In a commitment to significantly enhance services to its customers, and to expand its ship-assist capabilities at California’s largest ports, AMNAV Maritime Services will construct four new tugs that will be among the most powerful in the marketplace. The multi-million dollar fleet expansion was announced by Milton Merritt, president of the company that is already a major provider of ship-docking services on San Francisco Bay and at the ports of Los Angeles and Long Beach. “Through this investment, we will be both growing and improving our presence in the ship-assist sector,” said Merritt. AMNAV, part of Seattle-based Marine Resources Group (MRG), will build the new tugs at an MRG-owned shipyard in Rainier, Oregon.
