|The LNG partial reliquefaction system (PRS) is a critical system of modern LNG carriers, which liquefies boil-off gas of LNG and, at the same time, supplies high pressurized fuel gas to gas fueled engines. Proper training and maintenance are highly important to achieve constant and reliable operation of the PRS. The purpose of this study is to develop a method for using the augmented reality (AR) technology to assist the remote operation of the PRS, including its training and maintenance. For this, we develop an AR application in which the 3D model of PRS is overlaid on the real PRS, and various information such as pressure, temperature, flow rate, and other physical properties of individual equipment are indicated on the model. For accurate and robust calibration of the AR overlay, the application uses pre-defined 3D geometric information of the PRS and time-of-flight depth cameras. Using the AR application, we verify that the calibrated model is well-adjusted with the real PRS. Moreover, users could effectively monitor the current process information without any notable delay. The application can be useful for training novice workers with improved immersion and helping precise maintenance of the PRS.
