Self-elevating Platforms
We designed and built the first civil construction self-elevating platforms - named Kraanvogel and Lepelaar - in 1969. Many self-elevating platforms have been built since, for a variety of activities. Most platforms are operating in coastal or sheltered waters to support offshore civil construction works.
SEA series
In the late 1990’s we developed a cost effective unit which we dubbed the SEA series. This series has a large usable deck area, simple tubular legs and sturdy GustoMSC “pin-in-the-hole” hydraulic jacking systems. The units are non-propelled to reduce building costs. Typically these units operate in water depths of between 20 and 45 m.

NG series
For the offshore construction, maintenance well servicing and installation markets, GustoMSC has developed the proprietary NG class of units. The NG class has been introduced for situations where mobility, self-powered propulsion and positioning at the jack-up location are the leading prerequisites for efficient use. The streamlined barge shape allows a sailing speed of up to 10 knots at full draft. The thruster system (which can be an all azimuthing system or a combined system of azimuthing thrusters and bow thrusters) enables controlled positioning with often a DP2 class notation. As it has its own propulsion, the unit is independent of the availability of tugs and its operational envelop is enhanced with more workable days.

Wind Turbine Installation Vessels
A continuation into the Wind Turbine Installation market is the next phase in the GustoMSC NG series. The installation of offshore wind turbines requires dedicated vessels with specialized equipment and high variable load capacity.
Examples of GustoMSC units in operation are the MPI Resolution and Wind Lift I. As the installation contractors have their own requirements GustoMSC developed a range of suitable solutions. Besides the proprietary design, we deliver the jacking systems (hydraulic jacking systems or rack and pinion systems), the specialized cranes (pedestal or “wrap around the leg”) and handling tools (upending frames, rotation equipment).
