Through their partner company AMOG Consulting, Moorsure has developed a new artificial reef offering to the market which delivers similar capability to other offerings, but is cheaper and easier to install.
The individual reef units are in essence a reinforced concrete cylinder;
– 4.5 m in diameter
– 6 m in height
– 82.1 m3 internal volume (allowing for 0.5 m settlement into the seabed)
– Weighing 10 tonnes in air, 5.9 tonnes in seawater
– Containing 4.3 m3 TSMR concrete in the main cylinder
– With an additional semi-hemispherical cavern module free standing in the base, installed concurrently with the main cylinder
This cylinder is cast with a complex of voids to enable fluid flow into and out of the unit, creating turbulence at the many edges, and, by virtue of blockage and natural chimney effect, current flow up through the centre of the unit.
It will be formed leveraging a departure from the conventional concrete precasting techniques enabled by the use of advanced reinforcing technologies. This departure allows more organic complex shapes to be created in a cost effective manner, by local contractors, with the minimum of materials. It also enables the life of the unit to be that of the concrete itself, with no concerns of spalling through corrosion of internal steel reinforcement.
Each unit will be individual and unique. Its complex of voids and vertical surface more varied like the natural structures it seeks to imitate. Some units will have more voids to give complex vertical relief. Other units will have smaller voids, giving shelter, increased upwelling and protection.
