Abstract: 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 inde-pendent intellectual property rights in our country, and with international competitiveness, set unilateral cantilever explora-tion system, intertidal zone, offshore drilling, in situ test for the integration of sets of technology.The entire system innova-tion 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 break-throughs in core technologies from Europe and America to our country enterprise monopoly, the outside world to share ex-ploration of overseas market share has a realistic significance.
