for your additional question:
normally, there are 3 L.O seals ang 1 sea water seal for the LU. shaft seal system, at this condition, it can be only test the sea water seal,
extending knowledge: but there is normally a little L.O inside this seal which we added before lunching for the purpose of protecting of the seal (in the cavity of water seal). |
