Offshore oil and gas decommissioning

Rental equipment for offshore oil and gas decommissioning

Offshore oil and gas platforms don’t last forever. As more facilities reach the end of their design life or economic viability, operators face the challenge of dismantling them safely and responsibly. Decommissioning is a complex but necessary step, whether it’s the full or partial removal of structures, recycling materials, transforming platforms into green energy hubs, or even repurposing them as artificial reefs.

 

Industry forecasts show a sharp rise in offshore decommissioning projects in the coming decade: on the UK Continental Shelf alone, more than 2,000 wells are expected to be abandoned by 2034, with up to 20 topside facilities decommissioned annually. For operators, this means growing demand for temporary air, power, and nitrogen to keep projects running safely and in compliance with tightening regulations.

 

With a proven track record worldwide, Atlas Copco Specialty Rental provides certified, offshore-ready equipment and expert support for every phase of your decommissioning project:

Driving pig trains for pipeline cleaning and flushing

Effective cleaning and flushing of pipelines are critical steps in the decommissioning process. Pigging involves propelling devices known as "pigs" through pipelines to remove deposits, debris, and ensure the line is free from contaminants. Our high-pressure air compressors and boosters (up to 345 bar(g)) provide the necessary force to drive pig trains through pipelines of varying lengths and diameters, ensuring thorough cleaning and preparation for subsequent phases.

Nitrogen purging during well-plugging

When wells are plugged, safety comes first. Our nitrogen generation systems provide high-purity nitrogen on site (95–99%), displacing oxygen and combustible gases to ensure an inert, safe environment. Containerized solutions integrate seamlessly with compressors for hassle-free offshore deployment, eliminating the need for bulk nitrogen supply.

Preparing installations for topside removal

Before dismantling topsides, systems must be depressurized, purged, and dried to meet environmental and safety standards. Our Class Zero oil-free compressors, dryers, and air treatment equipment ensure that topside installations are fully prepared for removal, reducing hazards and meeting strict compliance requirements.

Offshore power to decommission substations

Once existing power systems are offline, decommissioning operations require a reliable and scalable energy source. Our compact, offshore-ready diesel generators (up to 1450 kVA) and marine-certified accessories provide flexible power for substations and utilities. To further cut fuel consumption and emissions, we integrate Battery Energy Storage Systems (BESS), enabling hybrid power setups that smooth loads, reduce runtime, and even allow for silent operation when needed.

Expert offshore support

Our offshore-certified technicians (BOSIET and/or GWO) are available on site, ensuring safe setup, smooth operation, and continuous performance throughout your campaign.

Certified offshore equipment

All units come with offshore lifting frames (DNV 2.7-1 certified), corrosion-resistant coatings, and integrated safety features including spark arrestors, automatic fire extinguishers, gas detection, and spillage-free frames.

Emission-conscious solutions

We support operators in navigating between legacy rig-safe equipment and modern Stage V-compliant units, offering hybrid setups that combine low emissions with practical offshore deployment. With the right sizing and monitoring, our solutions help you save fuel, reduce CO₂, and cut exposure to ETS costs.

Complete rental solutions

Offshore decommissioning is entering a new phase. With rising activity, evolving environmental standards, and new technologies like Stage V and hybrid energy storage systems coming into play, success will depend on collaboration and foresight. That’s why we don’t only provide compressors, nitrogen generators, and power packages, but we also share knowledge, anticipate challenges, and co-create resilient solutions with you.
 
So let's start a conversation and see how we can help with: 
 
  • Air: Rig Safe compressors with boosters up to 345 bar(g), combined with dryers, receivers, manifolds, and hoses for complete pipeline and topside preparation solutions.
  • Nitrogen: On-site generation with containerized membrane units, delivering 95–99% purity with maximum offshore safety and flexibility.
  • Power: Marine diesel generators up to 1450 kVA, available with full distribution packages and transformers up to 25 kV. For lower emissions and optimized fuel efficiency, hybrid setups with BESS reduce both costs and environmental impact.
