Solvency- Funding key[___][___] The technology and communication capability to find and pick up the ocean debris exists. Additional funding is necessary to tackle the problem.Maritime Reporter, 2012 (“Project to Clean Up North Pacific Garbage Patch,” Tuesday, February 21, 2012 http://www.marinelink.com/news/project-pacific-garbage342616.aspx)
During the past three years, Ocean Voyages Institute’s Project Kaisei, has been successful in studying and documenting what is going on in the Gyre from a scientific perspective. By reviewing ocean current distribution it has accomplished an encompassing survey of clean-up possibilities. In addition, the organisation has built a world renowned group of naval architects, marine engineers and ocean experts that are act as a 'think tank' for designing marine debris collection equipment. The project is currently working on four types of equipment which it believes will enable the four major categories of debris to be addressed.¶ “In 2011 our emphasis is surveying coastal areas and coastal Gyres created by rivers, bays and our other watersheds which are also accumulating debris. There is a great deal of interest in seeing how much of the debris can be found closer to shore,” Crowley said. ¶ While becoming the center for information regarding marine debris collection equipment and heralding the need for global clean-up efforts, Project Kaisei has also been approached by various governments for assistance with designing marine debris collection vessels. “We have been approached by various maritime companies who have told us they have the equipment to accomplish marine debris collections and are working on ways of obtaining corporate and government investment to conduct the clean-up expeditions on a larger scale to test the equipment. ¶ “Ultimately, the assistance of additional funding will enable us to fulfil the potential of providing accurate information on the best and most efficient ways of clean-up. Our future expeditions will be concentrating on continuing science, documentation of the problem, education and research for major clean-up efforts. Obviously, the ability to communicate remains fundamental to our success,” Crowley said. Answers to: Clean Up Fails-Size of the ocean[___][___] Passive technology is scalable. Allows for ocean clean up in all 5 oceans for a limited cost.Slat et al, founder and lead designer The Ocean Cleanup Project, 2014 (Boyan, “A Feasibility Study”, http://www.theoceancleanup.com/fileadmin/media-archive/theoceancleanup/press/downloads/TOC_Feasibility_study_lowres.pdf) The main advantage of passive cleanup is that it is scalable. Using conventional ship-and-net methods, it has been estimated that it would take about 79,000 years to remediate the Great Pacific Garbage Patch (Moore and Philips 2011). And that estimate assumes that vessels cover the entire oceanic area, and that the plastic pollution is spatially static. While the former assumption is perhaps naive or unrealistic, the latter is false. Ship-and net methods are less efficient as the high variability in current directions caused by eddies makes them either repeat their run on the same patch of the sea or to miss some of the plastics. In contrast, our concept uses the natural movement of the water to its advantage. In combination with the circulation period of the North Pacific Subtropical Gyre, the cleanup duration could be drastically reduced (a minimum of 5 years). Due to the passive collection approach, operational expenses can potentially be very low, making the cleanup more cost-effective. Furthermore, converting the extracted plastic into energy, oil or new materials could cover (a large part of) the costs of the execution. Answers to: Clean Up Fails- Ocean Conditions[___][___] Design elements have been tested and will survive in ocean conditions.Slat, founder and lead designer The Ocean Cleanup Project, 2014 (Boyan, “Responding to Critics”, The Ocean Cleanup, http://www.theoceancleanup.com/blog/show/item/responding-to-critics.html) “The problem is that the barriers to gyre cleanup are so massive that the vast majority of the scientific and advocacy community believe it’s a fool’s errand” Boyan: We have now engineered a new floating barrier, that can span the 100 km that is needed to collect almost half the plastic within 10 years. To be sure it stays in one piece, we used a safety factor of 2.5x to 3x, which is much higher than the offshore standard of 1.82x, to be able to accommodate the weakening of the materials due to fatigue. (feasibility study, chapter 3.6). The new design furthermore enables the buoyancy element to move with the waves, which prevents plastic from splashing over or underneath the boom. This has been confirmed with scale model tests. These scale models also showed that this new design can potentially reduce the loads on the tension-carrying element of the barrier by 60%, making our dimensioning even more conservative. [___] The collection platform is based off of technology that is already employed worldwide to withstand ocean conditions.Slat, founder and lead designer The Ocean Cleanup Project, 2014 (Boyan, “Responding to Critics”, The Ocean Cleanup, http://www.theoceancleanup.com/blog/show/item/responding-to-critics.html) My home state of Oregon has been trying to create North America’s first offshore wave energy farm. The first test buoy that was launched, just about 2.5 miles offshore, sank after just a few months. That buoy had a ‘100 year survivability’ rating, and wasn’t just an idea on an Ipad.” Boyan: According to the spokesperson of the wave energy test, the object in question was actually designed to survive only a couple of months. He mentions to Renewable Energy World: “So when people say - Oh there's this device and it sank. How do you expect it to last 20 years or even five years in a real commercial development? It wasn't designed for that,". In The Ocean Cleanup concept, there is also a need for a platform. As some may have noticed, the design of this processing platform has changed from the concept design. We chose for a spar design, which is proven technology, having been used through decades of ocean engineering. Its specific design has been made in collaboration with a Belgian engineering company. (feasibility study, chapter 4.3) The working principles of the system did not change since I presented the concept 1.5 years ago, must be noted.
