Configuration
The platform consists of a number of standardized floating modules coupled together through a male / female connection system. The platform is supported by four spud legs in heavy duty spud wells. The hydraulic power unit with control cabin on top is located on the platform, with actual location on the platform being flexible.
Modular design
All platform components are sized to be easily transportable by road, rail or sea. Due to the modular design, overall dimensions and spud legs length can be adapted to customer needs.
Jacking System
The jacking mechanism consists of two hydraulically operated crossheads per spud well, to lock and unlock the spud for vertical movement. Vertical movement is accomplished by four hydraulic heavy duty cylinders with a stroke of 1.22 meter, working on an operating pressure up to 250 bar.
The four spud wells are powered by a hydraulic power pack for simultaneously lifting and lowering the spud legs through its seating. The powerpack is built in a 20’ container approved for the offshore environment.
The powerpack consists of two diesel engines powering two hydraulic pumps. The double execution also guarantees redundancy in case of emergency. The system is operated from a central control system with complete remote PLC control of the jacking operation. For safety reasons and as back-up, full manual and local control at the spud wells is also possible.
