Drilling contractor Maersk Contractors has agreed with Hyundai Heavy Industries (HHI) to build the second MSC CJ70-150-MC drilling jack-up. This ultra harsh environment jack-up drilling unit is capable of operating in water depths up to 150 m North Sea conditions. Marine Structure Consultants will deliver the basic design package, the fixation system and the hydraulic skidding systems of the new patented MSC X-Y cantilever system.

The fixation systems are being used to fix the legs to the platform. Such fixation enables the reduction of the leg scantlings and/or operations in larger water depth and/or higher environmental conditions. The XY cantilever is a new approach to efficient increase of the loading and reach capacity of the cantilever. The cantilever and drill floor are combined to one structure, which is skidded in both longitudinal and transverse direction. The delivery of this unit is scheduled for end of 2002.
