Product Description
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

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
Cargo vessels | Barges | Harbor service ships | Deck mooring
