Beaudreaux done it this way since the very first days using Bell 47's....and Boudreaux don't like change especially if it costs him money. As long as the customers want to do it cheap, and the operators will do it cheap, then cheap is the way it shall be done.
Why just think how much the price of gasoline would go up if all the helicopters in the GOM were twin engined and able to fly around on just one engine?
On the other hand....it is awfully green to fly singles....far smaller carbon footprint and that should make any Greener happy! After all....humans are of a lesser importance than the enviornment.
The way to change this single engine mentality in the GOM is to have the EPA raise the Penalties for polluting the water with all that Jet Fuel and Oils the helicopters put into the water when they ditch, roll over, and sink.
