I am part of the crew of the MV Schamonchi, a former ferry currently docked in Bushwick, Brooklyn. We have recently discovered that the flange gaskets on both of the smokestacks (coming off of Rolls Royce V12s) have been blown out, and are trying to figure out the proper procedure to install new ones. We see two possible ways to go:
- Prop the top part of the smokestack on blocks (the leak is in the middle and the section has two flanges about 16 inches apart, allowing us to remove the middle piece), redo the gaskets, and slide it back in,
- Install some anchor points, and use some chain hoists to lift the stack off the flange.
Stack and flange diameters are about 11" and 16" respectively
Follow this link for some stats on the boat and a couple of pictures:
We are pretty new to this. Any input and advice as to the proper procedure would be greatly appreciated!
