Smart Fenders A Long Over Due Revolution
PIANC Congress 2014
Presented By Johnny QiuZalda 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 Technology
Conventional Fender System + Positioning Hardware (PSU)
Central Software On PC (CS) To Process Positioning Data
Rendering Fender 3D Model In PC
Further 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

Impact Distribution Based Fender Design
Ship Berthing Contact Velocity Vix -- The initial
movement speed reading of the first
fender system contacted by the ship
during a berthingShip 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
Preemptive Fender Design Optimization
• 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 / 166.8t @ 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
