Typically LNG ships are up to 290m long and constructed to stringent international standards. They are equipped with a comprehensive range of safety equipment, emergency shutdown systems and fire and gas detection systems. These carriers are also subject to international security and safety codes.
ConocoPhillips is a member of the Society of International Gas Tanker and Terminal Operators Ltd, which provides international criteria for best practices and standards for LNG shipping.
LNG weighs less than half the weight of water so it will float if spilled on water, before quickly evaporating and dissipating into the atmosphere, leaving no residue. If LNG were to spill, the environmental cleanup would be minimal to non-existent.
