BREWER, Maine — The final load of oil refinery modules manufactured in Maine is leaving for Texas.

A barge loaded with seven of the modules is scheduled to depart Friday from Brewer for the 2,300-mile journey to the Gulf of Mexico. In all, the Cianbro Corp. Eastern Manufacturing Facility in Brewer built 51 of the steel modules for the Motiva Port Arthur Refinary in Texas, which is undergoing a $7 billion expansion.

The Bangor Daily News says the modules have to be transported by water because they are too big to travel by road or rail. The modules can be up to six stories high and weigh as much as 700 tons.

The Brewer plant employed about 500 people at its peak.
