exchange in the North Seaexchange in the North Sea
• 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

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

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
• 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
