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

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
