Marine insurance protects parties involved in shipping from financial losses. It covers risks like accidents, natural disasters, war, piracy and more. There are various types of marine insurance policies that cover vessels under construction, cargo, and increased ship values. Key parties in marine insurance are the carrier who owns the ship, the charterer who finds carriers, the consignee who receives the shipment, and the consignor who sends it. A bill of lading is a critical document that outlines shipping details and is required for claims of lost, damaged or delayed cargo.
