Could it be that the mission packages were never able to be implemented, and the massive overages on maintenance time vs. what was advertized. there were a huge amount (for Norway) pilots and engineers re-treaded from fixed wing to rotor, including some going to Allied Wings in Canada, and moving to new bases etc, for an aircraft that never really materialized. a LOT of wasted money for an airframe that never really reached operational capability, even in its Coast guard role...
