The drilling rig will leave Singapore, en route to its first six-year drilling assignment for Petrobras offshore Brazil. The commencement of the operations is expected at the end of July this year.

The company said that West Orion is a sixth generation, high specification, ultra-deepwater, semi-submersible drilling unit. The rig has a high load carrying capacity, an efficient drilling floor layout with improved safety and working environment measures.

West Orion is designed with a positioning system and a water depth capacity up to 3,000mt.

Alf Thorkildsen, CEO in Seadrill Management, said: “This is the third deepwater newbuild delivered to Seadrill that starts a long-term contract with Petrobras. The completion of our tenth new-building project within two years confirms Seadrill’s ability to manage complex projects within time and cost and is a great achievement for our organization and the people involved.

“It also confirms that the Seadrill strategy to order newbuild units with highly reputable yards like Jurong shipyard is paying off.”
