Somehow I doubt that the relative wind was either a governing factor or of primary concern to the two pilots in this instance. Our helicopter land on operations had a limiting factor of 5 degrees of roll and naturally the aircraft was always landed into wind but the relative wind direction was less…

5 degrees of roll !! wouldn’t have been worth feeding the flight crew if we had that rule in the Bering sea.

The wave direction are the governing factor for minimizing vessel motion. For helio operations both wind direction and vortexes caused by the superstructure and legs are an issue. At least that is the case on jack-ups and anchored semi-subs/drillships, where the heading can’t be change while on l…

Like I said- been a minute- but I know what I saw at least hundreds of times was landing aircraft with way more than 5 degrees of roll.

[image] texastanker: way more than 5 degrees of roll. The question you need to ask is …….was your Pilot transfer helicopter fitted with tyres or airbag armed steel skates? Steel on steel has a very low friction coefficient and synchronous rolling even at 5 degrees can create many difficulties…

HH-52 with rubber tires - and between the pilot and the LSFO the objective was touchdown on as level a deck as we could- and get the tie down crew on it fast

Memory jog - think we did the calc for 30 deg relative wind.

“Two point off the bow” is for the waves, not wind direction. And for least vessel motion. Heilo operation was not much of a consideration on cargo ship, or when the rule of thumb was “invented”.
