It could be sunk in water deep enough for techies to explore the base with trimix, whilst air divers explored underneath the platform, cave divers explored the cabins and corridors, and basic open water lessons took place at 6 metres on the helicopter pad. Elsewhere in the world old ships and other junk are regularly disposed of in convenient diving locations. Local businesses are actively seeking opportunities to create more dive sites for a growing tourist industry. Off Florida there are hundreds of wrecks in the artificial reef programme and it isn't just divers who benefit, anglers have a great time fishing on them. In some parts of the world artificial reefs have been bad for the fish stocks.
Fish enter the new reef from the surrounding area.
If these are then caught and removed from the scene, more will follow, to the point where an over-fished artificial reef acts as a siphon of fish from the surrounding area. This effect has lead to artificial reef projects actually being banned in the Philippines. But the problem is really uncontrolled over-fishing, not the artificial reefs. In Britain we can see purpose sunk wrecks happening to some extent at inland dive sites. Boats, helicopters, buses, aeroplanes, armoured vehicles and cars have all been deliberately sunk by site owners to provide something for divers to play on.
