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.

I. Introduction

Recently, the interest in the offshore plant industry to collect marine resources has been increasing due to the increase of resource consumption. Therefore, the importance of offshore plant safety and accident prevention measures is also growing. Since accidents occurring in offshore plants are difficult to obtain outside assistance, effective early response is important to minimize accident damage[1]. A positioning system is required to obtain the position information of the workers in order to promptly determine the initial response and instruct the workers in case of an accident.
