Optimalisasi Sistem Emergency Stop dan Switchboard Alarm Kapal Berdasarkan Analisis Kinerja

Abstract

The ship’s electrical system plays a vital role in supporting the operational reliability of modern merchant vessels. This study aims to evaluate the performance of the emergency stop and alarm switchboard systems on MV HT KUWE and to formulate improvement measures to ensure that protection functions comply with marine electrical safety standards. A descriptive applied method with a technical case study approach was used through inspection and panel function tests conducted from May to June 2025 at the Pertamina Donggi-Matindok Field Port, Luwuk, Central Sulawesi. The observations show that the emergency stop buttons for the bilge pump and CO₂ fan failed to fully cut off the current, while the low insulation alarm and trip system did not respond according to the response time standards stated in the Marine Switchboard Specification Manual (HT KUWE, 2019), IMO, and SOLAS regulations. Identified causes include worn relays, decreased sensor sensitivity, and unscheduled maintenance routines. This research recommends rechecking wiring, replacing aged protection components, recalibrating alarms, and scheduling regular inspections to maintain the fail-safety principle. The findings are expected to serve as a practical reference for the engine crew in planning maintenance procedures and supervising the switchboard protection system to support safe and reliable ship operations.
