This Addendum
to ISO 3913 specifies requirements
for
double bollards used on vessels for inland waterways.
lt lays down the materials and construction
for a range of
nominal sizes 70 to 500 and states the maximum loading for
which the bollards are intended.

After mounting on deck, the bollards shall be coated externally with an anti-corrosive
protective finish.
A Single rope may be used with a load twice that given in the
table.
The bollards shall be made from weldable quality steel having a

twice the appropriate
loading value given in the table. The
