So in fact the crew error was compounded by the incessant waffling on the radio, miscommunication, mistakes and changes of mind by the oil company's personnel. But of course although that is mentioned, it doesn't form part of the reason why the "accident" happened according to the report, but in reality it was of course a large part of the reason.
The problem with your attitude HC is that you regard an offshore flight as a flying exercise. But actually, the flight is required to do a job. The requirements of that job change from time to time. Imagine if fixed wing pilots landed at the wrong airport. Its the same thing. If a Pilot can't land on the correct deck and reasonably adapt to the needs of the job, then they should question their career choice or consider retirement. Oh, sorry, you did retire already.
