Brazil-based QGOG Constellation has exercised an option with South Korean shipbuilder Samsung Heavy Industries for a drill ship.
The option has been exercised through one of QGOG’s subsidiaries; it will be the third drill ship the company has ordered with Samsung Heavy.
The drill ship, scheduled to be delivered in December 2014, will be equipped with advanced technology to undertake deepwater drilling work.
The DP3 ultra-deepwater drillship will be capable of carrying out drilling work up to a water depth of 12,000ft and a vertical drilling depth of 40,000ft.
Based on Samsung Heavy’s 12000 hull design, the drill ship will be equipped with a modern dynamic positioning system and a complete dual activity hoisting system along with enhanced client and third-party facilities.
The drill ship will be equipped with six 5.5MW thrusters for enhanced station-keeping, five mud pumps and seven shale shakers.
A larger engine and thrusters, as well as advanced technology in the ship, will help maximise station-keeping capability during drilling operations.
The drill ship has been designed to operate under 6.8m wave heights, 26m/s wind speeds and 1m/s current speeds.
Equipped with an advanced 15k psi subsea well control system with seven rams BOP, the drill ship will be designed for capping oil spills from damaged deep-water wells.
The drill ship will also have an expanded space for drilling fluids and bulk capacity, with the ability to carry a payload of more than 20,000t.
A 165t active heave compensating crane will allow the drill ship to be used for the deployment of subsea production equipment without interfering with other ongoing drilling operations, QGOG said.
The new drill ship will add to QGOG’s fleet of 11 units, including eight under-construction ultra-deepwater rigs.
