Marine Support

J.F. Brennan Company owns one of the largest fleets of heavy marine equipment north of St. Louis and can provide marine support for span switchouts, heavy picks, and salvage operations. We cover the entire length of the Upper Mississippi River and its tributaries but also have a large fleet of portable barges to assist in outlying bodies of water.  In addition to our large marine assets, we have a staff of 100+ ADCI-certified commercial divers who can deploy quickly.  They are knowledgeable about railroad safety protocol and are willing to assist railroads, engineers, and other contractors to every extent possible.  Our dispatch center is open 24 hours per day, 365 days per year, and standing by, ready to help.

Everything we do takes place around the water, and as a result, we have the right people, equipment, and programs necessary to mitigate associated risks. Working off barges with heavy equipment takes a special talent set. Our engineers have specialized training in Naval Architecture Analysis to perform a marine plant stability analysis before any heavy pick.  This analysis is performed specifically for the barge and equipment configuration that is needed for the project.  We also help mitigate risk by having the appropriate levels of insurance coverage for all of our projects, including Marine Pollution Insurance. These measures are necessary to protect the operation and our client during critical times.
