In accordance with OSPAR Convention rules, the ships were cleaned of all environmentally hazardous materials or dangerous for divers. This preparation was done with the help of Canadian Artificial Reef Trading Consultant (CARC), that accounts for more than 23 Navy vessels deliberate immersions around the world.
Four warships that played a key role in the history of the Portuguese Navy sunk one by one a few dozen metres from each other, creating an authentic and freely accessible underwater theme park along the coast of Portimão.
This is the biggest artificial reef in Europe, where a fleet that once formed a whole armada will be transformed into a sanctuary brimming with marine life, with a complementary visitor centre on dry land, at the Portimão Museum.
