Liquefied natural gases (LNG) -marine transport & accidents in LNG tankers
Liquefied natural gas (LNG) compresses to a small
fraction of its original volume (approximately
1/600) under liquefaction. With the amount of flammable material that LNG contains, it has the potential to be an extremely dangerous chemical, if handled improperly. The liquefaction of natural gas
raised the possibility of its transportation to many destinations.
The LNG fleet delivers more than 110 million metric
tons annually to ports around the world. Accidental spillage of liquefied natural gases are rare with no significant cargo losses. . This safety record is
attributable to continuously improving tanker technology, tanker safety equipment, comprehensive
safety procedures, training, equipment maintenance,
and effective administration oversight.
The most severe accident that may realistically occur
to a loaded LNG tanker is the breach of one or more
storage tanks, with consequent discharge of liquefied
natural gas outboard. No accidents leading to loss of
cargo have occurred over the history of maritime liquefied natural gas transportation. This safety record
is at least partially due to the double-hulled construction of LNG tankers and the separation between the
LNG cargo tank and the inner hull, which effectively
makes the cargo tank's wall a third safety barrier to
transitions are physical explosions caused by
rapid vaporization of liquefied natural gas that
do not involve combustion or burning. When
liquefied natural gas flows on water, it forms a
thin vapor film that separates it from the water.
In locations of vigorous mixing, this film can be
breached and LNG can come into direct contact
with water. Under those conditions the LNG can
undergo rapid evaporation, causing a rapid
In past spill experiments, rapid phase transitions
have been observed at the first point of mixing with
water and at the leading edge of a spill.
known to be the most vigorous at these two locations. Rapid phase transitions are much less energetic than combustion explosions. Unconfined rapid
phase transitions are generally not considered hazardous; however, these can cause structural damage
if they were to occur in a confined space.
