A pressure control system and a method for a storage tank for a ship are disclosed. The pressure control system of the storage tank for a ship of the present invention includes: a storage tank provided on a ship and storing liquefied gas; a buffer tank for receiving and storing boil-off gas generated from the storage tank; and a pressure compensation line connected from the buffer tank to the storage tank. When the pressure of the storage tank needs to be reduced, the boil-off gas is discharged from the storage tank to the buffer tank, and the pressure of the storage tank is adjusted by injecting the boil-off gas from the buffer tank into the storage tank when the pressure of the storage tank needs to be increased.
