Repurposing Offshore Rigs and Platforms

Breathing new life into existing oil assets

Transforming assets, extending life, and reducing environmental impact through engineering expertise.

Innovation is something that comes naturally to us at NOV and we’re using our expertise to re-energize current offshore rigs and platforms. By extending the life of in-service equipment we can mitigate the financial and environmental costs of the decommissioning process. Repurposing and transforming existing equipment will protect marine life around the steel structure, whilst reducing emissions and landfill waste.

Our global footprint of field and after-market services make yesterday’s assets ready for the challenges of tomorrow. Reusing the asset completely removes the complicated and resource heavy processes that can arise when decommissioning. With our supply chain development strategies, we are uniquely positioned to make a real impact when it comes to repurposing old equipment.

Environmentally, offshore rigs and platforms serve as an ecosystem for a range of marine life. Mussels, barnacles, crab, and shrimp rely on these structures, and are usually protected by fishing regulations. By extending the equipment’s life we can protect this established ecosystem and eliminate any impact on the proposed disposal site. By removing the need demolish the structure we can also avoid the environmental damage that comes from mechanical removals. Repurposing the equipment reduces energy consumption and output, helping us meet the challenge of reducing emissions.

Integration and design

With our engineers and key industry relationships we can repurpose fixed platforms, jack-ups, semi-submersibles, floating production, storage and offloading (FPSO’s) vessels, and drillship’s with integrated solutions:

  • Concept, Pre-FEED, FEED and supply of modular units
  • Repurpose of topsides and hull of existing units
  • Weights savings with fiber glass composite solutions
  • CO2 transportation and injection vessel designs
  • Flexible pipe, high pressure, high corrosion resistance
  • Subsea wellhead / equipment for CO2 injection
  • Repurpose existing wells, inspection, assessment, repair
  • Drilling new wells for CO2 injection
  • Digital - monitoring services and safety systems

Carbon Capture, Utilization and Storage

We understand the complexities operators and industry emitters across the globe face in selecting a partner for carbon capture, utilization, and storage (CCUS) projects of any scale. With more than three decades of global process engineering and gas treatment expertise, NOV can engineer, design, and fully execute built-for-purpose carbon capture systems for many industry applications.

Hydrogen

As we push towards a decarbonized future, hydrogen production will play a larger role in meeting and delivering sustainable, economic, renewable, and transportable energy goals. We stand ready to support this growing sector through our experience in developing and supporting offshore wind farms, producing water treatment systems, and applying our global process expertise in large-scale offshore projects.
