Types of marine bollards

Types of marine bollards

Marine bollards are strong posts used on harbors, docks, ships, and offshore facilities. They provide a secure point for mooring boats and ships. There are several types of marine bollards, each designed to suit different purposes and environments.

• Corner bollards: These marine corner bollards are mainly used to protect corners from bumping or crashing. They are installed on the corner walls of parking lots, warehouses, or loading docks. Corner bollards come in different heights and materials.
• Deck and Docking bollards: These are marine bollards that are mounted on the deck of a ship or on a dock. They are used for securing a vessel during docking or berthing. Deck and docking bollards come in various designs.
• Traffic bollards: These types of marine bollards are used to control traffic. They are installed to prevent vehicles from accessing certain areas. Traffic marine bollards can be retractable or removable.
• Fairlead bollards: These marine bollards are used to guide mooring lines. Fairlead bollards reduce the wear and tear of the mooring lines.
• Pin bollards: These marine bollards are used to secure vessels in a perpendicular position. They are made of steel rods. Pin bollards are installed at the edge of a dock.
• Hurricane bollards: These marine bollards are designed to protect critical infrastructure from storm surges and flooding. They are installed around buildings and coastal facilities. Hurricane bollards are usually made of concrete.

Specifications and maintenance of marine bollards

Here are the specifications of marine bollards to consider when buying marine bollard accessories.

• Load capacity: Bollards are designed with a load rating that can accommodate vessels' mooring lines. This capacity helps to reduce marine infrastructure damage.
• Height and size: The bollard size and height should be proportionate to the berth and vessel size. Generally, larger marine bollards are easier to use and more visible.
• Design and type: Different types of marine bollards have unique features suited for various situations. For example, a T-head bollard is ideal for heavy-duty applications.
• Material: Marine bollards are made from different materials like steel, cast iron, and concrete. Each material has unique benefits and features that make it suitable for various applications.

Here are some marine bollard maintenance tips.

• Perform regular inspections to identify any signs of wear and damage.
• Marine bollards should be cleaned regularly to remove dirt, marine growth, and debris.
• Users should apply protective coatings to marine bollards to prevent rust.
• Users should ensure the fasteners and fittings are secure to prevent the marine bollard from becoming loose.
• Users should trim the mooring lines regularly to prevent entanglement.

How to choose types of marine bollards

It is important to choose marine bollards carefully because they are essential for the safety and security of ships during docking and mooring. Here are several factors to consider when selecting marine bollards:

• Location:

  The marine environment's characteristics are essential when choosing a bollard for a specific location. For instance, a coastal area with high tides and strong currents needs a robust and durable bollard, while a marina with calm waters requires less resilient marine hardware.

• Material:

  One of the key factors when choosing a marine bollard is its material. It should be corrosion-resistant and durable. A stainless steel bollard is a common choice because of its strength and resistance to corrosion. However, the initial cost may be high. Cast iron bollards are affordable but require regular maintenance to prevent rusting and corrosion.

• Design:

  Various designs serve different purposes. A rounded-head bollard has a rounded head that minimizes line wear. A T-head bollard has a T-shaped head that provides a good lead for mooring lines. A double bitt bollard has two vertical posts for more substantial mooring needs.

• Size:

  The marine bollard's size should be proportional to the vessels using it for mooring. Larger ships require more oversized bollards to handle the increased load and stress during docking.

• Installation:

  Buyers should consider the ease of installing the marine bollard. Some types require additional reinforcement or special mounting techniques, increasing the time and cost of installing them.

• Maintenance:

  Different types of marine bollards require different maintenance levels. Buyers should choose a type with minimal maintenance requirements to reduce the long-term costs and efforts of maintaining the bollard.

• Load capacity:

  Different types of marine bollards have distinct load capacities. Buyers should choose a type with a load capacity greater than the maximum mooring line tension expected in the location.

How to DIY and Replace Types of Marine Bollards

Replacing marine bollards is a straightforward process that can be accomplished with the right tools and basic construction skills. Here are the steps to take:

• Choose the Right Bollard: The new bollard should be similar to the old one in size, type, and material.
• Prepare the Site: The area around the old bollard should be cleaned. Any debris, dirt, or marine growth should be removed.
• Remove the Old Bollard: The old bollard should be unscrewed or cut off if it was welded.
• Check the Condition of the Concrete: Check for cracks or damage after the old bollard is removed. If the concrete is damaged, it should be repaired before installing the new bollard.
• Positioning the New Bollard: The new bollard should be placed in the position where the old one was.
• Securing the New Bollard: If the bollard is not made to be embedded in concrete, it should be bolted to the deck. The bolts should be sealed to prevent water ingress.
• Check for Stability: The bollard should be checked to ensure it is stable and secure.
• Cleaning: Once the new bollard is installed, the area should be cleaned again.

Q and A

Q1: Where are marine bollards placed?

A1: Marine bollards are typically placed along the waterfront, harbors, docks, and piers. They are positioned at various locations where vessels require mooring to the dock or shore.

Q2: What is the purpose of a marine bollard?

A2: A marine bollard is a post or pillar on a dock or harbor designed for ships to moor. Marine bollards are an essential part of port infrastructure, providing a safe and reliable point for ship berthing.

Q3: How do marine bollards work?

A3: Marine bollards are typically placed on docks or piers, and ships can tie ropes to these heavy-duty posts to secure themselves to the land. This mooring system ensures that vessels remain in a fixed position, minimizing movement and reducing the risk of damage or accidents.

Q4: What are marine bollards made of?

A4: Marine bollards can be made of different materials depending on the type and application. The most common materials are concrete, cast iron, and steel. Concrete marine bollards are typically used for smaller ports and are cost-effective. Cast iron and steel marine bollards are used for larger ports and are more durable and robust.
