DIN 82607 is a German industrial standard set by the Deutsches Institut für Normung (German Standardization Institute). It defines technical specifications for double bollards-critical mooring equipment used in marine and port operations. These bollards ensure safe, reliable vessel berthing by securing mooring/towing ropes, aligning with global quality, safety, and compatibility benchmarks.
The DIN 82607 double bollard is a critical mooring and towing fitting for marine applications. Designed to secure vessels at jetties, berths, wharves, and dolphins in ports and harbors, it follows the German DIN 82607 standard.
Key Features
- Structure & Function: Consists of two vertical steel tubes attached to a reinforced steel base. Features ridges to prevent rope movement and may include stopper lugs for rope handling. Some models can integrate with warping rollers.
- Materials: Typically made from cast steel, cast iron, or weldable steel plates. Stainless steel (e.g., AISI 316, AISI 304) options exist for enhanced corrosion resistance.
- Performance: Offers a safe working load (SWL) ranging from 10 kN to 320 kN, with weights spanning 21 kg to 765 kg. Built for durability, with a service life of 15-20 years under proper conditions.
- Surface Treatment: Common finishes include sandblasting (to Sa 2.5), shop primer, and options like galvanizing or anti - rust painting for corrosion protection.
Installation
- Deck Mounting: Bolted/welded to reinforced deck plates. For offshore use, base plates may include anti - vibration pads to reduce fatigue.
- Alignment: Must be positioned to align with vessel mooring points (e.g., bitts on ship decks) for optimal load distribution.
Maintenance
- Inspections: Quarterly checks for paint damage, weld cracks, and rope - wear on ridges.
- Reconditioning: Every 5-10 years, re - sandblast and repaint (or re - galvanize) to restore corrosion protection.

1. What is the primary use of a DIN 82607 double bollard?
It's used to belay (secure) mooring and towing ropes on ships, docks, and offshore platforms, ensuring vessels stay safely alongside berths.
2. What materials are these bollards made from?
Common materials are cast steel, cast iron, or weldable steel plates. Stainless steel (AISI 316/AISI 304) is available for harsh, corrosive environments (e.g., saltwater exposure).
3. Can the bollards be customized?
Yes. Suppliers often offer customizations for dimensions, surface treatments (e.g., specific paint colors), and integration with warping rollers. Certification requests (e.g., specific class society approvals) can also be accommodated.
4. What is the typical service life?
With proper maintenance, they last 15-20 years. Factors like environment (e.g., saltwater vs. freshwater), load frequency, and maintenance (e.g., corrosion protection) impact longevity.
5. How to choose the right size?
Select based on the vessel's size, expected load (SWL requirement), and application (e.g., port, offshore). Check technical specs for dimensions (e.g., tube diameter, base size) and SWL to match your needs.
6. Are installation instructions provided?
Yes. Suppliers include guidelines for deck mounting, ensuring the base is properly secured (e.g., via welding or bolts) to handle mooring forces.
7. Can these bollards resist corrosion?
Yes. Surface treatments like galvanizing, anti - rust painting, or stainless steel construction protect against corrosion, critical for marine environments.
8. What certifications are available?
Most suppliers offer certifications from major classification societies (CCS, ABS, BV, DNV, LR, etc.), ensuring compliance with international marine safety standards.
For specific projects, contact manufacturers to confirm specs, customizations, and certifications to meet your exact requirements.
