A simulation evaluation method for the effect of ship emergency collision avoidance action under imminent danger

Abstract

The invention provides a simulation and evaluation method for emergency collision steering action effects of ships in emergent danger. The method comprises the following steps: creating a three-dimensional simulation model for ship operations; according to the set scenes, initializing the external environment parameters; carrying out emergency processing training on the collision accidents of ship piloting people and acquiring the relevant parameter information of the ship piloting people in the emergency processing; according to the conditions of the external environment and the effects of the emergency operations, realizing the overall simulation and evaluation result of the emergency actions: according to the scene parameters, determining the difficulty coefficients of the set scenes; according to the initial parameter information of the ship and the parameter information prior to the collision, determining the evaluation parameters for the effects of the emergency operations; determining the evaluation effect of the emergency operations; multiplying the difficulty coefficients of the set scenes to obtain the overall simulation and evaluation result of the effects of emergency actions; and based on the problems existing in the emergency collision actions, proposing schemes for modifications. With the method, it is possible to make quantitative evaluations on the effects of people's emergency actions.

Description

technical field [0001] The invention belongs to the field of maritime simulation, and in particular relates to a simulation evaluation method for the effect of emergency collision avoidance actions of ships under imminent danger. Background technique [0002] According to the "1972 International Regulations for Preventing Collisions at Sea", ship collision avoidance is generally divided into four stages: free action, collision danger, urgent situation and imminent danger. At present, many researches at home and abroad focus on the first three stages. By assuming that the two ships can achieve good coordination, the ship collision avoidance simulation can be well realized. However, there are few studies on the fourth stage, that is, imminent danger. This is because the emergency action of the ship in imminent danger is to reduce the loss of the ship. The evaluation of the effect of the action cannot be based on whether the ship is safe to avoid, and its effect will be affecte...

Problems solved by technology

However, there are few studies on the fourth stage, that is, imminent danger. This is because the emergency action of the ship in imminent danger is to reduce the loss of the ship. The evaluation of the effect of the action cannot be based on whether the ship is safe to avoid, and its effect will be affected by the external environment. , the relative position and distance of the two ships, the initial encounter angle and other factors

[0003] In practice, due to the influence of the aforementioned multiple factors and the characteristics of offshore operations of ships, it is often difficult to use real ship experiments to improve the emergency response capabilities of personnel in emergency situations

The simulation technology provides a new way of thinking, because the simulation technology has the advantages of low test cost, high safety performance, low operation difficulty, and small organization difficulty, so it is widely used in ship maneuvering simulation. There is no better method for quantitative evaluation of emergency actions
