Gas Hydrate Research Vessel Feasibility Study

The energy becomes a strut condition which maintains the national economy and the social sustainable development, At present, our country land oil gas resources year by year drops, the oil gas supply is serious insufficient, because the energy lacked already affects our country economy development. The preliminary estimate, in 2010 our country petroleum demand will amount to 300 million tons approximately, the gap nearly 100 million tons, the import petroleum surpasses the national energy structure safety line according to the forecast.Seeking the new energy and the adjustment energy structure has become the urgent matter, At present, many advanced countries have already for sought the substitution energy launched the comprehensive research, and has determined the natural gas hydrate for the future substitution energy, And already gain the natural gas hydrate sample by many kind of way, after 21st century 30's, world fossil energy resources supply gradually will drop, in future energy structure which requires more highly effective and the environmental- protected natural gas will gradually substitutes for the petroleum and will become the primary energy. Under such situation, in 2001, State Council premiers made the written comment especially on this matter and requests correlation unit to launch the research in light of this. In 2003 the sea area natural gas hydrate investigation special has obtained the authorization, how to carry out the investigation and complete the natural gas hydrate investigation project, survey this kind of energy ~ natural gas hydrate existence, and how to obtain the sample of the energy, this request a kind of tool to be able to complete this kind of research: Motion experimental platform. The ship has become this kind of motion experimental platform carrier. Which type of ship can satisfy the need has become the research goal.This article first illustrate the necessity to constructs the ship according to the present international form to the energy developmental strategy condition .Second, according to the condition of the natural gas hydrate saves of characteristic: The natural gas forms the natural gas hydrate under the certain temperature and the pressure, at present in the world carries on the analysis to the natural gas hydrate research and the survey method, from aspect and so on body form, advanced investigation method by satisfies the hydrate investigation primarily, through tabulated research technique and so on the correlation method, synthesis analytic method, non-linear gauge the investigation instrument type which needed to this ship parameter has conducted the analysis research.Third, this ship basic design principle had determined the appropriate bodies form through the research the shipboard equipment, special purpose equipment. Especially the ship can do the geological and the geophysics investigation which is the different body form to carry on the analysis, and provides one kind to carry on the modeling through the nonlinear programming to provide the analysis method to this ship dynamic positioning ability research.Finally acted according to the massive investigation and study the fund which needed to this ship construction to carry on the estimate, carried on the analysis from the national developmental strategy to this ship benefit.
