In the introduction of ME Engine Control System, I wrote about the ME Engine Control System, under the MPC cards section, I briefly mentioned the LDCL system as part of the Cooling Water Control Unit (CWCU) MPC card. Recently, while troubleshooting to restart the LDCL system on the ship that has been stopped for a…

Jan 26,2022. Rotterdam ကျွန်တော် ဒီစနစ်ကို ခုမှ စ စီးဖူးတာပါ။ တိတိကျကျ ထပ်ပြောရရင် ခု လက်ရှိ သင်္ဘော စီးတော့မှ ကြားဖူး မြင်ဖူးတာပါ။ Main Engine , Propulsion Control System တွေကလည်း ကျွန်တော် မစီးဖူးသေးတဲ့ အမျိုးအစားပါ။ ဒီ သင်္ဘောက တခြား Management ကနေ လက်လွှဲယူတာဖြစ်ပြီး CE တစ်ယောက်ပဲ အရင် Management နဲ့ နှစ်ပတ်အတူတွဲစီးထားပြီး ကျွန်တော်နဲ့ အရင်လိုင်းက EO နဲ့က Handover တစ်နာရီသာသာပဲ ရခဲ့ပါတယ်။ စရောက်ပြီး နှစ်ရက်လောက်ကြာတော့ ME control system ကနေ BWCM Failure ဆိုပြီး Alarm…

ERCS is designed to reduce NOx emissions in exhaust gases according to the IMO Tier III requirements that came into effect after January 2016. There are various technologies for reducing NOx, including EGR (Exhaust Gas Recirculation), Selective Catalytic Reduction (SCR), Water in Methanol (LGIM-W), and Low Pressure Gas Engine (ME-GA). Personally, I have only encountered…

Tacho System In the previous sections, we discussed the MPC, Hydraulic Power Supply (HPS) Unit, and Hydraulic Cylinder Unit. The MPC units handle control and monitoring based on their respective functions, the HPS provides the necessary hydraulic oil pressure for control functions, and the HCUs manage exhaust valve operation, fuel injection, and cylinder lubrication. To…

Cylinder Lubricator The cylinder lubricator is mounted on the distribution block of the hydraulic cylinder unit. It adjusts the lubrication oil flow based on the cylinder lubrication rate sent by the CCU, controlling the on/off cycles and amount of lubrication oil delivered to the cylinder units. The lubricator operates using the system’s hydraulic oil. Hydraulic…

Hydraulic Cylinder Unit (HCU) The Hydraulic Power Supply Unit supplies hydraulic oil to the HCU through double-wall hydraulic pipes. If single-wall pipes are used instead of double-wall pipes, the hydraulic pipes are typically housed within a casing. There are systems with pressures of 300 bar as well as systems with 200 bar. The Hydraulic Cylinder…

Hydraulic System The ME engine’s hydraulic system is an electronically controlled mechanical hydraulic system. The engine control system manages the engine’s fuel oil injection and exhaust valve operation using hydraulic power. The system uses lubricating oil for hydraulic oil and the Hydraulic Power Supply Unit (HPS) provides the necessary hydraulic oil. Hydraulic Power Supply Unit…

Replacing the MPC Card If an alarm goes off on an MPC card, you can read the alarm information from the MOP panel to determine what might be causing the issue. It provides explanations for all possible causes. Some issues and errors can sometimes be resolved by performing a reset. Resetting redundant cards like the…

Auxiliary Control Unit (ACU) There are three ACUs, and they are responsible for managing the Hydraulic Power Supply Pump and the Auxiliary Blower. The ACU operates the start and stop functions of the auxiliary blower based on scavenge air pressure. Additionally, it controls the flow for engine-driven hydraulic pumps and the start/stop functions for electric-driven…

EICU – Engine Interface Control Unit The EICU (Engine Interface Control Unit) is responsible for connecting the Engine Control System with external systems. There are two EICU units installed: EICU A and EICU B. If one unit fails, the other provides redundancy to ensure continued operation. The EICU interfaces with the Engine Remote Control System,…
