Many of the vessels used during my company's hook up phase are bow decks. All of our decks are unstable as our facilities are semi submersible in very deep water.
The bow decks on your ships are likely to be less than Cat 1 so already suffer from reduced limits. The Semi Subs are likely to have different (greater iirc) limits.
I am glad our operations are not in the NS otherwise the pilots would shut us down. We try not to fly at night but sometimes its unavoidable.
See if you think that when someone puts the tail rotor through the bridge when they lose references. Why do you try not to fly at night? I hope it is because of the science based reasons you quote in your next paragraph.
HC tells us the 225 has auto hover capability? What technology do you need to make a night bow deck landing safe, because just to ban them at night completely is not acceptable for the industry that contracts your services. How about some scientific analysis which has some credibility.
It's not the hover that is the problem it is the bit from the hover to the deck. You sit there watching the deck heave around below you and getting the PM to tell you if there are any big waves coming. Good game, I recommend it.
As to your comment about 'completely unacceptable, blah, blah' well you are wrong. It is acceptable in Norway as they don't do them. What you _mean_ is that you don't want the cost/disruption implications (sorry, third push at the wheelbarrow).
As to how to make it safer, HC beat me to it. Short of not doing it, crew composition and power margin and maybe tighter heave limits. I'm not a fan of any bow deck being Cat 1.
Finally as to the scientific analysis bit the safety reviews ongoing have a simple choice: do they want to have a look at the tip of the iceberg, i.e. the crashes that have occurred and address those specific problems or do they want to have a look at the whole iceberg. The bit below the waterline is stuff that hasn't happened yet but might. Some of the things that may be part of the submerged iceberg might be issues that are raised here: bow decks, etc. You can take these pilot concerns on board or not, it is entirely up to you. If, however, you want scientific analysis to support these concerns you will probably have to wait for a future AAIB report with bodies attached.
