Materials and Manufacturing

Materials and fabrication are key factors affecting the service life of a Yokohama fender. Several factors need to be considered:

Manufacturing materials

Materials used in the manufacture of Yokohama fenders typically include the following:

Rubber: Rubber is one of the common materials used in the manufacture of Yokohama fenders. It has excellent elasticity and abrasion resistance. It absorbs the impact from the vessel and reduces friction loss.

Polyethylene: Polyethylene is also a common material used in the manufacture of Yokohama fenders. It offers corrosion resistance and durability. It meets a variety of complex marine environments.

Foam Core: Some Yokohama fenders include a foam core to provide additional buoyancy and energy absorption, depending on special requirements.

Metal Components: Yokohama fenders often include metal components in their construction. For example, they may have steel cables and steel frames to make them more stable and strong.

Manufacturing process

The manufacturing process of a cross-harbor fender usually includes the following steps:

Preparation of raw materials: Different types of Yokohama fenders require different raw materials. The manufacturer will select the appropriate materials. They will ensure that the materials meet quality standards.

Forming: The fenders undergo a forming process. This process usually involves extrusion or molding to obtain the desired shape and size.

Processing and assembly: The manufacturer further processes and assembles the fenders. This may include adding metal parts, connectors, and other accessories.

Quality Control: Quality control procedures are critical during the manufacturing process. They ensure that each fender meets standards and specifications.

Coatings And Protection: Specialized Yokohama fenders may need extra coatings or protection. This can boost their durability and resistance to corrosion.

Factors affecting service life

Material Quality: The quality of the materials used in manufacturing is critical to service life. Materials of higher quality are generally more durable. They can withstand impact and friction for longer periods of time.

Manufacturing Process: The quality control and precision of the manufacturing process affect the performance and life of the Fender.

Environmental conditions: The environmental conditions in which a fender is exposed can affect its lifespan. These conditions include water quality, water temperature, and UV radiation. Adaptable materials and coatings can extend the service life.

Maintenance and Care: Proper maintenance and care can extend the life of a fender. Regular inspection, cleaning and repair are key.

Environment of use

Yokohama fenders are used in different harbors and climatic conditions. The environment can significantly impact their durability. The following are specific factors:

Type of harbor

Different types of ports may have different effects on the environment. This affects the use of Yokohama fenders. For example, large international ports typically have more vessel traffic and greater vessel tonnage. Therefore, fenders in these ports may face more frequent impacts and friction. Smaller ports or inland harbours may be affected by fewer vessels. They may also have less use for fenders.

Climatic conditions

Climatic conditions significantly impact the lifespan of Yokohama fenders. Different conditions can lead to the following problems:

Temperature: Both high and low-temperature conditions can negatively affect the material properties of fenders. High temperatures may cause the material to deteriorate. Low temperatures may cause the material to become brittle.

Salt Water: Fenders in marine environments may be more susceptible to corrosion. Salt and chlorides in salt water can damage the material’s surface.

Storms and heavy waves: Storms and heavy waves may cause fenders to experience stronger impact forces. This requires stronger designs to cope with extreme weather conditions.

Vessel type and frequency

Different types and sizes of ships put different levels of stress on fenders. Larger cargo ships and tankers can have a greater impact on fenders. Frequent ship traffic can lead to more frequent use of fenders, shortening their lifespan.

Pollution and sewage discharges

Some harbors may be affected by pollution from ships and sewage discharges. Pollutants can corrode fender materials and shorten their life.

Tidal and water level variations

Some harbor areas have significant tidal and water level variations. These variations can cause fenders to experience different stresses and pressures. The design of fenders needs to take these factors into account. This ensures consistent performance.

Maintenance and servicing

Maintenance and care are key factors for ensuring the longevity of your Yokohama fender. We’ve provided tips and best practices for Yokohama fender maintenance and care here.

Regular Inspections: Regularly inspect the appearance and structure of the fender. Look for any visible wear, tear, breakage, or corrosion.

Clean Fenders: Clean fender surfaces to remove attached seaweed, barnacles, and other organisms. This reduces friction and corrosion.

Coating Protection: If applicable, periodically inspect and maintain the fender’s coating. Recoat to prevent corrosion.

Maintain Stability: Ensure that fenders are positioned and stabilized. Prevent them from moving or shifting.

Record Maintenance History: Record fender maintenance history, including repairs, coatings, and replacement parts.

Adjust Maintenance Frequency to Environment: Adjust the frequency of maintenance and servicing to the environmental conditions. This is the environment in which the Yokohama fender is exposed.

Periodic Replacement: Ensure performance by regularly replacing deteriorating fenders. Base the replacement schedule on the manufacturer’s recommendations and actual wear and tear.

Train Personnel: Train port personnel on proper fender maintenance and servicing procedures.

Safety: Ensure the safety of personnel when carrying out maintenance and servicing work. Take appropriate measures to prevent accidents and injuries.
