Some observers have compared IMO2020- the restrictions on sulfur in marine fuels which took effect on Jan 1, 2020 -with the Y2K drama of two decades back.
During the Y2K runup, there was much consternation and fears that all computers would stop running, shutting down commerce and everything else. Fast forward to the end of 2019, with great concerns that vessels could not source compliant fuel, or worse- that various blends would gum up cylinders in vessel engines.
The year 2020 saw a whole host of problems for the maritime business sectors, but fuel problems were not at the top of the league tables; fuel matters paled in comparison to more serious issues that arose. Like the computer non-crisis 20 years prior, maritime businesses had time to anticipate and prepare.
