All floating foundation technologies need a mooring system attached to the seabed. Recognising that bottom-fixed foundations use monopiles or jackets to anchor to the seabed, mooring systems are an important target for the floating wind cost reductions needed to compete against bottom-fixed offshore wind.

The problem is the large mooring spread required by catenary mooring systems. This mooring spread — the seabed area required for anchoring the unit — expands significantly as water depth increases.
