Calculation of Temperature Gradient in Manual Fuel Change-Over Operation

Abstract:

International Maritime Organization (IMO) has revised MARPOL Annex VI to accelerate the reduction of exhaust emission. MARPOL already reduce the maximum sulfur content to 0.1% inside emission control area (ECA) since January 2015. To fulfill that requirement, the ship operator should switch the fuel to marine gas oil (MGO) before entering ECA. The change-over operation could induce several potential problems because of many differences between two fuel’s properties. The potential problems can be avoided by considering both fuel specification, fuel and sulfur concentration, as well as temperature gradient of mixed fuel using Ubbelohde diagram.
