Trajectory Guidance Design on Ship with Weather Condition Data Integration

In recent years, the increasing number of ships visited in congested port, resulting ship navigation channels to being experience a higher traffic density, posing the challenging for port operation and marine safety. The congestion in ships approaching navigation channel leads to potentially causing delay, operation inefficiencies, and even rising the risk of marine accident in channels i.e. collision or grounding. This study aims to design a trajectory guidance system to enhance ship safety during navigation, particularly when entering port areas. According to data from the National Transportation Safety Committee (KNKT), there have been several ship accidents with high numbers of fatalities, such as collisions, groundings, and sinkings, especially in shipping areas around ports with limited channel widths, many anchored ships, and restricted maneuvring space. This study employs a numerical simulation methods involving the MMG (Maneuvring Modeling Group) ship dynamics model and integrates real-time weather conditions as primary parameters in ship maneuver (ship speed, heading angle, and rudder angle) and trajectory recommendations. The simulation is conducted by using largest ship and the ship with the highest frequency visit in Tanjung Perak Port navigation channel as case studi while the realtime weather data is also taken into account. The simulation shows that the trajectory guidance poses the ship to be keep on the track of the navigation channel even though it is under weather conditions. This guidance can be used for helping captains to reduce the risk of accidents in narrow shipping lanes, and improves operational safety as well as supports a sustainable and efficient shipping industry.
