Why NZR have to pay for it, not taxpayer?

Because they make zillions of profit ...and should have 'invested' earlier to mitigate events like the current crisis. Shareholders can afford it.

Anyway they'll pass the cost on which means the end consumers end up paying anyway.

,..maybe nationalise the whole industry instead

perhaps a bit too much fancy going on in this thread

A 2nd pipe isnt economic, perhaps the best solution is to expand the Wiri storage , because there is no problem with supply in the medium term, ships can do it if necessary , its more about the time it takes to reconfigure the delivery schedule and the initial delay in achieving that.

I must say I'm amazed they can have different liquids in the pipeline and then monitor the 'interface'.

The different fuels used to separated by an interface of water and there is a manifold at each end, when the fuel load changes, the manifold is channeled so the interface liquid is put into a separate tank and then the successive fuel then directed to the appropriate storage tank - A1, Diesel, 91 octane... those are refined at Marsden Point but I lost track a while ago if 95/98 PULP is refined at Marsden Point as for some time it wasn't and mainly imported from refineries either in Australia or SE Asia

reports in 2012

Under nationals drifting fiddling 9 year watch.

[COLOR=rgb(21.093800%, 37.109400%, 57.031300%)]Minor refinery outage[/COLOR]19
Outage scenario and expected response under status quo

1. A minor refinery outage is an incident that disrupts the refinery for three weeks. Supply fromthe refinery will be re-established before supply could be fully re-established via imports.
   
2. The following assumptions are made about the response to the incident:
   

[IMG]file:///page25image6504[/IMG] ••
•••

refinery tankage and the RAP will be available within three days
a number of oil companies will divert cargoes destined for other countries to NewZealand (two within the three week outage), and government will relax fuelspecifications if appropriate
oil companies will draw down on normal buffer stock and safety stock in terminalsairline flight schedules will be rationalised
airlines will bunker fuel into New Zealand.


[COLOR=rgb(21.093800%, 37.109400%, 57.031300%)]Q14. Are there other factors that can be addressed to enable industry to betterrespond to a major refinery outage?[/COLOR]


83. It is
period, and thus that there may be brief stock outs in certain areas for short periods.


estimated that two percent of normal petrol and diesel demand cannot be met over this


84. While 24 percent of normal jet demand cannot be met over this period, it is assumed thatairlines would manage this shortfall by rationalising flights and bunkering

That 2012 report was an updated version of a 2005 report ...with much the same conclusions

What happened after 2005 mate?

Couldn't have greedy ol companies and shareholders spending too much on infrastructure could we.

The pipeline was constructed in the 80s and it's been operating out of sight, out of mind for 30 odd years. There are many examples of single point failures in infrastructure - South Australia had only one HT electricity interconnect with Victoria which failed completely with the loss of several transmission towers in a storm, this would have been less of an issue but SA had shut down most of the coal powered thermal stations and relied significantly on wind farms that had to be shut down in the storm.

The Centennial Highway coming out of Wellington is another example where the capital could be cut off... the Cook Strait Power Cable, Southern Cross Cable, Auckland Harbour Bridge are infrastructure with high reliance and limited alternatives. We rely on critical infrastructure everyday - we can build resilience but try to explain to a consumer, ratepayer or taxpayer that they have to pay for it for surety of supply...

They have upgraded the Cook Strait cables over the years ..not just one cable ....

1. Five new power and telecommunication cables were laidin 1991, and a further two telecommunication cableswere laid in 2002. They lie unburied on the seabedacross Cook Strait.

Everyone seems to only be worrying about another pipeline failure. I would think a failure in the refinery itself would be many times more likely.

...South Australia had only one HT electricity interconnect with Victoria which failed completely with the loss of several transmission towers in a storm...

You are definitely treading on my turf here and I can say quite categorically that you are completely wrong with that statement.

this would have been less of an issue but SA had shut down most of the coal powered thermal stations and relied significantly on wind farms that had to be shut down in the storm...

The wind farms, disconnected themselves from the grid, as a self protection measure, because of the high number of voltage dips in a short space of time.

The interconnect was then forced to self protect and disconnect as well.
