Brazil's Petrobras halted production on Sunday from its P-40 platform in the offshore Marlim Sul field after a gas leak on the vessel, an oil workers' union and the country's petroleum regulator said on Monday.
The P-40, a semisubmersible production platform, was producing about 45,915 barrels of oil and 800,000 cubic meters of natural gas a day when it was shut down, the union said on its website.
The regulator, known as the ANP, confirmed the shutdown in a statement, adding that no oil or gas was leaked into the ocean. The P-40, located about 175 kilometers off the coast of Rio de Janeiro state, is at the hub of a network of five platforms in Marlim Sul and at the center of Brazil's oil and gas pipelines that interlink undersea natural gas pipelines into a single export line to the coast.
The platform is also linked to an undersea pipeline system that exports oil from the neighboring Marlim field.
The shutdown is the latest in a series of accidents and problems at Petrobras' offshore platforms. It is the second in less than a month at Marlim Sul, which produced 164,000 barrels of oil and natural gas equivalent in April from several platforms, according to Brazil's oil regulator ANP.
Marlim Sul was the sixth-largest producing field in the country in April. The latest problems come a little more than four months after an explosion at a Petrobras offshore field off Espirito Santo state killed nine people and injured 26.
Safety problems in March also forced the temporary shutdown of the P-58 platform in Petrobras' Parque das Baleias field.
