1-2 hrs a day in the water = 7-14 hrs a week = 28-56 a month
assuming you did month on month off after the first 2-3 months of initial training and induction and getting onto a regular slot, 4 trips for the rest of the year = 112-224 hours in the year.
Assuming you were not going to do all of the flying and/or there was another trainee there, assume you get 30-60% of the flying = between 33.6 hours and 134.4 hours.
Of course as these are Drill Support flying hours they would count for a tiny percentage if you were then sent on a job working off a boat, mid water, using acoustic tracking in zero vis playing with crane wires.
So the answsers still between zero and 200 😀
