The process you describe - is it all done remotely?
The process is normally managed remotely. However, I am not totally familiar with the actual process in place. I would assume that good liaison is required between the heli crew and the department managing the remote controlling of the nacelle and blades to ensure that everything is in the optimum position and locked in place.
My earlier comment regarding the winching area came about as the Danish authorities wouldn't classify the winching deck as an "aviation facility" so it then came under the normal HSE rules and was classified as a working platform at height. This meant they had to erect a permanent fence around it, thus presenting a twofold risk to winching operations. The possibility of catching the cable around the fence and, worse still, the possibility of dragging the winchman on the wire through the fence if the heli has to dive off to one side for any reason. Thankfully for the ongoing heli operation there this has not happened - yet!
It certainly needs to be taken into account in the risk management.
