It’s a real word, but inappropriate in this context. Liquefaction is what the article describes, liquification would be actual melting of the cargo.

If your nickel-ore dry bulk cargo is undergoing that kind of liquification, your ship will likely also be experiencing adverse handling.

My guess is the submitter just typed the headline from memory and made an intuitive noun form of "liquify," which in typical English fashion does not actually follow the rule implied by similar words such as "stratify" to "stratification" or "certify" to "certification."

You guessed right. Fixed now. Thanks all!

All my words are declared integer.

So I suppose words are really inexact.

Once can use fractional words for increased precision.

Then there's the matter of rational and irrational words.
