    Opis:
    This paper presents a computational model which describes motion of an object of six degrees of freedom (DoF), intended for simulation of spatial motion of one- or two- rope-sling lifeboat or rescue boat during its launching from ship in rough sea. This is a complex model which accounts for sea conditions as well as elasticity and damping properties of davit’s elements and mechanisms, rope and boat hull. Also, are presented results of example calculations for an assumed set of technical parameters of davit and boat as well as sea conditions.

    Opis:
    Year-after-year increasing number and size of sea-going passenger ships make it necessary to search for novel methods of evacuation of passengers from such large objects or to improve those which have been applied so far. This paper presents a concept of one of the original methods, in which, a.o., chain lifts have been applied to hold up life boats during voyage as well as to launch them in case of evacuation. Technical assumptions and requirements as well as schematic diagram of the hydraulic drive and control system of the lift, is presented.

    Opis:
    Presented are regulations concerning the operation of passenger ships (with particular emphasis on Polish ferries) designed to increase maritime safety the SOLAS Convention, established in 1974 and codified in 2002, codifies these regulations, and the International Maritime Organization mandates additional regulations, created in response to a rapidly increasing number of maritime disasters. The analyses described herein were based on restrictions established for the “Jan Śniadecki” and “Mikołaj Kopernik” ferries. Safety of ro-ro units, which also typically have a significant number of people on board, was also analyzed. Also included in the study were ship operational- limitation characteristics with respect to structure, unsinkability, and stability of machinery and electrical equipment, fire protection, operational requirements, and rescue measures and devices, along with their purpuroses. Safety management consists of taking appropriate actions to prevent or minimize the effects of an accident or a disaster and is assessed on the basis of calculations and experience gleaned from analogous cases. Safety management can proceed if a problem has been thoroughly assessed. The potential risk of negative consequences with respect to the safety of the transport process as a whole must be considered, and the safety of the whole must not be risked for that of a particular part of it. A safety management decision can be made when its necessity is not in doubt. A problem is assumed to have only one solution. The effectiveness of the previously used method should be carefully assessed before proceeding to the next method. Security management is not easy and requires much professional knowledge and experience.

    Opis:
    John B. Lacson Foundation Maritime University (Arevalo), Inc. is mandated to offer aquatic-sports courses such as paddling, rowing, sailing, and swimming to equip students with needed skills essential for survival in case of emergencies. Since, there is a dearth of instructional materials in Physical Education 2 (Advanced Swimming and Life-saving Techniques), the JBLFMU-Arevalo was given a research grant by the CHED (Commission on Higher Education) known as DARE TO (Discovery Applied Research and Extension Trans/Inter-Disciplinary Opportunities) to address the problem. This DARE TO grant aimed to develop instructional materials in PE 2 that will enhance the swimming performance and life-saving techniques of students. That is why the researchers would like to test for the effectiveness of this instructional material in the form of modules over the traditional approach which is lecture in improving the students’ swimming performance and life-saving techniques in terms of their knowledge and skills. This non-equivalent control group under quasi-experimental study was utilized among the BSMT (Bachelor of Science in Marine Transportation) students. A pretest was used to determine swimming performance of the experimental and control groups. An intervention through the use of instructional materials was employed in the experimental group for the whole semester (five months) while the control group was exposed to lecture as a traditional method of instruction. After a semester, the posttest was administered. The statistical tools used were mean, standard deviation, Mann-Whitney test, and Wilcoxon-signed ranks test. The findings of the study revealed that the instructional material is effective in enhancing the swimming performance and life-saving techniques of students both in the aspects of knowledge and skills. Both the experimental and control groups were “Fair” in their knowledge pretest scores but during the posttest, the experimental group was “Good” and the control group was “Fair”. On the other hand, both the experimental and control groups were “Fair” in their skills’ pretest scores but during their posttest, the control group was “Good” while the experimental group was “Excellent”. The experimental group who used the module showed significantly better performance during the posttest both for knowledge and skills compared to the control group who did not use the module (lecture only). The study further showed significant differences in the mean gains between the experimental and control groups after the conduct of pretest and posttest in favor of the experimental group. It can be gleaned from the results that the module can enhance the knowledge and skills in swimming performance and life-saving techniques of the experimental group. It is highly recommended that this module be utilized among maritime schools offering swimming and life-saving courses.

    Opis:
    This paper presents a continuation of the projects [5, 6] dealing with the novel concepts of evacuating people from large passenger ships. A novel integrated drive and control system for chain lift with lifeboats fastened on it as well as for stern port- ramp, is presented. Additional novel elements is the application of the stern port - ramp fitted with a buoyancy element, and its increased capability of automatic adjusting its operational deflection in the case of a large forward trim of ship. It increases safety and comfort of evacuation in the difficult conditions, but to obtain it a more complex drive and control system has been required to be designed.

    Opis:
    Today, a significant number of quite advanced technology applications support safety at sea. To the dismay of the maritime industry, the manifestation of passengers during an evacuation scenario/case has not followed a similar path of improvement, when compared to the counterpart Life Saving Appliances (LSA) Code. Embarkation and muster proceedings are still following the similar approaches that were established during the early 1900s. There have been relatively few advances in these procedures; most often, they include manually checking-in the passengers on electronic systems, along with “on the spot” completion of check-off lists and passenger counts, allowing for an influx of potential error by the concerned personnel. Furthermore, the rely and transmission of the manifest to a Maritime Rescue Coordination Centre (MRCC) is often associated with a considerable amount of time, or even involving secondary passenger counts, after the disembarkation event has been concluded. It is understandable that a vessel with limited people on-board (tankers, bulk carriers, container vessels, etc.) can effectively be abandoned in a matter of minutes, but what happens with vessels carrying a large number of passengers and more specifically those heavily engaged with cruising activities? This paper examines the creation of an electronic manifestation system that will be able to automatically record the passengers during lifeboat embarkation. This proposed system will employ the use of Near-Field Communication (NFC) and/or (Radio-frequency identification) RFID bracelets, that are already utilized within the cruise industry. It will record relevant passenger and crew data, upon their boarding on the designated lifeboat, through readers installed on the parallel sides of the entryway. The data will be displayed in electronic tablet devices to the lifeboat leaders, as well as to the Master of the vessel in real-time. This will allow for an accurate representation of the evacuation process in any given moment. Furthermore, a complete “snapshot” of that information can also be directly transmitted to the MRCC via an automated message and without any further human intervention, or even stored locally aboard the lifeboats used for the evacuation and the ship’s Vessel Data Recorder (VDR).
