DNV delivers report on Gulf spill

Norwegian classification society Det Norske Veritas (DNV) has delivered a report to the US government on the Deep Water Horizon oil spill in the Gulf of Mexico, and reportedly has pinpointed the cause of the oil platform’s blowout last year.

DNV, which specializes in maritime risk management services and research, is expected to conclude that a cutting mechanism in the ventilation system failed to seal the borehole because a piece of piping became stuck in the mechanism.

DNV was brought in to investigate the issue after the disaster in April 2010, which killed 11 workers and set off a much-publicized oil leak that lasted for five months.

The Norwegians have been examining the 300-tonne installation at one of NASA’s facilities in Louisiana since August. The final version of the report will be made public in the summer.
