Noble Globetrotter I & II
The innovative Noble Globetrotter drill ships, based on the HuisDrill 10000 design, represent a true step change in the construction of ultra-deepwater drill ships. The vessels offer improved operational efficiency due to the different equipment layout. Designing both vessel and equipment allows for optimisation of the entire drilling unit. The result is a more compact drilling vessel.
The design is possible because of three radically different features, namely:
- hoistable floor;
- engine rooms under the accommodation.
The DMPT has no V-door limitations and a small footprint. It is possible to skid the BOP underneath the floor when it is hoisted and then lowered on the construction side. The BOP is then skidded from the aft to the forward well centre by means of a skid cart that moves along the moon pool under the substructure.
