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
