Norunway.

If Irish IFR fuel regs are same as UK you have forgotten to add 10% of calculated fuel usage and 1/2 hr loiter time at Vy which would equal about 130kgs in the Cork - rig - Cork - Shannon route. I also believe that the weight penalty for Class 1 onto the rig is 200kgs so as 100kgs of fuel is used to reach and IFR approach rig then another 100kgs needs to be taken off disposable load ex Cork. A total of 230kgs off your figs.

Using your basic figures this gives a disposable load ex Cork of approx 275Kgs or 2 workers and their bags or at a push 3 workers and no bags.

Good spot not a very good payload is it.

As per FODCOM 27/05 standard weights for offshore are male = 98 female = 77 but in the case of the 135 it will be more like actual weights due to the narrower margin.
For what it is worth.

Having got your fuel burn wrong and your basic IFR fuel calculations wrong are you really in a position to comment?

Cheers

Hi TeeS

Are my calculations nearer the mark - only thing I wasn't sure of was the penalty for operating Class 1 to the rig (which I believe is part of the contract terms).

Now I am retired it keeps my mind active doing these theoretical sums

Sorry JIGSPY

I have no idea of what the contract terms are, I just got the impression that there was a random number generator producing a lot of the figures quoted by Norunway.

Regards

The posted calculation of 505 kgs payload didn't take into account the 110 reserve fuel or the 10%. Someone already posted this but was rudely discounted. Also 20kgs of deck time only allows for one landing when they regularly have more than that. With 8 pax possible shuttling they will need two shuttles which is more like 100kgs deck fuel.

In any case, Bond do a good job of making the numbers look better. The gas company is in for a bit of a shock.

Also heard the aircraft hasn't been approved yet for the operation, but again is only rumor.

JIGSPY - We do not operate Class 1 to offshore elevated helipad locations (PC1), due to hugely restrictive payloads, inappropriately high TDP's (cannot guarantee rejected take off outcome) amongst other issues. It will be PC2 with exposure or PC2 if the sea state can be considered suitable for a 'Safe forced landing'.

Lenticular you are spot on with your statement, the guys say it will be a minimum of two shuttles but client is very happy as they get a brand new aircraft at half the cost of the previous heli. The aircraft has been out to the rig with the CAA and completed all the necessary paperwork so it looks on target for the Jan 1st start date

Half the cost of the previous heli but twice the number of flights.

Maybe it was
twice the cost with half the number of seats full

If the weather is suitable I'm sure the flights could VFR, so an onshore diversion will be sufficient, with VFR reserves. Even with an S76 payloads are reduced in the poor weather seasons due to all the IFR reserves. Over the course of a year things average themselves out.

The ROI is very expensive to live in at the moment, hope they are paying enough!

I always thought Shannon was 'onshore'???

Wonder how many days a year there are which would require IFR out of Cork.

Either way, it will be interesting come january 1st, to see how well the contract runs as the customer expects.

Who knows. Who cares? It'll either be acceptable or a bag of sh*te, and the contract will go to someone else in the big game of swings and roundabouts which is the wonderful helicopter industry in the UK and immediately surrounding islands.

"Half the cost of the previous heli but twice the number of flights."

In the eyes of the customer that makes it "cost neutral" , might mean more flights but it doesn't cost anymore overall - a result as far as they will be concerned - they will only be interested in the bottom line

They used to use the SA365 FYI.

If the 135 does not work out it will be a doddle for Bond to change it for a AS 365.
I would have thought the important thing for Bond is that they have got the contract keeping it for them shouldn't be too difficult.

Remembering how they work.

But a 365N3 at 135 rates - not a sound financial proposition. The customer is unlikely to pay 365N3 rates when the contract specifies a 135. Afterall you don't expect to pay the increased cost of a hire car if the renter has to upgrade you. Also 365N3 qualified pilots are more likely to leave when the oil exploration climate improves as the Bond Irish pay is low compared to the N Sea.
