In the process of loading and unloading transshipment of the French special line, all or part of the losses caused by one or several pieces of insured cargo falling into the sea. (5) Reasonable salvage expenses paid by the insured for various measures to rescue, prevent or reduce the loss of the dangerous goods within the scope of insurance liability. However, the limit of the insurance company's expenses cannot exceed the insurance amount of the insured goods. The salvage expenses can be borne within an insurance amount limit other than the compensation amount. The French special line (6) has a natural disaster or accident, and it needs to stop at a port in the middle of the port or at the refuge port, resulting in special charges for unloading, loading, storage and transportation of goods. 'Special expenses' are also called 'continuous freight costs'. If the maritime transport is suspended midway, the costs incurred when the ship needs to be replaced to continue the shipment to the destination shall be regarded as the salvage expenses and the insurer shall be responsible for compensation. (7) Sacrifice, apportionment and rescue expenses caused by common general damage. Common average loss includes two parts: common average loss and common average loss. The PICC marine cargo transportation insurance clauses do not clearly stipulate that the insurer should pay compensation for the common average loss of the goods, but in the insurance practice, the insurer still sacrifices the common average loss of the goods first. Pay compensation instead of waiting to complete the joint average adjustment. And the right to demand the sharing of common average loss should be paid to the insurer in France
