Manufactured concrete artificial reef modules, like construction debris, only require a 250 foot setback from live reef. Manufactured modules have much less volume than debris or a ship. They only need to be transported once – from the manufacturing site to the barge – and a barge load only takes about eight 18 wheel flat-bed truck loads.
They do require “pin-point” placement by crane with a diver instead of just pushing the materials off the barge.
Reef Balls have not been widely used in the ocean off southeast Florida and we are not pursuing incorporating them into our projects.
Reef Pyramids are widely used in the Gulf of Mexico, and we may consider them for future projects. But a deployment of reef pyramids looks like…a bunch of pyramids, not a natural reef. We are always looking for “perfect” solutions.
