Abstract

Because offshore plant industry needs to design, deploy and operate much of equipment especially, the latest trend shows the installation of production facilities is augmented in the subsea. The installed facilities are very difficult to be repaired or changed because they are located in the subsea. For solving these problems, both the directly related information of the production like the optimal number, position and depth of wells and the distribution for effective operation and safety of equipment of subsea should be considered at the preliminary stage of FEED (Front End Engineering Design). The marine exploration is introduced in this paper for providing the fundamental technology to answer the questions related to above considering points. First, some kinds of the offshore plant facilities are enumerated and aims of marine exploration for the offshore oil/gas development are summarized. In addition to it, the main roles of marine survey, in the step of designing and installing offshore oil-gas plant, development are briefly listed. And then foreign examples are shown to help the reader's understand. This paper is hoped to be helpful for understanding the marine exploration that can be applied to offshore oil/gas plant and to be contributed to developing the domestic techniques in this field for the future.

해양 오일-가스 개발을 위한 플랜트 산업은 많은 장비들을 설계 및 배치하고 운영해야 하는 산업이며, 최근 동향을 보면 생산설비가 해저면(Subsea)쪽으로 증대되고 있다. 해양이라는 특성상 한번 설치되면 변경하기가 용이하지가 않으므로 기본 설계단계에서부터 적절한 시추정 개수, 위치 및 심도, 생산관 직경, 생산 시 관막힘 또는 손상 등의 생산 및 운영과 직접 관련된 정보뿐 아니라 해저에 설치되는 장비들의 안정성과 효과적인 생산운영을 위한 배치에 대한 고려가 필요하다. 이러한 정보들을 근본적으로 제공하기 위한 기법으로 해양탐사를 본 해설에서 다루고자 한다. 먼저 해양 오일-가스 개발을 위한 플랜트장비들을 요약하고, 오일-가스 해양플랜트 설계 및 설치 단계에서 해양탐사가 담당하는 역할을 요약하였다. 그리고 해외사례를 통하여 독자의 이해도를 높이고자 하였다. 해양 오일-가스 플랜트에 적용될 수 있는 해양탐사기법에 대한 이해와 향후 이 분야에 필요한 국내 해양탐사기술 개발에 도움이 되고자 한다.
