Berthing Bollards Saltwater Corrosion Resistant UV Protected Coating High Tensile Strength

Description

Hongruntong Marine Mooring Bollards are purpose-designed mooring components for shipyards, dry docks, and vessel construction facilities, where precise positioning, controlled loads, and high safety margins are essential. Unlike standard port mooring, shipyard operations often involve non-standard load paths, temporary mooring conditions, and frequent adjustments during vessel construction, launching, and repair stages. These requirements demand bollards with superior structural reliability and operational flexibility.

Hongruntong Marine offers mooring bollards with rated capacities from 50KN to 2000KN, manufactured primarily from high-strength cast steel or ductile iron. The bollards feature a solid, one-piece casting structure that ensures uniform stress distribution and eliminates weak points commonly associated with welded assemblies. The carefully designed profile allows smooth rope engagement and controlled force transfer, reducing shock loads during vessel movement.

With excellent resistance to mechanical wear, corrosion, and long-term fatigue, these bollards provide dependable performance throughout all stages of shipbuilding and maintenance. Their durability, adaptability, and safety performance make them a trusted solution for modern shipyards and dry dock facilities worldwide.

Case Study – Shipyard Dry Dock Mooring System

A large commercial shipyard specializing in the construction and overhaul of tankers and bulk carriers (40,000–120,000 DWT) required an upgrade to its dry dock mooring system. The existing bollards had been in service for decades and showed signs of surface wear and reduced load reliability, particularly during docking and undocking operations.

Hongruntong Marine supplied a series of 1000KN and 1400KN cast steel mooring bollards tailored for dry dock use. The bollards were installed along the dock walls and keel blocks, providing secure mooring points during vessel entry, positioning, and maintenance. Special attention was given to rope-contact geometry to ensure compatibility with both synthetic and wire mooring lines commonly used in shipyard operations.

Following installation, the shipyard reported improved control during docking procedures, reduced adjustment time, and enhanced safety for dock personnel. Over multiple docking cycles, the bollards demonstrated stable performance with no structural deformation. The success of this project led to the adoption of Hongruntong Marine bollards as standard equipment for future dry dock upgrades within the facility.

Specifications

Product Features

Precision Oriented Structural Design

The bollards are engineered to provide stable and predictable load behavior, which is critical during ship positioning and construction stages. Reinforced neck sections and optimized load paths reduce stress concentration and improve overall safety during controlled mooring operations.

High Strength Materials for Construction Environments

Manufactured from premium cast steel or ductile iron, the bollards offer high tensile strength, excellent impact resistance, and strong fatigue performance. These properties are essential in shipyards where accidental impacts, uneven loads, and temporary mooring configurations are common.

Smooth and Durable Rope Contact Surfaces

All rope-contact areas are precisely machined and contoured to minimize abrasion and localized wear on mooring lines. This feature extends rope service life and reduces the risk of sudden rope failure during critical operations.

Adaptability to Shipyard Infrastructure

The bollards can be installed on reinforced concrete dock walls, steel structures, or embedded foundations. Their adaptable base design allows integration into both new shipyard construction projects and refurbishment of existing facilities.

Applications

Shipbuilding and Vessel Construction

Used during hull assembly, outfitting, and launching to secure vessels safely at various construction stages.
