최근 우리나라의 해양플랜트 산업 성장과 관련하여 이 같은 산업에 종사하는 필수 인력 가운데 각종 수중작업을 수행하는 고도의 기술을 가진 인적 자원의 확보가 필수적이다. 따라서 본 연구는 우리나라의 산업잠수 종사자 교육 및 훈련실태 그리고 자격요건 등을 조사하고, 선진국에서의 Offshore Diver 종사자를 위한 교육 및 훈련과정과 자격인증 제도 현황을 조사 비교하여 향후 우리나라의 Offshore Diver 인력양성 및 교육의 제반여건을 마련하는데 기초 자료를 제공하기 위한 목적으로 수행하였다.

In order to inspect the existing or newly constructed ship's hull, a professional diver directly inspects the ship's bottom of the water. However, since it is a work done by people, there are many dangers such as human casualties and crashes. To solve this problem, it is necessary to develop underwater drones for ship inspection for visual inspection. The technology applied to underwater drones, the use and manufacturing process of each component, and the method of manufacture such as firmware development were described, and the difference was compared by measuring the drone's own driving ability and driving ability using crawler under water, and the location tracking device test confirmed the error from the actual location. It is estimated that the use of underwater drones produced through this research will prevent human casualties and achieve economic effects and stability.

Underwater acoustic navigation and position fixing systems have been extensively used not only in surface position fixing but also in underwater position fixing. Tn recently, application of these systems has been in the field of underwater inspection of offshore platforms, where it is vital to track the position of an unmanned submersible or diver carrying underwater cameras and nondestructive testing equipment. But these systems are included the fixing errors as results of a signal with additive noise, the attenuation of sound and the interference effects due to multipath reflection and forward scattering. In this paper to improve the position fixing by the supershort baseline acoustic position system, a method to apply the Kalman filter to the fix of the system is proposed and the digital simulation under noise condition is conducted. The optimal positions by the Kalman filter are compared with original positions, and it is confirmed that the results of the pro-posed method are evidently more accurate.

Today diving activity and technology are indispensable for underwater technology and offshore engineering. And then diving business is still more important to business of subsea. This study surveyed the issue of diving activity in Korea as for compared foreign diving activity. This paper analyzed the status of diving business that include commercial and sport-leisure diving business and development of commercial divers in Korea. This paper reputed the object, the necessity and the character of commercial divers. For the purpose of this study is considered in order to analyze the environment of commercial divers and propose the planning for industrial diving business. Under the present circumstance in Korea this development planning study may be restricted. but the effective planning to activate Korean commercial diving business is abstracted as follows; First, establishment of new course, grade, certificate and licence test for diver is a pre-requisite factor for the successful enactment. Second, the political assistance of concerned government authority is needed. Third, establishment of Korean diving school and medical center for divers are strongly required. Forth, setting up the department of diving activity in university.
