What CR3 does

CR3 Group is an energy engineering solutions provider founded in 1991 and headquartered in Singapore, delivering industrial maintenance, catalyst handling, shutdowns and turnarounds, plant revamps and EPCC services to world-class customers in oil and gas, refining, petrochemical, power, renewables and other asset-intensive industries across Asia-Pacific and the Middle East. With over 6,000 full-time professionals and permanent facilities in Thailand, Singapore, Malaysia, India, Vietnam and the UAE, CR3 operates as a regional field-services platform built around proprietary and licensed technologies including CR3 Decoking Technology (CDT), Eco-Hydrodrilling, the CR3 Dense Loader, the Automated Four-Drum Tipper, and the ZymeFlow chemical decontamination portfolio, supplemented by technical alliances with partners such as Koch-Glitsch, Unidense, UOP and Samsung E&A.

The company generates revenue primarily through project-based professional services contracts for planned and unplanned maintenance, catalyst change-outs, industrial cleaning, mechanical and plant maintenance, pipeline services, fabrication, and pre-commissioning and commissioning work, with go-to-market executed through direct enterprise field sales targeting large energy and process-industry customers. CR3 reported 32% revenue growth in 2022 driven by long-term maintenance contracts, has mobilized 1,400+ personnel on a single shutdown, and operates under ISO 9001, ISO 18001, ISO 45001, ASME 'U', NBBI 'R'/'NB' and IRATA certifications. Recent strategic moves include the common-ownership integration with ZymeFlow, a Long-Term Cooperation agreement with Samsung E&A signed at ADIPEC 2025, new chemical blending facilities in Thailand and India, a Vietnam office opening, and senior leadership appointments to support continued geographic and product expansion into renewables, sustainable aviation fuel and mercury management.
