Upside down gate valve
On board ship, Mabuk the Cadet Marine Engineer Officer has to face challenging
situations and problems. In this page, we look at one of these problems and we
invite you to give your solution or advice to Mabuk.
Mabuk has been assigned by his 2nd Marine Engineer Officer to service a sea water gate
valve. The valve seems to be jammed in a half open position and cannot be shut properly when needed.
The problem Mabuk has to
solve is how to remove the valve and lower it to the floor safely.
The valve is upside down and it is very heavy. If the chain block is
secured at the valve handle, the valve will swing dangerously - something
Mabuk must not do.
Mabuk has chain blocks, slings, shackles, and the normal workshop tools
and parts available.
What advice will you give Mabuk?
Not sure how the inside of the valve looks like?
