In-Depth Information
Expertise
At best a PSC offi cer should be able to use the organism detection method(s) with
some special training, but without a need for academic education in biology or
chemistry.
Portability
Portable sample analysis equipment, which may be carried onboard a vessel by one
person, is benefi cial because the analysis can be undertaken “on the spot”, i.e., on
the vessel. Alternatively, the samples may be taken from the vessel to a laboratory
or to a van on the pier equipped with necessary sample analysis equipment.
Costs
The methods selected should not be too expensive (capital costs) and should also be
cost effective regarding running costs (e.g. operating costs, consumables). However,
the accuracy and precision of methods is of prime importance. In general, an expen-
sive, but prompt and accurate organism detection technology is to be preferred to a
cheaper not as accurate system.
Recommended Technologies to Proof Compliance
with the D-1 Standard
Sample analysis tools to proof compliance with the D-1 standard, such as tracers of
human activities or a salinity meter are available and were already described above.
Recommended Technologies to Proof Compliance
with the D-2 Standard
It is important to note that a ballast water sample analysis may be undertaken for all
three groups of organisms of the D-2 standard. King and Tamburri ( 2010 ) as well as
Gollasch and David ( 2010b ) concluded that it will be very diffi cult to promptly
assess whether or not the ballast water of a vessel meets all limits of all organism
groups in the D-2 standard. However, should one organism group already show to
be above the required concentration of viable organisms, non-compliance is indi-
cated and the other two organism groups may not need to be tested.
