We've been working in the North Sea for more than two decades and securing new work like this is a strong endorsement of our UK business and our team in Aberdeen. It reflects the confidence operators continue to place in our technology, our people and our ability to deliver safely and efficiently in challenging offshore environments."

CEO Halle Aslaksen added: "The UK Continental Shelf remains an important strategic market for TWMA where we have been delivering drilling waste management solutions for more than two decades. This contract reinforces our long-term commitment to operators in the region, helping them manage their drilling waste more safely, efficiently and sustainably."
