In a statement the company said, “[Our] jack-up rig Trident 20 suffered damage on July 3 from a fire in the rig’s engine room while operating off the coast of Turkmenistan in the Caspian Sea. There were no injuries resulting from the incident and the cause of the fire is under investigation. Trident 20’s crew has been reduced to just essential personnel.”

“The rig, known locally as ‘The Gurtulush’, has been operating under a three-well contract with Malaysia’s Petronas since April 2004 [and] the contract was expected to expire this December, subject to extension options. Petronas intends to suspend the contract, allowing time for repairs,” it added.

Transocean expects repairs on the rig to take between two to three months to complete.
