Government vessels are custom-designed to meet various operational needs and may be equipped with specialized tools such as cranes, winches, and diving equipment. Their robust hull structures allow them to carry heavy cargo and equipment. They are commonly used for official tasks such as waterborne engineering construction (e.g., material transport during bridge construction), disaster relief and rescue, and supply transport.
Maintenance and repair of government vessels typically include deck work, engine room work, and underwater work. This includes rust removal and painting of the entire hull, overhaul of the main and auxiliary engines, engine room cleaning, and repair, maintenance, and replacement of certain components.
For example, main engine maintenance requires a comprehensive inspection of critical components such as cylinders, crankshafts, and fuel systems. Through disassembly and cleaning, removal of accumulated dirt, replacement of worn parts, and optimization of the lubrication system, the aim is to ensure the equipment is in good technical condition, extend its service life, reduce the failure rate, and thus meet daily operational requirements.
