A unique set of specialist skills designed for the oil and gas industry has helped a British firm secure a series of contract wins for a major operator in Australia.

Opus, whose staff is split between its headquarters in Guildford, Surrey and testing and development facilities in the Orkney island of Flotta, has custom built a number of internal and external upgrades for Apache Energy’s floating production, storage and offloading (FPSO) vessel Ningaloo Vision, off Western Australia.

The work improves the efficiency of oil production and water treatment on the FPSO as highlighted in innovative Opus analysis techniques carried out during a review last year.

The work is worth a total of £750,000 to Opus which specialises in treatments for oil separation and produced water, a by-product of petroleum production. The company, whose motto is ‘results delivered’, has an unrivalled spectrum of expertise covering trouble-shooting process studies, design, fabrication and installation of specialist equipment as well as environmental services.  

The Ningaloo Vision has capacity to process 150,000 barrels of liquids per day, including 63,000 barrels of oil, and store 540,000 barrels of oil.

Opus’ integrated procedure started with the 12-week study, providing a general overview of various process vessels, including an evaluation of the efficiency of its first stage separator and IP separator - pressure vessels used for separating fluids produced from oil and gas wells into gas and liquid components.

Theoretical assessments were performed by staff in Guildford, while colleagues in Flotta carried out scaled physical modelling of the vessels at expected future process conditions to assess the existing internals and suggest improvements.

Following on from the study and its recommendations, Opus was asked to design and supply new process internals for the separators. In addition the company was awarded contracts for internal and external modifications for the FPSO’s flotation vessel and a new inlet device for the degasser vessel.

Opus engineers adapted existing technology to provide bespoke solutions in each case.

Nigel Weir, Managing Director, said: “These contracts demonstrate the trust that our clients have in our specialist knowledge and comprehensive approach to problem solving, from consultation to design and installation of the equipment to achieve the results required by the client.

“The outcomes highlight the continuing innovation and adaptability of our staff to provide successful, cost-effective solutions.”
