We use two steps: 1. Insert a medical-grade endoscope through the spark plug hole to visually inspect cylinder wall scratches and carbon buildup on the piston top; 2. Extract an engine oil sample to check for large metal debris or emulsification (caused by coolant leakage).

If General Average is triggered, all cargo owners must share the rescue costs. If you purchased marine insurance with a "General Average included" clause under CIF terms through us, the insurance company will cover this high shared cost for you; if you are an uninsured FOB buyer, you will need to pay it yourself.

We will use a megohmmeter (insulation resistance tester) to measure the insulation resistance of the high-voltage bus. If the resistance value is below the national safety standard, it indicates a risk of leakage, and the vehicle will be deemed unqualified.
