How To Repair Damaged Rubber on a Floating Hose (With GIFs and Video)

Belzona Rubber Repair for Floating Hoses

Cold-curing elastomers offer an alternative solution for floating hose repair. Asset owners can carry out repairs without the need for specialist tools, thus eliminating the need for hot work. This ensures a fast return-to-service, whilst offering a versatile repair with durability and elasticity.

Cold-curing elastomers offer solutions for a range of marine and industrial applications. These cold-cure polyurethane materials are suitable for marine floating hoses, offshore loading/discharge hoses, floating dredge hoses, floating oil hoses, submarine mainline LPG hoses, FPSO floating hose repairs as well as rubber fenders and other rubber components of equipment used across various industries.

Asset owners can select Belzona elastomers based upon the nature and severity of the damage on the rubber components, the level of urgency, the system pressure and operating temperature. The following table provides guidance on how to select products to repair damaged rubber components.

MAIN SYSTEM REQUIREMENT	Belzona 2111 (D&A Hi-Build Elastomer)	Belzona 2211 (MP Hi-Build Elastomer)	Belzona 2311 (SR Elastomer)
Rebuilding-grade	YES	YES	YES
High abrasion resistance	YES
General repairs		YES
Rapid repairs			YES

Belzona Elastomers: Put It to the Test

Belzona has put a range of our cold-cure polyurethane materials to the test to assess their superior performance for repairing and protecting rubber components.

• Quick Return-to-Service: Belzona solutions allow applications in situ, meaning it is less time consuming for disassembling equipment. In addition, for emergency repairs, Belzona 2311 (SR Elastomer) can achieve full mechanical cure in 50 minutes at 25°C (77°F).
• Excellent Adhesion: Belzona elastomers can adhere to a variety of substrates. Apart from rubber, they can adhere to concrete and steel. Their excellent adhesion properties ensure long-term repair and protection.
• Flexibility: During operations, equipment is subject to extensive tensile and tearing forces. When tested in accordance with ASTM D412, Belzona elastomers demonstrate outstanding elongation properties. For example, Belzona 2211 (MP Hi-Build Elastomer) exhibits elongation of up to 1000%. Belzona 2111 (D&A Hi-Build Elastomer) exhibits elongation of up to 550%.  
• Abrasion and Impact Resistance: Belzona carried out in-house testing to measure the abrasion resistance of its highly abrasion resistant materials. The testing confirms the durable repairs and long-term protection that Belzona elastomers can offer.
• Application Versatility: Belzona elastomers are versatile, applicable for various repair scenarios and environments. Belzona elastomers are easy to mix and apply, and are able to adhere to a variety of substrates. These cold-cure polyurethane materials provide effective solutions for industrial maintenance.

 

 

 

 

 

 

 

 

 

 

 

 

Step-by-Step Guide: How to Repair Damaged Rubber on a Floating Hose with Belzona Elastomers

In this blog, we demonstrate how to use Belzona 2211 (MP Hi-Build Elastomer) to repair damaged rubber on a floating fuel hose. The damage on the rubber was due to collisions from ship propellers during fuel loading.

Step 1 – Terminate the Tear on the Damaged Hose

Use a sharp knife to create a sound edge terminated square or undercut on the floating hose.

Step 2 – Remove Loose Material from the Floating Hose

Cut away all loosely adhered material on the floating hose and provide an undercut surface. If required, use pliers to help pull the damaged rubber and aid in the undercut. If there is wet reinforcement fabric underneath, allow it to dry before proceeding to further steps.

Step 3 – Prepare the Surface before Applying Belzona Elastomers

Use a rotary wire brush or Belzona roughing brush to abrade the area of damage, the undercut surfaces, and the perimeter of existing, sound substrate until a woolly finish is achieved. Then, brush away loose contamination and use an appropriate cleaner or degreaser to clean the area. Belzona recommends consulting the Instructions for Use for an appropriate selection of cleaner or degreaser.

Step 4 – Define the Repair Area

Use masking tape to define the repair area. This step ensures a clean finish after the application is completed.

Step 5 – Apply Conditioner Over the Repair Area

Apply a thin layer of Belzona 2911 (Elastomer QD Conditioner) or Belzona 2921 (Elastomer GP Conditioner) to condition the repair area. The suitability of the conditioner depends on the substrate and application environment. Belzona recommends consulting the Instructions for Use or contacting an authorised Belzona Distributor for further guidance regarding conditioner selection.

Step 6 – Mix and Apply the Product

Mix Belzona 2211 (MP Hi-Build Elastomer) until the material is of an even colour and consistency. Wet out the appropriate length of Belzona 9341 (Reinforcement Tape) with the mixed Belzona 2211 (MP Hi-Build Elastomer) and apply this to the repair area.

Step 7 – Rebuild Profile of the Floating Hose

Contour Belzona 2211 (MP Hi-Build Elastomer) to the correct profile using a Belzona applicator.

Step 8 – Remove the Tape

Once the application is completed and the product covers all the repair area, remove the tape and allow the product to cure.
