Performance test and evaluation description

  3.17 A full description of the onboard tests and evaluations to be undertaken should be provided. When available standard methods for the collection, handling (including concentration), storage, and analysis of samples should be applied. These methods should be clearly referenced and described in test plans and in reports. This includes methods for detecting, concentrating, enumerating, and identifying organisms and for determining viability. When non-standard methods are used they should be validated, documented and reported. A description of the experimental design and sampling procedure should be provided.

  3.18 The Programme should evaluate:

  • .1 the biological efficacy of the installed prototype ballast water treatment technology;

  • .2 the operational performance which should include, but not be limited to:

    • unplanned maintenance and manning requirements

    • operational data relative to manufacturer's specification

    • consideration of the environmental conditions identified in section 3.9.2;

  • .3 the effects upon the ship's systems and structure; and

  • .4 any other characteristics identified by the participants or the Administration.

  3.19 Experimental Design and Protocols should include:

  • .1 a general description of the experimental test including the experimental hypotheses being tested and methods for the determination of biological efficacy and operational performance. The Programme Application should identify the test locations, source waters, and relevant environmental water conditions, to the extent possible. The overall study plan should take full advantage of the range of locations provided by the vessel’s operations, to the extent practicable;

  • .2 a detailed description for each of the experiments including:

    • .1 ballast water sample collection for each treatment and control, identification and number of replicate tanks, ballast water samples and time points encompassed in the test;

    • .2 description of test runs: replicate tests (tests at same location and environmental conditions) and comparative tests (tests at different locations or environmental conditions). Description of how the efficacy of the treatment process should be evaluated; include a description of how the efficacy should be quantified, as well as a description of the comparison of biological efficacies;

    • .3 the plan should address statistical analysis (including power analysis) and data confidence issues. Fully describe the intended statistical tests, use of controls, and replicates for each experiment; and

    • .4 how the experiment accounts for the range of seasons, organic matter content, turbidity, pH, salinity, etc. likely to be encountered in operation and, to the extent possible, describe the range of these variables;

  • .3 the experimental design should address the operation of the ship’s systems whose arrangements (e.g., cross connections) have the potential to confound the resulting data.
