Comprehensive Guide to Fender Handling and Maintenance


Fenders are vital for safety in marine transport. Handling and maintaining them is key. It keeps ships and terminals safe. Fenders absorb collision forces. They do this between ships or between ships and terminals. This prevents possible damage.

Jerryborg Marine specializes in developing, producing, and selling pneumatic fenders. We design and produce our fenders to meet international standards and industry norms. This ensures that they are safe and reliable. In the following article, we will take you through some tips on handling and maintenance of fenders.

Understanding Pneumatic Fenders

Pneumatic fenders are devices. They use compressed air as a cushion to protect vessels from each other or the dock. This type of fender is wrapped in tough rubber and filled with compressed air. It absorbs and spreads the force of a crash, reducing damage to the vessel and marina. The design of pneumatic fenders allows them to withstand repeated impacts without damage. This makes them a vital piece of safety equipment for marine operations.

Pneumatic fenders are used in a wide range of applications, including but not limited to:

Ship-to-ship operations: Pneumatic fenders prevent collisions. They do so during the transfer of cargo or fuel from one vessel to another.

Berthing: It helps the ship to approach the quay smoothly. Also, it reduces the damage to the ship and quay from collision.

Temporary berthing: It provides a temporary and safe berthing. There are no fixed quay facilities.

High tidal variations: Pneumatic fenders provide additional safety in areas with high tidal variations.

The advantages of choosing Jerryborg’s pneumatic fenders for offshore operations include:

High durability: High-quality materials and strict manufacturing standards are used. They ensure the fenders keep their performance. This is true even in extreme conditions.

Low Maintenance Requirements: Pneumatic fenders are made for easy maintenance and long-term use. They cut maintenance costs and labor.

Flexible Deployment: It is quick and easy to deploy. It adapts to different maritime needs and improves efficiency.

Safety and security: It will reduce the risk of collisions. It will protect vessels and terminals, as well as personnel and assets.

Installation process

Installing pneumatic fenders is a process that requires precise and careful handling. The following is a step-by-step installation guide that emphasizes safety and efficiency:

Preparation stage: Confirm the installation site. Clear the installation area to ensure it is free of obstructions. Inspect fenders and accessories. Make sure they have no damage and that all the fittings are there.

Positioning: Find the exact location to install the fender. Do this to match the needs of the vessel and marina.

Fixings: Attach the fender to the intended position using suitable fixings, like ropes or anchors. This will ensure a secure fixing.

Inflate: inflate the fender at the correct pressure according to the manufacturer’s instructions. Over-inflation or under-inflation may affect the performance of the fender.

Inspection: After inflating, fully inspect the fender. Make sure there are no air leaks. Also, check that the fender is in the right position.

Final Confirmation: After installation, reconfirm that the fender is fixed. Check the air pressure too. This is to ensure safety and effectiveness in use.

Maintenance and Inspection

To keep your pneumatic fender working well and prevent unplanned downtime, you must do regular maintenance checks. Here are some basic tips for maintenance and inspection:

Regular Inspection: Inspect the fender fully at regular intervals (e.g. monthly or quarterly). This includes an appearance check, air pressure check, and accessory check.

Air Pressure Adjustment: Adjust air pressure as the temperature changes. Do this to keep the pressure inside the fender in the recommended range.

Cleaning of fenders: Clean fender exteriors often. This removes sea life and dirt. It prevents damage.

Damage Repair: For minor damage, take repair measures promptly. This will stop the damage from expanding.

Replacement of fittings: Inspect all attachments and connectors. Replace them right away if they are worn or damaged.

Record and report: Record the results of each inspection and maintenance. Any abnormalities should be reported promptly and dealt with.

Troubleshooting Common Problems

When using pneumatic fenders, you may encounter common problems. Here are some and their solutions:

Unstable air pressure or air leakage: Check all connections and valves. Ensure they are tight. Also, check the fender for visible damage or holes. Use a repair kit to patch small perforations or cracks.

Worn or cracked fender surfaces: Clean and inspect fender surfaces regularly to prevent contact with sharp objects. For minor cracks, special glue can be used to repair them.

Loose fender fixings: Check the ropes, chains, or anchors that hold the fender. Adjust or replace them as needed to keep the fender stable.

Properly handling, storing, installing, and maintaining pneumatic fenders is vital. It is key for safe marine transport. Pneumatic fenders are a key facility. They reduce the effects of collisions between ships or between ships and terminals. They protect ships and port facilities. Follow professional installation guidelines. Also, stick to regular maintenance schedules. Doing so will greatly extend the service life of your fenders. It will also ensure that they perform well when it matters. Also, timely troubleshooting and maintenance cut disruptions. They also boost performance. This keeps offshore operations running smoothly. So, every maritime professional should know how to properly handle and care for pneumatic fenders. It should be a daily practice.


Set the inflation pressure according to the manufacturer’s recommendations. For example, Jerryborg’s recommendations account for the effects of the environment and temperature where the tire will be used. Check regularly to ensure that the air pressure is within the recommended range.

Use a mild detergent and a soft cloth or brush to clean the fender. Avoid any chemicals that may harm the fender material.

Maintenance intervals depend on the frequency of use and environmental conditions. You should do a thorough inspection and maintenance. Do it at least once every three months.

Minor damage can be repaired using specialized repair materials. For serious damage, contact your supplier or Jerryborg. Or, contact a professional to assess and replace it.
