Human reliability analysis (HRA) emanating from use of technology for ships navigating within coastal area
The traditional approach to the study of human factors in the maritime field involves the analysis of accidents without considering human factors reliability analysis. The main approach being use to analyze human errors are statistical approach and probability theory approach. Another suitable approach to the study of human factors in the maritime industry is the quasi-experimental field study where variations in performance (for example attention) can be observed as a function of natural variations in performance shaping factors. This paper analyzes result of modeling human error and human reliability emanating from the use of technology on board ship navigation in coastal water area by using qualitative and quantitative tools. Accident reports from marine department are used as empirical material for quantitative analysis. The literature on safety is based on common themes of accidents, the influence of human error resulting from technology usage design, accident report from MAIB and interventions information are use for qualitative assessment. Human reliability assessment involves analysis of accident in waterways, emanating from human-technology factors interface. This paper report an enhancement requirement of the methodological issues with previous research study, monitoring and deduce recommendations for technology modification of the human factors necessary to improve maritime safety performance. The result presented can contribute to rule making, and safety management leading for development of guideline and standards for human reliability risk management for ship navigating within inland and coastal waters
Predictive and reliability based collision risk aversion model for inland waterways: the case frequency estimation for Malaysian Langat River
Collisions of commercial ships cover the largest part of accidents scenario in waterways. Waterways accidents expose vessel owners and operators, as well as the public to risk. They attract possibility of losses such as vessel cargo damage, injuries, loss of life, environmental damage, and obstruction of waterways. Collision risk is a product of the probability of the physical event its occurrence as well as losses of various nature including economic losses. Environmental problem and need for system reliability call for innovative methods and tools to assess and analyze extreme operational, accidental and catastrophic scenarios as well as accounting for the human element, and integrate these into a design environments part of design objectives. This paper discusses modeling of waterways collision risk frequency in waterways. The analysis consider mainly the waterways dimensions and other related variables of risk factors like operator skill, vessel characteristics, traffic characteristics, topographic, environmental difficulty of the transit, and quality of operator's information in transit which are required for decision support related to efficient, reliable and sustainable waterways developments. 5.3 accidents in 10, 000 years is observed for Langat River, this considered acceptable in maritime and offshore industry, but for a channel using less number of expected traffic, it could be considered high. Providing safety facilities like traffic separation, vessel traffic management could restore maximize sustainable use of the channel
Safety and environmental risk and reliability modeling process for sustainable inland water transportation
The vast resources of the world’s oceans need to be fully utilized to benefit human activities in a sustainable manner. The maritime industry has made use of the ocean in a very responsible way, but inland water resources have been much more underutilized and under- maintained, especially for transportation. In an age so dire to find ways to mitigate the challenge of climate change and its associated impacts, recent research has indicated that inland water transportation represents the cleanest mode of transportation. This indicates the potential for an increase in usage of inland waterways for transportation. The use of inland water transportation is forecast to rise because of the potential for short sea shipping, expanding deep-sea operations, and alternative mitigation options for climate change. Coastal water transportation is associated with low probability, high consequence accidents, which makes reliability requirements for the design and operation for safety and environmental protection very necessary. Collision represents the largest percentage of accident risk scenarios among water transportation risk factors. This paper discusses recent work in risk and reliabilitybased design, and safe and efficient vessel operation in coastal waters. This includes systems based approach that covers proactive risk as well as holistic, multiple-criteria assessment of waterways variables required to develop mitigation options and decision support for preventive, protective and control measures for various collision accident scenarios within inland waterways
Study of packing density and temperature on the oil sorption capacity of packed local kapok fiber as bio-oil spill absorbent
Oil spills are global concern due to the environmental impact and consequence of release of affluence. Various commercial products have been development and create to control spills, including the use of fibers as sorbents. This study investigates the use bio-based material of kapok fiber as sorbent materials for oil spills absorption. The study characterized the chemical and morphological properties of kapok fiber, experiment conducted involved FTIR and SEM analysis. Sorption tests with oil were conducted in deonized water thickness of oil and water. Oil sorption capacity by kapok fiber was strongly influenced by packing densities and temperatures. As packing densities and temperatures increased, oil sorption capacity of kapok fiber was reduced proportionally. Kapok shows excellent buoyancy and very high hydrophobicity and oil sorption capacity. The research has shown that kapok fiber can be adapted for sorbent materials for oil spills
Collision aversion model for inland water transportation : cost benefit analysis model
Inland water transportation project is considered today as one of the mitigation option available for humanity t o curb carbon footage. Collision in inland water transportation represents the biggest treat to inland water transportation; its occurrence is very infrequent but has grave consequence that makes its avoidance a very imperative factor. The nature of the threat of collision can be worrisome, as they can lead to loss of life, damage to environment, disruption of operation, injuries, instantaneous and point form release of harmful substance to water, air and soil and long time ecological impact. However, the development of complex system like inland water transportation and collision avoidance system also needs to meet economic sustainability for decision requirement related to collision avoidane. This makes analysing and quantifying occurrence scenarios, consequence of accident very imperative for reliable and sustainable design for exercise of technocrat stewardship of safety and safeguard of environmental. This paper discusses the cost benefit analysis for risk control option required for operational, societal and technological change decision for sustainable inland water transportation system. The paper presents the result of predictive cost for collision aversion aversion for in River Langat waterways development
Utilization of simulation for training enhancement
Engineering system design, operation, and maintenance has been handled for a long time through mathematical and real time models. The advent of computers, multimedia age, and improvement in visualization has further proved the reality of fact that picture speaks more than words; also, research in education and training has proven that visualization has a great effect on improving learning. The complexity of real world situation of engineering education has obvious limitations of instructional presentation and training. Simulation gives result from theoretical representation of complex phenomena when hardware for the task is lacking, or in situations when enough time is not available for explanation. This chapter discusses opportunities brought about by simulator as a tool in the training and certification of the Malaysian Maritime Academy cadets training program. The usefulness of simulators in a continuous education program to amplify and enhance competency-based education and instructional training to meet goals of safety, cleaner ocean, and protection of marine environment are highlighted.

Towards sustainable green ship technology
Man live in two worlds, the biosphere and the techno sphere world over the years, time needs, growth, speed, and knowledge and competition have created demand that necessitated man to build complex institution. Ship design is not left out in this process. Inland water, are under treat from untreated waste that can feed bacteria and algae, which in turn exhaust the oxygen. The ocean cover 70% of the globe, many think that everything that run into it is infinite, the ocean is providing the source of freshening winds and current that are far more vulnerable to polluting activities that have run off into them too many poisons, that the ocean may cease to serve more purpose if care is not taking to prevent pollution. This issue of environment becomes so sensitive in recently and most are linked to infrastructure development work. Most especially in maritime industry polluting activities from oil bilge to ballast pumping that has turned into poison has advert effect on water resources. Some have choked too much estuarine water where there is fish spawn. In a nutshell, the two worlds we live are currently out of balance and in potential conflict. Man is in the middle, and since the treat are mostly water related, ship is in the middle too. Historical records of number of calamity that has resulted to heavy lost and pollution call for environmentally sound ship. This has led to a number of regulations today that will subsequently affect policies change and procedures interaction with the system. The current situation has affected the design of new ships and modification of existing ships. This paper review and discuss green technology emanating from regulations and highlight new system design being driven by marine pollution prevention and, protection and control regulation
