ANALISIS KERUSAKAN MARINE GROWTH PREVENTION SYSTEM (MGPS) UNTUK KELANCARAN SISTEM PENDINGIN DI KONDENSOR UTAMA PADA SS.TRIPUTRA

Abstract

Nov Ginting, Patar. 2025 “DAMAGE ANALYSIS OF MARINE GROWTH PREVENTION SYSTEM (MGPS) FOR SMOOTH COOLING SYSTEM OPERATION IN MAIN CONDENSOR ON SS.TRIPUTRA” Marine Growth Prevention System (MGPS) is an important system on ships to prevent the growth of marine biota and corrosion in the seawater cooling system. This research was conducted on the SS. Triputra ship after a disturbance was found in the MGPS system that affected the smooth cooling in the main condenser. The main problems identified included damage to the PCB Card due to high temperatures, accumulation of sodium hypochlorite crystals on the anode and cathode, and leakage in the Marine Growth Prevention System output pipe due to scale and corrosion. The research method used was descriptive qualitative with the Root Cause Analysis (RCA) approach, through direct observation, interviews with the Machinist, and documentation and literature studies. The results showed that the main factors of damage came from the lack of routine maintenance according to the Plan Maintenance Schedule (PMS), low material quality, and irregularity in the supply of electric current. As a result, the electrolysis process did not run optimally, inhibiting the production of sodium hypochlorite, and triggering the growth of marine organisms and reducing condenser efficiency. This study concluded that periodic maintenance, cleaning the anodecathode, checking the electrical system, and crew training are very important to maintain the performance of the Marine Growth Prevention System. Recommendations for improvement include increasing the discipline of implementing the Plan Maintenance System (PMS) and using standard materials to improve the reliability of the cooling system on board the ship.
