Bollards

Product catalog summary
Introduction
Trelleborg Marine Systems provides a diverse range of bollards aimed at improving port and vessel efficiency through advanced technologies. Their solutions leverage global expertise and local insights to enhance commercial port operations.

Bollard Range and Technical Information
The company offers seven bollard styles, crafted for durability and corrosion resistance, primarily using spheroidal graphite ductile iron. Cast steel options are available but require more maintenance.

Bollard Materials and Manufacture
Ductile cast iron is preferred over grey cast iron and cast steel due to its superior strength and corrosion resistance. Bollards are designed with a safety factor of 3.0 and adhere to international standards.

Bollard Selection and Installation
Bollard selection is based on application needs, including capacity and rope angles. Installation guidelines ensure secure anchoring and optimal performance.

Bollard Maintenance
Regular maintenance is essential for bollard longevity. Trelleborg offers maintenance instructions and high-performance coatings to protect against environmental damage.

Conclusion
Trelleborg emphasizes a comprehensive approach to port engineering, offering services from consultation to support, underscoring their leadership in marine technology.
Material Specifications
Bollards are manufactured to high standards, with coating options like zinc oxide primer and epoxy. Hot Dip Galvanized coatings and stainless steel anchors are available upon request.

Selection Criteria
Bollard selection should consider local regulations, mooring patterns, and environmental forces. Mooring loads should be increased by 25% in adverse conditions.

Mooring Line Angles
Bollards can handle horizontal angles of ±90° and vertical angles up to 75°.

Installation Options
Bollards can be recessed or surface mounted, with recessing preferred to prevent loosening.

Maintenance Recommendations
Regular inspection and maintenance are crucial. Protective coatings and structural components like grout and bolts require regular checks.

Torque Requirements
Detailed torque requirements are provided to ensure optimal performance and prevent stress on structures.
Specifications
Specifications for various bollard types include bolt sizes, pretension forces, and torque requirements under different loading conditions. K values for bolts are specified based on conditions.

Standard and Custom Designs
Trelleborg offers standard and custom bollard designs, with engineering calculations for installations.

Jetty Design and Construction
Engineers should assess bollard inclusion in jetty designs, recommending a concrete strength of 40MPa.

Bollard Selection
Bollard selection depends on vessel size, weather, and jetty configuration, with layout analysis being the designer's responsibility.

Technical Support and Materials
Trelleborg provides technical support and recommends non-shrink grout with a minimum strength of 60MPa. Alternative bolt materials require re-engineering.

Breakaway Bollards and Load Testing
Breakaway bollards are discouraged due to safety concerns, and physical load testing is not conducted due to existing safety factors.

Codes and Guidelines
The document references several codes and guidelines for mooring system design and approval.

Disclaimer
Trelleborg disclaims responsibility for errors and advises obtaining detailed specifications before construction. The document is subject to change without notice.

Bollard Range And Technical Information However, with cast steel remaining popular in specific regions Trelleborg also manufacture cast steel bollards which provide high impact resistance but require regular painting to prevent corrosion. Trelleborg bollards come in many popular shapes and sizes to suit most docks, jetties and wharves. Standard material is spheroidal graphite (commonly called SG or ductile iron) which is both strong and resistant to corrosion, meaning Trelleborg bollards enjoy a long and trouble free service life. The shape of Trelleborg bollards has been refined with finite...

Bollard Materials and Manufacture Design Bollards and holding down bolts are designed with a minimum factor of safety against failure of 3.0 for Spheroidal Graphite (SG) cast iron material grade 65-45-12. Designs are typically based on the following: Standard Marine structures Ductile cast iron is the preferred material for all bollard applications. Grey cast iron is cheaper per unit weight, but the need for thicker wall sections and poor impact strength outweighs this. Cast steel remains popular in some countries but needs regular painting to prevent corrosion. Mechanical equipment design Detailed...
