The Research On The Tugboat Operation Risk Assessment Of Tianjin Port

With the rapid development of the shipping economy and port construction, the vessels whichin and out of the tianjin port is increasing, vessel traffic flow density increasing, large scale, rapidness, on a ship hull form gradually tianjin port tug assignments are faced with more complicated situation. How to tianjin port on a ship to provide quality, safe, timely and economic services, tug on improve the image of the tianjin port shipping center in northern China, accurately grasp the tug operating risk source, take effective measures, make tianjin port tugboat operation is in safe and controllable range, reduce the frequency of tug operation accidents, reduce the tug operation accident of ship, roads tug itself and the harm of port handling facilities continuously optimize the tianjin port tug operation mode become an urgent problem to be solved.Tianjin port tugboat serviceco., LTD is a specialized tug services company, for passenger and cargo ships in and out of the tianjin port by drag from the top service, escort services, transport services and water fire protection, etc. Current research about tug job security risk is relatively small, with tugs on vessel operation in risk identification, risk evaluation, risk control theory research is also relatively small. Based on traffic flow density and tianjin port waters with tugs on vessel operation characteristic, according to tug barge in recent years, tianjin port tugboat service co., LTD. Work safety accident statistical analysis and tug safety control and operation risk analysis theory on the risk factors affecting the safety of tug homework system, comprehensive analysis, identification of tianjin port tug operation safety risk factors of the impact, hazards, such as universal evaluation significance of risk indexes, to determine the index weight, the hierarchical system of risk evaluation is established.First, this paper introduces the research background of this paper, the research purpose and meaning; Tug safety control and risk analysis of foreign and domestic research status; In this paper, the main research methods and contents, etc.; Navigation condition of tianjin port waters and tianjin tugboat service co., LTD., tug job scope and way are discussed in detail. Second, through the consult literature and combined with their own work experience, to tug on safety risk was analyzed, and preliminarily determines the impact of tianjin port tug operation risk source, through solicit opinions from the experts to determine the influence of risk source, to determine the impact on tianjin port tug operation safety of the main risk source and risk source of risk grade of a division, for the quantitative risk grade standard. Third, the use of analytic hierarchy process (ahp) to determine the impact tug operation safety indicators of risk weighting. Each risk index was determined by the expert investigation method for risk grade of membership degree, the fuzzy comprehensive evaluation method to establish the mathematical model of tianjin port tug operation safety risk analysis. Finally, according to the evaluation results of tianjin port tug job security recommendations, for in and out of tianjin port the ship’s captain and pilot construction provides a theoretical reference, for further optimizing the operation of tianjin port tug, and improve the level of tianjin port tug safe operation work provides a theoretical basis.
