Jurong Shipyard, a subsidiary of Sembcorp Marine, has awarded a contract to Wärtsilä for the supply of main generating engines and thrusters for six new drill ships.
Wärtsilä will equip each ship with six 16-cylinder Wärtsilä 32 main generating sets and FS3510/NU underwater de-mountable thrusters, with delivery scheduled for 2013.
All six drill ships are being built at the Jurong Aracruz yard in Estaleiro, Brazil; five will be delivered to Sete Brasil and one to Sete Brasil’s Dutch subsidiary Guarapari Drilling.
The drill ships are scheduled to be delivered between the second quarter of 2015 and the second quarter of 2019.
Upon delivery, all six drill ships will be chartered to Petrobras for 15 years; three will be operated by Odfjell, while the remaining three will be operated by Seadrill.
Wärtsilä Ship Power vice president Magnus Miemois said that the reliability, efficiency and performance of the systems is important for drill ships that operate in very deep waters and face challenging operational conditions.
"At the same time, environmental issues are a priority for the owners and operators of these ships, and again Wärtsilä’s track record in this field is second to none," Miemois said.
Jurong Shipyard awarded a contract to Aker Solutions in August 2012 to deliver drilling equipment packages for the six drill ships.
Under the deal, Aker is responsible for providing complete topside and subsea equipment packages for the drill ships, with an option for one further unit.
Earlier in August, Sembcorp Marine won a $4bn order from Sete Brasil to design and build five drill ships, which follows a $792.5m agreement in February 2012 from Sete Brasil’s Dutch subsidiary Guarapari Drilling to build an ultra-deepwater drillship.
All six drillships will be based on Jurong Shipyard’s Espadon drill ship design for deepwater operations around the world.
Each vessel will be equipped with modern drilling facilities, a large 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.
With the capacity to carry 180 people each, the drill ships will be capable of operating in water depths of up to 10,000ft and drilling to depths of up to 40,000ft.
