Variable buoyancy platform for aquaculture farming and method of operating the same

A method of operating a variable buoyancy platform comprising:

• providing the variable buoyancy platform, the platform comprising:
• a support frame;
• a plurality of bottom pontoons fixedly mounted to a bottom side of the support frame, each bottom pontoon comprising at least an opening disposed in a bottom portion thereof and at least a bottom pontoon air conduit port disposed in a top portion thereof;
• a plurality of top pontoons immovably and rigidly attached to a top side of the support frame, each top pontoon comprising at least an opening disposed in a bottom portion thereof and at least a top pontoon air conduit port disposed in a top portion thereof;
• a bottom air conduit system connected to the at least a bottom pontoon air conduit port of each bottom pontoon, the bottom air conduit system comprising at least an air supply valve for controlling air flow therethrough and a connector adapted for being connected to a pressurized air supply;
• and,
• at least a top pontoon air valve directly connected to the at least a top pontoon air conduit port of each top pontoon at a first end thereof and directly connected to outside at a second end thereof, the at least a top pontoon air valve for selectively blocking or enabling ingress of ambient air into each top pontoon or egress of air from each top pontoon to the outside;
• when the platform is in a sunken position, connecting the connector to a pressurized air supply and providing pressurized air to the bottom pontoons;
• displacing water in the bottom pontoons until the platform is in a raised position with a top of the support frame being above a water level surrounding the platform;
• closing the at least a pressurized air valve;
• disconnect the connector;
• and,
• releasing water from the top pontoons with the at least a top pontoon air valve being open for enabling ingress of ambient air into the top pontoons.
