In shipping the cost is transferred easily down the line; capital investment in new vessels and new technologies is pretty slim because of that. Also the time spent in dry dock might as well cost you more than what you’ll gain through the service time of the vessel since many of these vessels change hands frequently sometimes even several times a year. Also because how risk is managed in the shipping industry none of…
Hm, really stupid naive question here. What happens if violating ships were basically seized

Re: Ships fitted with ‘cheat devices’ to divert poisonous pollution into sea
#42I was wondering what it would take to replace a current container ship by a sail boat, like a clipper. Apparently, each container ship has more or less a 100 times the tonnage of a clipper. Independently of the speed of the ships, the cost of the crews would probably kill the idea, except for goods with a very high margin, but there must a fuel price (including carbon tax) where this should become economically viable…
There are lots of experiments and even production ships with sails these days. Google for "sails on container ships" for lots of nice pictures and articles. The sails don't look like historic sails - they are often rotors that look like cylinders. Maersk's Pelican, for example, is supposed to get 10% from its rotor sails. Tangent: why do wind turbines look so conventional, with their propellers? There is a lot online…

#43If you want to read the other side's argument, here it is, from International Bunker Industry Association: https://ibia.net/facts-and-fears-in-the-open-loop-scrubber-d... The main point is that there is regulation for washwater based on science. The article describes "warm, acidic, contaminated washwater containing carcinogens including polycyclic aromatic hydrocarbons (PAHs) and heavy metals", but regulation in fact…
This industry is one of the dirtiest, and least responsible to the world.

#44> the sulphur emitted by the ships is simply re-routed from the exhaust and expelled into the water around the ships, which not only greatly increases the volume of pollutants being pumped into the sea, but also increases carbon dioxide emissions. This should be a crime
I suspect that a desire to cater to people with "something drastic must be done" attitudes is how we wound up with half baked rules with seemingly obvious loopholes in the first place.
As another commenters pointed out, there are standards for discharge water and these systems presumably meet them. If you think those standards are wrong then take them up with them. The ship owners are acting in rational self interest within the letter of the law here. It's hard to find fault with that.

Probably hard to do in international waters but the bigger countries could always just say that any vessel doing this is blacklisted from docking in their ports. Every ship operator would just retrofit their vessels if that were to occur.
Exactly. I was gonna say that by some international port blacklist we can easily punish them, and of force them to make a huuuuuge donation to a clean-up fund in order to have the ban lifted.

Re: Ships fitted with ‘cheat devices’ to divert poisonous pollution into sea
#50Shipping is a pretty dirty industry, because of fuel quality they use and the general lack of oversight in the middle of the ocean. I was on the board of Corvus Energy ( http://corvusenergy.com ) while working in Norway, whose technology reduces CO2, SOx, NOx, and fuel consumption by up to 30%. One installation was the equivalent of taking 10,000 cars off of the road. Thankfully, there are developments in this space.…
> Shipping is a pretty dirty industry, because of fuel quality ... You're not wrong, but no one else is/was using bunker fuel, so might as well burn it, as what else can it be used for? Can it be processed into anything more useful? (The IMO 2020 mandate may help clean things up.) > Bear in mind that shipping is also the most energy efficient form of bulk transportation (vs land or air). I was under the impression th…
Not only are drag loses comparatively small, those two stroke diesels are crazy efficient from a thermodynamic point of view (massive, slow, and high compression ratio -> crazy efficiency).
