UPAYA PENANGANAN KEBOCORAN TANKTOP PALKA DI MV CAHAYA MUSTIKA LAUT 01

Abstract

This research aims to analyze the causes and handling efforts of tanktop leakage in the cargo hold of MV. Cahaya Mustika Laut 01, a bulk carrier vessel. Tanktop leakage is a serious issue as it can lead to cargo damage, compromise vessel safety, and cause operational delays. This study employs a descriptive qualitative approach with data collection techniques including observation, documentation, and case studies conducted during a one-year sea practice (Prala) undertaken by the author. The findings reveal that the leakage was primarily caused by several factors, including lack of routine maintenance and inspections, the vessel's old age (built in 1996), and heavy impact from unloading equipment (grab bucket), which damaged the already corroded and thinned tanktop plates. Water from the ballast tanks located beneath the tanktop often seeped into the cargo hold, especially after unloading or when the ship was in a fully ballasted condition. Emergency handling involved onboard welding and patching the leaking area using steel plate pieces, while permanent repair was carried out through replating during port stay or docking. Preventive measures included rinsing the hold with fresh water after seawater cleaning, repainting, and supervision during grab operation to minimize damage from impact. Evaluation of the alternative solutions showed that emergency repairs are effective in the short term but cannot withstand repeated pressure or impact, whereas replating offers greater durability despite requiring more time and cost. The study concludes that a disciplined implementation of a Planned Maintenance System (PMS) is essential, and collaboration between ship crew and company management plays a vital role in ensuring vessel seaworthiness and cargo safety.
