Petrobras 36
Semi-submersible oil platform that sank in 2001
Petrobras 36 (P-36) was at the time the largest floating semi-submersible oil platform in the world prior to its sinking on 20 March 2001.[3] It was owned by Petrobras, a semi-public Brazilian oil company headquartered in Rio de Janeiro.[4] The cost of the platform was US$350 million (currently US$602 million).[5]
The vessel was built at the Fincantieri shipyard in Genoa, Italy in 1995 as a drilling rig. She was owned then by Società Armamento Navi Appoggio S.p.A. The 33,000 tonnes (36,000 short tons) rig was converted by Davie Industry, Lévis, Canada to the world's largest oil production platform.
P-36 was operating for Petrobras on the Roncador Oil Field, 130 kilometres (80 mi) off the Brazilian coast, producing about 84,000 barrels (13,400 m3) of crude per day.[6]
P-36 was replaced by FPSO-Brasil which is a leased vessel from SBM Offshore. The FPSO-Brasil started its lease contract with Petrobras in December 2002. In 2007, the P-52 platform (FPSO P-52) built in Singapore and Brazil came into operation.
