Overhauling Our Ship's Generator Engine part 1| Seaman Vlog

Summary

The video script details a meticulous 10-day engine overhaul process aboard a ship. It focuses on the number three generator engine, involving the disassembly of hundreds of parts including cylinder covers, pistons, and valves. The narrative emphasizes the importance of careful planning, preparation, and coordination. The team meticulously cleans, replaces worn components, and checks for cracks, concluding with a thorough cleaning and re-lubrication of the engine. This technical procedure is made accessible by the crew's expertise and prior review of engine schematics, promising a continuation of the overhaul journey in subsequent videos.

Takeaways

• 🛠️ The script describes an engine overhaul process, specifically for a ship's number three generator engine.
• 🔧 The overhaul involves dismantling and reassembling hundreds of parts, requiring careful planning and coordination.
• 📅 The process is expected to take about four to five working days to complete.
• 🧰 The cylinder covers and pistons are key components that will be removed, cleaned, and have worn parts replaced.
• 🔄 The piston rings will be replaced, and the piston crowns will be cleaned or carbonized as part of the maintenance.
• 🔍 A crack check will be performed on the piston crowns, connecting rods, bolts, and bearings to ensure safety and reliability.
• 💧 Old lubricating oil will be drained from the crankcase, and the engine will be cleaned and refilled with fresh oil.
• 🔩 The script emphasizes the importance of organizing small parts like nuts and bolts to prevent loss or confusion.
• 📚 Engineers have prepared for the task by reviewing schematics and planning the course of action before starting the overhaul.
• 🛑 Electronic parts, such as thermocouples for exhaust gas, need to be disconnected before proceeding with the engine disassembly.
• 🔧 The hydraulic nuts securing the cylinder covers require special attention due to the high torque needed for their removal and installation.

Q & A

What is the purpose of the overhaul of the number three generator engine?

The purpose of the overhaul is to dismantle, clean, replace worn or damaged components, and ensure the engine operates efficiently and safely.

How long is the estimated time to complete the overhaul of the generator engine?

The estimated time to complete the overhaul is about four to five working days, depending on conditions.

What is the first step in the overhaul process described in the script?

The first step is to loosen all the attachments before pulling out the bigger parts and disconnecting some electronic parts like the thermocouples for the exhaust gas.

Why is careful planning, preparation, and coordination required for the overhaul of the generator engine?

Careful planning, preparation, and coordination are required because the job involves dismantling hundreds of parts, ensuring that none are lost or mixed up with parts from other cylinders.

How are the dismantled parts managed to avoid confusion during the overhaul process?

The dismantled parts for each cylinder are collected in marked containers to ensure that parts are not mixed with those from other cylinders.

What components are removed from the cylinder covers for cleaning and replacement?

The components removed from the cylinder covers include the exhaust and intake valves and the fuel injection valves, which are cleaned and replaced as necessary.

What is done to the piston rings and piston crowns during the overhaul?

The old piston rings are removed, the piston crowns are cleaned or carbonized, and new piston rings are installed. A crack check is also performed on the piston crowns and connecting rod.

What is the procedure for dealing with the old lubricating oil from the crankcase?

The old lubricating oil is drained from the crankcase, the crankcase is cleaned, and then it is refilled with fresh lubricating oil.

How are the cylinder covers secured to the engine frame and how are they loosened?

The cylinder covers are secured to the engine frame by nuts tightened with intense torque. Hydraulic pressure is needed to release or tighten these nuts.

What is the significance of the engine Workshop in the overhaul process?

The engine Workshop is where the cylinder covers are taken for further dismantling of components like intake and exhaust valves and for cleaning the internal chambers.

What is the final step described in the script for the overhaul process?

The final step described is assembling everything back to its original state after all parts have been cleaned, replaced, and checked for cracks.
