Seatrium AmFELS plans to lay off 91 workers at its Brownsville shipyard starting Nov. 28, the company told Texas regulators in a notice required under the Worker Adjustment and Retraining Notification Act. 

Most of the jobs are in skilled trades, including welders, mechanics, pipefitters, electricians, and crane operators. A smaller group includes administrative staff such as accountants and clerks, according to the notice. None of the affected employees belongs to a union.

“All impacted employees have been notified individually and provided with resources to assist in their transition,” Ashley Velasquez, the company’s human resources manager, wrote in the WARN letter.

Seatrium AmFELS did not say how many employees will remain after the cuts, and the company declined an interview request about its plans.
