New-Level VR Marine Training System

Marine simulator is a valuable and effective medium for maritime education and training and is becoming widespread to foster the qualified and competent personnel for working in the maritime industry.However,many problems with most marine simulation systems today limit their pervasive use:the limited accessibility,immobility,the high expenditure,the long develop- meat cycle,and the difficult maintenance etc.A web-based maritime training environment is proposed in this paper as a new ma- rine training level,which fully combining web technology,VR,high fidelity simulation,and e-learning tools to create a more cost- effective and flexible training environment still with very realistic and high-interactive simulation characteristics,the system will provide a consistent and more flexible training medium for improving maritime education and training.

Studies on emergency evacuation management for maritime transportation

Marine transportation is a vital component of the world’s economy and transportation network. The number of people using passenger ships around the globe is increasing worldwide. Similar to other transportation systems, passenger safety is critical in maritime shipment. As emergency evacuation processes for ships are highly different from and more complicated than those for buildings and other vehicles, many researchers have published a vast range of documents related to this peculiar research area. However, there is a tangible lack of sufficient literature review studies that investigate marine emergency evacuation (MEE). That being the case, the potential of marine transportation and the effect of emergency evacuation operation on life safety have inspired the proposal of this study. This paper offers a review of the available literature on MEE modelling, analysis and planning during the period from 1973 to 2017 using a systematic approach. After reviewing relevant academic journals, peer-reviewed conference papers, and technical reports of agencies, relevant literature is analysed. In addition, the literature review is extended by means of proposing a framework methodology which considers different possible conditions and situations during MEE. Finally, insights for ship managers and policymakers are discussed and potential future research directions are identified.
