PRESSURE TEST OF THE CARGO PUMP’S COFFERDAM
CARGO LEAKAGE
If a cargo leakage is detected the complete cargo pump’s cofferdam has to be pressure tested to identify the leak. We have learned from Framo on board training that the crew on some ships start to automatically change the pump’s cargo seal as soon as there is a cargo leakage - although the leak may be somewhere else.
This is waste of time and money. So always identify where you have a leak first!
