Our Story

From our head office in Hull, OSL has grown to a 100+ strong team of experienced and innovative engineering consultants.

Established in 2005 our team of industry leading technical specialists work seamlessly with clients to deliver safe and successful projects across energy intensive and hazardous process industries. These include established ones such as Gas Processing and Transport, Refining, Chemicals, Energy, and Food, but we are also active in emerging areas within the energy transition such as processes for Carbon Capture and Storage, Hydrogen fuel as well as reprocessing through Waste Conversion.

We deliver high quality engineering design and project delivery services for all stages of project development from Concept, Feasibility/ pre-FEED, FEED, Detailed Design, EPCm and through to start-up and ongoing performance enhancement.

Our stage gate development approach is widely recognised across the industry as good practice to ensure the level of design and project maturity de-risks the next stage of project development and financial commitment.

We also provide bespoke engineering and technical consultancy to assist our clients across the globe with “day-to-day” requirements, support site upgrades and solving operational problems.

We’re proud of our impressive client base of businesses from SMEs to international companies that are spread across the UK, Spain, Germany, Norway, Africa, South America and the Middle East.

Our growth and export achievements have been recognised by the team winning industry awards including "Start-Up Business of the Year" ; "Small Business of the Year" in the Humberside area; and the EEEGR (East of England Energy Group) SNS Rejuvenation Award for the development of a subsea separator.
