Study Of Risk Management In X Aids To Navigation Department Project Of Fixed Marking Maintenance

The maintenance project of fixed signs of X navigation mark office refers to the relevant departments of the navigation mark office maintain the fixed signs in the area according to the team structure,site and equipment of the current navigation mark office,the quality assessment standard for the maintenance of sea area navigation marks,the maintenance of sea area navigation mark fixed buildings,the management rules for the maintenance of sea area navigation marks and other relevant work requirements.Because most of the fixed signs are in the harsh and complex environment at sea,at the same time,the current maintenance project of the fixed signs at X navigation mark office is facing the situation of aging age structure of the team,insufficient maintenance site and personnel.Therefore,X navigation mark office is in strict accordance with the maintenance technology and process of the navigation mark to ensure the maintenance quality of the navigation mark to the greatest extent,which determines that the maintenance project of the fixed signs at the navigation mark has a relatively high quality big risk.To do a good job in the risk management of the project,we must accurately identify the risks in each stage and take effective and reasonable assessment methods and response measures to ensure the smooth completion.Based on the retrieval and analysis of risk management data of domestic and foreign navigation mark maintenance projects,combined with thebackground,nature and main characteristics of the maintenance project of fixed signs at X navigation mark office,this paper uses delphi risk identification method to identify that the project has five factors that affect the project construction,including external,quality,operation,progress and cost,from the possibility of risk occurrence and the final degree of impact from the point of view,the risk matrix assessment method is used to assess the five identified risks.Finally,the operational risk is extremely high,the quality risk and external risk are high,the schedule risk is medium,and the cost risk is low.According to the current assessment results and actual situation of the maintenance project of the fixed signs of the navigation mark office,X navigation mark office adopts risk prevention measures to deal with operation risks,adopts risk control measures to deal with quality risks and schedule risks,adopts risk avoidance and transfer measures to deal with external risks,adopts risk acceptance measures to deal with the cost risks.Through the systematic research on the maintenance project of fixed signs of X navigation mark office,the practical application of the theory and method of project risk management to the whole project is carried out,and the research methods suitable for the maintenance project of fixed signs of X navigation mark office are constantly summarized,hoping to provide a certain reference value for the operation of the maintenance project of fixed signs of later navigation aids offices.
