Cruise ship giant Carnival Corporation announced Thursday it has signed yet another shipbuilding contract for a second LNG-powered cruise ship for its P&O Cruises brand with leading German shipbuilder Meyer Werft.

The next-generation newbuild is scheduled to be delivered in 2022.

Similar to a P&O Cruises sister ship due for delivery in 2020, this second new vessel will be the largest cruise ship to be built specifically for the British market. It will be 180,000 gross tons and will accommodate approximately 5,200 guests (lower berths). Both new ships will be registered in the UK.

The newbuid is part of Carnival Corporation’s aggressive fleet expansion strategy with 19 new ships scheduled for delivery between 2018 and 2022 to keep pace with the growing demand for new capacity....

LNG won't even ignite, let alone explode.

First you have to raise the temperature from the -260°F that keeps it a liquid.  It has to gain enough heat to become a gas. 

Then the gas has to be diluted with air down to 15% concentration before it can ignite to burn.  If it goes below 5% concentration it won't ignite again.

All at the same time, the gas is significantly lighter than air, so it is rising up and away from the ship.

The danger is a leak inside a room that traps the gas in sufficient concentration.  A vent at the top of the room will let gravity prevent the accumulation.
