Mid-Atlantic Coatings is an environmentally conscious marine blasting and coating contractor that utilizes an innovative approach to surface preparation and preservation. The company holds the blasting and coating contract for the midlife refueling and complex overhaul (RCOH) of the USS George Washington in progress at Huntington Ingalls Industries Newport News Shipbuilding division. BARTON supplied over 6,000 tons of garnet used on the project including a new abrasive, 30/60 CG ADIRONDACK garnet.
The aircraft carrier arrived at the Newport News shipyard in August 2017, but project planning started more than two years earlier. Under MAC’s leadership, two teams of equipment representatives and manufacturers were formed — a surface preparation team and a preservation team.
“These teams included competitors who worked as partners to assist throughout the planning and execution phases,” said Vincent D’Auge, president of MAC. “The goal was to work together in the development of new processes as well as enhancements to existing methods with the priority of improved environmental and health safety on the job site.”
The MAC surface preparation team identified vapor blasting technology as one means to accomplish this goal and successfully introduced this blasting technique to Newport News shipyard. The first blast on the underwater hull and freeboard was executed using equipment supplied by Massachusetts based Greener Blast Technologies operated with BARTON garnet abrasives. This method reduced abrasive consumption, reduced dust levels, improved worksite visibility and enabled MAC to blast near adjacent work.
The second milestone in surface preparation at the shipyard was the use of garnet for the dry blasting. Traditionally, coal slag was used for repair work. BARTON representatives worked closely with MAC to prove that pure, low dusting BARTON garnet would effectively and safely meet the project requirements.
Engineered specifically to meet the needs of this project, 30/60 CG ADIRONDACK garnet was first produced in January 2018.
“30/60 CG is produced at our mine in the Adirondack Mountains of New York state,” said Randy Rapple, president of BARTON International. “We are honored to have this opportunity to support MAC and the U.S. Navy by supplying our American garnet for the refurbishment of the USS George Washington.”
The award was presented at SSPC's 2019 Coatings+ annual conference in Orlando.
