Cordava 

Cleaning up the Great Pacific Garbage Patch

Briggs is developing a ship designed to remove the rubbish in the Great Pacific Garbage Patch and other oceanic gyres.

The Aceson program has budgeted for 2 ships to be built under this Cordava is the name given to the program to develop a ship design to remove rubbish from the Great Pacific Garbage Patch and other concentrations of litter in the oceans. This capital may allow a third ship, with the finance to last until the Aceson Corporate bonds are repaid and the Shaneen airliner sales can fund the completion of more ships for the effort.

Essentially Cordava filters fine rubbish debris and particles from the ocean, retuning any marine life to the water. The concept will be developed with Aceson funding into an operational vessel. The design took a year to develop. At this stage two Cordava ships will be built with the Aceson budget: operational costs of the ships prohibit the construction of further ships until the Aceson Corporate Bonds are repaid. The first Cordava ship will serve as a technology test-bed until the costs are established: the second and potentially third ships will be designed from lessons learnt from the first Cordava.

The variable for more ships - despite a $705 million budget - will be the operational costs of the ships. Although the ship cost will only be around $150 million each and be available within 2-3 years, depending on the speed of the sale of Aceson Corporate Bonds. The operational costs may exceed $40,000 per day from fuel and maintenance; ships fuel consumption ranges from 120 to 140 tonnes of heavy fuel oil every day. Commitment to a third ship under the Aceson budget will not be made until more accurate financial data provides the go-ahead.

The function of the Cordava ships is simple, to get rubbish out of the ocean at high rates. Using the engineering guidelines established by the Cordava design effort, by processing 3 megalitres of water per second, a square kilometre 150 feet deep could be processed every hour.

Even at such high rates the size of the Great Pacific Garbage Patch makes it an enduring process until more ships are built. With two ships and the debris field at the present size it would take 77 years to process the litter from the Great Pacific Garbage Patch: 10 ships would take 15 years. This excludes the fact more rubbish is still flowing out to sea, the dated statistics for the Great Pacific Garbage Patch, and, unfortunately, there is more rubbish in debris fields in other oceanic gyres, around the world.

 The reduction of shore based litter via ongoing services of Oceaneleen, plus the possibility more ships can be built and operated with either lower than expected operating costs, assistance from governments and the Shaneen based funding provide strength to Cordava services, which begin the process of cleaning up the mess we have made from over a century of unchecked littering.

The advantage of Cordava is it builds and proves the technology, a situation allowing governments to participate financially, since it is unlikely any government would back the development of these ships at its own cost due to the costs involved.
