Everllence’s RB Barrel-Type Compressors to Support Thai CCS Project

PTT Exploration and Production Public Co. (PTTEP) awarded Everllence a contract to deliver two RB-type compressor skids for Thailand’s first carbon capture and storage (CCS) project at the Arthit gas field in the Gulf of Thailand. The units will support PTTEP in capturing and storing up to 1 million tons of CO₂ per year. These skids will be installed offshore in the Arthit field, with storage operations scheduled to begin in 2028.

“For a project of this importance, close collaboration with the customer and a strong local presence are essential,” said Luntharima Somchit, Sales and Business Development Manager, Everllence Thailand. “We have worked closely with PTTEP throughout the project development phase, coordinating customer interfaces and aligning technical and operational requirements. This local involvement will remain central as the project moves into execution and operation.”

The company’s supply scope includes two compressor trains based on RB barrel-type compressors for CO₂ handling and reinjection, with both units driven by gas turbines from Solar Turbines and supplied as a closely integrated solution. Additionally, Everllence will supply a comprehensive dynamic process simulation, allowing the compressor systems to operate at full potential regarding process efficiency.

“Radial barrel compressors are designed to deliver high efficiency and reliability in demanding offshore environments,” said Markus Hons, Branch Manager of Thailand, Everllence. “For the Arthit project, we provide a tailored configuration that supports stable long-term CO₂ compression while allowing seamless integration into PTTEP’s existing infrastructure. We are delighted to contribute our expertise to such a milestone initiative and to support Thailand in achieving its national CO₂ reduction goals.”

PTTEP’s investment in the Arthrit field represents Thailand’s first large-scale usage of CCS technology and is recognized as a flagship greenhouse gas reduction initiative under the Nationally Determined Contribution Action Plan on Mitigation 2021-2030.

“We are proud to contribute to Thailand’s first CCS project and to support PTTEP in this pivotal step towards the country’s decarbonization ambitions,” said Daniel Schmidli, Head of Sales Industries SEA, Everllence. “CO₂ capture and storage is becoming an indispensable lever for reducing emissions in gas production. With our compressor technology, we bring proven expertise and robust performance to a project that sets an important precedent for the region.”

Supplying Guyana

In February 2026, MODEC contracted Everllence to supply four compressor trains for a newbuild floating production, storage, and offloading (FPSO) vessel in the Hammerhead field offshore Guyana. The complete scope includes four barrel-type RB compressor trains: two low-pressure gas compressors and two export gas compressors. Also, the delivery includes comprehensive dynamic process simulation, allowing the compressors to operate at full process efficiency.

These compressors will be electrically driven and, upon startup, will help maximize the quantity and efficiency of gas production from the Hammerhead field. The low-pressure gas compressors will feature variable frequency drives, while the export gas compressors will leverage fixed-speed drives. Everllence will design, manufacture, and test the compressors at its facility in Zurich, Switzerland.
