Dunkerque LNG's commitments to safety are applied at every step: from Liquefied Natural Gas (LNG) transport all the way to storage.
LNG transportation is ensured by methane tankers designed according to very precise safety standards, among them:
- reinforced hulls and double-walled storage tanks;
- an insulating coating that limits evaporation of the gas;
- very sensitive leak monitoring and detection devices;
- regular trainings and refresher courses for the crew.
Access to the boats from the port also follows strict regulation based on several studies (nautical risks, navigation, traffic and hydraulics) to ensure that methane tanker navigation takes place under optimum safety conditions.
After the ships dock, the LNG is unloaded with a highly secured pumping system:
- a minimum of intervention;
- at least two people present in addition to surveillance by instruments, detectors and cameras in the control room;
- unloading stops if the vessel moves unexpectedly during this phase.
The LNG is then stored in a heavy-duty steel reservoir covered by reinforced concrete. This tank was designed to be resilient in the case of natural disasters, accidents or malevolent acts.
Other checks and security standards have been established, in particular those linked to fires from leaks:
- emergency plans (internal operations plan, external emergency services…);
- firefighting equipment (fire pumps, water curtains, water cannons…);
- continuous monitoring of facilities thanks to control mechanisms as well as process and site monitoring screens.
