29 tugs in panama canal with mix mostly 12v228 (FDL) engines
Next contract of tugs at panama canal has been dragging for years so I have no idea if the trend of GE engines for Canal authority will continue.
Crescent towing, Reinauer transportation, kirby, Hyak, Oceaneering, Harley Marine ATB’s, Harvey gulf, Manson construction, Week Marine, Washington state ferries, TxDot, ECO, all have at least a couple vessels with GE engines.
