Hi Brad! I think there is no stopping the storms from destroying WERPO's deployments in very rough seas.
However, if you look at the locations, countries and coastlines where WERPO is selling their solution, you'll notice that it resembles Israel's Jaffa Port in most cases.
WERPO's port based solution is designed for calmer seas with relatively low variance with regards to changes in waves, weather, tide levels and sea forces. I think that when governments sign up for WERPO their engineers will survey multiple locations and perform the research to decide on the optimal location based on sea/weather conditions and accessibility.
WERPO also has a sea based solution that is not attached to land. This was described in a few articles.
Even with all the research I don't think they'll beat Mother Nature in many cases. But they did state that maintenance, labor, and replacement parts weren't terribly expensive and could be handled by locally trained workers.
Also if something breaks that may mean more money for WERPO :)
