Project Information

• Duration: 01/2009 – 06/2010

• Funding: European Space Agency (ESA)– Programme: ESA DUE Innovator II– Testing the applicability of remote sensing satellite data in new

applications

• Goal: Investigation of the opportunity for remote sensing satellite data to contribute to the risk assessment of Ballast Water exchange

• Development and Implementation of the BallastWater Risk Index concept: Brockmann Consult

• End User of the service: BSH



Ballast Water Exchange Risk Index• Recommendations of the IMO Ballast Water Convention

for ballast water exchange areas– Distance > 50nm– Depth > 200m– No turbid water– No outbreaks / HABs– Currents away from land– No sensitive aquatic areas– Closest to ship routes

• Utilisation of remote sensing data where available and suitable– Chlorophyll concentration– Turbidity– Suspended matter– Temperature

Transparency



Assumptions Risk Index Model

• Highly turbid waters high risk• Near the coast high risk• Near protected areas high risk• Shallow waters high risk• Drift to the coast high risk• High chlorophyll concentration high

risk• High suspended matter high risk• High CHL / turbidity at drift position high risk • Low difference between source and destination

area (Salinity, Temperature) high risk



Product• Product: Risk Index Map

– High values indicating potential negative impact of ballast water exchange

• Model Principles– Standardisation of input parameters– Tuning parameters (weighting factors)– Easy integration of additional parameters

• Final Ballast Water Exchange Risk Index is composed of specific thematic risk indices

ESA UCM Ballast Water Risk * Hamburg * 25.01.2011Ballast Water * North Sea Exemption Group * 17.06.2010

Average Risk Index: Idea

• Detection of stable high or low risk index regions• Independent of source of the ballast water• Calculation of daily Risk Indices for 2006 - 2008

– Exchange Risk Index – Drift Risk Index 1095 daily products

• Averaging over certain time periods– Monthly– Seasonal– Semi-annual– Yearly

• Calculation of standard deviation for the assessment of the stability of certain areas



Process I: Daily Risk Index

Process II: Averaging

Products and Use Cases

• Dynamic Risk Index– Use Case: Ship is requesting permission for ballast water

exchange from BSH– Service Delivery: Generation of Risk Index via the web

service• Input: Date, Salinity, Temperature, Currents, Uptake/Exchange, …• Output: Risk Index Map

– Update Frequency: on demand processing

• Average Risk Index– Use Case: Assessment of the general risk situation and

identification of potential exchange / no exchange areas – Service Delivery: pre-calculated maps are available via

the web service– Update Frequency: static



Web Application Dynamic Risk Index



Web Application Averag Risk Index



Support for the Exemption Group

BROCKMANN CONSULT



Cooperation• Close Cooperation with BSH

– Product definition– Model implementation

• Presentation to International Bodies– OSPAR EIHA– HELCOM MARITIME– ICES/IOC/IMO Working Group on Ballast Water and other Ship

Vectors

• Relationship to Interreg Project Ballast Water Opportunities– Participation in different meetings– Presentation of the Risk Index Approach– Exchange and knowledge sharing with the North Sea

Exchange and Exemption Group– Adaptation of products according to requirements of the

North Sea Group

BROCKMANN CONSULT



Summary

• Development of a risk index model for ballast water exchange

• Two Risk Index Products– Dynamic Risk Index – Average Risk Index

• Two Use Cases– Calculation of the ship dependent risk for ballast water

exchange– Demonstration of high/low risk areas

• Implementation as web service

• Close cooperation with BSH and the Interreg project Ballast Water Opportunities
