COLLISION DAMAGE CONSEQUENCE RISK RELIABILITY FOR LANGAT RIVER (MALAYSIA) SUSTAINABLE INLAND WATER TRANSPORTATION

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.
