{"title":"Fire Risk Assessment for Piping System of LCT CNG Carrier","authors":"Munir Muradi, Bina Aji Nugraha","doi":"10.23977/mastic.006","DOIUrl":"https://doi.org/10.23977/mastic.006","url":null,"abstract":"Utilization of Natural Gas as a source of electrical energy is supported by the increasing of world electricity demand, especially Indonesia. Indonesia's geographical conditions, as archipelago country, provide challenges in the distribution of natural gas throughout the region. The distribution of gas from the gas source to the plant site requires an effective, efficient, and safe CNG Carrier. Some Landing Craft Tank (LCT) in Indonesia that is currently not functioned properly bring the idea to be utilized as one of the right choices as a CNG carrier. For conversion of LCT to CNG carrier must keep priority on safety aspect such as in the storage piping system. The piping system is highly vulnerable to explosion hazards caused by gas leaked. The released gas causes the piping system to have potential risks that need to be minimized. The fire risk assessment method is conducted under the BKI Reference Notes of Risk Assessment Applications for the Marine and Offshore Oil and Gas Industries, where the hazard identification is performed by using HAZOP (Hazard Operability). The HAZOP is performed by dividing the systems into several sub-systems. Released gas frequency is analysed using Fault Tree Analysis (FTA). As well as the accident analysis frequency of occurrence which will be scripted stage that gas released as the last order due to the malfunction order. Gas released near ignition source may lead to Flash Fire, Gas Dispersion and Gas Explosion. Using Event Tree Analysis (ETA) the frequency of occurrence will be calculated according to the impacts. Consequence analysis is then performed using the fire spread software. To represent the risk, F-N curve is used to determine the acceptance criteria classified into three conditions such as tolerable, in-tolerable and As Low as Reasonably Practicable (ALARP). The results obtained from this research are divided into two conditions is immediate ignition and nonimmediate ignition. in immediate ignition conditions, the risks are flash fire and gas explosion but in tolerable levels of risk. In Non-immediate ignition conditions, the risk is Flash Fire and Gas Dispersion in tolerable level of risk and non-immediate ignition conditions, gas explosion in ALARP level. The ALARP condition to be still at a safe level but some things of concern must be taken to cope or reduce the severity of the impact of the gas explosion. In ensuring the safety of the installation high pressure pipe CNG mounted it is necessary to note the safety provisions for the type of ship carrying gas above the deck including the hazardous area (cargo containment arrangement).

The aim of this study is the advancement of mathematical methods in the ship transportation field with relevance to collision avoidance scenario applications. The process of seafarers safely navigating a vessel at sea entails enacting appropriate decision-making at the appropriate time. In our model, we do not input the appropriate action order based on a seafarer’s experience. The model scores each step’s reward by its action behaviour and learns how to avoid obstacles by itself. By deploying decision timing, state, reward, and digitizing the seafarer’s decision, we establish a reinforcement learning algorithm based on Markov decision processes. In the model training, under a single factor influence, the vessel tends to change course with the best appropriate action behaviour, which is almost consistent with decision-making behaviour based on actual experience at sea.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"31 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":"134052190","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}

AIS is used as a navigational aid to ensure the safety of ship operation including collision avoidance, vessel tracking, and accident investigation. AIS Transponder is installed onboard ship and transmitted data will be received by the base station as AIS data receiver. AIS Transponder provides information for instance a unique identification, position, course, and speed. Then those data will be utilized for many applications. Ship’s movement information obtained from AIS such as position and heading can be utilized as an early warning to avoid the event of the collision. In some cases, ship heading data is unidentified caused by transponder incompatibility and mistakenly conducting setup of AIS transponder. To solve the problem, extrapolation method can be used to predict the ship’s heading. However, this method has the disadvantage since it only considers the location of ships while the distinctive area near the port is ignored. This paper aims to develop a method to predict the ship heading based on AIS historical data of ship’s movement using Artificial Intelligence (AI). Artificial Neural Network (ANN) has been chosen as AI prediction model. There are two pre-processing should do before training process such a down sampling and sliding window. Wide Genetic Algorithm (WGA) is used for ANN training process to create ANN model. WGA-ANN computes the ship heading by predicting the next geolocation of ship.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"3 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":"131047355","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}

The formal safety assessment method (FSA) was introduced by the International Maritime Organisation as a tool for decision-making process to ensure that action is taken before a disaster occurs. It will be adapted and applied in conjunction with pair wise comparison method and community survey. The objective is to determine the status of current navigation practices on Kenyir Lake, identify hazards and propose counter measure to enhance navigational safety. The study found that capsizing is the main Hazard and that standard operating procedures have high benefit cost ratio as a Control Option. Local authorities could consider these in their approach to enhance navigational safety practices on Kenyir Lake especially for tourism management and economic sustainability. Inland navigation in general will benefit from the application of FSA on navigation practices.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"82 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":"125880159","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}

The most common configuration for DF-DE is by using natural gases as main fuel but does not rule out the potential of other alternative fuel such as methanol. Methanol has potential application on board as low carbon, sulphur, NOX and particulate matter. Furthermore, it can produce with natural gas and biomass that has smaller emission from a life-cycle perspective. However, Methanol which classified as low flash point fuels (LFL), it has adverse effects including toxic, volatile and corrosive. This paper will specifically identify the potential hazard of methanol fuel system on board. Even though the further proposed design of Methanol fuel system is still not fully intact, the preliminary design is already developed and can be determined as a basis for hazard potency identification. The method for this identification is Hazard and Operability (HAZOP) which refers to BS IEC 61882:2001. With an expectation that the outcome from this identification can become the recommendation for further more detailed proposed a design for methanol fuel system.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"60 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":"127038660","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}

The type of seaport activities such as sailing, windsurfing, parasailing, fly boarding, canoes, are enjoyed by a growing number of Malaysians. As popularity increases, the numbers of accidents are growing rapidly. From the general observation, it showed that the awareness on safety aspects such as using proper equipment, suitable attire and enforcement of regulations are still lacking. All these issues have raised the concern to conduct a risk assessment on each sea sports activities. This research method was started with identifying the type of hazards for each sea sports activities by using HAZID method. Each of the hazards was individually analyzed and evaluated by using risk matrix in order to calculate the risk level. These risks obtained from this research are classified into four major classes which is General risk, Equipment (kit), weather and water. These classes states where the risk is initiated and what result does it contributed. The measurement level of severity of the injuries was sorting by the scale from one and to five and further analysis was made in the form of percentage. Result shows some of the activities may involve in minor and serious injuries. From the overall result, some of the most crucial hazards are drowning, head injury and other common injuries. Therefore, some of the recommendation were made as for prevention such as better supervision, maintaining good facilities and sport equipment and awareness on safety precautions of the sea sport activities.","PeriodicalId":200338,"journal":{"name":"Maritime Safety International Conference (MASTIC 2018)","volume":"12 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":"115614174","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}
