Good for the EC-135
But the EC135 carries half of the passengers of the S76 and spends twice the time in the shop than a S76C++. So the machine to depend on to get 700 workers safely off the platforms is not a 5 passenger EC135 but a 12 pasenger S76. Deck time is expensive and only one helicopter can occupy the deck at any time You move more people in a shorter time span per landing with the S76 than a EC135. And at over $100 per barrel time is money.
