Aggreko has teamed up with Katoni Engineering to deliver a tailored temporary power solution that cut both costs and emissions during a recent North Sea offshore platform turnaround.
The 50-day project—covering turnaround (TAR) operations as well as plug and abandonment (P&A) and decommissioning work—traditionally relied on low-load diesel turbines, a method that often results in inefficiency and higher emissions. By deploying Aggreko’s Stage V generators in modular containerized systems, engineered to meet the platform’s reduced load profile, the partners helped operators avoid nearly £900,000 in additional fuel costs and prevent 4.5 tonnes of CO₂ emissions.
The solution was tailored by Katoni Engineering to integrate with the platform’s safety and power systems, while Aggreko provided one of Europe’s largest rental fleets and round-the-clock maintenance support to ensure operational continuity.
Industry leaders highlighted that such supply chain collaboration is becoming critical as North Sea operators face intensifying decommissioning activity, emissions compliance under the UK ETS, and cost pressures.
“Reliable, compliant and low-emissions temporary power has moved from optional to essential,” Aggreko’s Craig Ballantyne said. “Early engagement with the supply chain will be key to ensuring operators maintain continuity while responsibly winding down offshore assets.”
Katoni Engineering echoed the sentiment, noting that emissions and cost pressures are as much about planning and procurement as technical challenges. Their partnership with Aggreko, they said, demonstrates the importance of tailored engineering solutions in helping operators manage late-life assets effectively.
As decommissioning accelerates across the UKCS, projects such as this highlight how innovations in temporary power can play a decisive role in reducing costs and meeting emissions targets without sacrificing operational integrity.
