IWMA Scaling Project 2009
The IWMA Scaling project was successfully finished and the results were presented at IMO FP meeting 2009. The final report was published and you may request a copy by sending an email to info [at] iwma.net. The paper summarizes and suggests with respect to machinery spaces that we allow doubling the enclosure volume based on the tested volume if the duration of the water supply is increased to 45 minutes.
