A high pressure swivel system provides fluid communication on a turret-moored vessel between a swivel core member being in fixed rotational alignment with a seabed mooring system and a swivel revolving member being in fixed rotational alignment with the hull of the vessel. The revolving member has upper and lower radially extending surfaces. On each of the radially extending surfaces are a series of radially spaced apart pressure seals. Hydraulic barrier fluid pressure is regulated in each of the volumes formed between the pressure seals. The pressures in the volumes are regulated such that a process fluid pressure higher than could be tolerated by any one individual pressure seal is safely accommodated by sharing the high process fluid pressure between or among two or more of the radially spaced apart pressure seals.
