We deliver associated equipment to our proprietary designs, this includes various types of offshore cranes.
The associated equipment for the jacking systems depends on the application of the jack-up.
For truss work legs, the rack and pinion systems are selected. Recently we have enhanced these systems with a better drive system, now using “Variable Speed Drives”. This allows for much smoother operation.
For tubular legs or welded plate legs, hydraulic jacking systems with the pin-in-the-hole principle are applied.
The single acting systems will be used for straightforward robust system requirements. These systems are selected for standard operations whereby lifting speed is not a number one priority.
If there is a lifting speed requirement of over 0.5 m/min, we have developed a continuous hydraulic jacking systems.
Traditionally, GustoMSC has been involved in the design and engineering of large heavy duty offshore derrick cranes, such as the cranes for the Hermod, Balder and DB 101.
Recently a 4,000 ton crane and a 5,000 ton crane have been delivered.
In the lower segment, we have concentrated on pedestal cranes for the wind farm installation market.
These cranes range from 500 to 1,000 tons. Two categories of pedestal cranes can be distinguished: the standard pedestal cranes and the cranes fitted around the leg. The latter have a significant advantage as they have one leg less in their way during lifting operations. Moreover, they create more usable deck space, as the crane is mounted on the jack house.
Among the equipment portfolio we have items such as the leg fixation systems, X-Y skidding systems. More
