SES Energy has acquired Aberdeen-based CIU (Chemical Injection Utilities) from ICR, taking sole ownership of CIU’s chemical injection utilities and corrosion monitoring services, along with a 49-strong technical team.
The deal expands SES Energy’s chemical and tank offering and adds specialist capability in two service areas that sit directly on production uptime and asset integrity. Chemical injection underpins routine flow assurance and protection strategies in offshore and onshore operations, while corrosion monitoring provides the feedback loop that confirms whether inhibition programmes and operating conditions are performing as expected.
SES Energy said it will continue as an authorised distributor and service centre for Williams, Milton Roy, and Kenco Engineering products. It is also bringing CIU director Alan Simpson into the business as part of the transaction, positioning the move as a continuity play for customers and existing technical relationships.
Manfred Vonlanthen, chief executive officer of SES Energy, said: “This milestone sets SES Energy on an accelerated path to global growth, as we embrace the next phase under our new ownership. CIU is a business that has built an excellent reputation for quality, reliability and consistent service delivery — values that align closely with ours.”
He added that the combination strengthens the group’s global chemical and tank offering, and sets up wider deployment of CIU’s specialist capabilities through SES Energy’s international footprint. SES Energy operates across multiple regions and has been building out service breadth following its acquisition by Davidson Kempner and subsequent rebrand from Swire Energy Services.
For CIU, the transaction lands at a time when chemical management and integrity assurance are being pushed harder by ageing assets, tighter operational windows, and the rising cost of unplanned intervention. Corrosion monitoring services — typically built around a mix of probes, coupons, data collection, and interpretation — are increasingly being treated as an operational necessity rather than a periodic check, particularly where operators are balancing inhibition performance against chemical spend and emissions targets.
Alan Simpson, CIU director, said: “The energy market increasingly relies on specialist chemical injection services and corrosion monitoring. We have spent years building the expertise and reputation that customers can depend on and joining SES Energy allows us to maintain that trusted service from day one — while opening the door to new opportunities.”
He added: “For our customers, this means continuity, reliability and access to a wider global platform. For our team, it means stability, growth and the chance to bring their skills to projects around the world.”
While financial terms were not disclosed, the acquisition signals a clear direction of travel: bundling operational services around equipment provision, logistics, and lifecycle support, and presenting operators with a broader “single supplier” proposition across critical offshore and energy transition-adjacent activities.
