Crane Vessel

VESSEL FOR LIFTING OR TRANSPORTING HEAVY OFFSHORE STRUCTURES.

Heavy lift crane vessels are mainly used as work ships to transport and install offshore structures, such as substations and offshore foundations. The vessels are often designed as multihulls to ensure a stable position in the water, especially for crane tasks. Instead of applying counterweights as is common practice onshore, these vessels are able to flood their ballast tanks in the hulls to achieve additional stabilisation during a lifting process. Usually, their deck has ample space and is very strong in order to carry heavy, bulky parts and components. Most crane vessels have their own propulsion which is often combined with systems for dynamic positioning (DP). Crane vessels come in various dimensions and crane capacities that far exceed 15,000 t, depending on each offshore project’s requirements.

Note: The pictured model of a crane vessel is used for illustrative purposes only. The crane vessels in the offshore market are similar to the model.
