Gas Certificates

Marine fuel may be obtained from petroleum distillation or either distillate or a residue. In general terms heating oil is any liquid fuel that's burned during a furnace or boiler for the generation of warmth or utilized in an engine for the generation of power, except oils having a flash point of roughly 42 °C (108 °F) and oils burned in cotton or wool-wick burners. Fuel oil is formed of long hydrocarbon chains, particularly alkanes, cycloalkanes, and aromatics. The term heating oil is additionally utilized in a stricter sense to refer only to the heaviest commercial fuel which will be obtained from petroleum , i.e., heavier than gasoline and naphtha. Small molecules like those in propane and naphtha and gasoline for cars and jet fuel have relatively low boiling points and that they are removed at the beginning of the fractionation process. Heavier petroleum products like diesel oil and grease are much less volatile and distill out more slowly, while bunker oil is literally rock b...

Gas is denser than air, so in the case of a leak, it will make its way to the lowest point i.e. the bilges where it'll stay until the boat is aired to clear it or something ignites it, which may end in a big explosion. Although LPG is potentially hazardous, it is often used quite safely if the equipment is correctly installed, well maintained, regularly inspected for damage and used carefully. Gas bottles should be stored upright during a dedicated locker which drains overboard (to help prevent gas ending up within the bilges). The drain should be checked regularly for blockages, for instance by squirting a hose quietens the drain. For boats which weren't manufactured with a fanatical gas locker, finding appropriate stowage for the gas bottles are often difficult. However, this needs to be done carefully to prevent accidental damage and should not be in a position which would allow leaking gas to enter the interior of the vessel i.e. located too close to hatches. Most boats als...
