How can anodes be installed on a vessel?

Anodes are critical components used to prevent galvanic corrosion on vessels, and their installation is essential for ensuring the longevity and structural integrity of the maritime structure. The correct method of installation involves either bolts or welding, allowing for a secure connection that can withstand the harsh underwater environment.

Using bolts provides the advantage of being a non-permanent solution, which is useful if the anodes need to be replaced or inspected frequently. This method allows for easy attachment and detachment without damaging the vessel's hull. On the other hand, welding offers a permanent fix that is especially suited for anodes that need to endure severe conditions and should remain on the vessel for the entirety of its service life.

The combination of these methods caters to different needs based on the operational requirements and maintenance strategies of the vessel. Therefore, the inclusion of both bolting and welding as valid options for anode installation makes this answer comprehensive and accurate. Other methods, such as using adhesives or magnetic attachment, do not provide the necessary level of durability or reliability required for underwater applications and, thus, are not practical solutions for installing anodes on vessels.
