I m sure risk assessments were done for this sort of work, happens all over the world. If there was a more economical way then that would have ben used.
Like any longline utility work if the noise stops then there are very few options, like any job there is a risk but engines don't stop that often
The 350 has a lifting window through the floor. View is limited but useable unless you are big. It is much easier out of a 500 where you can lean out of the window, but she won't lift what a 350 will !
