The next generation of drillship
Brand new overall concept(e.g. drilling without tower)
Partial Modification of the
concept(e.g. new type of drilling tower which
requires new practices to operate)
Overtaking dualism
between Hull and Drilling
System
CONSOLIDATE ABILITY TO PERFORM IN UDW

Figuring out product categories
Driven by the changing of theboundary conditions
INNOVATION
Mainly building new rigs whensupported by a multy-years contract
CONSERVATISM
Specialized rigs designed for givenenvironment, performances,operative regions, rules, local policy
CUSTOMIZATION
Big volumes, wide market
Stable boundary conditions Granted market, low risk
STANDARDIZATION
(1) Jack ups are not considered; fleet includes confirmed new orders
