I for one won't be supporting this stupid petition (plus it's badly worded and misspelt).
To transfer to a single type (s92) is both impractical & unrealistic, There isn't enough of them worldwide to meet demand & what do you do until there are, tell the folks offshore to stay put? So, the only practical option available under the terms of the petition is to scrap helicopter travel.
No helicopters simply means everyone offshore has to go offshore by supply boat & transfer to the installation by man-riding basket, an inherently risky process in good weather. How many lives would be lost each winter if we had to go back to only boats & baskets?
My current job means that I don't have to travel offshore as often as I used to, but I am more than happy to get on a EC225 or 332 to do it.
