RAW, a leading specialist in inland oil spill response and remediation, operates worldwide from 16 offices in the UK and Ireland.

Under RSK, the business will operate as RSK Raw Ltd and trade as RSK Raw. Neil Stothert, who has been RAW's managing director for six years and has 25 years' experience in the industry, will continue to manage the company. The business and its 85 employees will become part of RSK's contracting division under the direction of RSK divisional director Claire Knighton.

"RSK Raw shares many of RSK's core values, and its service provision complements ours," said RSK's founder and CEO Alan Ryder. "Like RSK, it is a people-orientated business that focuses on building strong client relationships. Our shared ethos will stand us in good stead. I am looking forward to working with our new colleagues."

Stothert added: "I am delighted that we have joined the RSK group and have the support of extensive environmental services that will enable RSK Raw to thrive. Our services are closely aligned with existing RSK services, so we will see numerous synergies as we begin collaborating."

RSK Raw is the latest acquisition under RSK's funding package from Ares Capital Europe and a revolving credit facility provided by the NatWest bank announced in December 2018. RSK is investing in the development of new businesses, bolt-on complementary businesses, equipment and capabilities to increase its services and to expand internationally. RSK now employs more than 3,100 staff in more than 100 offices worldwide and has an annual turnover in excess of £250 million (US$315 million).
