Average height of offshore platform helideck

Our contracted 225s under IFR and our specified performance requirements would drop 50kg per degree above 25 degrees C. So at 35C, we would lose 500+ kg with an MTOM of 10400-10450 with the flight manual penalty for the forward fuel pods fitted.

I thought that sounded a bit low so I checked some platform drawings (UK NNS). We have 5 at approx. 166', one at 157' and two at 235', all fixed platforms. I would expect the Norwegian ones may be a bit higher still. However CAP437 does state that if a landing area is much in excess of 60m (197') above sea level, the regularity of helicopter operations may be adversely affected in low cloud base conditions.

FED,

The Vertrep Contract choice of aircraft had to do with Hangar size and lift ability and the fact the Puma 330 is a very good helicopter for that Mission and most importantly.....cheap.

Quite a lot, actually. Just to cheer you up an American contractor uses 330s to vertrep the US Navy.

USNS ships? (Memory foggy, but I seem to remember that Kmax was in the mix for that some years ago, but lack of IFR cert was an issue).

I'm surprised by the claim that 27,000 people have signed a petition calling for the type's permanent grounding. I wonder where this petition is being hosted?

possibly bell and sikorksy??

@riff_raff

Not much different than Croatia buying refurbished OH-58D's from the US Army.
Buying?!
All official sources have info about donation of new airframes with refurbished aggregates and avionics (approx 300 BH on
average unit). Yes, some support and spares are contracted and paid.

This petition has nothing to do with the Bergen crash. It was generated after the ditchings with the oil pump problems.

This article from July still sums up the situation for me

Future Of The Super Puma In Doubt? | Things With Wings

AH must have one of the trickiest redesigns in aviation history. how often you have to fundamentally rethink a primary module in the twilight of a model's life?

Writing the accident report will be tough enough - responding and addressing the recommendations will be a major engineering challenge and then the toughest of all dealing with all the emotional fall out. It is beginning to look like it was a stretch too far.

You could ask the folks at Kaman. Look at what they did from SH-2F to SH-2G? That was a comparatively late upgrade to that airframe.

It is imperative that Eurocopter get the EC225 back in service.

It is intolerable to customers to have Sikorsky have a monopoly and a simultaneous shortage of airframes as that will just drive cost up for the oil companies at a time of low oil price.:yuk:

Ignore the petitions! With oil workers putting up with 30% pay cuts and more time offshore they will take whatever helicopter their company aviation advisor deems safe enough, just as they have done before after past accidents.:ok:

Obviously the advisors have to play being let-down with Eurocopter for the moment, to divert attention from their own past aircraft selections, but the world goes on.

Frying Pan 19th August 2016 08:40

Back with a bang I see SM. Others will be pleased.

Bit of an idiotic post though. Put safety second to save the oil companies? Doesn't wash with me. The world does indeed go on, so let's make it better. In the olden days people used to fly the Comet! I think your retirementland is up there in cloud cookoo land.

Exxon survived Valdez, BP survived the GOM, and Piper Alpha didn't stop North Sea production. Oil companies will always do just fine, just like your pension I imagine.

FP - I smell SM's sarcasm. I hope.

Frying Pan 19th August 2016 09:17

Oh crap, did I just bite? :oh:

Agreed but the Seasprite is a different beast and received a ton of government support right up until its initial cancellation.

The oil industry has already given up on the Puma and Kuwait will be asking some serious questions behind the scenes.

Whatever AH do I feel a rebranding coming

True enough.

I thought AH was already a rebranding of EC. :cool:

HeliHub The distressed H225 fleet ? A review

How long realistically do we think the fix will take for the 225? ie until the ac can be flown again commercially within EASA?

Ignore the obvs qn of 'who would fly it?' on the customer side, just purely the mechanics of the solution and subsequent approvals from EASA.

Long time for the leasing companies to sweat it out with their own internal issues and idle aircraft.

birmingham 19th August 2016 15:13

It will clearly be a considerable number of months to make an effective and robust redesign and implement that. To rush it would be totally counter productive.
