Taking a turbine offline for control system upgrades left an offshore platform running on a single primary turbine. The company needed a standby power solution that could fit tight space/weight limits and tie into existing medium-voltage infrastructure.
Aggreko delivered a 2.5 MW dual-generator package (1,500 kW + 1,000 kW) that stepped up to the platform's 5 kV system, complete with isolation gear, overload protection, and full engineering and commissioning support.
The standby system allowed the customer to complete the turbine upgrades safely, reducing operational risk and keeping offshore production running without interruption.
An oil and gas exploration and production company was upgrading the control systems on its offshore turbine generators, which required one turbine to be taken offline. During this time, the platform would rely on a single primary turbine for power generation, increasing operational risk.
The customer needed a contingency energy solution that could be deployed offshore and remain on standby in case the primary turbine experienced an issue. The solution had to meet strict offshore space and weight limitations while integrating with the platform's existing medium-voltage infrastructure.
Aggreko worked alongside the customer to deliver an engineered contingency energy solution designed for offshore conditions and platform constraints. The final solution included a 2.5 MW generator package consisting of one 1,500 kW and one 1,000 kW diesel generator.
The generators operated at low voltage and were stepped up to the platform's 5 kV medium-voltage termination point, allowing the standby system to integrate with the existing electrical infrastructure. The package also included low- and medium-voltage isolation gear and medium-voltage overload protection to meet operational and safety requirements.
Aggreko provided engineering support, installation oversight, commissioning, and technician support to ensure the standby system was fully operational and ready if the primary turbine went offline.
With a contingency solution in place, the customer was able to proceed with turbine control system upgrades while maintaining operational security on the offshore platform. The standby system provided reliable backup power to support critical operations if the primary turbine went offline.
The project demonstrated Aggreko's ability to deploy multi-megawatt medium-voltage energy solutions offshore, from engineering through commissioning. By implementing a contingency standby strategy, the company reduced operational risk, protected production, and ensured continuity of offshore operations during critical equipment upgrades.
