The first fatal accident aboard a deep-sea tourist submersible is certain to raise calls for additional safety regulations, but industry experts say that any new measures may be impossible to enforce given the international nature of the business.that imploded during its expedition to the wreckage of the Titanic was an outlier, given that the maker of the vessel opted against certifying the vessel, defying industry convention.
But even as industry leaders braced for increased scrutiny, they said it was difficult to forecast what sort of changes may come. Movie director James Cameron, who became a deep-sea explorer in the 1990s while researching and making his Oscar-winning blockbuster Titanic and is part owner of Triton Submarines, said that he would support regulation to require certification of vessels, but it would have to be passed in every country where submersibles operated.
