Fogg 427 Posted July 23, 2011 Share Posted July 23, 2011 I wonder how the Auckland ferries compare? http://www.stuff.co.nz/environment/5329506/Wellington-ferries-seen-as-huge-pollution-problem Link to post Share on other sites
grant 40 Posted July 23, 2011 Share Posted July 23, 2011 that article is mostly talking about LFO, light fuel oil, which is thicker and blacker than diesel but a whole lot lighter than the HFO (Heavy fuel oil). To the technically inclined the fuel in welly is 180 centistokes (measure of viscosity) but off hand can remember any other grade to compare it with. It is the Cook Strait ferries burning the LFO currently, because that is the lowest grade (& cheapest) available in Wellington. When you start using HFO the storage tanks and pipeline need heating just to get the stuff to run. Really unpleasant to spill that, in fact generally HFO is worse to spill the crude oil, at least crude has some 'lighter' parts to it so the overall 'thickness' isn't to bad. I'm pretty sure all the Auckland ferries will just be running on diesel, probably to almost the same (if not the same) spec as automotive diesel. No reason all shipping couldn't run on diesel, it just depends on how much more the masses are prepared to pay for anything moved by sea, I'm guessing not enough to make it happen.

wheels 543 Posted July 23, 2011 Share Posted July 23, 2011 It's one of those articles where you get some of the info and used in varies ways to imply or suggest something that may not actually be. Firstly, ALL Fuel is toxic. Just in different ways. Actually Deisel exhaust fumes are considered to be perhaps the most carconagenic pollution produced. Yes Sulphur can cause Sulphuric acid, but that doesn't mean we are all going to get horrificaly burn't or scared when we go out in the Wellington rain when a Ferry is coming into port. Also not that the fella that says about the "more pollution than all the cars for a month" says " Probably. It is not actually a fact, just a statement that may or may well not be true. And what kind of pollution are we talking about. Besides, Cars produce Di-Hydrogen Monoxide in large quantities. About 1ltr for every 10ltrs of fuel burn't. Di-0hydrogen Monixide has been responsible for 67 deaths this year already. 23% higher than last year. Yet no one has tried having that banned from emmissions Link to post Share on other sites
johnMi 2 Posted July 25, 2011 Share Posted July 25, 2011 In fact, I mix a bit of salt with Di-Hydrogen Monoxide and use it as lubrication under the hulls while I'm sailing. Link to post Share on other sites
wheels 543 Posted July 25, 2011 Share Posted July 25, 2011 JohnMi, I think what you meant to say was, you mix Sodium Chloride at a rate of 35g/ltr of Di-HydrogenMonoxide Link to post Share on other sites
Brien 22 Posted July 25, 2011 Share Posted July 25, 2011 Wheels you don't have enough to occupy your mind. You need to get back to sea but keep an eye out for any H2O that might be lurking out there. Link to post Share on other sites
wheels 543 Posted July 25, 2011 Share Posted July 25, 2011 As long as it lurks on the outside of the boat, I will be happy. Link to post Share on other sites
Guest Posted July 30, 2011 Share Posted July 30, 2011 ""One oil industry expert, who did not want to be named, said he believed the ferries were responsible for 80 per cent of sulphurous gases over Wellington."" AHA!! they are serving vindalooo on the ferries! Link to post Share on other sites
