[0006]
At present, there is no uniform standard for the setting scale of the LNG ship movement safety zone at home and abroad. The setting method is mainly based on the requirements of relevant regulations or based on the subjective judgment of the management personnel. Adaptability, there are great limitations in practical application

Embodiment Construction
[0020] In order to facilitate those of ordinary skill in the art to understand and implement the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the implementation examples described here are only used to illustrate and explain the present invention, and are not intended to limit this invention.
[0021] The present invention respectively conducts research and method analysis on the vertical and horizontal aspects of the LNG ship navigation safety field. In the longitudinal aspect, based on the ship braking distance model and the car-following theory, a calculation model for the length of the longitudinal safety field is constructed. In the horizontal aspect, from the perspective of risk analysis, a quantitative calculation model of LNG ship navigation risk is constructed by integrating the probability of LNG ship navigation accidents and accident haza...

The invention discloses a method for determining the navigation safety field of an LNG ship. The method comprises the steps of firstly, analyzing navigation characteristics and navigation risks of theLNG ship; extracting main influence factors in the field of LNG ship navigation safety; and finally, constructing an LNG ship navigation safety field range calculation model. Quantitative research onthe range of the LNG ship navigation safety field is achieved, and a new thought and a new method are provided for research on the LNG ship navigation safety field; the model comprehensively considers the influence of the factors of the LNG ship and the navigation environment conditions, has good adaptability, and can provide technical support for the safety supervision of the port competent department on the entry and exit of the LNG ship into and from a port; the navigation safety of the LNG ship in a port water area can be guaranteed, the navigation order of a navigation channel is maintained, and reference and technical support are provided for the traffic organization for the entry and exit of the LNG ship into and from the port and navigation management of the LNG ship.
Description
technical field [0001] The invention belongs to the technical field of water traffic safety, and in particular relates to a method for determining the navigation safety field of LNG ships. Background technique [0002] In the 1960s, Japanese scholar Fujii proposed the concept of the ship domain. This area is based on the idea of collision avoidance and proposes a water area around the ship that prohibits other ships from entering. In terms of ship research, the relevant theoretical methods are relatively mature. The main methods include: methods based on statistics, methods based on analytical expressions and methods based on intelligent technology. However, in terms of factors affecting the ship field, considering that the comprehensive research on factors such as people, ships, and the environment is relatively complicated, it is difficult to describe some of the influencing factors quantitatively, and it is difficult to accurately express the relationship between the in...
