WAN NIK W.B.; SULAIMAN O.O.; PRAWOTO Y.; AHMAD M.F.; ROSLIZA R.10/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesMarine 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.Read More -
COLLISION DAMAGE CONSEQUENCE RISK RELIABILITY FOR LANGAT RIVER (MALAYSIA) SUSTAINABLE INLAND WATER TRANSPORTATION
SULAIMAN O.O; SAHARUDDINA.H; SAMAN AB.; WAN NIK W.B10/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesAccident 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.Read More -
ENVIRONMENTAL RISK AND RELIABILITY FOR SUSTAINABLE DREDGING
SULAIMAN O.O; SAHARUDDINA.H; WAN NIK W.B; SAMAN A.B.10/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesDredging 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.Read More -
EFFECT OF TRAINING ON SHIPBOARD OIL POLLUTION VIOLATIONS
SAHARUDDINA. H; R. BALAJI; SULAIMAN O.10/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesIndustrialization 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.Read More -

SAHARUDDINA.H.; SULAIMAN O.O; SAMAN A.B.; WAN NIK W.B.10/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesThe 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.Read More -

FLOATING OFFSHORE WIND FARMS: THE SEED OF ARTIFICIAL
Pardo Miguel LAMAS ; Rodrigo Pérez FERNÁNDEZ10/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesA 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.Read More -

Nadiya DEMYDENKO10/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesThe 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.Read More -

IMPROVEMENT OF THE CONTACT RIVETS DURABILITY OF SHIPS’ ELECTRICAL APPARATUS BY USE OF MULTILAYER TITANIUM NITRIDE COATINGS
Bohos APRAHAMIAN; Alexander GAYDARDZIEV10/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesRequirements to the materials for electrical contacts are increased due to high loads and high operating temperatures. Often conventional single-layer coatings of electrical contacts can not meet these requirements. Using multilayer coatings allows the requirements to the contacts to be complied and also to control structure (internal stresses and elastic behavior of the material), and therefore to control the properties of coatings. Particularly hard, wearing and corrosion resistant are coatings of titanium nitride TiN type. By simultaneous and coherent operation of two types of plasmatrons – Electric Arc Plasmatron (ARC) and magnetron (MS - Magnetron Sputtering) we have experimented the following three types of coatings on electrical contacts of contactor K6E: Monolayer coating of titanium Ti; Double layer coating of titanium - titanium nitride, Ti/TiN; Triple layer coating of titanium-titanium nitride-titanium Ti/TiN/Ti. Coating is done in combination of the following factors: thickness of the coating and composition of the gas environment in the vacuum chamber, in which they are implemented and tested 10 different modes of coating. It has been observed that modification of the interface by the formation of the surface layer can lead to increase of the electrical contact durabilityRead More -

ROSLIZA4/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesSeawater is inherently chemically aggressive. Marine structural material used in seawater handling is subjected to varying degree of corrosion depending upon nature and operational conditions. A study was undertaken to investigate the effect of seawater on aluminium corrosion. Natural honey has been evaluated as a corrosion inhibitor for aluminium alloy in seawater by electrochemical measurement and surface morphology examination. The effect of natural honey on the charge transfer resistant is measured at various concentrations. EIS studies showed that there was significant increase in overall resistant after addition of natural honey. The inhibition efficiency increases with increase in inhibitor concentration. The nature of adsorption of natural honey on the metal surface has also been examination. The analysis of SEM and EDS confirmed formation of precipitates of natural honey on the metal surface, which reduced the overall corrosion reaction.Read More -

IMPROVEMENT OF THE ENERGY EFFICIENCY OF VESSELS AS A MEASURE FOR THE REDUCTION OF GREENHOUSES GASES EMISSION FROM SEA SHIPPING
Mihaela SIN; MARTÍNEZ DE OSES F.Xavier4/1/2011Marine sciences and engineering; Renewable energies; Marine renewable energies and Sustenability; Advanced technologies for MET; Climate changesAs all we know, pollution is a serious actual problem that affects our society. Maritime transport is responsible of part of that pollution and with this purpose; measure to be taken in the logistical and maritime transport field is to reduce ships emissions. Air pollution is not the only problem, but greenhouse gas emissions too, mainly in the case of maritime transport pollutants as NOx and SOx gasses. This article tries to do a quick view on the last measures took by the International Maritime Organization (IMO) in order to reduce greenhouse gas emissions of shipping. An energy efficiency index for ships was created by the Marine Environment Protection Committee (MEPC) to improve their energy efficiency and then reduce fuel consumption. This index was developed in voluntary interim guidelines established in last sessions of the MEPC among 2009 and 2010, and can be applied to both new designs and ships in operation. Nowadays is just a voluntary measure that whatever ship-owner could take and verify, but until its approval there is for the moment no sanction if the results are not the expected ones by the guidelines. A description of the above mentioned guidelines will be exposed.Read More -
