Decommissioning

The North Sea Transition Authority (NSTA) estimates that £24bn will be spent on decommissioning offshore infrastructure between 2023 and 2032 – a £3bn increase from previous forecasts. As offshore infrastructure reaches the end of its operational life, developers and governments face mounting financial and environmental pressures to manage decommissioning in a sustainable, cost-effective way.

Traditional decommissioning involves removing, dismantling, and disposing of offshore platforms, subsea structures, and pipelines – a complex, high-risk, and expensive process. After decades in the ocean, these structures often serve as thriving marine habitats, and full removal can cause significant disruption to surrounding ecosystems. With decommissioning costs partially offset by government tax reliefs, reducing these expenses directly benefits both developers and taxpayers.

Our goal is to better this process with our unique suite of products that are much longer lasting, designed for scale and multi-application, and contain no plastic and reduce carbon.

    Nature-Inclusive Decommissioning

    Decommissioning presents an opportunity to reduce costs while preserving marine biodiversity. ARC Marine’s Reef cubes and Reef mats offer a sustainable alternative by providing long-term, environmentally friendly subsea protection that supports thriving marine ecosystems.

    Reducing Decommissioning Costs & Environmental Impact

    All our solutions can be deployed in place of decommissioned infrastructure, reintroducing marine life while maintaining regulatory compliance. Additionally, Reef mats increase the likelihood of exemption from removal under comparative assessment guidelines, making in-situ decommissioning a viable and cost-saving option. Each retained unit can save over $13,000 USD in decommissioning costs, allowing developers to leave a positive environmental legacy while meeting project obligations efficiently.

    PAS 1401-Compliant Nature-Inclusive Design

    Engineered to the highest environmental standards, delivering both structural integrity and ecological benefits.

    Seamless Replacement for Existing Infrastructure

    Equivalent or superior to traditional subsea protection methods while significantly lowering environmental impact.

    Certified for Zero Environmental Risk

    Third-party leachate certification confirms no toxins or pollutants are released, even in a degraded state.

    Ongoing Habitat Enhancement

    Structures remain on-site, protecting and enhancing biodiversity rather than destroying it during removal.

Each retained Reef mat can save over $13,000 USD in decommissioning costs, allowing developers to leave a positive environmental legacy while meeting project obligations efficiently.

  • Consultation

    The first phase is to talk things through and gauge your situation, and which of our products is the best solution for it. We would establish the scale of the requirements, location, application and anything else bespoke that may be required for your project.

  • Design

    We then work closely with our in-house science and engineering teams to create tailored designs based on the deployment location and project goals.

    This enables us to deliver a nature-inclusive design to reflect the local marine environment and target the growth of specific species.

  • Manufacturing

    At this stage, we ensure all our products are built as close to the deployment location as possible, using local labour and raw materials where possible.

    Further carbon reductions and cost savings occur through manufacturing “in country” and utilising a combination of our globally transportable mobile production plant and using local raw material suppliers.

  • Permits & Licensing

    We will assist with bid writing right from the tender stage & compliance through to conditions, obtaining permits and licensing for deposits onto the seabed with government bodies.

    We can even take care of stakeholder management with fisheries, government, community groups and governing boards.

  • Transport & Logistics

    Local deployment at your project location ensures that the entire process supports the local economy and follows industry-standard procedures with industry-standard hardware and vessels for added efficiency. We also have our own portfolio of deployment equipment that has been designed by our team from over 30 years of industry experience

  • Monitoring

    Pre & post-deployment, we can deploy multiple monitoring techniques such as eDNA or ROV’s to assess the effectiveness of our subsea protection and artificial reef products. This allows us to track progress, monitor the development of marine life, compared to the baseline and fine tune our solutions for optimal results.
