NAVIGATIONAL SAFETY OF INLAND WATERWAY TRANSPORT SYSTEM (IWTS) IN SARAWAK: RAJANG RIVER

Abstract

Inland water transportation is regarded as one of the most effective ways for humanity to reduce its carbon footprint. The Sarawak Inland Water Transport System (IWTS) has become an essential tool for its residents due to its geographical location. They have access to basic facilities along the rivers’ tributaries through their water transportation. Currently, undeveloped IWTS in the Rajang River has become a navigation safety issue depending on the type of vessel, with insufficient navigational aid installed in certain areas. The nature of the inadequacy of navigation safety can be daunting as it can lead to loss of life, damage to the environment, disruption of operations, injuries, and a long-term environmental impact, often causing severe consequences. This study assessed navigational safety on the Rajang River and recommended appropriate improvements based on the most recent specification requirements of the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) (IALA, 2009). The 3D area simulation of navigation marks will be developed using Sketch-Up Software based on satellite image data. The data was then analysed using Risk Assessment (Fuzzy-AHP technique) to propose the most appropriate aids for navigation and their placement. The proposal and design of aids in navigation for Tanjung Rajang River will increase safety and security for the shipping industry, increase turnaround time, and help maintain a zeroaccident rate.
