125–250mm Inclined Double Bitt Bollard | CB/T 169-2011 Type B Welded Mooring Bollard for Ship Deck

Product Overview

CB/T 169-2011 Type B inclined double bitt bollard is designed for medium to heavy-duty ship mooring applications.

The inclined double-post structure increases friction and prevents rope slipping or accidental release during vessel movement.

It is widely used on cargo vessels, barges and harbor service ships requiring stable and high-load mooring performance.

Quick Specifications

• Nominal Diameter: 125–250 mm → Determines rope compatibility
• Type: Type B (double base plate) → Improved load distribution and structural stability
• SWL Range: 19.5–59 kN → Load capacity reference
• Structure: Inclined double bitt → Anti-slip rope holding
• Material: C-Mn Steel / Stainless Steel → Strength & corrosion resistance
• Surface: Sa2.5 + epoxy coating → Marine corrosion protection
• Installation: Welded base → Strong load transfer to deck
• Certification: CCS, NK, BV, ABS, DNV, LR, KR, IRS, RS, RINA, CRS, Makers Test Certificate

Main Technical Parameters (CB/T 169-2011 Type B)

Engineering Design Logic

Load transfer path: Rope → Bollard Posts → Base Plate → Deck Structure.

Inclined posts increase friction and reduce rope slip under dynamic vessel movement.

Double base plate improves load distribution and structural stability.

Why Inclined Bollard Design?

Prevents rope slipping → Higher mooring safety

Improves holding force → Better stability under vessel movement

Reduces accidental release → Safer operation

Suitable for dynamic conditions → Cargo vessels and barges

Structure

Inclined Double Posts | Double Base Plate | Reinforcement Plates | Welded Structure

Custom Attributes

• Inclined posts → Anti-slip performance
• Double base plate → Higher structural stability
• Welded fabrication → Reliable load transfer
• Smooth surface → Protects rope
• Optional stainless steel → Corrosion resistance

Selection Guide

Step 1 – Select diameter → Based on rope size

Step 2 – Confirm rope type → Wire / fiber

Step 3 – Confirm load → Based on SWL

Step 4 – Select Type → Type B for heavy-duty application

Step 5 – Confirm certification requirement

Inquiry Guide

Please provide rope diameter, rope type, vessel type, installation position and certification requirement.

How It Works

Rope wraps around inclined posts → friction increases → load transfers to base → ensures secure mooring without slipping.

Applications
