How To Repair Damaged Rubber on a Floating Hose

INTRODUCTION TO FLOATING HOSE DAMAGE & REPAIR

Floating hoses and other rubber marine components aren’t afraid of a few bumps and bruises! On the contrary, their robust designs mean they receive significant impact and wear during their lifespan, but continuous rips and tears can lead to severe deterioration.

This can stem from fishing vessels and other boats repeatedly impacting the hoses, or even from neighbouring ship propellers gouging chunks and scoring deep incisions during the fuel loading and unloading processes. Depending on the size and depth of the damage, the floatation element of the hoses can be jeopardised – resulting in submersion of the line.

Considering the expense of replacement, as well as the time associated with decommissioning and installation, repair options must be cost-effective.

Traditional Repair Solutions

The most traditional rubber repair technique within the industry is vulcanisation. This comprises heat and pressure being applied to rubber components, creating a strong chemical bond. Whilst this does offer a long-lasting repair, the process too frequently relies on very specific environmental conditions and equipment. Altogether, vulcanisation requires time for a specialised crew and equipment to be brought on site, necessitating long shutdowns.

Belzona’s Solutions for Floating Hoses

Cold-curing elastomers offer an alternative solution to this traditional repair. They can be applied in situ without the need for specialist tools, thus eliminating the need for hot repair processes. This ensures a fast return to service, whilst offering a versatile repair with durability and elasticity built in.

Application technique and Belzona product selection should be made based upon the nature and severity of the damage, the time available for work, the system pressure and operating temperature. For example:
