A federal judge in Corpus Christi, Texas, has sentenced General Maritime Management (Portugal), the operator of a fleet of tanker vessels, and two crewmembers of the motor tanker Genmar Defiancefor making false statements to the U.S. Coast Guard and failing to maintain an accurate Oil Record Book designed to prevent pollution of the world’s oceans as required by United States and international law, the Justice Department announced.

The court sentenced General Maritime Management (Portugal) LDA, last Friday, to pay a $1 million fine. In addition, the company was sentenced to serve five years of probation. Special conditions of the probation require the company to rehire the whistleblowers if they reapply for employment; submit monthly reports, under oath, regarding compliance; and allow a court appointed official to perform three audits of each vessel and three audits of its shore side office during the probation period. Violations of the terms of probation could result in one or more of the company’s ships being banned from U.S. territorial waters during the term of the probation.

Chief Engineer Antonio Rodrigues was previously sentenced for the same violations on February 10, 2009, to three months of confinement in a half-way house, a $500 fine, a special assessment of $200 and five years of probation. First Engineer Cavadas was likewise sentenced on February 10, 2009, to six months of confinement in a half-way house, a $500 fine, a special assessment of $200 and five years of probation.

During the hearing, the court awarded $250,000 to the five whistleblowers to be divided on a proportional basis for their actions and cooperation.

The company and two crewmembers were found guilty on all counts by a jury on November 25, 2008. The trial and sentencing were presided over by the Honorable Janis Graham Jack, U.S. District Judge for the Southern District of Texas.

Engine room operations on-board large oceangoing vessels such as the GenmarDefiance generate large amounts of waste oil. International and U.S. law prohibit the discharge of waste oil above 15 parts per million oil to water; which can be achieved by the proper operation of an oil-water separator. The law also requires that all of the oil transferred onto, off of, or between tanks within a ship be recorded in the Oil Record Book so all the oil on a ship can be accounted for when the ship is inspected by the U.S. Coast Guard and other port state control authorities around the world.

The criminal convictions were related to events occurring on board the GenmarDefiance during a voyage to Corpus Christi in November 2007. On November 24, 2007, engine room crew members were directed by First Engineer Cavadas to assist in hooking-up a flexible hose between the ship’s bilge pump and the overboard discharge valve bypassing the vessel’s pollution prevention equipment — its oil-water separator — and allowed crewmembers to pump the contents of the bilge tank directly into the Straits of Florida and the Gulf of Mexico.

Further, on November 26, 2007, one of the crew members working in the ship’s engine room was ordered by First Engineer Cavadas and Chief Engineer Rodrigues to assist in connecting a hose from the vessel’s fresh water supply to the oil content meter on the ships oil-water separator. The connection allowed the engineers to “trick” the oil content meter and prevent it from shutting a valve that would re-circulate oily water to the bilge tank where it would be treated through the oil-water separator before being discharged overboard. By tricking the oil content meter, the oily water was permitted to be discharged directly overboard in violation of international law. Two engine room crewmen secretly photographed the illegal connection and provided the photographs to the Coast Guard during a boarding of the vessel on November 28, 2007, while the GenmarDefiancewas docked at the Valero refinery.

This case was investigated by the U.S. Coast Guard, and the Environmental Crimes Task Force, which includes the U.S. Environmental Protection Agency, the Texas Commission on Environmental Quality Investigations Division, and the Texas Parks and Wildlife Department. The case was prosecuted by the Justice Department’s Environmental Crimes Section.
