It would appear that the grounds for termination are the inability of NHI to meet the contracted availability. I’m sure the Norwegians will have had discussions with the Australians and, based on their experience, seen little light at the end of the tunnel. NHI state they have modifications/enhancements in the pipeline (but at who’s cost?) and Norway’s decision is groundless.
Grabbing the popcorn to watch the outcome of this one.
