Description

Technical Field

[0001] The present invention relates to the technical field of water traffic safety supervision, and in particular to a water traffic safety risk classification management and control system and method. Background Art

[0002] Water traffic safety risk refers to the combination of the possibility and consequences of water traffic accidents that occur during the navigation, mooring and operation of ships or facilities. It is a subjective evaluation of the possibility of water traffic accidents and the severity of their consequences. The water traffic safety risk level is divided into four levels from high to low, according to the possibility and severity of accidents that may occur, namely major risk, greater risk, general risk and lesser risk.

[0003] In recent years, the transportation industry has continuously strengthened the prevention and resolution of production safety risks and the investigation and management of hidden dangers, and has achieved phased results. However, accidents (incidents) in the field of water transportation still occur from time to time, exposing that the production safety risks of transportation have not been effectively controlled. At the national level, the current management of water transportation safety risks still has the following drawbacks:

[0004] (1) There is a lack of unified risk level determination methods and rules, and the scientificity and accuracy of risk level determination results are not high. Different managers or institutions make risk level determinations based on their own understanding and experience, resulting in the same risk source being determined as different risk levels under different circumstances. It is difficult to make horizontal and vertical comparisons and evaluations of risk level determination results in different regions and at different times, and it is impossible to form an effective risk management mechanism. The inconsistency of risk level determination results may make it difficult for decision makers to make scientific and reasonable decisions, which in turn affects the overall effect of water transportation safety management.

[0005] (2) There is a lack of unified risk data management standards, no unified visualization, intelligent risk assessment and management software, and a low level of informatization and intelligence. The risk assessment process relies on manual experience and judgment, and it is difficult to ensure accuracy and consistency; the existing software lacks visualization functions, making it difficult to present risk data intuitively, which is not conducive to decision makers making quick decisions. They are not aware of the current security situation and are unable to recognize the existing risks; the allocation of risk supervision resources has no objective basis, which has become a bottleneck for the transformation of the water transportation safety governance model to pre-emptive prevention.

[0080] Among them, the ship activity waters are divided based on functional waters, including: navigable waters, mainly waterways and other ship navigation waters; facility waters, mainly waters with obstructions such as water and underwater construction areas, bridge waters, pipeline waters, etc., which are very likely to cause accidents; berthing waters, mainly docks, anchorages and other waters where ships are moored. The ship types are mainly aimed at the regional ship operation status, including high-speed passenger ships, ordinary passenger ships, dangerous goods ships, container ships, ordinary cargo ships and other ship types. The ship activity / operation type refers to the activities or operations of ships entering and leaving the port in the region, which are divided into: ship navigation, ship berthing (including ship berthing, mooring, shifting, etc.), ship construction operations, ship loading and unloading operations (including ship loading or unloading operations, tank cleaning or tank washing operations, oil supply and receiving operations, crude oil tank washing operations, pollutant receiving operations) and other situations.

[0081] Potential risk events are identified based on risk identification parameters. The potential risk events are mainly divided into: collision and capsizing risks; reef and grounding risks; contact risks; wave damage risks; fire and explosion risks; wind disasters or typhoon prevention risks; self-sinking and sinking risks; leakage and pollution risks; and other risks according to the relevant regulations of the water traffic accident statistics method.

[0082] 2) Risk factor indicators and weight allocation units;

[0083] The risk-causing factor indicator and weight configuration unit is used to provide a risk-causing factor indicator and weight configuration interface to configure the risk-causing factor indicators and weights of potential risk events, and obtain the risk factors of potential risk events based on the risk-causing factor indicators and weights; configuring the risk-causing factor indicators and weights includes: for risk events, selecting risk-causing factor indicators from aspects such as human factors, ship factors, material factors, environmental factors and management factors, and configuring indicator weights for the risk-causing factor indicators.

[0084] Among them, human factors mainly analyze the competence, safety awareness, safety and emergency skills, safety behavior or status of employees, including: crew members have not obtained a certificate of competence, crew members do not comply with navigation rules or safety operating procedures, crew members do not comply with cargo loading and unloading operation specifications, crew members are insufficient and other risk factors. Ship factors mainly analyze the conditions of the ship's mechanical equipment, hull structure and strength, maneuverability, cargo loading and lashing. Material factors mainly analyze factors related to the cargo carried by ships, such as the hazard of cargo, cargo volume, cargo transportation methods and other risk factors of cargo. Environmental factors mainly analyze the conditions of the ship's movement, including the natural environment, navigation environment, navigation order and working environment. Management factors mainly analyze management factors such as competent authorities, ship owners, operators or managers, port enterprises, construction units, etc.

[0085] Based on the risk factor indicators and weights, the risk factors that lead to potential risk events are found, and the possible consequences and adverse effects caused by the risk factors leading to the risk events are analyzed to obtain risk identification results.

[0086] 3) Risk severity matching unit;

[0087] The risk severity matching unit is used to automatically match the severity level of a potential risk event according to the severity of historical events, and assign a risk severity value to the event; and the system provides a manual verification and modification function. When the risk severity value differs from the user's perception, the user can modify the risk severity value and fill in the basis for the modification.

[0088] 4) Risk level determination calculation unit;

[0089] The risk level determination calculation unit is used to obtain static risk and dynamic risk values ​​based on the risk factors and risk severity values ​​of potential risk events, and determine the risk level based on the size of the risk value to achieve risk level determination, obtain the risk level determination result, and store the risk level determination result in the data storage unit.

[0090] like Figure 2 As shown, the risk determination module determines the risk level of the pre-processed risk data according to the risk level determination method, including risk identification of the pre-processed risk data to obtain potential risk events and risk factors; risk assessment of the potential risk events to obtain the risk level of the potential risk events; based on the risk type, risk level and risk factors of the potential risks, the level of risk control measures is determined, thereby realizing risk hierarchical control;

[0091] ① Risk identification includes: the risk identification parameter configuration unit divides the pre-processed risk data into corresponding risk identification units (the risk identification unit corresponds to the spatial position, and the main purpose of the risk identification unit division is to refine the location of the risk event for the convenience of standardized management), and in each risk identification unit, the flowchart method is used to investigate and analyze each stage and each link of the ship's entry and exit process one by one, and discover and determine potential risk events according to the risk identification parameters; and the risk factor index and weight configuration unit comprehensively considers the risk factor index and weight to find out the risk factors that cause the risk event, analyzes the possible consequences and adverse effects after the risk factor causes the risk event, so as to obtain the risk identification results, and the risk identification results include potential risk events and risk factors of potential risk events.

[0092] Among them, the risk identification unit division can divide the pre-processed risk data into appropriate risk identification units according to regional supervision characteristics, ship operating environment, ship speed under different environments, conditions required for rescue operations in the event of an accident, and possible environmental pollution; risk identification units are divided into management grids, responsibility grids, and unit grids from large to small. The management grid is based on the basic framework of water traffic safety supervision, with grassroots management agencies as the basic management entity units, and its management scope is a management grid; the responsibility grid is the corresponding responsibility area delineated by each grassroots management agency according to the characteristics of regional waters, supervision characteristics and ship traffic characteristics. For the responsibility grid, specific supervision resources and supervision responsibilities need to be clarified, and a management grid can be divided into multiple responsibility grids; the unit grid corresponds to the smallest risk identification unit, and functional waters are used as unit grids. Multiple unit grids with similar functions constitute a responsibility grid.

[0093] Identifying potential risk events refers to determining possible risk events based on risk identification parameters (such as different ship activity waters, based on ship types, ship operations / activity types), combined with the actual situation of daily production safety management, and comprehensive consideration of historical risk events within the jurisdiction; analyzing risk factors refers to comprehensively analyzing the impact of risk factor indicators and weights (such as human factors, ship factors, material factors, environmental factors, and management factors) on risk events.

[0094] ② Risk assessment includes: the risk level determination calculation unit conducts assessment from two dimensions, static risk and dynamic risk, for potential risk events after risk identification, based on the static risk assessment timing (static risk assessment timing refers to regular assessment, with an annual, quarterly, monthly or periodic cycle) and the dynamic risk assessment timing (dynamic risk assessment timing is a quasi-real-time assessment, generally in hours), to obtain the risk level of the potential risk event; and determines the change in risk level based on the risk assessment results; that is, the risk assessment includes static risk assessment and dynamic risk assessment;

[0095] Among them, static risk assessment is also called regular risk assessment. According to the characteristics of regional supervision and changes in water transportation, risk assessment is conducted regularly on an annual, quarterly, monthly or periodic basis to adjust the overall risk level of the risk identification unit in a timely manner.

[0096] The static risk assessment selects different risk factor indicators, and the risk severity matching unit analyzes the possibility of occurrence of different risk factors and the severity of the risk events that may be caused to obtain the risk severity value; the risk level determination calculation unit uses the risk assessment matrix method based on the risk severity value to obtain the static risk value of the region. The static risk value is expressed by the following formula:

[0097] R=L×S

[0098] In the formula, R is the static risk value; L is the risk probability value; S is the risk severity value.

[0099]

[0100] In the formula, L is the risk probability value; m is the number of first-level indicators; n is F x1 The corresponding number of second-level indicators; Q x1 , F x1 Respectively represent the weight and score of the xth indicator in the first layer; F y1 , F y2 , …, F yn They respectively represent the scores of the 1st to nth indicators in the second layer.

[0101] The risk probability value is determined by the possibility of the risk factor. According to the actual situation of the risk factors in the region, different functional areas adopt different risk probability assessment indicators in accordance with the principles of representativeness, independence, relativity, quantification and data collection. The risk probability assessment indicators, indicator weights and scores can be adjusted and supplemented according to the actual situation of the region.

[0102] The risk severity is divided into four levels: not serious, relatively serious, serious, and extremely serious, with values ​​ranging from 1 to 10. Based on the situation of key regional regulated ships, the maximum casualties, economic losses, environmental pollution, and social impact that may be caused after the risk event occurs are analyzed, and the consequences and losses of similar events in history are comprehensively referenced for decision making.

[0103] Dynamic risk assessment means that when changes are detected in the risk factors that affect water transportation safety, it is necessary to conduct dynamic risk assessment and adjust the dynamic risk level of the risk identification unit in real time.

[0104] The dynamic risk assessment is based on the characteristics of regional safety supervision and risk impact, adopts a fuzzy comprehensive evaluation method, and follows the following principles to determine the risk level and obtain a dynamic risk value; including: 1) One-vote veto principle: When certain indicators reach or exceed the critical value of ship navigation and operation safety, such as when the wind force reaches level 10 or above, the regional risk is directly adjusted to a major risk; 2) Indicator promotion principle: Among all the evaluated indicators, if there are many indicators close to the critical value of navigation and operation safety, under the joint effect of multiple indicators, the risk situation is relatively dangerous at this time, and the risk situation is directly adjusted to a major risk; 3) Special classification principle: For major water activities and sudden water traffic incidents, special risk classification principles can be formulated according to management needs.

[0105] The fuzzy comprehensive evaluation method uses weighted evaluation, in which the weight coefficient is represented by a fuzzy weight vector, and the score of the factor is represented by an evaluation matrix; combined with the regional characteristics of the jurisdiction and the quantifiability and accessibility of the indicators, the regional dynamic risk assessment indicator system is determined from several dimensions such as personnel skills and comprehensive quality, ship entry and exit status, ship traffic flow, visibility, wind, and shipping company management level.

[0106] ③Risk control includes: determining the level of risk control measures based on the risk type, risk level and risk factors of potential risk events (the level of risk control measures is equivalent to a catalog or category of control measures, which can clearly define the dimensions from which risk control measures are determined, so that the risk measure dynamic matching unit can match the corresponding measures later), scientifically formulating targeted control measures, clarifying the risk responsible parties and regulatory bodies, and limiting risks within preventable and controllable ranges, thereby achieving risk hierarchical control.

[0107] The risk control measures include three levels: key technologies and engineering measures, personnel quality and system management measures, and individual protection and emergency management measures. Among them, the key technologies and engineering measures mainly refer to the basic technical requirements and control measures for making ships seaworthy, crew members competent, and cargo suitable. Ships, crew members on board, cargo loading, water facilities, shipping containers, important marine equipment, components and materials comply with the requirements of the International Maritime Organization and domestic laws, regulations, administrative regulations, and mandatory standards and technical specifications. The personnel quality in the personnel quality and system management measures mainly includes personnel quality skills, operating procedures, management systems, etc. System management measures include establishing an organizational system, clarifying the responsibility system, establishing a system system, regularly conducting safety risk assessment, and conducting risk monitoring and early warning. Individual protection in the individual protection and emergency management measures includes the provision of protective equipment as required, such as lifeboats, lifebuoys, safety helmets, safety belts, protective clothing, etc.; the emergency management measures include the formulation of emergency plans and on-site disposal plans, the provision of emergency equipment, emergency duty, emergency evacuation, emergency drills, etc.

[0108] Risk classification and control follows the principle of "classified control, comprehensive internal and external management" and adopts corresponding levels of risk control measures for different risk types according to risk levels and risk-causing factors.
