Smart Fenders A Long Over Due Revolution PIANC Congress 2014 Presented By Johnny Qiu Zalda Technology Corporation
Fendering Since 1950s 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 1950s – 1980s 30 years of development process centered around compression rate Square – Trapezoidal – Arch – Element Cylindrical – Cell – Cone – Stacked Cone Technical Stalemate Since 1980s Frontier technology of the 1950s Lack of significant technical development since 1980s 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 TechnologyConventional Fender System + Positioning Hardware (PSU)Central Software On PC (CS) To Process Positioning DataRendering Fender 3D Model In PCFurther Data Analysis To Generate Warnings and Alarms PSU are mounted on predetermined locations on fender frontal structure CS generates dynamic 3D 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 – Reducing Costs Reducing Fender Related Costs Address The Causes Of Fender Related Costs
Smart Fenders – Transparent Fendering
Smart Fenders – Total Understanding, Better Design New Approach To Fender DesignUnveil Mysteries Of Fender Design Impact Distribution Graph & Historical Data Replay Easily Answer Necessities Questions Definitively Answer Cause Questions Impact Distribution Based Fender Design Fender System Reconfiguration Fender Asset Redistribution Follow The Trends To See The Future
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 design capacity, berthing energy amplitude alarm will be triggered Smart Fender will trigger a fender design energy capacity warning if : --- Measured ship berthing energy frequently approaches design value --- Fender compression frequently approaches rated fender deflection Smart Fenders Explained – Energy Warnings & Alarms Whereas W: ship loaded mass V: MEASURED ship berthing configuration velocity Vix Ce: ship eccentric coefficient Cm: ship mass coefficient Cs: ship softness coefficient 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 Fender Side Motion (Y Axis ) Historical Data: Easily determining if a fender system needs shear chain on one side, both sides, or none at all. Fender Compression Motion (X Axis) Historcal Data Berthing Impact Distribution is uneven along the berth. Therefore it is clearly unreasonable to distribute fender asset evenly. Optimize Fender Components Using Data Approach Fender Elastomer Shear Chain / Weight Chain / Tension Chain Fender Frontal Structure ETC Prevent Fender System Permanent Damage Prevent Damage to Ship and Dock Structures Due to Insufficient Fender Design.
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
First Major Smart Fender Project In The World 12 Fender System Project In East Asia Installed On March, 2011 Smart Fender System On 8 Main Fender Systems And 2 Auxiliary Fender Systems Each Main Fender System Has Two Off I 1000x2000l S2 ( ER= 76.8tm / 57.5% ) And One Off 3150x2750x320 Fender Panel, With No Restraining Devices On Each Fender Panel, Four PSU Modules, One LIS Module, And One Auxiliary Battery Module Were Installed Using Internal Installation Scheme A Generic PC Workstation ( Intel I 3 / 1GB / 500 GB / Win 7 ) As Smart Fender System Central Station Smart Fenders – Case Study YHL 1103 General Information
14 Berthing Speed Alarms Since Mar Fender Lateral Movement Alarms Since Mar Low Impact Alarms Since Sept Angle Alarms Since June, 2011 Fender Design Weakness Warnings On Insufficient Fender Energy Capacity And Insufficient Restraints. Berthing Practice Change Recommended and Adopted. Preemptive Design Optimization Performed With I 1000x2000 H2.
