A company that services oil platforms in the Gulf of Mexico falsified safety inspection reports before and after 2012 platform fire that killed three workers will pay $9.5 million in fines.

On Thursday The US Justice Department announced that Wood Group PSN will pay a total of $7 million for falsifying safety inspection reports performed on its Gulf of Mexico facilities over several years.

The Wood Group will also pay an additional $1.8 million in fines for spilling oil into the Gulf of Mexico after a platform explosion in 2012 that killed three of its workers.

The Wood Group is also ordered to pay $700,000 for community service projects.

When the explosion occurred in 2012, workers were on the platform preparing it to go back into producing oil.

It was later determined by investigators that oil vapors were ignited by welding the morning of November 16, 2012, that led to the explosion.

Avelino Tajonera, Elroy Corporal, and Jerome Malagapo  were killed in the blast. Several other workers were seriously burned or otherwise injured.

Federal documents showed that from April 2011 to July 2014, employees at Wood Group PSN’s Cameron, La., office failed to inspect and maintain facilities that they were contracted to oversee in the Gulf of Mexico. They also falsely indicated that the facilities had been properly inspected and maintained.

Last April some of the most serious charges – manslaughter and criminal violations of the Clean Water Act – were thrown out by a federal judge in the Eastern District of Louisiana district court. The government has since appealed to the Fifth Circuit in a bid to have them reinstated.

In a news release from Feb 23rd, the Wood Group acknowledged 87 violations on the offshore platform.

Wood Group admitted its employees were negligent in the way they authorized welding to be done on West Delta 32, and that communication lacked between personnel on the platform, including Wood Group PSN’s person-in-charge, Christopher Srubar, contributed to the events that caused oil to be discharged into the Gulf of Mexico in a harmful quantity.

“We deeply regret these incidents occurred and we cooperated fully with the government and relevant regulatory bodies throughout both investigations,” Wood Group said in an emailed statement
