Oil and gas environmental waste contractor TWMA is to install and operate its offshore waste recycling system on the Stena Spey rig in the UK North Sea, currently contracted to Chevron.

Worth around £1million over an initial six months, the contract awarded by Chevron North Sea Ltd is TWMA’s first with the operator. Chevron has opted to process and recycle drill cuttings on site as a more effective and energy efficient method of waste management. TWMA is the first company in the world to offer this complete waste management capability offshore.

Ronnie Garrick, managing director of TWMA, said: “Using TWMA’s environmentally sensitive TCCRotoMill and CCDS system allows Chevron to contain, reuse and recycle drill cuttings on-site, which increases efficiency and improves environmental performance offshore by removing the need for skip and ship operations and reusing the recovered oil in the drilling fluid.

“We are delighted to be working with Chevron for the first time and look forward to developing a long-term relationship with their environmental team.”

The TWMA TCCRotoMill and its mobile counterpart, the TCCRotoTruck, are thermal cuttings processing units that recycle tens of thousands of drilled cuttings each year by effectively breaking them down into oil, water and solid components for reuse. The technology, recognised by the Department of Energy & Climate Change as ‘best available technology’ for treating drilling wastes, drastically cuts the amount of waste going to landfill resulting in major safety and environmental benefits for operators and clients.
