In order to help reduce the destruction of Posidonia seagrass beds, SUBMON has obtained the license to commercialize a low impact mooring system, marketed under the name of NARVAL^®.

NARVAL^® is a mooring system designed to be installed in sandy substrates with presence of Posidonia or other phanerogams. Its installation is respectful with the environment, and it has a low maintenance cost and high durability. It has already been successfully tried in Medes Islands and Portlligat.

These systems are very resilient, allowing the safe and comfortable mooring of vessels, and can effectively replace two of the main causes for the destruction of large areas of seagrasses: concrete blocks and free anchoring.

Together with the installation of these mooring systems, SUBMON also offers quick diagnosis to map seagrasses in mooring areas and fields of buoys, determine how many and which traditional mooring systems affect the seagrass, and stipulate whether to remove them, re-locate them or change them for low impact mooring systems.
