SEA-2000 Jack-up

Safe, Solid, and Stable Platform, Year-Round Operations


Wind Maintenance and Field Lifecycle

The SEA series are multi-purpose jack-up barges, used for offshore support and maintenance, and civil construction works. They are specifically designed and built to operate in moderate and harsh environments.

The SEA-2000 is intended for use in water depth up to 30 m in a North Sea type rough environment, up to 40 m in a moderate environment, and has a leg length under the hull of max. 63.7 m. The four legs and the diagonal preloading allow for easy, fast, and secure jacking and preloading operations. The units are characterized by optimized variable load, deck area, and flexibility for adding all types of mission equipment.

The SEA-2000 is a medium to large-sized, multipurpose jack-up. It can be equipped with a pedestal crane of up to 400 t. It offers a large open deck space for temporary auxiliary equipment or accommodation blocks for up to 150 POB. The unit is suitable for wind turbine support works in the mid-water depth range and installation works for the smaller turbines.
