Question 12 of 30
How purging and seal monitoring is done?
Air or inert gas pipe connected to the line, the two way valve which remains closed is moved to hydraulic oil side and air or inert gas is opened and if there is any leak, it is purged out and the quantity is measured.
Air or inert gas pipe connected to the line, the two way valve is moved to hydraulic oil side and air or inert gas is opened and if there is any leak, it is purged out and the quantity is measured, then the two way valve is moved to the cargo oil side and the air or inert gas is opened and if there is any leak, it is purged out and the quantity is measured

Answer & Explanation
The correct answer is Option B: Air or inert gas pipe connected to the line, the two way valve is moved to hydraulic oil side and air or inert gas is opened and if there is any leak, it is purged out and the quantity is measured, then the two way valve is moved to the cargo oil side and the air or inert gas is opened and if there is any leak, it is purged out and the quantity is measured.
Seal monitoring involves a two-step purge process. First, checking the hydraulic side for oil leakage, then switching the valve to check the cargo side. This ensures both seals are intact and that neither cargo nor hydraulic oil is leaking into the cofferdam.
