OPTIMALISASI SISTEM PELUMASAN PADADIESEL ENGINE GENERATOR PADA KAPAL MV.AVENIR ACHIEVEMENT

Abstract

Muhammad Raja Navazsiva. 2025. " Optimization of Dual Fuel Diesel Engine Generator on MV.AVENIR ACHIEVEMENT Ship” This study aims to optimize the performance of the Dual Fuel Diesel Engine (DFDE) generator system aboard the MV. Avenir Achievement. DFDE technology enables engine operation using both gas and diesel fuels, offering high efficiency and lower emissions. However, two main operational issues were identified: an ineffective lubrication oil (LO) cooling system and high exhaust gas temperature. Using a qualitative approach with observation, interviews, and documentation conducted over a 12-month sea practice, it was found that overheating was caused by underperforming freshwater cooling pumps and clogged cooling lines. Meanwhile, incomplete combustion was triggered by dirty air filters, suboptimal turbocharger function, and unbalanced generator load distribution. Analysis using the Fishbone Diagram method helped systematically identify root causes. Recommended solutions include regular maintenance of pumps and filters, cleaning of freshwater lines, and the installation of real-time temperature sensors. The findings are expected to serve as a practical reference for improving DFDE system maintenance and management, ensuring more efficient, reliable, and environmentally friendly ship operations.
