Abstract

The S-Band radar is a primary navigational instrument used onboard ships to detect surrounding objects and support decision-making, particularly in low-visibility conditions. In practice, radar performance may degrade due to sensor failures or integration issues within the ship’s Integrated Bridge System (IBS). This study aims to analyze the factors causing performance disruption of the S-Band radar on MV Golden Rose while navigating in Bunati Waters, as well as to evaluate the compliance of the radar’s Planned Maintenance System (PMS) with the maintenance schedule.The findings reveal that the radar malfunction was triggered by simultaneous loss of essential sensor inputs—such as heading (HDG), speed through water (STW), Automatic Identification System (AIS), and unstable GPS data. Initial troubleshooting identified moisture on RS-422 connectors, possible corrosion, and component degradation due to aging. The study also found discrepancies between scheduled and actual maintenance activities, notably delayed antenna inspections.Overall, the degradation of radar performance is more dominantly caused by internal system deterioration, as indicated by corrosion and oxidation on navigation sensor connectors, instability in the power supply, and the gradual loss of sensor inputs as recorded in the radar operation logs caused by insufficient preventive maintenance and deteriorating hardware integrity. These findings highlight the need to strengthen radar maintenance procedures and improve sensor integration management to ensure safer navigation.

Abstract

This study aims to identify the efforts that can be undertaken to prevent work accidents onboard merchant vessels, using MV. SIAM as a case study. A qualitative case-study approach was applied, with primary data collected through direct observation, in-depth interviews, and documentation during the author's sea practice (PRALA) from 8 April 2024 to 22 April 2025 in the Red Sea and Arabian Sea. Data were analysed descriptively through data reduction, data display, and conclusion drawing/verification. The findings show that the work accident experienced by a Boatswain, caused by a rebounding cutting disc while operating a portable grinder, resulted from a combination of individual negligence in pre-use equipment inspection, non-compliant use of personal protective equipment, unfit equipment condition, and weak on-site supervision. Continuous safety training, routine equipment inspection, strict enforcement of personal protective equipment use, and a transparent incident-reporting system are required to address these issues. Strengthening a consistent safety culture is expected to minimise the risk of work accidents and to sustain maritime safety onboard MV. SIAM.
