Efforts to reduce emissions from ships – including stricter regulations about marine fuels’ allowable level of sulphur – are curbing the use of heavy fuel oil (HFO) in the marine shipping industry.
Fuel lifecycle climate warming impact. When comparing the CO2-equivalent emissions of different fuels per 1 tonne of cargo transported 1 km by ship, the climate warming of LNG exceeds that of heavy fuel oil when the amount of methane slip from LNG use is greater than approximately 1% of the volume of LNG.
LNG & Marine Shipping: LNG ships are made with many safety features. These include insulated tanks and double hulls. The LNG tanks can be rectangular or round, spherical in modern LNG carriers.
The lifecycle of LNG involves extraction from the ground, removal of impurities and gases and then it is shipped through a pipeline to a liquefaction facility and stored in an LNG tank for shipping. It’s processed upon arrival.

Double hulls are a preventive measure implemented to reduce the risk of ship-source pollution in the marine environment.
There are many primary sources of underwater noise that affect marine mammals including commercial vessels, cracking ice, surface waves, earthquakes, marine life, storms, rain, pile driving, sonar, recreational vessels, seismic survey, snowmobiles, sonar and hydrothermal vents.
When a vessel is damaged, disabled or otherwise in distress at sea, finding a place of refuge – a place where it can be taken to prevent further damage to the vessel or pollution to the environment – can be critical.
