Hazard Identification of Methanol Fuel System on Ship

Abstract

Today, dual fuel diesel engine (DF-DE) on board ship is proven to produce smaller gas emission. The most common configuration for DF-DE is by using natural gases as main fuel but does not rule out the potential of other alternative fuel such as methanol. Methanol has potential application on board as low carbon, sulphur, NOX and particulate matter. Furthermore, it can produce with natural gas and biomass that has smaller emission from a life-cycle perspective. However, Methanol which classified as low flash point fuels (LFL), it has adverse effects including toxic, volatile and corrosive. This paper will specifically identify the potential hazard of methanol fuel system on board. Even though the further proposed design of Methanol fuel system is still not fully intact, the preliminary design is already developed and can be determined as a basis for hazard potency identification. The method for this identification is Hazard and Operability (HAZOP) which refers to BS IEC 61882:2001. With an expectation that the outcome from this identification can become the recommendation for further more detailed proposed a design for methanol fuel system.
