Marinecrete Mattresses ("Marinematts")
Carbon Negative Subsea Protection
Marinecrete mattresses (Marinematts) are pre-cast eco-friendly low/negative CO2 concrete structures that protect man made subsea assets whilst enhancing the marine environment due to their cavities, pH and surface texture. They are non-toxic, contain no Portland cement, zero plastics and are made with >95% recycled materials supporting the circular economy. Standard Marinecrete mattress measure 6x3m and can be deployed using conventional lifting frames. They can be part of the energy transition to carbon net zero projects and support green recycle, repurpose, reuse strategies. There use supports UN goal SDG-14 life below water.
Marinematts are designed to become the defacto standard for protecting cables, pipelines and monopiles due to their massive CO2 saving, the potential life cycle cost saving (if approved to be left in situ) and nature inclusive design benefits. They are recoverable so they can be moved and reused but designed with the potential to be approved by regulators to be left in situ forever due to their positive marine impact. Every subsea and coastal defence project can now leave a positive marine legacy to help rewild the oceans and provide hard substrate to regenerate ocean health.
