Opis:: Project analysis to meet needs for equipment customized to pumping out surface forms of oil in the port and other narrow basins are reported in this paper. New elements of the technical concept of the skimmer to eliminate the disadvantages of structurally similar devices are proposed - esential componets of the new type of skimmer currently elaborating in the Student Scientific Society „Nautica“ (at Faculty of Marine Engineering of the Gdynia Maritime University) are demostrated. The first motivation to this work is that the consequence of growing usage of ships in the world transport is necessity to search for more fast and efficient methods to remove oil pollutions from the water surface and the second one – preparation of appropriate training and research equipment for the continuous improvement of its construction as well as the manner of its use in variety conditions. Port areas are relatively small and they have numerous hard to navigate places, therefore oils which leaked from ships or transloading equipment are difficult to remove from the water surface. Those all factors promote the development of the new and innovative solutions for more efficient water treatment. New solutions of the technical concept of the skimmer are proposed here - among other the theoretically justifiable triangular inlet openings with the system of vertical positionnig relative to the water surface.

Opis:: Helicopter pad located on the ship significantly increase the operational capabilities of military and civilian ships. During the storm, especially side tilts of the ship hinder or even prevent the safe use of the helicopter pad. It is proposed to apply the system placed between the deck of the ship and landing site plate, driven by three independent linear drives located under the deck. The task of the system will be preventing from transferring to Helicopter pad the tilt of the ship around the longitudinal axis and the displacement of the deck along the transverse and vertical axis within the limits of the work area. The mechanism consists of the three movable pillars with the plate on top, which is the movable helicopter pad platform. As the linear actuators, plates moving along a horizontal guide were used, powered by system of steel cables with three independent electric motors. In folded state the mechanism, take up appropriately little space in the deck area. For the assumed extreme amplitudes of the ship motion, minimum dimensions of the mechanism links that meets the requirement to work in one configuration and lack of collisions were determined. Kinematic relationships were created indicate which mechanical quantities should be measured in real time to determine the momentary drives speed. For the adopted assumptions simulation was performed, confirming the predicted behaviour of the system. Based on the dynamics equations of system, drives loads, their power and individual links and joints load were determined.

Opis:: Helipad located on ships greatly increases their ability to perform tactical and logistical abilities. They allow performing reconnaissance from the air, transportation of cargos and people to and from the ship. Landing on a moving ship particularly small size during bad weather is not a safe manoeuvre. Article provides an overview of existing solutions that improve safety during the landing manoeuvre of the helicopter to the ship and describes an innovative mechanism with can stabilize helicopter pad in four degrees of freedom. This solution is characterized in that the landing plate is movable and actuated simultaneously by two support plates and two levers. Plates and levers are driven by separate linear motors that move along the guides connected to the base. The main feature of the mechanism is that when the base is not stable, it can reduce the linear movement of the landing platform in the vertical and transverse direction and angular displacement around an axis perpendicular and parallel to the axis of the ship. A preferred feature of the mechanism is that in folded position it occupies relatively little space. In addition, advantageous attribute of the mechanism is its large working area, enabling the reduction of high amplitude vibration. The article contains a calculation of the kinematics for the proposed structure of the mechanism. It also includes speed drives waveforms, which are the result of simulations for the input parameters of the ship movement.

Opis:: In real systems are non-linear mathematical description. The exact solution can not be determined, and then look for approximate methods. Important is the type of nonlinearity, solutions and error method approximation. Linearization is an essential part of creating a model of the selected process. Ship resistance is a function of power with exponent two and higher. Model motion of the ship must have a solution in terms of maneuverability speed and speed of the sea. The solution must be well reproduce the actual path of the transition and the transition time of the ship. Nonlinear solution method determines the accuracy of the answers. Has presented the revised approach to solve the nonlinear differential equation of parabolic function. Linearization has been made in the selected range, and not where you want it to work and solve the error estimate. Range of solutions selected by external priorities adopted. Before the solution is estimated response error. The error value determines whether the selected interval will apply. If the problem solution is unacceptable, it will increase the accuracy of the result of the narrow scope of the work. The new scope of work should also be reassessed a solution error. This type of approach correlates with fuzzy logic, where we use the value of the Boolean variable with the function of belonging. The combination of classical methods of solving differential equations of the theory of fuzzy sets can bring new benefits. Such a solution must have the function of the accuracy of the answers. The linearization method meets this requirement.

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:: In order to study the characteristics of mixed vessel traffic flow, based on classical head distance model and probability analysis, by studying the combination time head way of different vessel-following sequences, the capacity model of mixed vessels traffic flow was established. Through analyzing two representative types of vessels, research results indicate that the capacity of mixed traffic increase with the traffic flow speed in a certain speed range, but the increasing trend slow down. The closer length and inertial stopping distance of different kind vessels are, the more capacity of mixed traffic increases. And the influence of reaction time on the capacity is related to proportion of different kind vessels.

Opis:: Assessment of students’ achievements in higher education didactics and in maritime studies is considered as a problematic part of study process. Especially it is difficult to use assessment practically in order to improve students’ learning, for formative purposes. The role of formative assessment in the learning educational paradigm is essential. One of main attributes of formative assessment - self-evaluation of students - has been chosen as the object of the research. For the empirical research, a case of full-time studies of Marine Engineering was decided upon. An originally created questionnaire was used for the research. The characteristics of self-evaluation, such as its frequency, forms, and content were analysed with the aim of finding out their influence on the improvement of students’ learning and effectiveness of maritime studies.

Opis:: World marine engineering sector has been developing rather swiftly since recently. Every year the majority of leading shipping companies raise the level of management & maintenance of their vessels. Therefore the requirements to seafarers are increasing constantly. All these circumstances lead to the fact that every next year marine institutions, having limited time for teaching process, meet rising difficulties in seafarer’s proper training. That goes particularly for the special (technical) subjects, which are being taught to future marine engineers and form the level of their proficiency by the time of the graduation.

Opis:: The paper presents search for objective and quantitative method of determination usefulness of various loose sorbents destined for cleaning surfaces polluted with oil. The motivation to take up the topic is that oil pollution emergence in marine areas remains still as the environmental problem. During the ship exploitation there is possibility of appearing of the fuel oil, lubricating oil, hydraulic oil or even transformer oil leaks on the board which might be erased by washing or using sorbent powders and granules or mates. In the case of disposing the washing liquids, the large volume of oil-in-water emulsion is forming which is gathered in a tank and further transported to the vessel cleaning system. In the case when sorbents are applied in an early phase of oil leakage, the vessel cleaning system is less overloaded which reduce the probability of failure. We report analyses of effectiveness of mineral and organic sorbents. The time-period of incepting of defined amount of oil by define amount of sorbent is applied as the sorption effectiveness parameter. Time plots of oil sorption as well as visualizations of this process are presented. Method to characterize the efficiency of sorbents in relation to used lubricating oil is proposed which will stand as the base for further works directed towards elaborating optimal sorbent-set which can be rapidly used for combat spillages and leaks of oils and even other liquid dangerous payloads carried by ships.
