Onboard the Vessel shall be arranged drilling support facilities such as bulk handling, storage and mixing, mud storage in tanks and pits, high pressure mud pump equipment, well cementing capacity, pipe and tubular storage and remote drilling control and monitoring system.

Furthermore the Vessel will provide office facilities, accommodation for up to 140 persons, helicopter landing facilities and life boat rescue arrangement.
