Honest question: Why don't they employ catalytic converters? Is the amount of exhaust just too much for them to be able to practically build them, or is it simply "We haven't been told we need one, so we're not going to bother."

  Why cant the developed countries have regulations which stop the ship from coming in its waters?

    There are some regulations - some ships switch from burning heavy bunker oil to diesel when close to port.

      The regulations have increased heavily in recent years. E.g. near the U.S. and Europe. It's not just close to port anymore. See e.g. http://www.joc.com/maritime-news/shippers-brace-low-sulfur-fuel-surcharge-january_20140925.html http://www.joc.com/maritime-news/shippers-brace-low-sulfur-f... for details. Small quote from the article: Maersk Line CEO Soren Skou said in a Copenhagen presentation yesterday that lower sulphur fuel was more expensive and would increase the carrier’s bunker cost by estimated $200 million a year. That additional 200 MUSD/year is just for the stricter rules in Europe. You can save a massive amount of money by "ignoring" these rules. Meaning: unless it is checked, there is a huge risk of unfair competition between companies which abide by the rules and companies which do not. Especially if a company is in difficult times it needs to be checked carefully. You'll notice that the bigger companies are ok with such rules, as long as it applies to everyone and is checked thoroughly.
