Selection & Inquiry Guide

Step 1 – Confirm the required profile: DD, DC or DO-B according to vessel / dock geometry and replacement requirement.

Step 2 – Confirm section size and total length. For performance-based selection, use the DC 40% table only where the selected profile and length correspond to the published series.

Step 3 – Provide installation drawing, fixing-hole arrangement, support material and available edge distance.

Step 4 – State operating contact direction, abrasion condition, expected vessel movement and any replacement-interchange requirement.

Step 5 – Confirm quantity, documentation, inspection scope and delivery destination.

Key Engineering Advantages

• Compact D-profile geometry is suited to limited installation depth and vessel-side / frame-dock arrangements.
• DD and DC center-opening choices allow the same outer profile concept to be matched to different stiffness and installation requirements.
• The supplied DC series provides directly tabulated 40% reaction-force and energy-absorption data rather than relying only on descriptive claims.
• Profile lengths and fixing arrangements can be adapted to the actual support structure subject to engineering verification.

Installation & System Interface

D-profile fenders are normally fixed to steel or concrete support structures through bolted or project-specific mounting arrangements. Final bolt size, hole spacing, backing structure, edge distance and local reinforcement must match the selected profile, service load and support material.

Inspection & Documentation

Baseline quality control includes visual inspection, dimensional verification and rubber physical-property testing. Where a quantified reaction-force / energy-absorption table is part of the agreed product specification, full-scale compression testing can be included in the project ITP to verify the guaranteed performance under defined test conditions.

PIANC Fender Guidelines 2024 (MarCom WG211) are used as the current engineering reference for fender-system design, manufacturing and testing principles. Type approval, product certification, third-party witnessing and class documentation are stated only when the corresponding scope has been agreed and documented.

FAQ

Q1: What is the difference between DD and DC fenders? — Both use a D-shaped outer profile. DD uses a D-shaped internal opening, while DC uses a circular center bore.

Q2: Can the listed 40% DC performance be applied to every D-profile variant? — No. Use the published values only for the corresponding DC series unless a separate performance verification is provided.

Q3: Can custom lengths be supplied? — Length and fixing arrangement can be discussed for the project, but performance and structural fixing should be verified for the final configuration.
