There are many critical elements in relation to the design, selection and installation of BWTS. The process is a quadric-modal one which starts with the selection and the design study, followed by detailed study and installation. However, we will confront a lot of challenges in the process. What is critical is what lies below the iceberg. Had the Convention been validated tomorrow, we would need to do 40-50 retrofits every day until the end of 2017. Having that number in mind, it seems that we should not over emphasize the selection process. Unfortunately, we don't have feedback from BWTS already installed. We are dealing with a case of public pressure putting the regulations ahead of technology. We can apply advanced selection techniques like fuzzy- logic or multi-criteria decision analysis, or simpler statistical grading of  questions which can be grouped  related to technical, health and safety , financial, operation, installation and maintenance considerations. The one million question is '' are we going to have the time to go through this grading and selection process?'' The installation questions we have is where to place the system, how to integrate it with  the remaining machinery and what to do. We have to forget...
