5.8.9 Anodes
Corrosion risks of the stainless steel AISI316 buoy hull can be prevented by applying sacrificial
aluminium anodes. These anodes can be fitted to the chain below the buoy (from the second link
from the buoy). In the water an adequate galvanic current path is formed between the anodes
and the hull through the chain and back through the sea water. The layout of the protective
anodes is given in Figure 5.8.6. At least one free link should be left between the clamps and the
buoy. To prevent the nuts from unscrewing Nyloc nuts should be used. Nyloc nuts should be
used only once. The anodes have an estimated life of three years.
Cunifer10 hulls do not require anodes. Because of its short term deployments no anodes
are used on the DWR-G 0.4 m as well.
