> Research at Imperial College, London, shows that far from being rare events, rogue waves can emerge frequently, and may be responsible for some of the 200 supertankers and container ships longer than 200m that have sunk in poor weather conditions in the past two decades.

The loss of ten ships a year seems incredible to me. Surely "weather" could be avoided.

This amount of loss is steep. Why isn't this being investigated? We should have ocean swell data from every ship that capsizes.

https://www.statista.com/statistics/1326758/number-of-oil-ta...: There were 8,883 oil tankers worldwide in 2021.

If those are all ocean-going, ten a year is about 1.1%. Depending on how expensive it would be to prevent this, that may not be bad for ship owners, but it is very bad for those seeking a career in working on those ships.

1.1% of what?

Of ocean-going oil tankers.

It's ~0.11% of those

Relative to what other transportation profession, though? Pilots, truck drivers, train operators? All of them have deadly accidents.

plus 5,589 containerships

https://www.statista.com/statistics/198227/forecast-for-glob...

although the parent comment mentioned "longer than 200m" but its difficult to find containership stats by length rather than by TEU.

ignoring that though it would be 0.07% lost per year or 1 out of every 1447.

probably not too surprising, since if you pick 1447 oil tankers/containerships and audit them consider what the worst looking one is going to look like after decades of salt damage and abuse and poor maintenance.

'Surely "weather", if it were to blame, could be avoided.'

AFAIK rogue waves are called 'rogue' due to their unpredictability.

Nomenclature aside, they're somewhat predictable in the sense that if the most dangerous rogue waves will typically happen in or near low preasure systems, and especially around strong currents, where you have wind-over-tide type nastiness.

So in the sense of trying not to die, avoid the Gulf and Agulhas currents, especially when a low blows through.

This coming from an amateur sailor. I believe freight shipping etc just plows through most weather systems in order to avoid delays.

There are also source of loss, nothing can be done against. One can not even predict them.

Ocean floor methanhydrate and a volcanic shift, results in tremendous bubble columns, which just open up a shaft that can carry nothing. Water begins to boil, ship falls in, breaks apart... End of story.

Surely the gas-producing seafloor distribution can also be studied and modeled.

How many incidents of this have there been? I've heard of the theory, but no actual losses attributed to it.
