Accelerating reef creation

As an eco-engineering company whose mission is to accelerate reef creation and whose business is built on science, we take great care to model scenarios and test our products for maximum efficiency, with the result being the best protective installations available on the market today. With the UK aiming to quadruple their offshore wind installations by 2030, the increase in marine activity creates numerous issues for subsea life.

“This pioneering research into the relationship between seaweed growth and synthetic structures is unique; no other studies worldwide have utilised dual-beam electron microscopy to investigate adhesion rates in this level of detail. ”

Innovation & Blue TEch

Biodiversity is a key driver that underpins our research. Providing evidence for our designs and supporting our clients’ efforts to consider the environments in which they operate. From our minimal carbon footprints to unique, patented Reef Cubes®, our USP is the speed with which species colonise our products, creating new habitats in the nektobenthic zone.

In developing our solutions using scientific theory and the latest in eco-friendly design, we have thought long-term to ensure our products leave a lasting legacy for our planet, thus by creating materials that can be left indefinitely, we reduce our interference with nature and unnecessary marine damage. 

With some 40,000 concrete matts submerged in UK waters alone, many of which require retrieval (as they’re classed as marine litter) at an estimated cost of $32m per gigawatt, ARC Marine also enable corporate adherence to policies and directives, such as the forthcoming Taskforce on Nature-related Financial Disclosures (TNFD).

This ensures that for any customers deploying ARC Marine solutions, they can be safe in the knowledge they are providing value to the planet and their shareholders, via improved corporate responsibility and supporting sustainability disclosures.

eco engineering

Our advanced casting techniques create surface textures that replicate natural reef features and niches, which in turn enhance biological recruitment – adding life to subsea infrastructure via the creation of new habitats, as well as fostering the capability to sequester carbon through natural marine attraction.



By continually monitoring our sites, we have been able to evidence habitat improvement and species restoration – crustaceans, juvenile fish, native kelp and corals, proving that by working within environmental limits, it’s possible to transition to a renewable future, whilst also improving marine conditions.

marine biology & oceanography

With human-related change altering our oceans, we have a duty to preserve and protect these ecosystems. Across physical, chemical and geographical bounds, we are committed to providing solutions that ensure nature and humanity co-exist in harmony. We, therefore, work using ecosystem-based management – modelling our technology to ensure we provide a multi-trophic future benefit across all our installations.




Through our research, we have been able to provide world-first analysis into kelp and seagrass structural adhesion in conjunction with Plymouth University, developing our Marine Crete® to deliver as many ecosystem benefits as possible. By studying Geophycology (seaweed attachment to rock), we have been able to examine fauna growth at various depths, pressures and salinity to produce a compound that is eco-friendly, offers the density needed for infrastructure support and has a minimal carbon footprint.

In collaboration with

thought leadership

Aligned to this, our installations offer wider scientific research opportunities – facilitating observational studies to better manage marine sustainability. We encourage scientific collaboration with our customers and partners to help drive advances in marine science, as well as introduce our work to the next generation. Our following case studies highlight some of the research we have undertaken.

With science-based targets underpinning global sustainability efforts since the inception of the Paris Agreement, we are uniquely positioned help meet these targets as a leading global provider of marine solutions.

Native Oyster Attachment Research

ARC have been making steps forward in oyster restoration recently. We found out that we can stick oysters to Reef Cubes, with no significant effect on their survival. The results come from a short study completed with the Marine Biological Association (MBA), in...
