This so called "after seal oil tank" actual is used for checking whether the #3 sealing ring is leaking or not, if the #3 sealing ring found leakage, the level high alarm device will be activated, then the vent line from the after seal to this tank should be closed.
But it appears it cannot perform this function according to your drawing. Is it the drawing for 57,000 DWT vessels?
You'd better consult your technical department or the oil seal maker, I am sure they will give you a detailed explanation. |
