Success for Opus Maxim CFU

10.04.2008

Opus Maxim Ltd, has recently completed the successful commissioning of a Compact Flotation Unit (CFU) for leading energy services company, Wood Group, on behalf of Hess Limited.

The project - worth around £1.5 million - saw Opus install a fully integrated, skid-mounted CFU, including Mare's Tails, to treat two separate streams onboard the Hess-operated Triton FPSO (Floating Production Storage and Offloading) vessel, located in the UK sector of the North Sea.

The project - which aims to reduce the concentration of oil in produced water from Triton - has been hailed a great success.

Opus Maxim's compact flotation technology has assisted Triton in improving the quality of waste water, which occurs naturally in oil and gas reservoirs, enabling Hess to meet rigorous environmental standards. The Opus CFU treatment system achieved up to a 94% removal efficiency, reducing oil-in-water content on the outlet down to 10ppm (parts per million).

Nigel Weir, managing director of Opus Maxim, says he is extremely pleased with the results from the Triton commissioning, particularly as they were achieved in challenging conditions.

He said: "The robustness of the Opus system was really tested under demanding offshore conditions. Start-up and process control is excellent and the operation is very stable - we experienced wide transient inlet conditions which included varying flow rates, oil and solids inlet loading and motion.

"The CFU work on Triton was undertaken during heavy seas - with Storm Force 10 gales hitting the local area at the time of commissioning - but the team, together with the technology, successfully achieved the operational and contractual objectives.

"The rocking motion of a ship can have a detrimental effect on oil/water separation and Opus' CFU technology has been developed to withstand these conditions and so is ideal for FPSO applications."

Mr Weir added that he believes the successful completion of the Triton project heralds the start of an exciting period for the company.

He said: "We are thrilled this major project has been delivered so successfully, as our compact flotation technology has undergone an intensive and meticulous research and development programme.

"We are already working on a number of similar projects on platforms in the North Sea and with ongoing research and development to develop the technology further still, I am confident our CFU technology will play a major role in the continued growth and future success of Opus in years to come."
