Mitsui E&P Australia Pty Ltd, part of the Mitsui trading group, has a 40% stake in the Vincent Oil field.
The vessel is owned and runned by Maersk Group on behalf of the partners and Maersk had said the structure was still intact, according to Woodside Petroleum.
It was generating an out put at an annual rate of 35,800 barrels of oil per day for the year-end 2008, a Woodside spokesman said.
An investigation team has landed on the Maersk Ngujima-Yin to begin assessing the damage from fire on board the floating production storage and offtake facility.
