What Are Double Bitt Bollards?
Double Bitt Bollards feature two parallel vertical posts, or “bitts,” which allow multiple mooring lines to be securely tied off. Their design is well-suited for situations where ships require enhanced line control and high-load capacity. They offer a stable, durable solution for docks that experience frequent vessel movement and changing environmental conditions.
Applications of Double Bitt Bollards:
- Industrial ports handling cargo, tankers, and container ships
- Busy harbors with high vessel traffic
- Heavy-load berthing zones for commercial and naval ships
- Multi-line mooring for large vessels requiring high tension support

Why Choose Double Bitt Bollards From Marine Structures?
High Load Capacity for Large Vessels
Our Double Bitt Bollards are designed to handle Safe Working Loads (SWL) ranging from 15 tons to 300 tons, making them ideal for mooring anything from smaller vessels to large cargo ships and tankers. The dual-post configuration ensures that multiple lines can be secured while distributing tension evenly.
Superior Stability and Security
The parallel posts provide added stability when securing mooring lines, minimizing the risk of slippage or sudden stress failure. The design ensures that the bollard can withstand the dynamic forces caused by tides, currents, and vessel movement.
Durable Materials and Corrosion Resistance
Marine environments are tough, but our Double Bitt Bollards are tougher. Manufactured with premium materials and finished with marine-grade protective coatings, our bollards resist corrosion, wear, and environmental damage, ensuring long service life with minimal maintenance.
