Opus Commissions CFU Package

Opus has recently completed a project to commission their skid mounted compact flotation unit (CFU) supplied to a major international oil and gas company.

The project, which was worth around £1.5 million and saw Opus design, construct and install the unit onboard one of the client’s oil platforms located in the Danish region of the North Sea has been hailed a great success.

The CFU will enhance the environmental performance of the platform and, specifically, improve the quality of produced water discharged to the sea.

The commissioning process involved Opus personnel configuring the CFU to determine its optimum performance settings and saw a team from the company work onboard the platform to ensure the technology was working as efficiently as possible.

As part of the project, Opus also provided analysis equipment to measure the performance of the CFU during optimisation and trained personnel onboard the platform on how best to operate the unit.

Both Opus and its client worked closely to establish performance targets for the unit and the commissioning resulted in all specified levels being met.

The CFU routinely treats 500m³/h of produced water, reducing the oil-in-water content to below 15ppm, and the system – which treated from around 50m³/h to 750m³/h of produced water during the commissioning process – maintained stability during high levels of turndown.

The unit is the latest in a series of CFUs Opus has designed and installed, having previously provided units for Wood Group, on behalf of Hess, and Petrofac for its North Sea-stationed Heather platform.

The company recently delivered its latest unit for J Ray McDermott Engineering, for treating produced water onboard an FPSO vessel, located in the Brazilian offshore region.

Nigel Weir, managing director of Opus Maxim, commented: “We worked extremely closely together with our client on this project to ensure the performance of the end product was maximised.”

“The commissioning programme confirmed the CFU will have a major impact on the enhancement of the platform’s environmental performance and the successful completion of this project is another exciting development for Opus.”
