What ARC Marine does

ARC Marine is a UK-based eco-engineering company founded in 2015 that designs, manufactures, deploys, and monitors Nature-Inclusive Design (NID) solutions for marine infrastructure. The company serves enterprise and government buyers across offshore wind, coastal defence, fisheries and aquaculture, marine restoration, oil and gas, and ports/harbours, replacing conventional rock armour and high-carbon concrete with proprietary modular units (Reef cubes, Reef mat, Reef wall) that deliver equivalent engineering performance while creating marine habitat. Its Chief Scientific Officer authored PAS 1401:2025, the British Standard for Nature-Inclusive Design in marine environments, positioning ARC Marine as the technical authority in its category.

Revenue model

1. Reef Infrastructure Product Sales: Sale of proprietary artificial reef and scour protection products including Reef cubes, Reef mat, and Reef wall. Products are sold directly to enterprise clients for use in offshore wind, coastal defence, fisheries, and restoration projects. Revenue is project-based, driven by contract wins and large-scale deployments. Products can be purchased as standard off-the-shelf units or as bespoke solutions tailored to specific project requirements.
2. Turnkey Project Services: End-to-end project delivery including consultancy, design, manufacturing, deployment, monitoring and decommissioning services. Offered as a full turnkey service or as individual service components. The company works closely with clients from consultation through to post-installation monitoring, providing scientific expertise and engineering validation throughout.
3. Nature-Inclusive Design Consultancy: NID consultancy services including Biodiversity Net Gain (BNG) assessments, strategy, bid support, regulatory compliance, and habitat metric analysis. Provided by in-house science and engineering teams to developers, project teams, and policymakers seeking to integrate biodiversity enhancement into marine infrastructure.

Products and services

• Reef cubes Modular artificial reef units made from proprietary low-carbon Marine Crete with up to 98% recycled aggregates, featuring a spherical central chamber with passages on each cube face and advanced surface textures designed to PAS 1401 Nature-Inclusive Design principles. Used by offshore wind developers, coastal defence clients, fisheries operators and conservation organisations for scour protection, artificial reef creation and biodiversity enhancement in intertidal and subsea environments. Available in multiple sizes including a 1m cube variant.
• Reef mat Nature-Inclusive articulated concrete mattress for subsea cable and pipeline protection. Manufactured from low-carbon Marine Crete using up to 98% recycled aggregates, zero plastic, and certified Dutch leachate (non-leaching). Compatible with existing offshore installation methods and provides equivalent or superior engineering performance to conventional protective mattresses while delivering biodiversity uplift. Each retained Reef mat can save over $13,000 USD in decommissioning costs.
• Reef wall Coastal protection product built using Nature-Inclusive Design principles, manufactured from low-carbon plastic-free Marine Crete as modular units. Designed to deliver structural coastal defence equivalent to traditional materials while creating biodiversity-enhancing intertidal habitat. Deployed in projects such as BCP Council's Hengistbury Head Long Groyne where 13 carbon-neutral Reef cubes were installed.
• Turnkey Project Management Services End-to-end project management service covering design, manufacturing, deployment and decommissioning of Nature-Inclusive Design reef installations. Offered to enterprise clients as a full turnkey package or as individual service components, with ARC Marine working closely with clients from consultation through to post-installation monitoring. Includes specialist deployment vessels and equipment for offshore, coastal and intertidal projects.
• Nature-Inclusive Design Consultancy Consultancy services covering Nature-Inclusive Design (NID), Biodiversity Net Gain (BNG) assessments, regulatory compliance strategy, bid support, and habitat metric analysis. Delivered by ARC Marine's in-house science and engineering teams to developers, project teams, policymakers and conservation organisations seeking to integrate biodiversity enhancement into marine infrastructure projects. Includes support for PAS 1401:2025-aligned design principles.
• Monitoring & Maintenance Services Monitoring and maintenance services including baseline and post-installation ecological surveys to verify biodiversity outcomes, species abundance, habitat utilisation and structural performance of deployed reef installations. Supports client reporting against regulatory and ESG requirements including BNG, NID and PAS 1401:2025 compliance.
• Bespoke Solutions Bespoke design, engineering and manufacturing service for clients with non-standard project requirements. Delivers custom reef structures, specialist equipment and tailored deployment solutions based on the Marine Crete material platform and Nature-Inclusive Design principles, including the RIB (Reef cubes In a Box) transportable manufacturing plant for in-country local production.

Direct peers

• ECOncrete Tech: Israel-based developer of bio-enhancing concrete solutions for coastal and marine infrastructure, including reef-friendly seawall and armour units. Directly comparable to ARC Marine in offering nature-inclusive alternatives to conventional marine construction materials, targeting ports, offshore energy and coastal developers.
• Living Seawalls: Singapore-based eco-engineering company producing modular habitat panels for seawalls and coastal structures. Closely analogous to ARC Marine's Reef wall/wall products in combining engineered coastal protection with biodiversity uplift on marine built infrastructure.
• Reef Design Lab: Australia-based designer of artificial reef modules and 3D-printed reef structures for marine habitat restoration. Comparable to ARC Marine's Reef cubes in producing modular reef units for coastal, port and environmental projects.
• Natrx: US-based climate-tech company manufacturing nature-based coastal and marine infrastructure using 3D-printed composite materials. Targets similar customers (coastal resilience, habitat creation) with modular engineered solutions akin to ARC Marine's Reef cubes.

Broad incumbents

• Royal HaskoningDHV: Global engineering consultancy with established Nature-Inclusive Design practice and active involvement in PAS 1401 steering group. Larger incumbent offering broader port, coastal and offshore engineering services; competes indirectly as consultant and NID methodology developer.
• VolkerStevin: UK-based tier-1 marine and civil engineering contractor with extensive coastal defence and port infrastructure portfolio. Indirect competitor/partner as it delivers large-scale UK coastal schemes that increasingly require nature-inclusive solutions.
• Boskalis: Global marine contractor (and ARC Marine partner on offshore projects) offering dredging, subsea protection and offshore wind services. Large incumbent that could potentially internalise nature-inclusive scour protection or partner at scale.
• CEMEX: Global building materials major with growing portfolio of lower-carbon concrete (Vertua, AACM-style products) and marine infrastructure exposure. Represents the commodity-scale competitive threat to Marine Crete as low-carbon concrete becomes more competitive.

Emerging players

• BiOceanOr: France-based artificial reef developer producing modular reef structures for biodiversity and fisheries enhancement. Comparable niche competitor focused on European marine restoration, with overlapping product/market fit to ARC Marine's smaller Reef cubes deployments.

Regional players

• Subcon International: Australia-based marine construction and artificial reef specialist. Comparable in artificial reef deployment capability but focused on APAC markets; serves as a regional benchmark for ARC Marine's international expansion via RIB.
