The collision and sinking of “Sanchi” in 2018 is the first accident in the world shipping history in which an oil tanker carrying “condensate” was collided and caught fire. Due to the continuous volatility and flammability of condensate, rescue is relatively difficult. In addition, the oil film continued to spread on the sea, and the difficulty of control and cleaning is relatively high. All of these lead to a greater impact on human life, environment and economy, which has sounded an alarm for China's emergency response ability of hazardous chemicals accident. In this paper, based on the background of hazardous chemicals accident at sea, the basic principles of rescue helicopter participating in such rescue missions are discussed, and the relevant suggestions for the development of the industry are put forward.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116828284","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For inland vessels, speed optimization is an important method for energy efficiency improvement. Different from seagoing ships, the navigation environment has an important influence on the ship resistance when building the prediction model of main engine fuel consumption. The main influencing factors are channel depth, channel cross-sectional area, and wind speed. In this paper, considered the influence of various navigation environment factors, and combined with the Holtrop-Mennen method, a prediction model of inland vessel resistance has been established. Based on this model, combined with the ship-engine-propeller matching and the power-fuel consumption curve of the main engine, the prediction model of the main engine fuel consumption is established. The shuffled frog-leaping algorithm is used to optimize the speed with the minimum fuel consumption of a single voyage as the objective with constraints of the engine speed, ship speed, and total sailing time. Then, the route is divided into several segments based on geographical region. The simulation results show that the ship speed optimization is effective.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126006908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper, three types of treatment technology of ship exhaust gas, i.e. pre-treatment technologies, in-cylinder control technologies and post treatment technologies, have been introduced. Various single post-treatment technologies for the control of ship exhaust gas pollutants emission, including marine scrubber, selective catalytic reduction (SCR) and carbon capture and storage (CCS) were reviewed. The advantages and limitations of various post-treatment technologies of Sox, NOX and COx were analyzed. In practice, single pollutant treatment technologies were not effective for ship exhaust emission reduction. The development of new desulfurizers, the optimization of integrated process flow, feasibility of the system operation, could be the future direction of ship exhaust post-treatment technology. There are two restrictions for the development of the ship exhaust treatment technology, which are the space limit and the cost requirements.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126120458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the low-speed and heavy-load working condition, the thrust bearing faces the risk of abnormal wear and failure, and the failure mode and mechanism are still unclear. Taking the thrust bearing with aluminum bronze thrust collar and PEEK fixed pads as object, 48-hour accelerated wear test were carried out under four working conditions on the water-lubricated bearing test bench. The surface topography features of the pad and thrust collar are extracted before and after wear. The variation law of the friction coefficient, temperature difference between the inlet and outlet water, vibration signal, and floating amount of the thrust collar with time are studied, and the failure mode and mechanism of the bearing are analyzed. The results show that the PEEK-aluminum bronze friction pair wears severely under low-speed and heavy-load conditions, and the failure mode changes from adhesive wear to abrasive wear. The cuneiform water film is formed on the center of the pad surface, which is the main load region. It is difficult to form a water film near the inner and outer diameters of the pad, resulting in obvious ablation and plastic deformation, and the overall pad surface is concave. The maximum temperature difference between the inlet and outlet water is 14.2 °C, but the instantaneous high temperature that carbonizes the PEEK material appears on the pad surface. The traditional water temperature monitoring methods are difficult to reflect the working status of the water-lubricated bearing. The sudden change in amplitude at the feature frequency of 13500 Hz indicates that the bearing will deteriorate rapidly, and the impulse factor and waveform factor in the time domain feature can well characterize the degradation trend of the bearing.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124678565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This problem can be solved by flexibly using signal priority control to improve bus traffic efficiency. With the emergence and development of V2X technology, it provides more real-time and accurate data for real-time TSP control technology, and provides new ideas for TSP, a multi-level priority adjustment strategy based on a V2I single intersection is proposed in this paper. Priority vehicles issue a priority peer request before entering the intersection, and the roadside decision unit combines the signal light information to comprehensively decide it as a priority vehicle preemption signal. In this paper, the range of signal preemption control adjustment expended by compressing the green light duration of multiple adjacent stages. and the real-time preemption efficiency of the continuous priority request vehicle is improved. The strategy we promote has taken the maximum and minimum green light traffic time to ensure the traffic safety of the intersection. The simulation experiment results show that the transit delay of public transportation vehicles can be reduced by 54.6%, overall delay of the intersection will not increase significantly, which proves the effectiveness of the strategy we promote.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129404812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this paper proposes a ship motion mathematical model in the ship lock waterway. Based on a ship mathematical model group (MMG) model, the factors of low speed and shallow water effect are considered in the proposed model. Then, the force field is calculated by the bank effect, and uniform flow and steady wind model is introduced to calculate the hydrodynamic forces acting on the ship. The trajectories of the ship straightforward sailing and turning motions under different water depths and draft ratios with the proposed model are compared. The results show that as the water depth decreases and the environment interferes, the maneuvering ability of the ship decreases. The model can reasonably express the ship motion characteristics in the lock waterway and be the basis of ship motion prediction and control in ship lock waterways.","PeriodicalId":253824,"journal":{"name":"2021 6th International Conference on Transportation Information and Safety (ICTIS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128284291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
