Patent number: 11248355Abstract: This application relates to a multifunctional recovery apparatus of shore adhesion oils. The multifunctional recovery apparatus of shore adhesion oils removing and recovering oil spilling and sticking at a shore is mounted on a four-wheel vehicle. A skimmer assembly separating oil sticking to the surface of rocks at a shore, and absorbing and recovering an oil spill at the shore is installed at the front of the four-wheel vehicle. The skimmer assembly includes a rotary skimmer having a rotary roller separating oil, and a vacuum suction skimmer suctioning oil floating on a water surface. The rotary skimmer and the vacuum suction skimmer may be selectively or simultaneously used, if necessary.Type: GrantFiled: May 25, 2021Date of Patent: February 15, 2022Assignee: Korea Institute of Ocean Science & TechnologyInventors: Hyuek Jin Choi, Cheon Hong Min, Meang-Ik Cho, Jaewon Oh, Tae Kyeong Yeu, Seong-Soon Kim

Patent number: 10927519Abstract: A recovery system for large-scale spilled oil flowing onto and adhered to a shore is disclosed. The recovery system for large-scale oil flowing onto and adhered to a shore is mounted on an amphibious vehicle that can move on a neritic zone and land. A skimmer assembly is installed in a front of the amphibious vehicle. An oil collection assembly is foldably provided on each of front opposite sides of the amphibious vehicle, thereby easily collecting oil. A recovered oil treatment assembly is mounted on the amphibious vehicle and configured to accommodate the oil recovered by the skimmer assembly therein and to store separated oil by separating water from the accommodated oil.Type: GrantFiled: October 27, 2020Date of Patent: February 23, 2021Assignee: Korea Institute of Ocean Science & TechnologyInventors: Hyuek Jin Choi, Cheon Hong Min, Meang-Ik Cho, Jaewon Oh, Tae Kyeong Yeu

Publication number: 20170145581Abstract: Disclosed is a method of treating the surface of an aluminum substrate, including (a) forming a porous oxide film on the surface of the aluminum substrate and (b) applying a corrosion inhibitor on the surface of the aluminum substrate having the oxide film formed thereon. The method of treating the surface of the aluminum substrate enables the formation of the porous oxide film on the surface of the aluminum substrate through surface treatment so that the applied corrosion inhibitor is partially absorbed into the porous oxide film, thus exhibiting superior corrosion resistance and anti-fouling effects of the metal substrate, compared to conventional surface treatment methods involving coating only with a corrosion inhibitor.Type: ApplicationFiled: May 9, 2016Publication date: May 25, 2017Inventors: Jung-Yeul Jung, Tae-Kyeong Yeu, Sup Hong
