A Risk Assessment Model for Navigation Safety of Maritime Aquaculture Platform Based on AIS Ship Trajectory

Abstract

With the rapid increase of maritime aquaculture platform, how to reduce its impact on maritime traffic safety is of great significance to the rapid development of shipping. According to the characteristics of aquaculture platform and maritime environment, The aquaculture platform is superimposed on the ship AIS (Automatic identification systems) big data traffic flow analysis platform. The effects of the distance between the marine aquaculture platform and shipping routes, port facilities and cargo vessel traffic flow channels were studied. The effects between the platform and meteorological conditions, fishing vessel activity and passenger routes were studied. The mathematical assessment model of navigation safety risk of aquaculture platform based on MTLAB was studied. Taking the “Qiandong No. 1” semi-submersible wave energy farming platform as an example. The navigation safety risk assessment is carried out and the risk control measures are put forward. Experiments are carried out with actual data and the effectiveness of the proposed method is proved.
