The repair process..

 

 

And oops

 

Tuesday's update shows the problems are broadening, with stopovers in the Pacific depleting supplies there.

 

So much for stopping in at Fiji

 

 

 

hence the WLG stop

I remember back when APEC was in Auckland airlines were tanking in fuel. 

 

It sure is interesting to see how the airlines/big oil are implementing contingency plans.  Infrastructure redundancy doesn't have to be the same mode (i.e. when the earthquake closed the Picton to Chch train line it was overland trucking & coastal shipping that provided redundancy, rather than an additional train line).  So it would be super interesting to see how the costs (including loss of business) shake out.

Surely you could just build a couple of access points /pumping facilities on the pipeline. One third and then two thirds of the way down from the refinery.

 

Then, in the event of a leak, you would only need to truck fuel for one third of the length of the whole pipeline in order to skip the fault.

 

That would be almost as good as having a second pipeline for a usefully lower cost.

Unless, like in this case, the pipe is broken 8km south of the refinery.

 

EDIT: Just re-read the post, I think I get the suggestion now, ignore the comment above!

Except you can't take the full volume of the pipeline into a tanker. There's no way to push the same volume when you are going from a big pipe into a little pipe then into a tanker, driving it down to another point then into a small pipe then into a big pipe. You'd end up with a tiny percentage of your pipeline volume.

 

Then there's the physical configuration of the pumps, which won't be designed for suction etc etc etc.

I like this idea.

 

The obvious? place for these would be at the pumping stations at Kumeu and Wellsford. It's not just a matter of a plug on the side of the pipe. You would need some way to isolate the pipeline above and below each access point, and have some kind of reservoir/tank farm. 

 

But here's some maths:

 

The pipeline runs 300-400 cubic metres/hr. A road tanker is about 30,000 litres = 30 cubic metres. So the pipeline is the equivalent of about 10-14 road tankers per hour 24x7 i.e. a tanker every 5 minutes. It takes about half an hour to empty/fill a tanker, so you need 5-7 tankers simultaneously unloading, so each of these access points would be the size of a significant truck depot. If there's an hour's drive (based on a guesstimate of 3 hours drive between Wiri and Marsden Point -- Google Maps says 2h8m by car) between access points, then in a perfect world 24 road tankers (6 loading, 6 unloading, 6 full on the road, 6 empty returning) would be in use 24x7. Probably you'd need twice as many in the real world? And 3 drivers per tanker (short-term, 4 long-term).

 

By comparison, trucking fuel all the way from Marsden Point to Wiri would require about twice as many tankers (ideally 6 loading, 6 unloading, 18 full on the road, 18 empty returning). There would be some benefit in having the tankers going direct to the fuel's destination instead of unloading at Wiri to load onto another tanker, so the benefit of the access points would be somewhat less.

As of this morning it was still possible to book return flights AKL tomorrow morning to WLG and SYD returning Fri afternoon.

 

Apparently it's a CRISIS!

 

As far as I'm aware nobody died yet. I also despise the news media in NZ.
