Hybrid positioning system for improving location recognition performance in offshore plant environment

In case of an accident, location information is important for initial response. Therefore, in this paper, Hybrid positioning system-based location recognition technology for the safety of offshore plant workers is proposed. Generally, The zone based positioning using Zigbee communication has advantages for hardware cost and maintenance cost. The proposed Hybrid positioning system based positioning provides enhanced positioning accuracy by combining fingerprint results with weighted centroid localization positioning results to identify worker positions in the zone. In addition, deck information of workers is provided by the LF antenna. Therefore, it is expected that the proposed HPS based positioning technology will be applied for the safety of offshore plant workers.
