Product Description
Dock Fender Anti Collision Durable Long Service Life
Product Overview

D Type Fenders are engineered marine rubber fender profiles developed for vessel-to-structure protection where compact installation, controlled deformation, and resistance to repeated mechanical contact are required. The D-shaped profile provides a relatively large rubber cross-sectional volume within a compact installation envelope, allowing the fender to absorb contact energy while maintaining clearance around quay structures, vessel hulls, floating platforms, and marine access facilities.

Key Features
Compact D-Shaped Geometry for Restricted Installation Areas

The D-shaped cross section is engineered to provide a useful rubber volume while maintaining a relatively compact external profile. This geometry is important in offshore and floating applications where installation space is often restricted by structural steelwork, access platforms, pipelines, ladders, cable systems, or operational clearance requirements.

Marine-Grade Rubber with Environmental Stability

Marine fenders are exposed to environmental conditions that can gradually affect rubber performance. D Type Fenders can be manufactured from rubber compounds formulated for marine exposure, maintaining adequate elastic recovery and mechanical integrity throughout the service period.

Combined Compression and Sliding Performance

D Type Fenders are designed to accommodate combined loading through rubber deformation and surface sliding. The engineering significance of this characteristic is that the fender must withstand both deformation and cumulative wear from repeated vessel movement.

Engineered Fixing and Structural Integration

A marine fender cannot perform correctly if the fixing system is inadequate. D Type Fenders can be supplied with mounting-hole patterns and fixing components according to project drawings, adapted to steel frames, concrete edges, vessel structures, floating pontoons, and offshore platforms.

Applications
  • Offshore Supply Bases and Service Berths: Installed along offshore supply bases and service berths where platform supply vessels, crew boats, and utility vessels operate alongside fixed or floating structures.
  • Floating Pontoons and Marine Transfer Platforms: Used along pontoon edges and floating transfer platforms to accommodate vessel contact while protecting the supporting structure.
  • Offshore Construction and Work Platforms: Integrated into marine construction projects including barges, work platforms, accommodation units, and temporary floating structures.
Case Study: D Type Fender Protection System

An offshore supply base in Southeast Asia implemented D Type Fenders on their floating service berth used by platform supply vessels, crew boats, utility vessels, and small coastal cargo vessels. The continuous rubber profile eliminated unprotected contact gaps and provided a uniform interface between vessels and the berth, resulting in fewer localized coating repairs and improved protection of the berth edge.

Frequently Asked Questions
Can D Type Fenders be used on floating structures subject to continuous movement?

Yes. D Type Fenders are suitable for floating pontoons, barges, service platforms, and similar structures where relative movement occurs between the vessel and the protected structure.

How does rubber hardness affect D Type Fender performance?

Rubber hardness influences deformation and reaction force. A harder compound provides greater resistance to deformation, while a softer compound provides greater deformation under comparable loading.

Are D Type Fenders suitable for continuous seawater exposure?

Yes. Marine-grade rubber compounds can be formulated for prolonged seawater and salt-spray exposure, considering temperature, ultraviolet radiation, abrasion, and expected service duration.

What fixing methods can be used for D Type Fenders?

Common arrangements include bolts, retaining bars, clamps, backing plates, and customized mechanical fixing systems. Fixing dimensions and hole patterns can be manufactured according to project requirements.

Can D Type Fenders be supplied for an existing offshore structure without major modification?

In many replacement applications, the fender can be manufactured according to existing dimensions and mounting positions using drawings, measurements, photographs, or physical samples.
