The PaxCar ferry VIKING GRACE is the largest LNG fuelled passenger ship. Built in STX Turku yard, the ship is designed for efficient year-round service on the trans-Baltic route linking the southwest Finnish port of Turku with Stockholm.

Financed by the Norwegian Directorate of Public Roads, a car ferry GLUTRA with a capacity of 100 private cars was designed for operation on natural gas, based on a new set of Norwegian safety standards for gas fuelled passenger ships.

With new emission control regulations taking effect, gas as a ship fuel, once banned, is now re-emerging as an environmentally and economically attractive option.

Gas without condensation at common operating pressures and temperatures where the predominant component is methane with some ethane and small amounts of heavier hydrocarbons.

Either the government of the country in which the ship is registered, or the Administration delegated to deal with merchant shipping for that country.

The ODP of a compound is defined as the ratio of the total amount of ozone destroyed by that compound to the amount of the ozone destroyed by the same mass of CFC-11. The ODP of CFC-11 is defined to be 1.0.

These are man-made chemicals which degrade the ozone layer in the upper atmosphere and which are being phased out, both in terms of manufacture and use, in accordance with the Montreal Protocol.
