Our custom-designed frond mattresses are created specifically for the
harshest marine environments.
Benefits of our fronds include:
- Ability to use longer 1.5m fronds due to the UV stabilised 200 Denier Woven PP on the base mattress
- Improved reduction in velocity of current particles (up to 50% decrease)
- Faster burial of surrounding subsea assets
- Environmentally friendly due to the ability to act as a nursery for small fish
The fronds can be attached to concrete mattresses, grout bags, grout inflated fabric formworks or chain ballast. The fronds are secured for installation with a Velcro cover complete with buoyant monkey fist and a bridle for deployment. This allows the mats to be safely installed by ROV or divers.
