액체이산화탄소운반선 저장 탱크 특허분석 및 IP 창출 = Patent Analysis and IP Creation of Liquid Carbon Dioxide Carrier Storage Tank

다국어 초록 (Multilingual Abstract)

The development of liquid CO storage tanks and liquid CO handling technology 2 2 are key for liquid CO2 carriers, and it is necessary to extract core patents of competitors that may lead to patent disputes in the future, establish response strategies, and strengthen the IP portfolio by creating new IPs. As a result of patent analysis for this purpose, patent applications and technology development are being led by the three large domestic shipbuilding companies(Hyundai, Samsung, and Hanwha) and the large Japanese shipbuilding company(MHI), and the handling of liquid CO2 storage tanks and liquid CO2 (prevention of dry ice formation) Technology-related patent applications and technology development are actively taking place, so there may be concerns about patent infringement. Currently, It has been confirmed that there are no core patents that are likely to cause patent disputes in the future. However, the technology concept in question lacks patentability as it is a combination of known technologies, so the creation of new IP is necessary to establish exclusive rights. Accordingly, through this project, four new IP creations and patent applications based on competitors' patents were completed. ① Technology to prevent the release of dry ice during unloading using filters, ② Technology to prevent the creation of dry ice in the unloading piping during unloading, ③ BOG reliquefaction technology to respond to CO2 emission ban regulations, and ④ Technology that can utilize BOG within ships.
