continuation of wind limit discussion  

wind is automatic flying speed that increases takeoff and landing power availability is a good thing.  Mech turbulence and other phenomena can take that away or even seriously impact power margins.  

Rig stuff can be dicey especially landing with natural gas burnoff or turbine exhaust near or over the helipad, along with mech turb.  

Generally speaking working offshore with higher winds than reasonable for onshore ops is quite doable given fuel reserves.

Go for it, have a tear!
