Subsea Installation

Alfa Lift’s unique combination of a large, submersible main deck and a heavy lift crane offers new opportunities for subsea installation. The crane is prepared for lifts of up to 1,000 mt at water depths of 300 m. A winch with a hand-over system can be fitted to reach deeper. At the same time the deck can be submerged to 13 m (14.66 m inshore) below the sea surface to increase sea state. One or several subsea structures placed on the deck can be submerged to below the splash zone and then be lifted overboard.

Due to the large deck area the vessel is also very well suited to install large mooring systems for oil and gas floaters or floating wind turbine structures.
