Abstract
In recent years, with the rapid development of world economy, energy consumption increases sharply, and the environment is deteriorating. So, Liquefied Natural Gas (LNG), a renewable clean energy (Tugnoli et al., 2010) which can be used as ship fuel, is drawing attentions from more and more countries in the world. However, the transformation of the marine LNG-diesel Dual-Fuel Engine (DFE) in China as a new researching is just in its infancy, and the technology of operability, economic and security of which is not mature yet. In view of this, taking the China inland’s first transformed marine LNG-diesel dual-fuel engine GC6135ACz as an example, a risk assessment about the failure of this engine has been carried out based on an analytic hierarchy process, by which key risk factors for failure of dual-fuel engine have been obtained ultimately with expert survey data and certain risk control measures have been therefore put forward, so as to enhance the safety of marine LNG-diesel dual fuel engines.
