APPENDIX 3 HOW TO INSTALL THE RETRACTION TANK FOR WOODEN VESSEL
AP-12
Installation of the tank reinforcement structure
Install the tank reinforcement structure to prevent the retraction tank from coming off and vibrating.
Fix the tank reinforcement structure to the ribs or ship’s superstructure.
Create the tank reinforcement structure considering the structure of the hull. The minimum dimen-
sions of the tank reinforcement structure are shown below. Ensure the reinforcement structure
meets the minimum dimensions or better.
To fasten and assemble the tank reinforcement structure, use the M10 (or more) bolts.
Note:
Make the bolt holes for the tank reinforcement
structure so that the center of any two bolt holes is facing
the ship’s bow.
