シングル・ポイント・ムアリング・ホーサー - ジェリーボーグ・マリーン

A mooring hawser is essentially a large cable specifically designed for mooring operations. It’s not the short cable used on ordinary ships, but rather used in single-point mooring or ship-to-ship operations to bear the main tensile force. In many offshore projects, the connection between the ship and the buoy relies heavily on it to withstand continuous tension.

Jerryborg Marine can provide mooring haws of varying strengths depending on the project’s tensile strength. We typically confirm the ship’s tonnage and operating environment first, then recommend the appropriate specifications, rather than providing a generic model.

This type of cable is commonly found in offshore anchorages, single-point mooring buoys, or ship-to-ship transshipment projects. Especially in oil and ore transshipment, where ships don’t dock but connect directly at sea, the hawser is a critical component.

Jerryborg Marine also provides haws when undertaking buoy or fender projects, facilitating a complete solution for clients and eliminating the need to find separate suppliers.

High-strength synthetic fibers, such as nylon or polyester, are commonly used. Different materials have different characteristics; some have high elongation and good cushioning, while others have low elongation and are more stable. The specific choice depends on the project requirements.

Jerryborg Marine will recommend materials based on the client’s operating frequency and stress conditions. For high-frequency ship berthing projects, we will focus more on abrasion resistance and long-term stress performance.

Strength mainly depends on the maximum tensile force of the project. The required breaking strength is usually calculated based on the ship’s tonnage, environmental conditions, and safety factor. It cannot be too low, otherwise there is a risk; nor is it necessary to blindly choose too high, as this will increase costs.

Jerryborg Marine will communicate with the client about the operating conditions before confirming the order. If the client has basic data, we can also assist in verification to avoid selecting the wrong specifications.

After prolonged use, common issues include outer layer wear or localized deformation due to stress. In offshore environments, the effects of salt spray and ultraviolet radiation must also be considered. Therefore, regular inspections are necessary.

Jerryborg Marine conducts basic strength and appearance inspections before shipment. If customers discover any abnormalities later, they can take photos, and we will assist in determining whether replacement is necessary.

The lifespan is greatly influenced by the frequency of operation. Long-term, high-frequency transport projects will experience faster wear. Periodic use will result in a longer lifespan. The key is regular inspection and maintenance.

Jerryborg Marine also reminds customers to perform daily inspections when providing the hawser. With proper use, it can provide stable service for a considerable period.
