This technical report provides guidance on the use of biofuels in compliance with Class, EU, and IMO regulations. It outlines the increasing interest in biofuels as alternatives to conventional fuels due to new regulations aimed at reducing air pollutants and greenhouse gas emissions. The report details the requirements set forth by MARPOL Annex VI and ISO standard 8217, which govern the quality and specifications of marine fuels, including biofuels. It explains the safety and operational considerations for using biofuels, including flashpoint requirements and the International Safety Management Code obligations. The report also discusses the implications of biofuels on NOx emissions and the classification requirements for vessels using biofuels. Furthermore, it provides guidance for operators on statutory NOx assessments and the necessary documentation for using biofuels, including the potential for class notations based on the percentage of biofuel used. The report emphasizes the importance of compliance with established regulations and the need for proper testing and verification processes.
