Our latest economic model is v6. Each Eureka IV, our planned production-scale underwater robot, will be able to deliver 12 dry metric tonnes of nodules to the transport ship every 4.3 hours. The same vehicle performs over 5.5 trips per day to deliver an average of 66 metric tons to the transport ship. 100 Eureka IV robots operating in parallel would harvest 6,600 tons per day. No fundamental limit exists on how many underwater robots and transport ships are deployed. We anticipate a volume production per location of around 6.8 million dry tons of nodules annually.
