Marine Mooring Bollards.

Buoder Marine Fendering System / Products / Marine Mooring Bollards
Marine mooring bollards and cleats are used to secure vessel to dock by mooring lines. The load rating the bollards or cleats is confirmed by these mooring line load capacity. The mooring line load is dependent on vessel, current, wind, and wake etc. Buoder design and manufacture many types marine mooring bollards and cleats.

Bollard Types & Selection

Buoder marine mooring bollards have been refined with Finite Element Analysis to optimize to the geometry and suitable anchor layout. Out mooring bollards are also physically tested to ensure the product exceeds our designed expectations. Even at full working load and greater rope angles, our mooring bollard remain highly stable and provide a safe and secure mooring.

Buoder marine mooring bollards are available in a wide range of shapes, load ratings, and materials, of which no single combination can satisfy all customers. Buoder commonly used style of bollards are the Single Bitt, Double Bitt, T-head, Staghorn, Kidney, Pillar, and marine cleats.

Mooring bollard should be selected and arranged according to local authorities finalizing any type of bollards, it is suggest to consider below points.

  • Mooring pattern
  • Changes in draft due to loading and discharge
  • Wind and current forces
  • Swell, wave and tidal forces
  • Mooring line types, size and angles
  • Ice forces (where relevant)

A general guidelines to mooring load can be followed the below table.

Design Stanard

Buoder Bollards are designed based on BS 6349, Part 2:1998 Marine structures & PIANC 2002.

Installation Method

Various option exist for the installation of marine mooring bollards and cleats. The most common method is utilizing cast-in-place embedded anchors. Alternate methods include through bolting with cast in pipe sleeves, or epoxy-in anchors for retrofitting existing structures.

Bollard Material

Mooring bollards are typically manufactured using the sand casting method with the material of choice being either cast steel or ductile iron. We commonly use the below material.

Cast Steel:
A27 Gr.65-35, A27 Gr.70-36, A27 Gr.70-40, A148 Gr.80-50 (ASTM Standard); 3755 Gr.230-450, 3755 Gr.270-480, 3755 Gr.340-550 (ISO Standard)

Ductile Iron:
A536 Gr.65-45-12, A536 Gr.80-55-06 (ASTM Standard); 1083 Gr.450-310, 1083 Gr.550-350 (ISO Standard)

Mounting Hardare

Mooring bollard should be installed using our suggested hardware diameter and grades. Mooring bollard anchors are usually supplied as partially threaded bars with each end of the anchor having enough threaded length. All carbon steel anchors and nuts and plate washers are supplied hot dip galvanized.

Our standard anchors are supplied according to the below specification.

Item Standard Grades ISO Grades
Bolts/Anchor Rod ASTM F1554 Gr.105 ISO 898 Gr.8.8
Nuts/Heavy Hex ASTM A563 Gr.DH ISO 898 Gr.8
Round Wahser ASTM F436 ISO 887
Square Plaste ASTM A36 ISO 630

    Coating

    Bollard Finishing are an essential part of the system as it prevents excessive corrosion that can weaken a bollard. Our Bollards are supplied with Blasting, Painting according to below specification.

    • Blasting: Shot blast to SA2.5 (ISO 12944)
    • Primer: Zinc Primer (50-75 Microns)
    • Painting: Black bitumen or Coal tar epoxy according to Class C5M (300-375 Microns)
