Many MRG companies provide harbor services, offering tug operations within harbors including vessel assist, escort and fuel bunkering. Marine Resources Group focuses these activities in the Pacific with Foss, AmNav, and Hawaiian Tug & Barge, where the company holds large market shares on the West Coast and Hawaii. MRG is now focused in Massachusetts as well, through the Foss Atlantic Division. Our companies provide a fleet of tugs with up to 8,200 horsepower that can safely dock or escort the largest vessels. We continue to design, build and employ tractor tugs that are at the leading edge of technology in the industry. Our large fleet of petroleum barges, including newly-added double-hull barges, offers ship-bunkering services in major ports along the U.S. West Coast.
