The invention relates to the field of offshore oil engineering and provides an oceanographic engineering quality control information system. The oceanographic engineering quality control information system comprises a management setting module, a construction quality managing module, a debugging quality managing module, a file managing module and a statistical analyzing module, wherein the management setting module is used for setting a user login password and authorities of a user, setting essential data and preserving welder qualifications; the construction quality managing module is used for determining construction quality acceptance when monitors that information input by a general contractor is examined and approved by an owner party and a third party; the debugging quality managing module is used for acquiring the information input by the general contractor and recording left problems for subsequent elimination; the file managing module is used for uploading, checking and downloading item information; and the statistical analyzing module is used for extracting various data input in the earlier stages according to a user command and giving an analysis result. The oceanographic engineering quality control information system is capable of finishing daily quality inspection work, performing real-time quality information statistics, collecting the statistical information and generating weekly reports and monthly reports needed in working automatically, and the aid of the oceanographic engineering quality control information system, traditional paper file transmission can be replaced to achieve automatic real-time data statistics, so that efficiency in quality management is improved greatly.
