    This paper investigated the opportunities and challenges of integrating ports into hydrogen (H2) supply chains in the context of Australia and Japan because they are leading countries in the field and are potential leaders in the upcoming large-scale H2 trade. Qualitative interviews were conducted in the two countries to identify opportunities for H2 ports, necessary infrastructure and facilities, key factors for operations, and challenges associated with the ports’ development, followed by an online survey investigating the readiness levels of H2 export and import ports. The findings reveal that there are significant opportunities for both countries’ H2 ports and their respective regions, which encompass business transition processes and decarbonisation. However, the ports face challenges in areas including infrastructure, training, standards, and social licence, and the sufficiency and readiness levels of port infrastructure and other critical factors are low. Recommendations were proposed to address the challenges and barriers encountered by H2 ports. To optimise logistics operations within H2 ports and facilitate effective integration of H2 applications, this paper developed a user-oriented working process framework to provide guidance to ports seeking to engage in the H2 economy. Its findings and recommendations contribute to filling the existing knowledge gap pertaining to H2 ports.

    Abstract Work in the engine department is currently demanding more monitoring task. However, the current alarm systems that support operators during troubleshooting are deficient. In many cases, operators reach the engine control room (ECR) only to find a false alarm. This problem is likely to aggravate in the future as operators work in smaller numbers or even alone; therefore, task prioritization should be considered in a given context. Therefore, this study examines the application of head-worn displays in engine resources management to improve situational awareness (SA), trust in automation, and workload. A human-subject experiment was conducted using an engine plant simulator. The participants simultaneously performed maintenance and monitoring tasks in two scenarios: work conditions assisted with and without information on the head-worn display used as a cognition aid. Subjective measurement involved filling in questionnaires after each trial, whereas objective measurement used the simulator-recorded data. The results show that the availability of engine parameters and alarm indicators on a head-worn display is less significant in improving situational awareness. However, it can still help develop trust in automation and lower the workload. In addition, head-worn displays improve participants’ prioritization in a multi-tasking environment. The results indicate that examining these findings in actual work environments can help realize the future application of head-worn displays in ship operations.

    Abstract Recent development and projection of ship operations as a sociotechnical system is getting more complex. In order to successfully emulate a high-reliability organization with a balance between operational efficiency and safety, the shipping companies have to grab a well understanding of the operating performance. However, because the teams are distributed spatially and temporally, a misalignment of shared situation awareness casually exists. We extended Rasmussen’s dynamic safety theory and adjusted it in the context of ship management performance. A modelling study using system dynamics was done to illuminate how the feedback loops construct the interaction between safety, efficiency, and workload. The simulation result shows that the operations behave following the safety and efficiency pressures created by existing goals and boundaries. The model is also able to capture these trade-offs in different variety of operation scenarios. Application such modelling may provide the managers with a better understanding and valuable insight to implement the strategies to sustain safe operations.

    International convention on Standards of Training, Certification and Watch keeping for seafarers (STCW) was amended in Manila, the Philippines in 2010. The amendments will come into force on 1 January 2017. To meet the competence requirements for marine engineers, the implementation of Engine-room Resource Management training (hereafter, ERM training) was adopted as mandatory. The role of a practical ERM training model has become more important for marine engineers working in a complex system. The purpose of this study is to examine which ERM training best suits engine-room simulation education. First, in this paper, the characteristics of total human errors were investigated using 298 marine accident records from the Japan Marine Accident Inquiry. Second, the common factors of these accident records, namely the latent factors, were determined using covariance structure analysis. Furthermore, System Dynamics (SD) was employed to find the relationships between the latent factors and the technical support to gather the clues for a practical ERM training method. The model includes a data set of actual cases from records of marine accident inquiries and a hypothetical data set. The results show that the support of the onshore management and behavior characteristics of engineers which influence each other in a delicate balance could be expressed in a chronological order.

    The role of marine engine accident prevention has become more important for marine engineers working in a complex environment. Various risk factors caused by human errors result in serious accidents. However, this argument does not account for the relationship between error and accident. The purpose of this study is to introduce an integrated multi-dimensional approach to investigate errors committed by engineers. For this work, the characteristics of total human errors were investigated by taking 298 marine accident records from the Japan Marine Accident Inquiry and 104 incident records from engine trouble casebooks. Different incident records are compared by employing quantification theory III, which is one of the measurements for multivariate analysis. This research identifies actualized and latent events by using accident records and incident records without near-accidents. Furthermore, the authors present recommendations for safety guidelines required for safe engine operation by analyzing both compositions of factor and total image errors.

    Main engine inspection and maintenance are important tasks carried out by the engine crew. Nevertheless, a case example where carelessness such as the failure to properly lubricate the connecting rod bolt led to insufficient bolt clamping which eventually resulted in engine damage has been reported. Since it is important that uniform standard procedures for bolt tightening be equally adopted in all ships, the authors sent out questionnaires regarding bolt tightening practices and procedures to marine engineers who work for Japanese shipping lines. The results obtained from the responses of 85 engineers showed that there are multiple views regarding bolt tightening managements, such as the type of lubricant used, the method of lubricant application, and the method of tightening for bolts in the same engine part.

    A test hammer is used to detect faulty components or slack bolts during impact inspection of marine diesel engine cranks. Since a prolonged work experience is necessary to acquire this technique, technology transfer is therefore difficult. Moreover, because this technology depends on the individual senses, the inspection accuracy is prone to vary among people. The authors have developed a system that can perform the above-described inspections and execute diagnostic procedures and thereby be more useful than human acoustic sense. We constructed an algorithm that estimates the fastening force of a crank-pin bolt at a connecting-rod large-end from sound, with which diagnostic tests were conducted. However, this algorithm is for a specific bolt only and is inapplicable to bolted joints of various types. This study conducted impact experiments using test pieces with varied component size and bolt tightening torque. First, the test piece size was estimated from impact sound data using discriminant analysis. That result was subjected to multiple regression analysis, a technique of multivariate analyses, from which the bolt tightening torque was estimated. The introduction of this two-step analytical method has provided us with a new tightening torque estimation algorithm for application to various bolted joints.

    Safe operation of a ship engine plant is maintained using a continuous monitoring system and periodic inspection and maintenance undertaken several times daily. When monitoring and maintenance work are executed to judge the state of equipment, an operator uses data from measurement instruments and detects the operating sound of an engine and the hammering sounds from contact using a testing hammer.
    The hammering inspection using the testing hammer, which is a general check method in routine maintenance work, is used not only for marine engines but also for various machines on land. In those machines, to prevent accidents, checking before engine starting is performed routinely, but many accidents caused by loose bolts and similar malfunctions are reported.
    For this study, an experiment was performed while the fastening power of bolts in the connecting rod was variously changed. Sounds generated when bolts are hit with the testing hammer were recorded at that time. An operator heard the hammering sound. The means by which the operator judged the fastening power by the hammering sound were investigated using a questionnaire. In addition, the hammering sound was made into data, and calculation of the fastening power was assessed using statistical analysis based on the above data. Consequently, a multiple regression formula with high accuracy was obtained for particular bolts used for this experiment. Results clarified that the fastening power can be estimated from the hammering sound.

    Troubles with a marine Diesel engine can occur unexpectedly, and regardless of the quality of maintenance. It can take much time to find the cause when a marine Diesel engine stops without any clear mechanical reason.
    It has been reported that huge amounts of sludge containing mycelia were found trapped on a marine Diesel oil strainer element; this causing the engine to stop because of the reduction of fuel supplying the engine. In this study we examine the contamination and the distribution of fungi - and their mycelia - in fuel oils loaded aboard and stored on an ocean going training ship. Fungi in the marine Diesel oil were discovered localized in the hull fuel tanks and in the settling tank of the engine room; the fungi had made mycelia.
    These results indicate the importance of the management of marine Diesel oil stored in a ship's tanks in order to avoid unexpected troubles with a main engine and/or generator engines. We also examined the lubricating oil temperature at the main engine outlet, which increased 50-55°C.
    Fungi could not be detected from the sample taken from the tank-pipe lubricating system, except in the settling tank. Since the lubricating oil in the settling tank was stored for more than ten years without use, the pH value had been reduced to about 6.0, indicating the importance of keeping the lubricating oils alkaline. Also, exposure to high temperature can prevent fungous growth.

    The efficient management of Marine diesel oil on board stands to gain from knowing the properties of the fungi which have an ability to grow in there. A fungus, which was isolated from the sludge trapped on the element in a strainer for Marine diesel oil, was able to grow in Marine diesel oil alone as well as in the chemically defined medium (CDM), pH 5.6 - 5.8, containing 0.1% glucose, 0.1% ammonium sulfate, and 0.1% potassium dihydrogenphosphate. When the isolate was grown in low oxygen concentrations of 0.5 -1.0% (vol/vol), the growth was repressed strongly in the eutrophic growth medium. In Marine diesel oil, however, the growth repression was not observed in the same oxygen concentrations described above in comparison with that in the aerobic condition. The growth in low oxygen condition seems to be limited by the quantity of the isolate in the medium. The isolate utilized n-tridecane and n-tetradecane as carbon and energy sources in CDM when glucose was replaced by these compounds. The reduction of n-tridecane and n-tetradecane in the CDM was found to be 98.8% and 92.3%, respectively, after 40 days of aerobic incubation, indicating that the isolate can utilize n-paraffms in Marine diesel oils.

    Growth of a fungus, which was isolated from the sludge at the bottom of a ship's fuel tank for Marine diesel oil, was examined. A lot of sludge had been stacked on the wire-mesh filter in the fuel strainer. In this ship, the commercially available dispersant, YUNIC #555D, was being used continuously to reduce the sludge formation in Marine diesel oil. The microscopic observation of the sludge revealed the mycelia of the fungus. The volume concentration of the dispersant in the sampled fuel oil containing sludge was estimated to be 1/300- 1/400, which was 25-67 times higher than that recommended by the company. This dispersant might have contributed to an increase in the growth of the isolate in Marine diesel oil. Hence we examined the additional effect of the dispersant on the growth of the isolate in Marine diesel oil. It was found that the isolate could grow in Marine diesel oil alone. Growth repression of the isolate, however, was observed even in the presence of 117100 of the dispersant as a final volume concentration. We examined another dispersant, SPA·LAZAE® that did not have any effect on the growth of the isolate.

    Training ship Fukae-maru of the Faculty of Maritime Sciences, Kobe University encountered the Typhoon No.16 (200416 CHABA) at Ikeda-bay of Syodo-sima in Seto inland sea on August 30, 2004. At that time, she evaded the crisis of dragging anchor twice. And the maximum instantaneous wind speed 61 meters were observed through this violent stormy weather. Our developing "Monitor System for Anchor Riding" detected the situation of the yawing movement of a ship in detail before and after dragging anchor. Then, the anchoring data that had been recorded with this system was analyzed and reproduced. The authors are expecting that this analytical result in high accuracy will be useful as one example concerning anchor dragging phenomenon in real ship under stormy weather.

    In order to improve the Engine-room Resource Management (ERM), the vital reactions and mental work load of the subjects who are supposing marine engineers were examined by simulated ERM environments in an engine room simulator. It was made clear that the mental work load of subject is able to be continuously estimated from the measurements of vital reactions by carrying out an appropriate pre-experiment for reference. The numerical simulation model was proposed to make clear the relation between engineers at sea and superintendents at head office in a viewpoint of "Understanding the present situation", "Choice of solving" and "Appropriate support" by utilizing the result of a previous work. The base to evaluate the delicate balance for Engine Resource Management under multiple management system was established in this activities.
