Helicomparator, in one of his excellent posts, says that oil companies have an obsesion with minimizing helicopter transport costs. So helicopter operators in the UK are competing with each other to win a contract. Low bid wins? If too many of UK aircraft are off line because of a possible defect, where will the oil companies find transport offshore? The UK operators may no longer be able to meet requirements.
Is there any reason they could not approach a Norwegian operator to provide this service?
