Design of the security alarm control system for LNG-fueled vessels

With the rapid growth of the economy, air pollution becomes increasingly serious and environment protection has attracted more attention. It is a fact that ships produce enormous air pollution emissions with high energy consumption and research has been constantly carried out on clean energy applications. LNG as an alternative clean marine fuel to run on ships is still at an initial stage. Different from traditional energy resources, LNG may generate risks in the process of application. Security alarm control system will effectively monitor risk sources preventing the occurrence of danger. Based on the deep analysis of the pros and cons of the existing structure and mode of security alarm control system of LNG-fueled vessels combined with the work and risk characteristics of marine engine, storage tanks and gas supply piping which have different danger sources, design a new type security alarm control system to optimize the structure design and logic control mode and implement functions of automatic detection, alarm and device control of combustible gas from risk sources. The system is stable and reliable with easy operation effectively reducing the risks of LNG-fueled ships.
