FENDERS 

КранцыWhile mooring, fenders are afloat or suspended between the sides of the mooring vessels protecting them and deck superstructures from impact blows and falling aboard. The energy of the mooring vessels is spent on the fenders deformation and the change in their internal pressure. All known in operation pneumatic fenders containing a set of rubber-cord pneumatic elements with internal tubes are very difficult to assemble and repair, and also have a large weight and a shorter service life. A significant advantage of the fender NVK-3 model produced by our enterprise is reduction of the fender assembly cost, weight reduction, extended service life and accessibility for repair both from the outside and from the inside. 

The Orenburg Separate Subdivision of the “ Orenburgskiye Krantsy — Uralshina” (Orenburg fenders — Uralshina) enterprise resumed the production using conventional technology pneumatic mooring fenders NVK-3, NVK-7, NVK-8. 

КранцыPneumatic fenders are designed to protect fishing, processing and transport vessels while mooring to each other in the high sea (sea force of up to 7) and air temperature from -40 °С to +60 °С

All known in operation pneumatic fenders containing a set of rubber-cord pneumatic elements with internal tubes are very difficult to assemble and repair, and also have a large weight and a shorter service life. 

A significant advantage of the fender NVK-3 model produced by our enterprise is reduction of the fender assembly cost, weight reduction, extended service life and accessibility for repair both from the outside and from the inside. 

The assembly of fenders is carried out on a mandrel, alternating rubber and rubber-cord layers. As a result, a fender has a single cavity, the end parts of which end with metal flanges connected by a tie in the form of a steel strap inside the fender. 

Fenders are also easily mounted: the steel strap is attached to the inner flange bracket by a metal end bracket. Then the strap extends inside the fender to the second flange. 

The lids are fastened by bolts. A nipple is screwed into the lid; the fender is filled with air. 

If the fender cover is damaged, repair can be carried out directly on the vessel or in a stationary workshop, using both hot and cold vulcanization methods, which significantly reduces costs.
