Garbage salvage ships operate in water for a long time, and the water quality in many waters is polluted, so the corrosion of the hull cannot be ignored. Therefore, it is necessary to do a good job in daily maintenance. Once the hull is corroded, it will affect the strength of the ship's steel structure, thus affecting the service life of the ship, greatly reducing the sailing speed, not only affecting the service performance and life of the ship, but also increasing the degree of danger in the voyage, and do a good job of daily maintenance can also reduce the frequency of maintenance, to avoid affecting the daily water cleaning work.
Before starting the salvage vessel, the important parts of the vessel should be checked to ensure that there is no deformation, cracking, leakage, sufficient lubrication of the moving parts, sufficient cooling water in the diesel engine, no noise and normal vibration of the engine. Repair problems immediately to prevent them from worsening. Usually also pay attention to the ship's condition, regular anti-corrosion paint and lubrication of moving parts. Before painting, clean up the hull and remove rust, oxide and oil stains on the surface of the ship. An annual inspection is carried out to replace corroded parts and check the working condition of the diesel engine. If the vessel is to be out of service for a period of time, the vessel should be pulled ashore, inspected for rust damage, painted for maintenance, and sealed.
