Roller Fender High Energy Absorption Low Reaction Force Built To Last

Roller Fender High Energy Absorption Low Reaction Force Built To Last

Description

Roller fenders are a specialized type of marine fender designed to absorb kinetic energy and reduce impact forces during vessel berthing, particularly at angled approaches. Unlike traditional fixed fenders, roller fenders incorporate a rotating barrel or wheel that turns upon contact with a vessel’s hull. This rolling action significantly reduces friction, preventing paint damage and minimizing stress on both the dock structure and the vessel. Constructed from heavy-duty steel frames and high-performance rubber or polyurethane rollers, they are corrosion-resistant and designed for long service life in harsh marine environments. The roller mechanism is sealed to prevent ingress of saltwater and debris, ensuring minimal maintenance. They are particularly effective in narrow entrances, tidal harbors, and lock gates where vessels may approach at a shallow angle, requiring both impact absorption and smooth redirection.

( Case: At a busy commercial port, frequent tidal currents forced cargo vessels to approach the entrance channel at angles of 15–20 degrees. The port authority installed a series of high-capacity roller fenders along the lock gate entrance. When a 30,000 DWT bulk carrier approached, the roller fenders absorbed the berthing energy while guiding the vessel smoothly into position. The rotating action prevented scraping of the vessel’s hull, reducing paint maintenance costs by 40% over the next year. Port operations reported zero incidents of hull damage after installation, and the fenders required only routine inspections twice a year. )

Features

High Energy Absorption
Roller fenders are designed to handle substantial kinetic energy generated when a vessel approaches the dock. The robust roller structure compresses under load, dissipating energy efficiently and protecting both the vessel’s hull and the dock’s infrastructure. This high absorption capacity is especially important for larger ships and high-traffic ports where berthing speeds can vary.

Low Reaction Force
While absorbing energy, roller fenders also maintain a low reaction force. This means that when a vessel makes contact, the pushback against the hull is minimal, reducing stress on the ship’s frame and improving docking safety for both vessel and crew.

Smooth Rolling Action
Unlike static fenders, roller fenders rotate upon contact, creating a smooth, guiding motion. This rolling action helps vessels align naturally into position without sudden stops, making berthing easier for captains and reducing the risk of scraping.

Reduced Hull Friction
Because the rollers spin, surface friction between the fender and the vessel’s hull is greatly reduced. This prevents paint damage, gelcoat wear, and structural abrasion, extending the life of the vessel’s exterior finish.

Applications

Container Barge Berthing Points
In shallow-water container transfer points, roller fenders help small cargo barges berth smoothly, preventing impact damage to lighter vessels and floating docks.

Floating Pontoon Systems
Roller fenders installed on floating pontoons provide flexible and mobile docking solutions for varying water levels, ideal for tidal regions.

Maintenance Support Vessels in Offshore Wind Farms
Roller fenders protect crew transfer vessels when docking against offshore wind turbine platforms, ensuring safe boarding in open sea conditions.

The basis for our strategy was a detailed analysis of major long-term market trends. We identified three megatrends, which will affect our different businesses over the next years: consolidation, emerging markets and speed.

• Consolidation in our supplier, manufacturer and customer base as well as in our competitive environment will continue. Size will become a critical success factor in the future. Consequently, we need to grow our businesses.
• We expect the shift of growth from mature to emerging markets to continue. As a result, we need to expand our already strong footprint in these markets over the coming years.
• We anticipate highly dynamic market evolution, and faster decision-making by suppliers, customers and competitors. In addition, further digitalization will lead to changes in our market environment. We therefore need to continue simplifying our processes and increasing our operational excellence.
