Summary:The present invention relates to an riser for preventing interference by using a piezoelectric material for an offshore structure, which prevents collision between risers caused by movement responses of an offshore structure under environmental load by controlling movements of the risers, provides the stability for offshore structures accordingly, and transports produced crude oil in a stable manner. According to the present invention, an interference preventing riser using piezoelectric material comprises: a single-layered or multiple-layered riser body; and a piezoelectric material layer formed in the riser body, which generates piezoelectric effects, wherein the riser body includes a pipe body, an insulating material layer on the outer part of the pipe body, and an insulation coating layer on the outermost part of the riser body, and the piezoelectric material layer is formed between the pipe body and the insulation material layer or between the insulation material layer and the insulation coating layer. 본 발명은 압전효과를 이용하여 라이저의 움직임을 제어하여 환경 하중 하에서 해양구조물의 운동 응답에 의한 라이저 간의 간섭 문제에 의한 라이전 간의 충돌을 방지하고, 이에 따라 해양구조물의 안전성을 제공하고, 생산 원유를 안정적으로 이송시킬 수 있는 압전재료를 이용한 해양구조물의 간섭 방지 라이저에 관한 것이다.본 발명에 따르면, 해양구조물의 라이저에 있어서, 단일 또는 복수의 층으로 이루어지는 라이저 본체; 및 상기 라이저 본체에 구비되어 압전 효과를 발생시키는 압전 재료층;을 포함하는 압전재료를 이용한 해양구조물의 간섭 방지 라이저가 제공된다.
