I can't really say why the Ocean Ranger recommendation, which was quite clear, was not adopted. I suspect it was because it was during the exploration stage. Then things changed; exploration ceased and about 15 years ago production started. When the Ocean Ranger happened there was no Canada-Newfoundland and Labrador Offshore Petroleum Board. New people came on the scene and new institutions, new companies, and I suppose the Ocean Ranger recommendation, in that regard, must either have been forgotten or not considered important enough to do.
It's unfortunate, but I can't give any explanation more than that.
