Sažetak

Efforts to reduce emission of toxic gases into the atmosphere by sea transportation have been consistently carried out by the International Maritime Organisation (IMO) since 2009. IMO has introduced a regime known as energy efficiency design index (EEDI) to monitor and quantify the emission of CO2 because of its global climate impact. A comparison was conducted between trimaran hull forms without and with Axe-Bow on the main-hull with S/L=0.3 and 0.4, as well as a comparison with a monohull of comparable displacement. The CFD method was used to analyse resistance. Overall, the trimaran without the Axe-Bow can decrease resistance by 22.6%, while the trimaran with the axe-bow can reduce resistance by 25.0%. Additionally, this resulted in a 54.8% decrease in EEDI on trimarans without axe-bow and a 55.4% reduction on trimaran equipped with axe-bow when compared to MV Sabuk Nusantara 104. In addition, despite little difference between trimaran with and without axe-bow, the introduction of axe-bow has shown apparent benefits to lower EEDI.
