Small craft; permanently installed fuel systems and fixed fuel tanks

This document establishes comprehensive technical requirements and safety criteria specifically designed for the fuel systems and fixed fuel tanks installed on small vessels. It addresses the engineering principles necessary to ensure the secure containment and transport of combustible liquids within compact marine environments. The provisions cover critical aspects such as tank placement, material selection, venting arrangements, and the integrity of fuel lines to prevent leakage and potential fire hazards. Special attention is given to the mechanical connections and support structures to withstand the dynamic conditions typical of operation at sea. By defining clear specifications for installation practices, this international specification aims to minimize risks associated with fuel handling and storage on smaller craft. The guidelines facilitate consistent manufacturing and maintenance procedures across the industry, ensuring that all fixed fuel installations meet a baseline level of performance and reliability. Adherence to these guidelines supports the overall safety of crew members and passengers by reducing the likelihood of fuel-related incidents during normal voyages or emergency situations.
