Marine Rubber Fender System

Marine Rubber Fenders are critical for the energy absorption of a berthing vessel into the berth structure. A single tanker can be over 500,000 tons so safe energy absorption in worst case scenarios is paramount. The marine fenders primary job is to protect the berthing structure without damaging the vessel hull for all potential vessel types, sizes and approach scenarios. ESC offers a full range of fender options to compliment its marine steel piling products.

Design, Manufacture & Testing

Preliminary Design & Budgeting

ESC can complete a preliminary assessment and design of the most appropriate fender system to allow budgeting and estimation for projects. ESC can complete this even with a limited information set.

Marine Fender System Detailed Design

ESC has developed software that assist in calculating berthing energies for the project’s complete vessel range which are then used to specify the optimal fender configuration which includes  rubber fender selection, frontal panel sizing and location, chain and anchor design and if appropriate cathodic protection design. These calculation is conforming to BS 6349: Part 4, PIANC guidelines and other standards.  Full manufacturing and layout drawings are produced to enable high quality production and comprehensive detailing for installation on site.

Manufacturing

ESC’s fender product line is comprehensive, with over 50 profiles and various rubber grades (low reaction to super high reaction force) to select from. The frontal pad fabrication facility (complete with blasting and painting) is in close proximity to the fender facility which makes factory visits and ex-mill logistics more convenient and efficient. Components such as chains and anchors are produced by pre-qualified manufacturers also in close proximity to the facilities.

Marine Fender Systems
Quality Assurance & Testing

Marine Fender Rubber is an engineered material that exhibits optimal properties in terms of cost, energy absorption, wear resistance, UV resistance and more. An engineered mixture of additives is used to improve the overall mechanical and wear properties of the material. The rubber utilised comes from the highest quality sources and is inspected and testing in accordance with the ISO 9001 Quality Management System. Some parameters tested are: tensile strength, elongation at break, compression set, hardness, density, seawater resistance, tear resistance, ozone resistance, abrasion resistant, bond strength and ageing.
