... uma vez que o tambor havia sido instalado de cabeça para baixo na sua posição seria cheia de ar que veio em mangueiras dos compressores no convés da barca ... os tambores eram lentos a se encher de água, mas fácil e rápido para preencher com ar comprimido ...

...Marcelo had brought 180 plastic drums of 55 gls capacity (in the last stage of the operation we needed 50 more)...part of these drums we now dumped into the water and flooded by swimmers on the surface...after a drum was full enough to slowly sink, a diver would take over and guide it to one of the six heavy straps which had been tied around the boat...there was also a network of other lines tied between the main straps...
...once the drum had been attached upside down in its position it would be filled with air which came in hoses from the compressors on deck of the barge...the drums were slow to fill with water, but easy and fast to fill with compressed air... — em Ilha dos Meros, Brazil.
