Rear Admiral Edward Ahlgren said: “Why this happened is still to be established. We train our people to the highest standards and rigorously enforce machinery safety standards, but unfortunately incidents of this nature can still happen.
“I assure you that a full and thorough investigation is already under way and any changes in procedure that could prevent further incidents will be rapidly implemented.
