Risk Assessment in Ballast Water Management - Global Maritime Transport and Ballast Water Management: Issues and Solutions - page 136

Table 1 RA initiatives worldwide prior to the adoption of the G7 Guidelines

Data expression
approach RA initiative Goals RA approach End-point

Australia (AQIS 1994 ) Estimate costs of toxic

dinofl agellate introductions
in Australian waters

Species based tolerance, volume of ballast
discharged and bloom dynamics

Quantitative Estimate economic impact

of toxic dinofl agellates on
aquaculture, tourism, etc.
(hazard assessment)

Germany (Gollasch 1996 ) Risk identifi cation for

species invasions in German
coastal waters

Environmental matching between donor
and recipient localities

Qualitative Species establishment

potential assessment

Australian DSS a (Hayes
and Hewitt 1998 , 2000 )

Identify low risk routes,
vessels and tanks

Models four steps in the bio-invasion
process: donor port infection, vessel
infection, journey survival and survival in
the recipient port

Quantitative Target species life cycle

completion in recipient port

Nordic countries (Gollasch
and Leppäkoski 1999 )

Risk identifi cation for
species invasions in Nordic
ports and coastal waters

Environmental matching between donor
and recipient localities

Qualitative Species establishment

potential assessment

DNV - EMBLA (Behrens
et al. 2002 , Endresen et al.
2004 )

Identify low risk routes,
vessels and tanks

Bioinvasion model based upon: donor port
infection, vessel infection, journey
survival and survival in recipient port

Quantitative Target species life cycle

completion in recipient port

GloBallast RA (e.g., Awad
et al. 2004 )

Enhance awareness and
recommendations on BWM
strategies

Environmental matching between donor
and recipient localities, weighted by target
species presence in the donor location and
inoculation factors

Semi- quantitative Identify and rank high and

low risk ports

Slovenia 1 (David 2007 ) Risk identifi cation for

species invasions in the
Slovenian Sea, enhance
awareness and recommend
BWM strategies

Environmental matching between donor
and recipient localities and identifi cation
of potentially harmful species in ballast
water

Quantitative and
qualitative

Identify and rank high and
low risk donor ports
