Environmental challenge

Installations: We have installed 71 modules and scale test versions of our “Pisa Reef” concept, as it has developed over 15 generations and 20 years since 1996, mostly with our own funds. By far the largest number (37 of the new Pisa Reef model) were produced during the REEFS project during 2014-2016 (see below). This has given us an extremely detailed proof of concept, coupled with a very strong history of practical implementation and operations as well as design and engineering.
