Nido said the development of Typhoon 07W Fengshen to the east of the Philippines halted progress on the remaining commissioning work needed for first oil production.

Typhoon Fengshen was rated a category three typhoon at its peak and passed within 150km of the Galoc field, according to the company.

The floating, production, storage and offtake vessel Rubicon Intrepid was disconnected from the mooring and riser system on Saturday due to worsening sea conditions, the company said.

"Reconnection of the FPSO will occur as soon as there has been a sufficient reduction in sea state at the field location," Nido said.

"Current weather forecasts predict this to be unlikely before Friday, June 27, and this will be monitored closely over the coming days.

"Once reconnection has been made, a full systems safety and integrity check will be undertaken prior to first oil production."

Galoc is expected to start producing more than 15,000 barrels of oil per day.

Nido has a 23% stake in Galoc while Otto Energy has an 18.28% indirect stake in the project.

Other members of the consortium are Alcorn Gold Resources, Forum Energy, Oriental Petroleum, PetroEnergy Resources and Philodrill.
