An oil platform was partially evacuated after it began to list early Friday off the coast of the southeastern Brazilian state of Rio de Janeiro, officials said.

The platform, which provides service to state-controlled energy giant Petrobras, was subsequently stabilized and apparently is not at risk of sinking, the company said.

The SindiPetro-NF oil workers' union said a 113-person crew was on board the rig, owned by Noble do Brasil, when the vessel started to tilt at around 1:00 a.m. in the Campos basin.

Most of the workers were moved to another platform.

In 2001, 11 Petrobras workers were killed in a series of gas explosions on a giant floating oil platform that was producing around 84,000 barrels of crude per day in that same basin.

The vessel subsequently sank. EFE
