The aim of this research is to develop an algorithm and application that can perform real-time monitoring of the safety operation of offshore platforms and subsea gas pipelines as well as determine the need for ship inspection using data obtained from automatic identification system(AIS). The research also focuses on the integration of shipping database,AIS data, and others to develop a prototype for designing a real-time monitoring system of offshore platforms and pipelines. A simple concept is used in the development of this prototype, which is achieved by using an overlaying map that outlines the coordinates of the offshore platform and subsea gas pipeline with the ship's coordinates(longitude/latitude) as detected by AIS. Using such information, we can then build an early warning system(EWS) relayed through short message service(SMS), email, or other means when the ship enters the restricted and exclusion zone of platforms and pipelines. The ship inspection system is developed by combining several attributes. Then, decision analysis software is employed to prioritize the vessel's four attributes, including ship age, ship type, classification, and flag state.Results show that the EWS can increase the safety level of offshore platforms and pipelines, as well as the efficient use of patrol boats in monitoring the safety of the facilities. Meanwhile, ship inspection enables the port to prioritize the ship to be inspected in accordance with the priority ranking inspection score. 相似文献

船舶动力机械系统一旦出现故障直接威胁船舶安全,但是船舶服役后难以增加设备完善动力机械运行状态的监测。为此,提出了可监测性设计理论内涵,在常规船舶设计建造阶段考虑动力机械系统的可监测性,从而构建出可监测性设计理论在船舶动力机械系统设计中的工程应用框架。以远洋救助船动力机械系统为例,分析了可监测性设计理论在机械系统设计中的具体应用。实践证明,可监测性设计理论在船舶动力机械系统中的工程化实施增强了其可监测性,大大提高了自身状态监测和故障诊断能力水平,并且为船舶动力机械创新设计和机械系统的可再制造提供了保障和技术支撑。 相似文献
