These wave sound like Black Swan events - real events whose probabilities don't fit our current understanding and models. On one hand of course it's unsafe to send ships out on the ocean, but on the other hand, there are tens (hundreds?) of thousands of ships at sea every day and these waves weren't even measured until 1995. Right now they need to figure out X and then shipbuilding and insuring will adjust accordingly.
