First Ferries Powered by
In 1985, Mogas designed, produced and implemented a
pilot injection natural gas/diesel fuel system technology for the conversion of
a 350-Ton ferry, the M.V. Klatawa, the first passenger ferry in the world
licensed to operate on natural gas. The engines on board this ferry and its
sister, the M.V. Kuleet, also adapted to use gas, have accumulated more than
600,000 hours of trouble free dual-fuel Natural Gas operation and are saving
the Province of British Columbia an estimated $58,000 per year in fuel and
Aside from the cost benefits, the ferries conversions to
natural gas also provided:
- significant noise reduction. Under natural gas propulsion, the
characteric diesel combustion knock is greatly reduced as combustion in the
cylinders is slower and longer.
- reduced risk of contaminating diesel fuel spills; the
natural gas replaces more than two thirds of fuel, therefore diesel fuel
consumption and its handling is now less than one third.
- engine oil changes extension up to five times, from 150
hours to 750 hours; this has reduced the contamination of disposing or
recycling the old engine oil by 80%.
Natural gas is handled in safe high pressure storage
tanks and tubing and is unlikely to be spilled, however, since natural gas is
lighter than air it is quikly disprsed in the sky.
