To prevent oxygen ingress, there are two basic methods; hot lay-up and cold lay-up. Hot lay-up is preferred when practical because it reduces the thermal stresses on the system metallurgy but, of course, requires a source of heat. The idea is to keep the system under positive pressure so that oxygen is unable to enter the boiler.
