Abstract

A method for detecting a leakage in a fuel supply system (10) is disclosed. Local leakage detection in fuel supply systems can be extensive. The disclosed method may facilitate local leakage detection. The method is based on the steps of performing a first pressure measurement concerning the whole fuel supply system (10) and at least one further pressure measurement for a selected set of fluidly connected monitoring segments (20A, 20B, 20C, ..., 20n) for providing pressure behaviour information for two sets of fluidly connected monitoring segments (20A, 20B, 20C, ..., 20n) that differ in size by one monitoring segment (20A, 20B, 20C, ..., 20n), and identifying the leaking monitoring segment based on the comparison of the pressure behaviour information of the two sets of fluidly connected monitoring segments (20A, 20B, 20C, ..., 20n).

Description

technical field [0001] The present invention relates generally to a method for detecting leaks in a fuel supply system, and in particular to leak detection in a double-walled fuel supply pipe system configured to selectively supply an internal combustion engine with, for example, gas Or liquid fuel fuel, such as diesel fuel. [0002] In addition, the present invention relates to a fuel supply system. Background technique [0003] Fuel supply systems, especially for gas engines or dual fuel engines, may be specially designed for safety purposes. For example, a double-wall or multi-wall configuration can be applied to all gas supply components to be used in gas engines or dual fuel engines. The double wall fuel supply system may be used on a ship or vessel on which a gas engine or a dual fuel engine may be operated. The same applies to gas or dual fuel engines used to generate electricity. [0004] The double wall fuel supply system may be configured such that fuel may be ...
