Marine Bollards are a simple and cost-effective way to achieve mooring requirements. It is the anchor point for mooring lines to be fixed in order to safely secure vessels alongside jetties/quay, berths, wharves and dolphins in ports and harbours. Mooring bollards are highly stable and provide a safe and secure mooring.
Commonly Used Bollard DesignsSome of the most commonly used bollard designs today are the T-Head, T-Horn, Kidney, Cleat, Double Bitt, Single Bitt, Tricorn and Pillar.
T- head bollard design has a top shaped like a “T". Very prominent in many regions of the world due to its simplicity and it gets the job done well up to 300 tonnes. T-Head Bollards can handle higher line load angels than single bitt and kidney shaped bollards.
other refer it to as the “Staghorn design" as well can accommodate very steep mooring angles.
has a simple design that is suitable when low to medium tidal range is expected. Kidney Bollards offer an economical solution for installations where securing of mooring lines at high angles is not a concern. This style is not recommended when multiple mooring lines will share one bollard as there may be a possibility of an unintentional release due to the shallow lip at the top of the bollard.
are simple type of bollards used for smaller vessels. With a mooring line capacity range from 5 tonnes to 35 tonnes, Cleat Bollards suit marine mooring applications for light commercial use or recreational marina use as well as mounting on vessels.
some call it the “Twin Horn" or “Twin". Small base area is space-saving for small areas. Double Bitt Bollards are useful when high densities of mooring lines are present, this is a better choice for ship mooring and shifting.
also known as “US Style Pillar Bollards" are particularly suitable for applications where tidal range variations are large and can handle steep mooring line angles. They are capable of accepting multiple mooring lines and have been designed to fit onto existing bolt patterns for older US style pillar bollards.
are normally applicable where tidal ranges are small and use for warping operations along berths where vessels need to be re-positioned for loading purposes. Due to their 360 degree line of load range, they can also be placed on jetties where vessels berth on both sides of the jetty structure. Pillar Bollards can withstand use in harsh environments.
