Trinity Marine Products Inc. said it will shut down its Brusly plant beginning on Halloween, a move that will put 288 employees out of work after it announced then reversed a similar layoff.

Two other companies also announced layoffs Tuesday: Bradken's Amite foundry and ProActive Technologies Inc., which lost a military contract in northwest Louisiana.

According to a notice filed Aug. 31 with the Louisiana Workforce Commission, Trinity said all barge production and administrative tasks will shut down by Dec. 9.

Trinity Marine Products makes dry-cargo and tank barges used on rivers and other inland waterways, according to the company’s website. The barges are used to move products that include grain and coal, and aggregates or petroleum, fertilizer, ethanol and chemicals. The company has been hard hit by low crude oil and coal prices.

Trinity issued a similar warning in August 2015. At the time West Baton Rouge Parish President Riley “Pee Wee” Berthelot Jr. said they were regular occurrences. “Trinity has done that several times over the years .... Usually it will shut down a while, but they usually always come back,” he said. “And I hope that’s what will happen again.”

Berthelot’s hopes came true. In October 2015, the company said it got a contract that would save the Brusly jobs, about three weeks before the first layoffs would begin.

Bradken said it will shut down its Amite foundry beginning Oct. 26, a move that will put up to 65 employees out of work. Bradken, which makes products for the mining, freight rail, oil and gas and power industries, is consolidating work at its other foundries. In North America, the company has foundries in Washington, Kansas and London, Ontario.

ProActive Technologies Inc. said it will lay off 51 employees at its Barksdale Air Force Base location, after the company lost its contract to provide logistics support for the B-52 bomber’s training system. The layoffs are set to begin on Halloween.

ProActive noted it expects the majority of employees to be hired by the company that took over the contract with the Air Force.
