MODULAR ROCK INSTALLATION SYSTEMS

CONCEPT DESIGN FOR OFFSHORE WIND AND DECOMMISSIONING MARKET

PHILOSOPHY

The worldwide developments in the offshore wind market, increases the demand for scour protection and seabed preparation around fixed offshore structures. Also the
protection of power cables around windfarms requires rock coverage where cable burial is not possible. To fulfil the request for smart and efficient rock installation
solutions, Vuyk developed a modular rock installation system in close cooperation with Seatools, the specialist in underwater technologies. The philosophy is a modular system which, dependent on market developments and customer strategy, can be upgraded in capacity and extended in functionality. With a modular arrangement, the basic modules can be supplemented at any moment in the system lifetime.
