Decommissioning
Efficient turnkey energy, HVAC, and compressed air solutions
How do you keep your decommissioning on track?
Accurate budgeting can be challenging at any stage of a project’s life-cycle, but it’s particularly challenging during the final phase - decommissioning. Numerous unseen variables can quickly impact both your schedule and cost – but working with a dependable partner with a proven track record can help you minimise the risks.
Aggreko can help you establish economies of scale across your decommissioning projects, by running multiple platforms or assets entering decommissioning as coordinated campaigns - rather than one-by-one efforts. And our tailored solutions are designed around your company’s set approach and standards.
We’re a leading provider of decommissioning solutions. With us as your partner you can import our expertise across your portfolio and into new regions via our highly-skilled teams who can leverage their understanding of local markets and operating conditions.
We also offer a fixed cost, turnkey model, which gives you better budget control and avoids project cost creep. We give you the flexibility to adapt to any circumstance over the duration of your decommissioning project – so you can stay on track to deliver your targets.
And that flexibility is of critical importance, when you consider the load demand of your asset is dependent on variables such as
- Daily decommissioning activities
- The phase of the decom
- Multiple vendor and contractor demands
- Seasonal temperature fluctuations
Having the flexibility to scale up or down to match these changes in power needs – gives you the power to keep costs optimised.

Frequently asked questions
Decommissioning is a multi-stage process that includes planning, plugging wells, dismantling infrastructure, and restoring the site. Each project must comply with strict safety and environmental standards. As offshore platform decommissioning processes often take place in remote and often temperamental environments, reliable and adaptable HVAC and industrial site closure energy solutions are critical to maintain safety, avoid delays, and control costs.
Decommissioning a well involves killing the well with heavy fluids, installing cement plugs to isolate zones, removing casing, and dismantling the wellhead. The site is then cleared and surveyed to meet regulations. It’s a high-risk process, so consistent energy and environmental control are essential for safe, efficient operations – including temporary energy for asset removal where traditional infrastructure is no longer viable.
Decommissioning includes shutting down infrastructure, managing idle assets, and dismantling equipment, often in off-grid or offshore environments. With changing energy needs and complex logistics, modern Oil and Gas decommissioning solutions – including flexible energy, HVAC, and load-on-demand – are key to staying on budget and avoiding delays, especially when conditions shift or timelines are tight.
Aggreko provides tailored, turnkey energy and HVAC solutions that adapt to your site and project phase. From cold stacking to battery storage and microgrids, we help you cut fuel costs, reduce emissions, and stay operational in remote areas. Whether you’re planning full rig decommissioning and site remediation or looking for safe and efficient energy removal, our expert support ensures timely, cost-effective project delivery.
