Most of the big shippers' fleets are less than 20 years old, but even the newer builds don't necessarily have the most advanced technology.

It takes roughly a year and a half to come out with a new build of a ship, and it will still be based on technology from a few years ago. So, most of the engines still run on fossil fuel oil.
