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 Bollard are highly stable and provide a safe and secure mooring.
ESC marine systems operation provides bollards in a range of design profiles, sizes and mooring line capacities to suit all mooring system applications. Commonly used style of bollards are T-Head, T-Horn, Kidney, Cleat, Double Bitt, Single Bitt and Pillar. Mooring bollard should be selected in consideration with the mooring pattern, changes in draft due to loading and discharge, wind and current forces, swell, wave and tidal forces, mooring line types, size and angles ice forces (where relevant). Ductile iron, cast steel and stainless steel are some of the main materials used to make marine bollards.
Generally, design of a bollard should have a thicker diameter at the top (head / tip of the structure) to make it harder for the mooring lines to escape accidentally. It is important to provide a solid anchor point for mooring ropes. Certain designs have double bollards for ropes to be cross-fastened. Such an arrangement would provide a tighter connection. Single and double designs are both available in the market today.
Besides size & design, bollards are also categorized by their grade and mooring capacities. Furthermore, durability is a factor when choosing a suitable bollard design as maintenance is something that end user should be considered. To spot possible deterioration and to ensure that bollards are working well a continual durability testing and inspection should be done to ensure mechanical performance are maintained.
Installation of marine bollards are generally simple. ESC engineers assist its clients in determining all the dimensional requirements and discuss suggestions in order to guarantee the mooring processes are safe.
Some of the most commonly used bollard designs today are the T-Head, T-Horn, Kidney, Cleat, Double Bitt, Single Bitt and Pillar.
“Tee Bollard”, “T-bollard”, 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.Horn Bollards other refer it to as the “Staghorn design” as well can accommodate very steep mooring angles.
