Okay so the CAA want it fenced - not a major issue , I'd expect it to be in this day and age it's a no brainer with regards to basic requirements !
As for loss of contracts due to facilities - you get what you pay for at a grass airstrip = no ILS , limited facilities , limited capabilities. If you want the whole shooting match you need to operate from a full blown airport with the facilities and in built enhancements provided at the increased operational costs that can be incurred for the priviledge or live with the daily consequences of grass strip flying and its basics.
Loss of contracts due to level of service
.... well the oil companies predicted a downturn in the requirement for heli support a couple of years back and got it totally wrong - nothing new there then !. Demand this year due to oil prices and exploration in the area has probably pushed resources to the max and possibly to the detriment of the existing operations , something all customers need to put their hands up to at some stage and take some flak , instead of just blaming the operator - you can only stretch something so far until the elastic starts to break given resources available at the time - especially if thw the workload has exceeded predictions and practicality.
