Possibly what might happen.
The oil company will be demanding a full investigation because their safety guy, the Unions and many pax will be jumping on the "wtf happened here?" bandwagon.
The helicopter company will be all over the crew like stink on poo telling them they have let everyone down. The crew will be told how this incident has caused a huge amount of embarrassment to the company and anger from the offshore workers particularly those who were on board the helicopter. The crew will be told how this incident has put the contract at risk and the possibility of damaging future contract prospects. The crew will be told just how much hard work and effort it has taken managers who have had to deal with the oil company in order to placate them.
The helicopter company will blame the crew entirely and if they are not demoted then written warnings will be the order of the day.
Telephone book down the back of the trousers will not be enough here.
Thats what a bloke down my local thinks may, possibly or likely happen.
