Pianc Wg211 - Guidelines For The Design Of Fender Systems

Marine fenders are a critical component in maritime infrastructure, absorbingthe energy of vessels during berthing and while moored. Therefore, setting up of MarCom Working Group 211 "Update of WG 33 – Guidelines for the design of fender systems" has been set up to provide concise and clear design guidance for fender systems, in alignment with current practice, together with updated guidance in relation to fender materials, performance, testing, durability and maintenance. Objective of the WG211 is to prepare a general update of WG33, including: 1. Update the basis of design and design guidance in relation to: • alignment with current practice including reliability design methods• latest simulation software for evaluation of fender /vessel interaction• recent vessel trends including increases in vessel sizes, developments in hull shapes and the implications for fender engagement• vertical and horizontal forces on fenders• hull pressures• outline consideration of special issues applying to wheel fenders and foam filled fenders2. Review recent research by fender manufacturers and update guidance in relation to durability and performance, including: • fender materials composition and influence on performance factors• fender durability and causes of failure• impact of aging on fender performance and reactions3. Review the WG33 guidance in relation to testing procedures for fender materials and fender performance, with specific reference to: • representative scope of testing• consistency of test procedures and compliance in testing facilities• representative quality and quantity of samples to be tested, • independence of testing and verification of fender materials and performance4. Clarify that PIANC is not a fender certifying body and cannot endorse certification of compliance by third parties using the guidelines5. Provide guidance on design of other fender system components including facing panels, chains and fixings6. Provide guidance on durability
