HI-TECH is the only Company to have manufactured the Largest Pneumatic Fender in INDIA.

The conventional Solid Fenders and Foam Filled Fenders rely on the elasticity of the rubber / foam to absorb the kinetic energy of the ship. The elasticity and the other properties of rubber / foam being are not constant, in marine environment, due to ageing. This causes a reduction in the Energy Absorption capacity and increase in the Reaction Forces.

Alternatively, the HI-TECH Pneumatic Fender uses the elasticity of the compressed air. The properties of compressed air remains constant throughout the working life of the Fender, giving consistent values of Energy Absorption and Reaction Forces.

The compressed air absorbs a greater amount of kinetic energy and causes its distribution over the surface of the Fender, thus exerting a very low surface pressure & thereby producing a lesser and a gradual reaction. This provides a longer working life for the Fender.

HI-TECH Pneumatic Fenders are widely used for ship-to-ship operations. Applications include :

  • Tanker lightering & other transfer operations, such as coal, ore, or grain

  • Bunkering operations & Naval Applications

  • Crane-Ships, Drill-Ships & Pipe-laying vessels

  • Lay-up of vessels (side by side mooring)

  • Due to buoyancy & lighe weight these fenders are very easy to install & handle even during the high tidal ranges of the jetty and thus proves cost-effective in Jetty construction.

  • Very efficient in taking up oblique loads and in resisting shearing forces during inclined berthing. This is achieved even without any additional Factor Safety in designing.

  • The unique feature of this fender type is the Safety Valve, which provides a check to the maximum level of pressure that the fender can withstand, and hence is more secured in case of subjection to excess loads.

  • HI-TECH Pneumatic Fenders due to their inherent property of High Energy Absorption coupled with Lower Reaction Forces allows an economical design for constructing the Jetty.

  • The floating tendency of the HI-TECH Pneumatic Fender, provides a phenomenal advantage over the other kinds, as these fenders can be put to us for mid-sea ship-to-ship cargo transfer. This proves a boon where ports lack facilities of large jetties for berthing large of additional Vessels.

The HI-TECH Pneumatic Fenders are also utilized for ship-to-dock and ship-to-structure applications, particularly in exposed locations and areas where its superior abrasion resistance is an important factor :

  • Exposed jetties, berths & Offshore applications

  • Rough berthing surfaces such as sheet pile walls, rusted steel, rough stone and concrete

  • Construction operations, Shipyards & inside dry-docks

HI-TECH has INDIA’s largest size Press for Load Deflection & Energy Absorption Tests.

This Press can handle job sizes upto 7.5mtr (w)x 12mtr(I) x 5mtr. (h). This enables to provide a total Quality Assurance of Fenders, of all types & sizes, by testing them at their maximum load capacity.

HI-TECH has now extended its services to Repairs of damaged Fenders.

The outstanding advantage of this facility lies in its ability to revive life in such fenders and thereby providing an extended working life to the Fendering system and a substantial cost-effectiveness for any project. Nevertheless, these repairs are Quality Assured by the performance test carried out on this Press and other testing facilities.
