The U.S.’ first linehaul towing vessel powered by Tier 4 Caterpillar high-speed engines with selective catalytic reduction( SCR) was built by Blakeley BoatWorks (BBW) and is now operated by Cooper Marine and Timberlands (CMT).
In March 2021, Blakeley BoatWorks completed construction of M/V Gretchen V. Cooper, a state-of-the-art, Tier-4 inland linehaul tow boat. This 3,400-horsepower vessel is 110-feet long, 33-feet wide, and expands CMT’s fleet to 20 vessels.
Currently, Tier-4 diesel engine standards are the strictest U.S. Environmental Protection Agency (EPA) emissions requirements for new engines found in inland marine vessels.
