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

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

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

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
