Also old diesel engines are bad for air quality and efficiency

• defrost 4y ago
  There's an argument to be made here for refurbing the best of the container ship engines after the ship hulls reach end of life. The higher end engines are three storey high multistaged diesel engines with filters, scrubbers and some of the highest bunker oil -> power efficiencies on the planet. They're ideal for generating baseload power and worth the rejuvenation effort.

    Most (80% was the number I saw) large bunker-oil engines with scrubbers installed simply dump the removed sulphides into the sea as wastewater instead of venting it into the atmosphere. Not to mention the colossal amounts of carbon-related pollutants. Solvable problems via a retrofit to be sure, but overall I'd rather than the HFO's are simply not burned at all.
