Global engineering company Worley said February 9 its Aberdeen office had been awarded £765,000 (US$1.03mn) from Scottish Enterprise, Scotland’s national economic development agency, for pre-production testing of its pseudo dry gas (PDG) liquid removal system.

The PDG system is part of the company’s enhanced subsea gas tieback project that reduces operational CO2 emissions in gas fields by 90%. The technology removes the need for costly topsides and compression by reducing back pressure in the pipeline. This reduces the associated high carbon emissions and allows for greater tie-back distances.

“As the energy industry strives towards sustainability, it’s important to support solutions that enable decarbonisation,” said Andy McDonald, head of low carbon transition at Scottish Enterprise. “The pseudo dry gas technology…will contribute to lower carbon emissions across industrial processes and highlights the innovation taking place across the energy industry in the northeast of Scotland.”

Worley’s pre-production testing will build upon a prototype which was created and tested in 2020. A large scale-unit will be built and tested under typical subsea pressures and with a variety of hydrocarbon fluids.

Last month, Worley won a two-year contract for engineering, procurement and construction work at three North Sea projects.
