Decommissioning done right: Temporary power solutions for a safer, cleaner exit
Introduction
Powering responsible decommissioning in Europe's energy transition
As Europe accelerates toward decarbonisation and asset retirement, oil and gas operators face mounting pressure to decommission responsibly, safely and economically. From late-life production to plug and abandonment (P&A), managing power and temperature needs during this phase is crucial to controlling costs and minimising environmental impact. At Aggreko, we provide temporary power and HVAC solutions tailored to meet these challenges.
Why decommissioning needs a fresh approach
Decommissioning is a complex, multi-phase process with high financial and environmental stakes. Fixed infrastructure is often outdated or unsuitable for reduced operational demand, and shutting down facilities can bring new risks:
- Grid disconnection or limited access to reliable power
- Asset degradation during idle periods (especially offshore)
- High recommissioning costs if assets are reactivated later
Without proper planning, operators may face extended downtime, non-compliance penalties, or unexpected repair costs.
How a ggreko supports decommissioning projects
Aggreko delivers modular, mobile power and temperature control solutions designed to adapt to your decommissioning timeline and technical constraints.
Our services include:
- Cold stacking: Preserve rig assets with dehumidification and HVAC systems that prevent corrosion and equipment degradation.
- Temporary power: Maintain essential systems and lighting using generators compliant with EU and offshore safety standards.
- Load banks and testing: Support final commissioning, integrity testing and emergency power validation.
- Remote monitoring: Optimise fuel usage and reduce technician visits with real-time diagnostics and alerts.
Case in point: offshore cold stacking success
In a recent North Sea application, Aggreko provided a complete cold stacking solution for an offshore platform entering a multi-year preservation phase.
Using our HVAC and dehumidification fleet, combined with remote monitoring and bespoke power supply, we:
- Reduced humidity-related equipment failures by over 40%
- Cut reactivation timeline by 3 months
- Lowered preservation costs by eliminating the need for on-site generator crew
The sustainable dimension: lower emissions from start to finish
Using temporary power avoids the need for fixed infrastructure upgrades and enables operators to right-size their energy use. Our Stage V generators and Greener Upgrades – including battery storage and HVO-compatible units – help you:
- Stay compliant with EU emissions regulations
- Cut CO2, NOx and particulate matter significantly
- Transition smoothly from diesel to hybrid or gas-powered operations
Conclusion
Decommissioning doesn't have to mean downtime, risk, or excessive cost. With Aggreko as your partner, you can exit responsibly, protect your assets and plan your next move with confidence.
