A worker off Malaysia has tested positive for Covid-19, the second such confirmed case in Southeast Asia’s second largest oil producer.

“Petronas, through its subsidiary, Petronas Carigali, confirms that one of its contractors at an offshore platform in Miri, Sarawak has tested positive for Covid-19. The contractor is currently receiving treatment at a government hospital,” Petronas told Upstream on Monday.

A contractor source claimed that the worker in question was a rig crew member on Velesto Drilling’s jack-up Naga 6.

As a result of his diagnosis, work has been temporarily stopped at Petronas Carigali’s Tukau Timur (East Tukau) and Baronia fields’ infill drilling programmes.

“As a precautionary measure to manage the risk of exposure, we have temporarily locked down the rig and suspended all crew change. All identified close contacts have immediately been placed under quarantine for 14 days,” said Petronas.

“We are working closely with the Ministry of Health to manage the Covid-19 outbreak. We would like to ensure that all our businesses operate in a safe manner and in adherence to the ministry’s guidelines,” added Malaysia’s national oil and gas company.

“Our utmost priority and concern for now is the safety and health of our employees, contractors and surrounding communities in our areas of operations.”

Naga 6 rig owner Velesto Energy in Kuala Lumpur did not respond to requests for comment.

The Naga 6 is one of four of Velesto’s premium jack-up rigs currently working for national upstream company Petronas Carigali in Malaysian waters.

The Naga 2, 3, 5 and 6 rigs are all on firm one-year contracts due to expire in April. Each of these contracts comes with two 12-months options.
