S61N question
 

Hi everybody,

does anyone know if the S61N has ever been tested and/or certified and/or went through a SHOL (Ship and Helicopter Operating Limits) to land onboard ships (that means sailing ships) like the military choppers do?
I wonder if anyone knows which are the pitch and roll limits, if there are any, if a standard wind envelope exists...this sort of stuff.

Thanks to you all

From the Ops Manual:

Semi-subs, large barges and FSU's ............. 3 deg / 5 m

Large Ships ............................................ 2.5 deg / 4 m

Bow Decks ............................................. 2.0 deg / 3 m

Stern & Amidship .................................... 2.5 deg / 3 m

Oil Tanker, moored buoys.......................... 2.0 deg

Thanky you very much Epiphany,

may I ask you "From the Ops Manual" of which company?

It is from the Bristow Ops Man part A. Might be out of date now though.

Probably Bristow (sorry - I replied to an old page so didn't see the response!) I'd guess from his location, but those figures are standard North Sea figures as you will see from this link:http://www.helidecks.org/download%20...0p%20r%20h.pdf

To the best of my knowledge, the various values are empirically based and not as a result of formal 'SHOLs type' trials. The future trend in the North Sea is to move away from P/R/H figures and towards a more useful measurement of total motion severity.

Thanks to you all!!!
