Five people remain in stable condition in a hospital, the rig's Norwegian owner BW Offshore told Brazilian media, after the February 11 explosion that the oil workers' union said was caused by a gas leak, although investigations are ongoing.
The rig operates in the Camarupim field around 120 kilometers (75 miles) off Brazil's southeastern coast and had daily average production of 2.25 million cubic meters of natural gas and 2,200 barrels of oil in December.
