Smart Fenders A Long Over Due Revolution PIANC Congress 2014 Presented By Johnny Qiu Zalda Technology Corporation
Fendering Since 1950 s Invention of Engineered Fenders • Definition of fender – A means for controlled release of berthing kinetic energy • Makeshift solutions prior to engineered fenders • Invention of engineered fenders Innovations 1950 s – 1980 s • 30 years of development process centered around compression rate • Square – Trapezoidal – Arch – Element • Cylindrical – Cell – Cone – Stacked Cone Technical Stalemate Since 1980 s • Frontier technology of the 1950 s • Lack of significant technical development since 1980 s • Technical Stalemate, lack of data, single purpose, generic design and products
Smart Fenders – The Vision Exploration of Fender Potentials • Location Advantage – Unique Waterfront Location • Carrier of Ship - Dock Interaction • Basic Fender Functions – Better Protecting Ships and Docks Directions of Smart Fender Development • Reinvent An Age Old Product with New Technologies • Expanded & Diversified Functions and Possibilities of Individuation • Generate Values with Services and Information A Long Over Due Revolution THE FUTURE IS FINALLY HERE !
How To Build Smart Fenders Inertial Guidance & Multi Layer Positioning Technology Conventional Fender System + Positioning Hardware (PSU) Central Software On PC (CS) To Process Positioning Data Rendering Fender 3 D Model In PC Further Data Analysis To Generate Warnings and Alarms PSU are mounted on predetermined locations on fender frontal structure CS generates dynamic 3 D model of the fender system along with its motion characteristics, based on position and heading of PSU With motion data, CS generates fender related warnings, alarms, and analysis using fender engineering and design principles

Smart Fenders Explained – Energy Warnings & Alarms Ship Berthing Contact Velocity Vix -- The initial movement speed reading of the first fender system contacted by the ship during a berthing Ship Berthing Impact Kinetic Energy Amplitude Es is calculated based on Measured Vix and known ship and dock characteristics If calculated ship berthing kinetic energy exceeds berth fender system Whereas design capacity, berthing energy amplitude alarm will be triggered n W: ship loaded mass n V: MEASURED ship berthing configuration velocity Vix Smart Fender will trigger a fender design energy capacity warning if : n Ce: ship eccentric coefficient --- Measured ship berthing energy frequently approaches design value n Cm: ship mass coefficient n Cs: ship softness coefficient --- Fender compression frequently approaches rated fender deflection n Cc: berth configuration factor
Smart Fenders Explained – Reaction & Structural Impact Alarm BIM monitors compression displacements of all fender elastomers and interpolates their real time reaction forces using their C-RE curve Instantaneous Berthing Impact Load RT = total fender reaction force of all fender elastomers compressed by the berthing ship If RT reaches or frequently approaches preset berth structural limit, Smart Fender will trigger Berth Structural Load Alarm
Smart Fenders Explained – Data Based Fender Design Optimize Fender Components Using Data Approach • Fender Elastomer • Shear Chain / Weight Chain / Tension Chain • Fender Frontal Structure • ETC Preemptive Fender Design Optimization Fender Side Motion (YMotion Axis ) Historical Data: Data： Compression (X Axis) Historcal • Prevent Fender System Permanent Damage Easily determining if a fenderissystem chain Berthing Impact Distribution unevenneeds alongshear the berth. • Prevent Damage to Ship and Dock Structures Due to on one side, both sides, or none at all. Therefore it is clearly unreasonable to distribute fender Insufficient Fender Design. asset evenly.
Smart Fenders Explained – Imminent Failure Warning By tracking long term trend of fender static posture and general compression range, Smart Fender can predict fender failure when fender deterioration reaches critical level. This allows preemptive preventive maintenance to be preformed at chosen time frame, to avoid costly adverse influence to terminal operation due to unexpected fender maintenance
