    Mixed Methods Research (MMR)
    Opis:
    The paper argues for the necessity of a combination MMR methods (questionnaire, interview) and sentiment/opinion techniques to personal satisfaction analysis at the maritime and training education and proposes a generic, but practical research approach for this purpose. The proposed approach concerns the personal satisfaction evaluation of Engine Room simulator systems and combines the speech recording (sentiment/opinion analysis) for measuring emotional user responses with usability testing (SUS tool). The experimental procedure presented here is a primary effort to research the emotion analysis (satisfaction) of the users-students in Engine Room Simulators. Finally, the ultimate goal of this research is to find and test the critical factors that influence the educational practice and user’s satisfaction of Engine Room Simulator Systems and the ability to conduct full-time system control by the marine crew.

    Opis:
    The EC funded CyClaDes research project is designed to promote the increased impact of the human element in shipping across the design and operational lifecycle. It addresses the design and operation of ships and ship systems. One of the CyClaDes’ tasks is to create a crew-centered design case-study examination of the information that is shared between the Bridge and Engine Control Room that helps the crew co-ordinate to ensure understanding and complete interconnected tasks. This information can be provided in various ways, including communication devices or obtained from a common database, display, or even the ship environment (e.g., the roll of the ship). A series of semi-structured interviews were conducted with seafarers of diverse ranks to get a better idea of what communication does, or should, take place and any problems or challenges existing in current operations, as seen from both the bridge and ECR operators’ perspectives. Included in the interview were both the standard communications and information shared during planning and executing a voyage, as well as special situations such as safety/casualty tasks or heavy weather. The results were analyzed in terms of the goals of the communication, the primary situations of interest for communication and collaboration, the communication media used, the information that is shared, and the problems experienced. The results of seafarer interviews are presented in the paper to explore on-board inter-departmental communication.

    Opis:
    Maritime safety involves minimizing error in all aspects of the marine system. Human error has received much importance, being responsible for about 80% of the maritime accident worldwide. Currently, more attention has been focused to reduce human error in marine engine maintenance. On-board marine engine maintenance activities are often complex, where seafarers conduct maintenance activities in various marine environmental (i.e. extreme weather, ship motions, noise, and vibration) and operational (i.e. work overload and stress) conditions. These environmental and operational conditions, in combination with generic human error tendencies, results in innumerable forms of error. There are numerous accidents that happened due to the human error during the maintenance activities of a marine engine. The most severe human error results in accidents due to is a loss of life. Moreover, there are other consequences too such as delaying the productivity of marine operations which results in the financial loss. This study reviews methods that are currently available for identifying, reporting and managing human error in marine engine maintenance. As a basis for this discussion, authors provide an overview of approaches for investigating human error, and a description of marine engine maintenance activities and environmental and operational characteristics.

    Opis:
    Maritime transportation is the essence of international economy. Today, around ninety percent of world trade happens by maritime transportation via 50,000 merchant ships. These ships transport various types of cargo and manned by over a million mariners around the world. Majority of these ships are propelled by marine diesel engines, hereafter referred to as main engine, due to its reliability and fuel efficiency. Yet numerous accidents take place due to failure of main engine at sea, the main cause of this being inappropriate maintenance plan. To arrive at an optimal maintenance plan, it is necessary to assess the reliability of the main engine. At present the main engine on board vessels have a Planned Maintenance System (PMS), designed by the ship management companies, considering, advise of the engine manufacturers and/or ship’s chief engineers and masters. Following PMS amounts to carrying out maintenance of a main engine components at specified running hours, without taking into consideration the assessment of the health of the component/s in question. Furthermore, shipping companies have a limited technical ability to record the data properly and use them effectively. In this study, relevant data collected from various sources are analysed to identify the most appropriate failure model representing specific component. The data collected, and model developed will be very useful to assess the reliability of the marine engines and to plan the maintenance activities on-board the ship. This could lead to a decrease in the failure of marine engine, ultimately contributing to the reduction of accidents in the shipping industry.

    Opis:
    The greatest vibration occurs in the engine room, but all other parts of the ship also experience vibrations because it is propagating. Even though there are methods to reduce these vibrations such as engine beds, they can only reduce the damaging effects and cannot completely eliminate the vibrations themselves. The method used in this research is to compare the measurement of good vibrations in the conditions before the addition of construction and after the addition of construction for later comparison with numerical calculation data. The purpose of this study is to obtain the maximum vibration value in the conditions after the addition of the gorger construction before the addition of the side deck girder construction as a means of evaluating the side deck girder construction planning in the ship engine room ship 2000 DWT. The result consideration of adding construction becomes one or the alternative in providing reinforcement so that it can reduce the vibration that occurs. From analyze results after addition of a sized T profile FB 180 x 8 mm FP 75 x 10 mm, which ranges from 28 - 29 m/s2 for the x-axis vibration value, while for vibrations on the y-axis the maximum is 10-11 m/s2, and on the maximum z-axis. at 20-21 m/s2, this analyze vibration is based on the time between 0 - 15 seconds or per 15 second interval, able to reduce percentage of vibration in the ship engine room area is 34.91%.

    Opis:
    A The novelty of this study consists in the fact that, at the same time as the monitoring and acquisition of data of the air quality (from inside and outside), a monitoring and acquisition of data of the real-time biometric measurements of subjects exposed directly to the needle will be made. Medium by means of a bracelet attached to the subject's arm. This bracelet is designed to perform biometric measurements without creating discomfort to the subjects analyzed in the activities in which they are involved. This measurement is carried out with 9 different sensors for: pulse, oxygen in the blood, air flow (breathing), body temperature, electrocardiogram, galvanic skin response, blood pressure, the patient's position/movement, and the status of muscle (electromyography sensor). The data thus obtained will be focused on a PC and subsequently analyzed. The results of monitoring the health parameters of the subjects analyzed find application in the maritime field, to ships, especially in the engine room, where the air suffers quality transformations. The crew's return to the workplace may decrease due to the degradation of the air quality in the premises.

    Opis:
    Shipping can be regarded as a high-risk domain with a large complexity in operations. Accidents and incidents may involve serious danger for seafarers and passengers, as well as for the environment and society at large. Education and training play a crucial role for the safe conduct of ships. While technical skills have been at the core of a mariner’s skillset, non-technical skills (NTS) have become increasingly important for the safe conduct of merchant vessels. Therefore, knowledge in NTS has become a mandatory requirement for officers serving on board. This knowledge is normally taught in courses labelled Bridge Resource Management, Engine room Resource Management, or Maritime Resource Management. While the number of courses in the industry is steadily increasing, research focused on NTS training and its relation to safety in operation seems sparse. This review article aims to provide an overview of scientific literature focused on training NTS for maritime operations published between 2000 and 2018. Based on the reviewed literature the article identifies and discusses current research gaps, trends and potential future directions to improve maritime resource management training.

    Opis:
    The main propulsion engine is the heart of a vessel which carries the entire load of the ship and propels to move ahead. The main engine consists of various sub-systems, the fuel oil system is the most important one. Fuel oil system provides fuel to the engine via a fuel injector mounted on the engine cylinder head. During the voyage, the main engine of a ship encounters a variation in loads and stresses due to rough weather to harsh manoeuvring, which sometimes leads to the breakdown of the main engine. Fuel oil systems are identified as one of the main reasons for engine breakdown. Many accidents happened due to the failure of the main engine fuel oil system in the last two decades. To ensure safe and reliable main propulsion engine operation, it is required to assess the reliability of a fuel oil system. However, there is a significant lack of appropriate data to develop the reliability assessment techniques for fuel oil system. This study proposes appropriate data collection and analysis procedure for the reliability assessment of a fuel oil system. Data related to Failure Running Hours (FRH) of a fuel oil system is collected from 101 experienced marine engineers through a questionnaire. The collected data processed using a box plot and analysed for a normality test. It helps to identify the generalization of the data. Moreover, this study identified failure-prone components of a fuel oil system. The collected data will help in developing reliability assessment techniques for accurate reliability analysis of a fuel oil system. The identified failure-prone components will assist in future reliability analysis and risk mitigation strategies for improving the overall safety and reliability of the shipping industry.
