Dear

What happened if we use normal heli at sea platform with basic coating or as semi navalized. I know corrosion issue , I also know navalized one price 6 times or more higher than normal one . Since 1960s if I don't understand wrongly no completly navalized heli exist after that this concept matured. Than to 1960s they operated non or semi navalized ones.
For example anyone can say that if u use none navalized or semi / partially one, u have to major maintenance them after 2000h under sea air condition also u have to spend 20 percent of its costs also Mtff time reduced to 3000 h or like that.
Some degree semi navalized Gokbeys may be accepted at least on OPVs . After that obtained experience with them we can go on. May be main issue at here producing heli number 3 times number of the OPV as flying skeletons. Like Operating one - Mintanence one - Spare one. But as electronics suits number equal to operating ones number.
