Testing Worley’s Pseudo Dry Gas Liquid Removal System Prototype

INTECSEA, part of the Worley Group, a leading global provider of professional services in the energy, chemicals and resources sectors, selected the world-leading facilities at TÜV SÜD National Engineering Laboratory in Scotland for the latest test phase of their ground-breaking Subsea Gas Tieback Project. This innovative endeavour aims to reduce operational CO₂ emissions in gas fields by over 90%.

The prototype included the 14 tonne unit, a magnetic drive subsea pump, and a supporting subsea control system. These were installed and tested in the Advanced Multiphase Facility (AMF) as a single system under pressures of more than 130 bar over the expected operational envelope, with a variety of hydrocarbon fluids, in both the horizontal and angled at 2 degrees orientation to simulate subsea conditions.

Lee Thomas, senior project engineer at Intecsea said:

“TÜV SÜD has played a pivotal role in this project. Through their expertise and state-of-the-art facilities, we were able to perform high-pressure flow loop testing of our Pseudo Dry Gas unit. The team here are experts in this field and we definitely made the right decision to partner with TÜV SÜD.”

Dr Zak Latif, AMF technical lead commented:

“Our team has done a fantastic job to design, adapt and deliver everything to meet Worley INTECSEA’s needs. Our Advanced Multiphase Flow Facility is capable of providing high-pressure, high-flow rate multiphase testing and calibration that matches real-world field conditions and we were excited to use it for this ground-breaking project.”

The Enhanced Subsea Gas Tieback Project reduces operational CO₂ emissions in gas fields by more than 90 percent, while increasing technical and commercial viability.

The technology removes the need for topsides and costly compression by reducing back pressure in the pipeline and the shape of the resistance curve. This in turn reduces the associated high carbon emissions and allows for greater tie-back distances.

The team at TÜV SÜD were pleased to support Worley INTECSEA and the wider group of industry partners on this test phase and look forward to collaborating on future developments.
