No Perfunctory Regular Overhaul: Sorting Out Core Technical Control Details

Ship regular overhaul needs to be arranged in an integrated manner in combination with the statutory inspection cycle, covering in-depth investigation of all core systems of the whole ship. During the main engine overhaul, complete the component disassembly and inspection, wear measurement and clearance adjustment in accordance with the specifications, file the loss data of key components such as pistons, cylinders and bearings one by one, to ensure that all parameters meet the equipment operation limit requirements. For electrical system overhaul, focus on checking the insulation performance of the switchboard, the sensitivity of protection devices and the reliability of the emergency power supply system, and timely deal with aging lines and rusted terminals to ensure the stable power supply of the whole ship. After the overhaul is completed, carry out mooring test and sea trial according to the regulations, continuously monitor the equipment operation status under the corresponding load, sort out the complete test data report, confirm that the performance of all systems is restored to the original design standard, and meet the safety conditions for subsequent operations.
