Abstract

The present invention provides a method for installing a submarine cable protection module connected to offshore facilities, such as offshore wind turbines, offshore oilfield facilities, and so on, and installing a submarine cable for connecting offshore facilities. The method for installing a submarine cable protection module for connecting offshore facilities and a submarine cable for connecting offshore facilities, according to the present invention, provides a structure in which a submarine cable protected by a bend restrictor, a flexible protection tube, and a centraliser is fixed to a lower support structure of an offshore facility and passes through a metal tube positioned above the sea surface, and the centralizer at the tip of the submarine cable is tightly coupled to a bottom entrance of the metal tube, such that the submarine cable is installed. This structure prevents marine organisms from entering the metal tube, thereby simplifying cable insertion or cable removal operations. Additionally, the present invention allows for cable insertion operations to be conducted with less influence from marine weather conditions, resulting in decreased installation time and costs. Moreover, a ventilation hole is formed through the centralizer connected to the metal tube, thereby enabling the inflow of external air into the metal tube and reducing the internal temperature of the metal tube, thereby preventing a decrease in transmission capacity caused by a rise in temperature of the submarine cable.

Abstract

The present invention relates to an electro-deposition coating composition, a manufacturing method therefor, and an electro-deposition coating method using same, wherein the electro-deposition coating composition has a redox substance incorporated thereinto to suppress bubble formation caused by electrolysis of the solvent during electro-deposition coating and to increase the coating thickness. The present invention provides an electro-deposition coating composition containing a redox material. As an electro-deposition coating colloidal dispersion, the electro-deposition coating composition includes an ionic polymer salt, a solvent, and a redox substance with a lower redox potential than the solvent and ensures that the redox reactions of the redox substance are more predominant than the electrolysis reactions of the solvent when a voltage is applied. By being introduced into the composition, the redox substance with a lower redox potential than the solvent supplies hydrogen ions or electrons and competes with the solvent's electrolysis during the electro-deposition coating process, thereby suppressing the generation of hydrogen and oxygen gases. As a result, the composition minimizes defects caused by bubbles in the coating layer by suppressing bubble generation attributed to the electrolysis of the solvent during electro-deposition coating and thus exhibits the effect of increasing the thickness of the coating layer through higher voltage application or extended voltage time.
