Twin-leg mooring bollard in seven sizes from 12 in (305 mm) to 24 in (610 mm), with safe working loads from 3.15 to 12 tonnes and matched to mooring wire from 12 to 51.5 ton breaking strain.
Before you specify a load
The rating below is the bollard's. It is not a substitute for a mooring analysis. Nominal bollard loads from BS 6349-1-2, PIANC 153B and EAU 2020 can be used directly for vessels up to about 20,000 tonnes loaded displacement; above that they are preliminary-design figures only. We supply the fitting — the mooring study and the holding-down design are your engineer's.

All dimensions in millimetres.
Page 201 of the catalogue was printed in inches; the figures above are converted to millimetres. Two rows carry printing oddities worth knowing about: the 18 in and 20 in sizes share an SWL of 7.6 tonnes despite different mooring wire, and dimension P is larger on the 18 in than on the 20 in. Both are reproduced as printed — confirm with us before designing against them.
Standards
Shipboard bollards of this family were covered by ISO 3913 — Shipbuilding, welded steel bollards, which set material and principal dimensions for nominal sizes 100 to 800 and left welding detail to the maker provided the bollard passed test. ISO 3913 has been withdrawn and is named here because the trade still quotes it, not because it is current.
