3 Performance measures
Clasification Society 2024 - Version 9.40
Statutory Documents - IMO Publications and Documents - Circulars - Marine Environment Protection Committee - MEPC.1/Circular.811 – Guidance for Evaluating the 2011 Guidelines for the Control and Management of Ships' Biofouling to Minimize the Transfer of Invasive Aquatic Species – (13 June 2013) - Annex – Guidance for Evaluating the 2011 Guidelines for the Control and Management of Ships' Biofouling to Minimize the Transfer of Invasive Aquatic Species - 3 Performance measures

3 Performance measures

  3.1 Performance measures can help to evaluate whether the 2011 Guidelines for the control and management of ships' biofouling to minimize the transfer of invasive aquatic species are improving biofouling management practice in the maritime industry, and thereby reducing the likelihood of invasive aquatic species being transferred through ships' biofouling. It is not considered feasible at this time to directly measure the environmental benefits of the Guidelines, i.e. to assess whether the Guidelines result in fewer biological invasions by aquatic species as a result of transfer via biofouling of ships.

  3.2 The following types of performance measures could be used to help evaluate the different recommendations in the Guidelines:

  • .1 Awareness and dissemination of the Guidelines – have the Guidelines been disseminated to relevant parties and are they aware of the Guidelines?

  • .2 Impediments to implementation of the Guidelines – are there any omissions and errors with the Guidelines that need to be corrected and/or are appropriate facilities and tools available to effectively implement the Guidelines?

  • .3 Application of the Guidelines – is there evidence of use of the Guidelines?

  • .4 Change in level of biofouling – is there evidence of changes in the level of biofouling from in-water or dry-dock inspections and/or data on the net benefits from managing biofouling?

  • .5 Extent of research and development – what research and technology development, related to the Guidelines, is available?

  3.3 Performance measures for the different components of the Guidelines are outlined in table 1. Each performance measure consists of the criteria being considered, an indicator for the criteria and a goal that the Guidelines are trying to achieve. Note that the "Year(s)" column in table 1 refers to the year following implementation when information is likely to be available for the relevant performance measure. Table 2 outlines a questionnaire that could be used to provide a uniform, but voluntary, approach to collecting information.

  3.4 In collecting information for performance measures it is useful to collect information not only on progress towards the specified goal but also information on why a particular goal is or is not being achieved. This would help the Sub-Committee to determine if actions, such as modifying the Guidelines, are required.

  3.5 The high level goal across all performance measures is to see an increase in the uptake of the recommendations of the Guidelines over time.
