As an old single-screw tug man who's learned the modern art of maneuvering a tractor tug, I'd love running this thing. At times long in the past, I've run older, high-hour Diesel boats that smoked a lot (I remember one Pilot who called for me to "cut 'er back!" when the tug I was running almost smoked him off the bridge wing!) He'd never have to worry with one of these.
LNG is not only a cleaner fuel, but it's currently cheaper, too. I think we'll see more LNG powered tugs coming, to join the LNG powered OSVs and ships that are starting to appear.
Do you work on an LNG powered vessel? I'd love to hear a description of your experience or see photos - see my Contact Me page. Thanks!
