Rack and Pinion Jacking Systems

We have delivered Rack and Pinion systems for jack-up drilling units and well servicing units since the early 1980’s.
Our recent achievement is the introduction of the new generation of Rack and Pinion system with a Variable Speed Drive system.

Hydraulic Jacking Systems

Over the years, we have developed several hydraulic jacking systems for different applications.

- Single acting hydraulic jacking systems are our sturdy, cost-effective system.

Continuous hydraulic jacking systems are the latest GustoMSC development.

Cranes around the leg

Enhancing operations and increasing nett deck area, our latest development is the crane situated around the leg of the jack-up unit. These cranes are supported on the jack-house.

Large offshore Cranes

We have a long track record and many years of experience in the design and construction of these cranes. Reliability and enhanced safety ae key issues.

Pedestal Cranes

The Offshore Wind Turbine Installation market is rapidly expanding, bringing with it a need for dedicated installation units. We have the NG series of wind turbine installation jack-ups available for the market and we add our own cranes. The pedestal cranes for the wind turbine installation units range from 500 tons to 1,000 tons.

X-Y Cantilever System

We developed the patented X-Y cantilever, integrating the derrick and drillfloor to the cantilever. The complete cantilever will skid in longitudinal and transverse direction.

The X-Y cantilever enhances both drilling efficiency and capacity:

- Drilling efficiency as drillfloor and cantilever are integrated
- Capacity as the combined hook load is constant over the hull footprint

Fixation Systems

We added the patented fixation system to our CJ series to improve water depth and environmental capacity. With the fixation system, a rigid connection is created between the truss work legs and the hull.
We deliver the fixation systems to our jack-up units.

Thruster Retrieval Systems

The TRS is one more example of the intelligent equipment solutions that are being offered to the offshore industry. In this system, the standard azimuthing thruster of any reputable vendor is mounted in a specially designed container which also accommodates the thruster utilities. By means of a rack and pinion system this container can be retracted to above main deck level, enabling the drilling unit to perform thruster maintenance on site, even allowing for in-situ thruster replacement.

Equipment

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
