What are the commonly used mooring bollards?
Mooring bollard is fixed on the deck or dockside for mooring ropes. Generally made of metal casting or welding. It mainly includes single bitt bollard, double bitt bollard, T head bollard, and staghorn bollard. Common specifications include 50KN, 150KN, 250KN, 350KN, 450KN, 550KN, 650KN, 750KN, 1000KN, 1500KN, 2000KN, etc.
T Head Bollard
T head bollards are shaped like a “T”, hence the name. It has simple design and low maintenance cost. In addition, its base can be designed into different shapes according to needs, such as circular, semicircular, square, etc. It’s suitable for use in various terminals and ports.
Single Bitt Bollard
The single bitt bollard is a very common type of bollard. It is usually made of cast steel or ductile cast iron. And it is suitable for mooring at large angles, especially when the tidal range is large.
Double Bitt Bollard
Double bitt bollard is a further improvement on the single bitt bollard. As it has double corners, it can accept multiple mooring lines without disturbing the mooring lines of adjacent vessels. Besides, because its base is narrow, it is especially suitable for use at docks with limited space.
Staghorn Bollard
Staghorn bollard is very commonly used. It can accommodate very steep mooring angles. It is especially suitable for areas with large tidal changes and multi-purpose docks.
Kidney Bollard
The design of kidney bollard is very simple, and the size range can basically cover the needs of various docks, so it is the most common type of bollard. This type of bollard is suitable for docks with small tidal range.
