In order to speed up China’s offshore engineering geological exploration in line with international standards of quality, reduce the exploration cost, participate in the overseas market competition, to carry out the sea (water) into the shipborne drilling platform innovation design and engineering application. This paper introduces a with completely independent intellectual property rights in our country, and with international competitiveness, set unilateral cantilever exploration system, intertidal zone, offshore drilling, in situ test for the integration of sets of technology. The entire system innovation in the offshore engineering geological exploration technology, formed a set of suitable for beaches, lakes, rivers and the sea (water) regional exploration and in-situ test, and the exploration quality reached the international standard. The breakthroughs in core technologies from Europe and America to our country enterprise monopoly, the outside world to share exploration of overseas market share has a realistic significance.
