Blending fuel oil business is a fuel oil supply service mode in which the company blends and processes the fuel oil purchased and put into storage into fuel oil that can be directly used by ships, and then sells it to other refueling service providers and distributors, or sells it to terminal customers such as shipping companies in the form of water refueling operations through the company's special refueling ships. Its business chain includes procurement, transportation, warehousing, blending and processing, sales or water refueling. Blended oil business is a combination of fuel oil value-added service and sales service. Non-blended fuel oil business is a service mode in which the company purchases fuel oil from oil refining enterprises or other suppliers according to the fuel oil market demand information, and transports or organizes transportation to designated places to provide fuel oil to customers. The company's non-blended fuel oil business is mainly a process of supplying fuel oil to fuel oil enterprises that cannot or do not engage in upstream procurement and obtaining service value from them. The future business development direction of the company is to continue to focus on the ship fuel supply service industry, actively develop the mixed fuel business, consolidate the non-mixed fuel oil business, moderately develop other ship supply businesses, and develop the company into a comprehensive ship fuel oil supply service provider with important market influence.
