Foss to take delivery of new autonomous tug May 7, 2021, by Fatima Bahtić A Seattle-based tug and towing company Foss Maritime has joined forces with autonomous vessel software and systems provider Sea Machine Robotics to integrate autonomous systems on a tugboat set to deliver this month. The tugboat, named Rachael Allen, is the fourth of several new ASD-90 tugs under construction at Nichols Brothers Boat Builders, in Freeland, Wash. According to Foss, the 90-ton bollard pull tug will be the first U.S.-Flag harbor tug to integrate autonomous systems in real-world commercial operations. The project also marks Sea Machines’ first installation of an autonomy system on a vessel over 5,000 hp.
