Maritime Organization (IMO) issued higher cost low sulphur fuel oil (LSFO) nologies which integrate energy storage. Regulations, fuel costs & availability “IMO 2020 Rule” to cut fuel sulphur or marine gasoil (MGO)—or for a high To gain an understanding of the best The IMO 2020 Rule requires ships to use MGO fuel with no more than 0.5 percent sulphur content compared to the current limit of 3.5 percent. In ships operating in Emission Control Areas (ECAs), which in North America extend 200 nautical miles from U.S. coasts, the sulphur content limit remains at the 2015 standard of 0.1 percent.
Sulphur and sulphur compounds natu- rally occur in petroleum, and special processing or low-sulphur feedstock is required to produce fuel with low sul- phur content. Due to tight supplies and strong demand as the year 2020 draws near, there is no guarantee that LSFO supplies will be suf? cient. To be con? - dent in achieving the reduction from 3.5 percent to 0.5 percent, operators will need to do signi? cant planning to ensure fuel is available for their vessel or ? eet to avoid penalties.
Possible shortages could lead to sig- ni? cant price swings, making budget- ing and investment scenarios complex.
Industry analyst Wood Mackenzie fore- casts a 25 percent increase in price for lower sulphur content fuel based on a
SOx scrubber adoption rate of about two percent, but some scenarios could cause
LSFO prices to spike by as much as 60
