VIEW OF LATEST ECA REQUIREMENT, CHALLENGE FOR C/E FOR PURIFICATION, STORAGE AND TREATMENT OF FUEL OIL
Latest emission control requirement caps sulphur content below 0.1% in fuel oil in ECA areas. In ECA areas, distillate fuel oil below 0.1% sulphur is used, however new fuel types usually referred to as ultra low sulphur fuel oil (ULSFO), which are usually not traditional distillates, but blended products are also now being used. Diesel engine manufacturers claim that these fuels are well suited for 2-S as well as for 4-S engines. General characteristics of ULSFO fuels are:- They might have higher viscosity than distillate grades They might contain catfines They might have higher pour points There could be compatibility issues when blending with other fuels. All above factors pose serious challenge for ship staff in general and chief engineer in particular regarding its storage, purification and treatment. A) With traditional fuel oil purification system existing on ships Traditional fuel oil separators are typically equipped...
