도 2와 도 3에는 종래예에 따른 해양구조물용 전극이 도시되어 있고, 도 4에는 종래예에 따른 해양구조물용 기준전극이 도시되어 있는 바, 이를 참조하여 해양구조물의 부식방지용 전극과 기준전극을 간략히 설명하기로 한다. 한편, 도 2와 도 3에 도시된 전극은 각각 선형과 타원형의 형태로 되어 있으며, 도 4의 기준전극과 대체로 유사한 구조를 갖고 있다. 그리고, 도면상에서는 선체(110)의 윗면이 해수에 접촉되거나 잠기는 면이 된다.2 and 3 show an electrode for a marine structure according to the prior art, and Figure 4 shows a reference electrode for an offshore structure according to the prior art. It will be briefly described. Meanwhile, the electrodes shown in FIGS. 2 and 3 are linear and elliptical, respectively, and have a structure substantially similar to that of the reference electrode of FIG. 4. In addition, in the figure, the upper surface of the hull 110 is in contact with the sea water or the surface is locked.

종래의 해양구조물에 설치된 부식방지용 전극이나 기준전극은, 수리가 필요한 경우 도킹작업을 통해 고정된 부분을 해체하고 손상된 부분을 교환할 수 있었다. 즉, 전극이나 기준전극의 몸체부(120,121,122)는 선체(110)를 통과하여 이 선체(110)의 안쪽으로 뻗는 전극용 전선(130)과 연결되도록 되어 있으며, 이 전극용 전선(130)은 케이블 글랜드(142,143,144;cable gland)에 의해 밀폐용 플랜지나 개스킷 등을 포함하는 코퍼댐(cofferdam)구조물(140)내에 밀폐상태로 수용된다. 이와 같은 구조를 가진 몸체부(120,121,122)를 새로운 것으로 교환하거나 손상된 부분을 수리할 필요가 있을 때, 해양구조물이 해수에 잠겨 있는 상태에서는 교환시에 고압의 해수가 선체(110)의 내부로 침입할 우려가 있게 된다.The corrosion preventing electrode or the reference electrode installed in the conventional offshore structure, when repair is required, the docking work can be dismantled and the damaged parts can be replaced. That is, the body parts 120, 121, 122 of the electrode or the reference electrode are connected to the electrode wire 130 extending through the hull 110 and extending into the hull 110, and the electrode wire 130 is a cable.
