Many factors have contributed to unsafe cargo operation either during loading or discharging at terminal. Therefore, it is important that the cargo handling operation on tankers is led by the Master or senior officer in-charge. Every crew member involved in the operation must be aware of his or her routine duties and emergency situations.
The necessary precautions and safety measures (in addition to SSSCL) to ensure a lesser risk and incident free operation includes:
1. Alarm system
Check alarm system prior cargo operation; include High Press/Low Press alarm, High Level/Over Fill alarm.
2. Close Cargo Tank Lids
All Cargo tanks lids must be in close position especially while alongside at terminal even empty or loaded.
3. Close Ullage Ports
All ullage ports must be kept close during cargo operations.
4. Close Sighting Ports
All sighting ports must be kept close during cargo operations at all times.
5. Cargo Pump
Check condition and purging of cargo pumps before loading / on passage to discharging port and ensure Emergency Cargo Pump ready to use in case of emergency.
6. Cargo hoses and flange connections
Cargo hoses and flange connections used for chemical / oil handling must be checked thoroughly before use
7. Stop ship Air Con if Required
If the AC system’s intake air is drawing cargo vapors, it should be stopped immediately and the intake ports of the accommodation area should be shut.
8. Keep an eye on mooring ropes
Mooring ropes must be monitored and tended regularly, Temporary stop cargo operations if necessary.
9. Keep personal protective equipment ready
All personal protective equipment must be worn and equipment such as gas detection and SCBA must be kept ready.
