Designed in accordance with the required safety standards of both ABS and DNV GL classification societies, the CJ54 now is a ready solution for contractors and operators wanting to push jackup drilling frontiers.
Having the design classed in advance significantly reduces future risk for all stakeholders and reduces project lead times. For the operator the marketed capabilities have been verified to be incorporated in the design. For the owner and yard the construction risk in terms of design changes and weight are minimized and detailed design can start right away. Moreover, owners can now choose the classification society of their preference without any effects on the Basic Design. The CJ54 is designed to play a competing role in the worldwide arena.
CJ54
The CJ54 opens up a new jackup territory of water depths up to 450ft for worldwide operations. It also is the prime candidate for areas where large leg penetrations occur, due to its high preload jacking capability and available long leg length.
In addition to these advanced worldwide capacities, it can also survive the harsh conditions of the North Sea in up to 110m of water. The innovative and patented X-Y skidding system provides a large drilling envelope of 90x56ft. The CJ54 is a three-legged cantilever type jackup drilling rig, which is positioned in the middle of the well-established GustoMSC CJ series.
The series consists of seven distinct types for moderate and harsh environment designs.
