Many refineries are located near major seaports because of the following reasons:

1. Crude oil is present in the sea. To extract the crude oil, major refineries are located near the seaport.

2. To avoid the transportation cost of crude oil, many refineries are located near the seaports.

3. Refineries need a huge amount of water for cooling purposes. This requirement is fulfilled by the sea water.
