DELAY IN RESPONSE LEADS TO DAMAGE TO PUMP CASING
23rd Feb. 04
On my ship the air compressor cooling water flow alarm was activated, and the compressor stopped.
When checked the cooling water pump casing was found cracked (hairline only).
After taking safety precautions the casing was removed and replaced by spare cooling water p/p casing, Air comp tried out found running satisfactory.
Cracking attributed to delay in stopping pump after sounding of alarm.
