When you consider the higher maintenance cost of a diesel, and its need for expensive lubricating oil, the difference becomes even more staggering.
Small wonder that coal is
The boilers will power a 665-foot vessel with each supply- ing 48,000 pounds of superheated steam per hour at a temperature of 900F and operating at a pres- sure of 870 psi. Only proven state-of-the-art technology is used and the fuel is readily avail- able coal.

Of course, we're not new- comers to marine coal power.
Our last coal-fired boilers which were launched on the Great Lakes in the 1950s are still in operation today. And now, once again we're offering significant coal-based fuel savings at sea.
After all, when you can save a million here, a million there, it
