In fact, the push to LNG by Europe is real: The Continent is out of oil but well- supplied by natural gas and U.S. re? nery products. Europe’s port cities strive to be carbon-free harbors that nevertheless give free reign to LNG supply barges or
LNG-fueled cruise ships. Marine fuel and emissions are being strictly moni- tored, with the monitoring technology offered up by classi? cation societies.
For over two years, now, MARPOL Tier
III nitrogen oxide rules have been in ef- fect for vessels with engines equal to or greater than 130 kW, and new Emissions
Control Areas and the 2020 (or 2025) 0.5-percent sulfur cap are on the way.
Since the preponderance of tugs already operate in current or future near-shore
ECAs, they face widening compliance issues (as in the waters around Europe’s many LNG import terminals and two
LNG export terminals at Hammerfest
LNG in Northern Norway and Yamal
LNG in the Russian Arctic).
The Arctic — sensitive, likely future

Europe of these LNG types. The ves- sels, designed by Robert Allan, won’t need to respond to quite the same arctic conditions as tugs plying, say, Yamal or
Northeastern Quebec, but they do need to respond to remoteness, freezing mists and fast shipping. To power that pre- paredness, they have Wärtsilä LNGPacs of two, six-cylinder, 34DF engines of- fering “seamless” LNG-diesel use and 3,000 kW each. Like every vessel in the
Norwegian arctic, they have assigned roles in area oil-spill defense: onboard oil skimmers and booms; a RIB for arctic rescue and comfort for eight. The third of this trio of 40-meter tugs — Audax,
