Assessment of ship accident risk in the east Surabaya shipping channel using formally safety assessment method

Surabaya East Shipping Channel is part of the busiest shipping lanes west of Surabaya in Indonesia after inflows in Tanjung Priok. With the navigation, channel conditions are long and narrow plus the number of flows in and out of the harbor boats is very vulnerable to accidents resulting in either the stranded sea, ship collision, or other accident types, which would harm the cruise interocular. By looking at the facts above, so it is necessary to conduct a more in-depth study of the accident risk assessment of the shipping channel east of Surabaya. This study aimed to obtain any kind of accident that has a high risk in the port of Surabaya, to know what impact may result from an accident with a high risk and gain steps that can be taken to reduce accidents in Surabaya East Shipping Channel by using Method Formal Safety Assessment (FSA). Of the six types of accidents that occur, there are three accidents with the highest risk of stranded ships, human accidents, collisions with ships dock at the time of sailing ships and dock. The impact of the third accident caused huge material losses. To reduce the risk of all three types of accidents was measured Implied Cost of Averting a Risk (ICAR), the lowest of any risk reduction options. Reduction of risk to do is impose a routine patrol and installation of signs groove ICAR ports have amounted to 234 million, giving a human rescue training vessel which has a value of 112 million ICAR and the latter is tightened harbor area with ICAR 84 million so that unauthorized parties do not enter in the harbor area.

Design Strategy of Emergency Pools at Source Water Protection Areas

The pollution problem arising from the flushing of initial rainwater and wastewater from accidents while transporting dangerous goods to source water protection areas needs to be solved as soon as possible. Therefore, the design of corresponding environmental protection measures should be considered in the engineering design stage. It is necessary to analyze the specific work in combination with engineering examples. Under this background, this paper first briefly expounds the precautions in accident risk analysis and the design of tank capacity and tank body. Finally, by analyzing actual cases, this paper systematically studies the design strategy of emergency pool in source water protection area, hoping to provide new development ideas for the upgrading of relevant work.

A Study on Evaluation System of Risk Assessment at Coastal Activity Areas

Coastal safety accidents are characterized by a high proportion of human negligence and repeated occurrences of accidents caused by the same factors. The Korea Coast Guard prepares and implements various countermeasures to prevent accidents at coastal safety accident sites. However, there is a shortage of safety facilities and safety management personnel according to the limited budget. In addition, the ability to be proactively and proactively respond is low due to the limitations of the coastal safety accident risk forecasting system, which relies on the meteorological warning of the Korea Meteorological Administration. In this study, as part of preparing the foundation for establishing a preemptive and active coastal safety management system that can manage accident-causing factors, predict and evaluate risk, and implement response and mitigation measures after an accident occurs before coastal safety accidents occur. The establishment of a risk assessment system was proposed. The main evaluation factors and indicators for risk assessment were established through the analysis of the status of coastal safety accidents. The risk assessment methodology was applied to 40 major hazardous areas designated and managed by the Korea Coast Guard.

Work accident risk analysis with FMEA (failure mode and effect analysis) method on steel frame bridge project

Risk is the possibility of the occurrence of an event outside of which every activity that is likely to be detrimental is carried out by humans. In the Nangarasong Steel Frame construction project in Flores district, there is uncertainty which will create a risk that can encourage the project and can affect the potential for work accidents. Uncertainty factors can cause risk in an activity that has an impact on decreasing labor productivity, risk of cost, time, and damage to design or technology. To reduce these adverse impacts, a risk management system is needed, which includes analysis, analysis, and monitoring of risks that may occur. Risk management makes an integrated effort to manage the risk of work accidents by using the FMEA (Failure Mode And Effect Analysis) method. All construction projects that may experience accident risks are identified and analyzed for the severity with FMEA, from the results of which the causes and impacts of the work accident risks will be sought. After knowing and the impact of the risk of work accidents, the next action on the risk of work accidents that result.

The influence of weather on fatal accidents in Austrian mountains

Projections of warmer global temperatures in fast approaching time horizons warrant planning strategies for reducing impacts on human morbidity and mortality. This study sought to determine whether increases in temperature and other changes in weather indices impacted rates of fatal accidents occurring in the popular mountainous regions of Austria with the purpose of improving mountain prevention and accident mitigation strategies. The study was based on the merging of 3285 fatal outdoor accidents reported by the Austrian Alpine Safety Board for the period 2006 to 2018 with daily meteorological data from 43 nearby climate stations during the same period. Multivariable logistic regression was used to model the odds of one or more fatal accidents per station and day with weather indices as predictors, controlling for weekend effects bringing more visitors to the mountains. Separate prediction models were performed for summer and winter activities, as well as for specific disciplines. Even after adjustment for concomitant effects impacting mountain fatal accidents, the daily weather indices of temperature, relative humidity, global radiation, cloudiness, snow cover and precipitation were statistically significantly associated with fatal accident risk. In particular, a one-degree Celsius increase in temperature was associated with a 13% increase in odds of a mountain biking accident in the summer and a 8% increase in odds of a mountain suicide in the winter. An increase in global radiation by 1 kWh/m2 was associated with a 11% and 28% increase in fatal accident odds for mountaineering in the summer and touring in the winter, respectively.

Impact of post-stroke cognitive dysfunction on driving ability

The paper aims to present the current views on the impact of post-stroke cognitive deficits on driving ability, and diagnostic assessment practices in this area. Firstly, the neuropsychological consequences of stroke are briefly presented. This part focuses specifically on visuospatial and executive dysfunctions. Among those dysfunctions, unilateral neglect, especially as it is frequently associated with anosognosia, may have the greatest impact on driving ability, leading to an increased accident risk. Then, different approaches to assessing fitness to drive after stroke are presented, including on-road testing, testing with the use of simulator, and clinical assessment focusing on cognition. The role of cognitive assessment in predicting fitness to drive is described in more detail. The Clock Drawing Test is the most appropriate screening measure in this context, as it engages both visuospatial and executive functions. The Trail Making Test is the most popular working memory test in the context of drivers’ assessment, as it requires visual search and psychomotor speed. The Rey Complex Figure Test is another commonly used test. It requires visuospatial and executive functions, and may also serve as a measure of visuospatial memory. Finally, the legal aspects of the assessments are discussed with reference to the practices used in Great Britain, Belgium, Sweden, and Germany. In Poland, there are no detailed standards for post-stroke fitness-to-drive assessment.
