    The Coefficient of Performance is a standard criteria for performance analysis of refrigeration cycle. Even if the first law analysis method is widely used to evaluate thermodynamic systems, it deals only with energy conservation. Instead, exergy analysis offers useful indications when the performance improvement is aimed. In this paper it is developed a first and second law analysis. It is studied the influence of different parameters on the Coeficient of Performance and on the exergy efficiency of a two stage vapor compression refrigeration cycle working with ammonia frequently used in fishing industry.

    In order to determine the ship’s vulnerability to magnetic detection all sources generating static and alternative magnetic fields must be considered. Besides ship ferromagnetism and induced eddy currents, major sources of magnetic signatures are corrosion related magnetism - giving both static and variable magnetic fields through various mechanisms, and the stray fiels generated by electric circuits onboard. This paper discusses the last two sources, their characteristics, the various processes of generating magnetic fields and the particular methods of reducing the resulting signatures.

    In this work the double choice for the dead state in exergy calculations is considered. Energy systems for marine and naval applications cover a wide range of possibilities and the exergetic analysis have proven to be a very useful tool at the previous design stages. Exergetic efficiency calculations of power generating systems allocated on board require a dead state definition as well as the knowledge of ambient conditions at any location defined by latitude and longitude. Temperature, pressure and relative humidity values at sea level all over the world have been estimated by using EdGMC software. Total exergy of ambient air and a methanol/water liquid mixture has been calculated at every latitude and longitude by using a unique dead state and a local dead state. The results obtained with both dead states are compared.

    At the beginning of the 20th Century, as humanity entered the age of industrialism there was not a soul asking the question what the effects on the environment would be. However, the negative impacts that have gripped the entire planet are now undisputable, although at that time, because the human activity was negligible so was its impact. This paper focuses on how maritime transport acts as a pollution source, and what can be done to reduce the quantities of pollutants, looking both at the existing technologies and at latest research programs. The Green Ship idea refers to ideal ships that are environment friendly. We will detail this looking from two points of view: The first one is the Green Ship being a vessel that uses alternative means of propulsion, where the internal combustion engine is replaced with electrical engines that use sun charged voltaic batteries, or rotary sails, or sails that are raised to high altitudes. The second idea refers to what can be practically done on board ships to reduce pollution. This includes, improving the quality of fuel or lowering its sulphur content, improving the construction process or methods for ship hulls or engines.

    The surface hardening by induction heating has many advantages over other methods of conventional thermal processing. It is known that this method is applied to achieve high hardness in the surface layer maintaining a resilient core. The implementation of the required thermal cycle depends both on the characteristics of the material undergoing processing and of the parameters of the system of induction impact. Some difficulties arise in high-frequency hardening of internal cylindrical surfaces of ferromagnetic joints with relatively small diameters, as there is a pronounced the Ring effect, leading to displacement of the eddy currents in the detail and to reduce the efficiency, and hence the quality of the products. The purpose of this work is to study the technological aspects of the induction hardening of internal rotary surfaces.

    Marine corrosion and striking balance for efficient inhibitor remain a big challenge for maintainace of marine system and stucture. Bio material is reliable inhibitor for marine corrosion maintenance. Aluminum and its alloys exhibit corrosion resistance in many environments. This feature made them important materials with wide ranges of industrial and marine applications. Thus, with corrosion resistance, it still need some protection when introduced to the marine environment. It is because the marine environment is a very corrosive environment due to the presences of Natrium Chloride. Several methods have being introduced to overcome this problem. Among the methods introduced, the usages of corrosion inhibitor are very popular. This paper studies the use of vanillin as an inhibitor for aluminium alloy AA7619 in marine environment. This study determine the suitability and the inhibition efficiency of vanillin on aluminium AA7619 corrosion. There are two types of solution prepared which is seawater and seawater with vanillin added. The concentration of vanillin used was 20 mg/litre. These solutions were used as corrosion medium for the aluminium AA7619 immersion test. The immersion period was 42 days and the specimens characterization test were performed every seven days. The corrosion rate of the aluminium alloy and the corrosion inhibition of vanillin were determined by using weight loss method, potentiodynamic polarization scan and electrochemical impedance spectroscopy (EIS). The results shows that the presence of vanillin retards the rate of dissolution and thus the corrosion rate was decreased.

    Accident consequences resulting from collision remain a big threat to coastal water transportation operation. The nature of the threat can be worrisome; the danger may involve instantaneous and point form release of harmful substance to water, air and water causing a long time ecological impact. That may lead to the loss of life, damage to the environment, disruption of operation, injuries. This makes scientific risk based design that analyse all components of risk including the quantification for consequences of accident very imperative for reliable design and exercise of technocrat stewardship of safety and safeguard of environmental. System risk has been widely assessed using traditional environmental impact assessment, a checklist based approach that ends up bypassing a lot of uncertainty that comes with complex and dynamic systems. Novel analysis of frequency, consequence, subsystem and uncertainty components of system risk using g hybrid of deterministic, probabilistic and stochastic process represent a modest best practice for sustainable system design. This paper discusses the result from analysis of damage components for collision accident towards generic risk mitigation option and decision support required for operational, societal and technological change for sustainable inland water transportation system for Langat River. The risk on Langat River determines by consideration the actual situation of the channel and suppressing the system parameters under pressure and determines the reliability of the trend generated from the model. The present risk consider on Langat is found to be low in the absence with ongoing improvement plan. Accident frequency is of 3.8E-5 and consequence energy of 31MJ, resulting to length of collapse of 9.3m. The damage estimation is further simulated for all channel variable parameters to determine the generic risk and reliability condition that can be used for traffic situation limit definition for safety and environmental preventive risk avoidance within inland waterways.

    Dredging work and placement leads to changes to the environment. Environmental impact assessment has been employed to address these changes. Risk assessment which rarely covers large part of uncertainty associated with dredging work is captured in EIA. EIA focus on fixed and inflexible standards which have led to post dredging failures. This makes it necessary to do critical and dependability scientific risk analysis that quantitatively determine whether the changes are serious or irreversible. This paper discuss the new internationally recognized philosophy of risk analysis or formal and system risk based design that provide opportunity to focus on real concern of the dredging project. The paper will discuss case study of failed project based on conventional EIA and best practice performance of systemic risk base design approach.

    Industrialization has brought forth comforts and catastrophes. In the regular scheme of technological developments, the worst malady faced by man is the defiling of the environment. Shipping, being a heavily regulated industry, has contributed less in comparison to other land based polluters. But the enormity of an oil spill and the post-spill clean-ups are reasons enough for countries to tighten the pollution laws and today, any action violating these laws is seen as a crime. Ships are being detained, penalized for pollution violations. Environmental concerns and criminalizing incidents have become issues of concern. While considering these view points, a worthwhile approach would be to look at the seafarer training. Assessment of the competency of the shipboard officer is largely carried out by examinations and onboard assessments. This could be extended to other means such as research surveys. The Paper projects inputs from a study undertaken to assess the level of training and awareness in pollution matters amongst shipboard officers. The representative sample for the study was largely drawn from the Malaysian seafaring officers and also the Indian officers for better representation of the worldwide officers. Curriculum exposure to MARPOL, intensity and level of ship operational issues such as bypassing the separators and falsification of record books were analyzed in the study. Insight was obtained in difficulties experienced while following MARPOL practices. Typical training syllabi were compared to suggested Lesson Plans, survey results were analyzed by statistical methods to verify framed hypotheses on pollution violations and human factors such as experience, attitude and fatigue also, but the Paper focuses on the issue of training. Training appears to be adequate; ANOVA tests show no difference in levels of awareness. Attitude towards pollution prevention practices appear to diminish with increased training, though not significantly. From another Chi-square test, it was seen that involvement in pollution violation incidents does not relate to the quantity of training imparted. Further tests indicate attitude and fatigue as influencing causal factors for shipboard oil pollution violations. Training may be nominally improved with simulator packages and by upgrading trainers’ knowledge. Environmental protection can be treated as a separate subject in the curriculum.

    The employability of seafarers is directly linked to their competency level. Perhaps, this is the main reason why crew members from certain countries enjoy preference in the employment market. Therefore, the sea career prospects of Malaysian seafarers should be viewed from their competency which strongly related to the kind of training offered by Marine Education Training (MET) institutions. In this paper, the developments of maritime industry in the last 10-15 years reviewed the limitations of the STCW 95 training standards in achieving the knowledge demands of high technological equipment on board new merchant ships is reviewed. The authors identified essential training for Malaysian seafarers. Malaysian Maritime Academy (ALAM) has taken important initiatives of enriching MET curriculum work done, beyond the minimum stipulation of the STCW 95, and benchmarking with leading world class MET institutions is reported. The DNV Sea-Skill audit and certification is an example of the commitment by ALAM which offer a program for competence beyond compliance. The paper also reviewed discusses the importance of University Malaysia Terengganu (UMT) degree program maritime Technology as support to need for more theoretical knowledge required to compliment STCW.

    A floating wind turbine is an offshore wind turbine mounted on a floating structure that allows the turbine to generate electricity in water depths where bottom-mounted towers are not feasible. The wind can be stronger and steadier over water due to the absence of topographic features that may disrupt wind flow. The electricity generated is sent to shore through undersea cables. The concept for large-scale offshore floating wind turbines was introduced by Professor William E. Heronemus at the University of Massachusetts in 1972. It was not until the mid 1990’s, after the commercial wind industry was well established, that the topic was taken up again by the mainstream research community. As of 2003, existing offshore fixed-bottom wind turbine technology deployments had been limited to water depths of 30 meters in the case of monopoles, and 50 m in the case of jacket/tripod type. Worldwide deepwater wind resources are extremely abundant in subsea areas with depths up to 600 meters, which are thought to best facilitate transmission of the generated electric power to shore communities.

    Rising oil prices, increasing competition in the maritime industry, climate change and pollution are significantly more prevalent among the causes of the search of alternative energy other than the use of fuel. One of the forms of energy that is suitable to use by boats is the wind energy. Kite has been used by several types of ships in experimental stage to complement the main engine to move the ship. This study is describe a few subtopics on wind energy potential in Malaysia development of wind assisted ship devices and the major discussion on the feasibility of incorporating kite technology to move the boat in Malaysia (Terengganu) waters that have been selected to save the consumption of fuel. The amount of power saving was calculated using the formulae from the previous research. Then, economic assessment was carried out based on amount of power saving. Using kite propulsion technology, fuel consumption was reduced around 30% per year thus resulting in lower and operation costs on the particular routes. The results of the economic assessment indicate that, annual average cost for boat with kite sail is lesser than annual average cost for boat without kite sail. It is expected that the capital investment in the new device will be recovered within 9 years

    The paper is intended to show the importance of linguistic analysis in the process of creating teaching/learning materials for students who begin their academic career at Maritime University. The strategy of Maritime English teaching in the countries where English is not the native language is of upper priority for ESP (English for Specific Purposes) departments. Marine Engineering terminological system causes certain difficulties for students in the process of acquiring professional skills through abundant reading and writing. Therefore, the contents, structure, amount of Marine Engineering word stock should be properly studied, described, arranged and presented in a dictionary pursuing practical goals. The format of the dictionary is the main concern for a researcher. The textual study based on such linguistic parameters as origin of terms, their frequency, derivation, combinability, structural peculiarities, etc, helps to develop authentic teaching/learning materials which facilitate the process of acquisition and application of special terms in real-life communication.
