Singapore-based Sembcorp Marine‘s subsidiary Jurong Offshore has secured an $806m contract to design and develop an ultra-deepwater drillship for Sete Brasil.

The new vessel, which is the seventh drillship order from Sete Brasil since February 2012, will be developed based on Jurong Shipyard’s Jurong Espadon drillship design.

Under the contract, all of the drillships will be chartered to Petrobras for 15 years to carry out offshore oil and gas exploration in Brazil’s Santos Basin.

The drillships will feature advanced capabilities and improved specifications to execute deepwater operations around the world.

The vessels will include modern drilling facilities, such as a larger deck area, efficient deck arrangement, dynamic positioning class 3 (DP-3) capabilities and superior motion, as well as a large moon pool for improved drilling operations, according to Sembcorp Marine.

The drillships will accommodate about 180 crews and possess the capability to operate in water depths of up to 10,000ft and drilling to depths of up to 40,000ft.

Sembcorp Marine plans to deliver the seventh drillship in the third quarter of 2016, as part of its overall delivery range scheduled between 2015 and 2019.

Out of the seven drillships to be built at the Jurong Aracruz yard in Estaleiro, Brazil, six will be delivered to Sete Brasil and one to Sete Brasil’s Dutch subsidiary, Guarapari Drilling.

Jurong Shipyard has so far delivered 19 oil and gas exploration, production and storage platforms for Brazilian oilfields.
