However, the number of ship accidents also increased. Ship accidents cause loss of life and property as well as environmental disasters. The occurrence of ship accidents causes enormous economic and environmental impacts. Especially, in case of passenger ships, methods for preventing ship accidents are being discussed to prevent losing numerous human lives. The purpose of this study is to provide basic data for evacuation before reaching the dangerous time by predicting the time to reach the risk of capsize based on the heeling angle of the passenger ship. Based on the sinking accident between 2012 and 2016, we set up specific scenarios and simulated the real-life data using commercial software MOSES V20. The simulation result is the heeling angle over time. We compared it with the simulation results using the linear equation. As a result of the comparison, a huge error was observed in the short time interval. Predicting the time of the equation reaching the hazardous angle was estimated in a similar fashion. It is expected that it will be possible to provide basic data for evacuation of human and ship by using nonlinear equations and improving the forecast’s accuracy.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"551 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115896115","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}

To accomplish the prediction of ship manoeuvrability with high accuracy using mathematical models for hydrodynamic forces acting on a ship, the values of hydrodynamic coefficients included in the mathematical model should have accurate values. Generally, ship manoeuvrability is evaluated by standard manoeuvring tests such as turning ability, course-keeping and yaw-checking abilities and so on. By investigating the sensitivity of each hydrodynamic coefficient on the results of the standard manoeuvring tests, it is possible to understand which coefficients should be mostly paid attention when they are obtained by numerical simulations. In this paper, sensitivity analysis of all the hydrodynamic derivatives using whole ship model is performed by using the conventional Monte Carlo Simulation (MCS) to evaluate the influence of coefficient on performance indices such as advance, transfer, tactical diameter and 1st and 2nd overshoot angles. The values of hydrodynamic derivatives are varied with the range of standard deviation which is assumed as 10% of their mean value. The results of simulation showed that which hydrodynamic coefficients have dominant effect on the performance indices of standard manoeuvring tests.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"313 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131647971","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}

Muhlbauer scoring system used in this approach i.e. third party damage index, corrosion index, design index, incorrect operation index, and leak impact factor. On the other hand, Fuzzy Inference System approach applied in the scoring system is Mamdani method (Max-Min) that includes the formation of fuzzy set, the implications of the application functions, composition rules, and defuzzyfication. The comparative results of both RSS approach are used as consideration to determine the next appropriate mitigation step for gas pipe 14 \"PT PHE-WMO. The calculation of pipe using fuzzy approaches provides greater difference value in RRs. The greater difference value of RRS makes it easy and clear in administering the rank for each segment of data input.

The jacket is launched into the sea by a barge. This study aims to determine the effect of initial launching conditions and analyze the jacket structure during the launching process. The initial conditions of barge trim and draft will be varied to determine the effect of these parameters on barge stability, separation time, rocker arm reaction, jacket bottom clearance, maximum barge trim and jacket strength. Overall 24 variations of initial barge trim and draft have been investigated. The results show that the minimum barge stability range is 49.02o, the minimum area ratio (K) is 12.16 and the minimum metacentric (GM) is 22.90 m. These values meet the limiting criteria of barge stability for launching process. Further, the effect of barge trim is found to be more significant than the draft on the separation time, rocker arm reaction, and maximum barge trim. The effect of barge trim and draft is not significant on the bottom clearance jacket.

The strait becomes a very important part of world freight transportation since it connects the shipping lane between East Asia, West Asia, Australia and Europe. Even though Traffic Separation Scheme (TSS) has been applied in the area to prevent the unlikely event of vessel collision, the number of catastrophic ship accident tends to increase by year. The Indonesian government plans to develop the ports located around SOMS. Such development increases the number of ships call per year which causes the ship traffic density in SOMS becomes more crowdy. This paper conducts an analysis on the vessel collision frequency influenced by the Indonesian ports development around waterway of SOMS including ports in Tanjung Pinang, Dumai and Batam Island. IALA Waterways Risk Assessment Program (IWRAP) is utilized to determine the annual frequency of head-on collision, overtaking collision and crossing collision. The Result of IWRAP modeling in this study shows that there is a significant increase of the future total ship collision frequency. The crossing collision contribute the most for the annual vessel collision, since there are higher number of ships cross the TSS caused by the development of Indonesian port around SOMS.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126359227","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}

Measuring the collision risk can be useful for navigator to maneuver the ship based on appropriate decision for collision avoidance. The process of collision between vessels can be expressed by predicting the point where the ship would be likely to meet and the collision may occurs using the geometry of the ship’s position. This study also utilized the ship trajectory to estimate the future position of the vessel and compared it with the predicted point in geometry calculation result. The collision risk will occur when ships meet in the same position in the same time based on the ship's movement prediction. Thus, the simplest model to evaluate the ship collision risk by using matrices and linear algorithm were performed. In this paper, Automatic Identification System (AIS) data is utilized and linear algorithm is employed to predict the ship movement. This study resulted the possibly position of collision and predicted the new coordinate’s position of the ship in t time. The proposed method can be considered as a first step to conduct collision avoidance and to improve navigation of ships in narrow and shallow waterways.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"144 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116372531","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}
