Real-time analysis system for operation of working ship based on ship attitude measurement

A real-time analysis system for operation of an working ship based on a ship attitude measurement comprising:

• a central processing unit, wherein the central processing unit configured to correct coordinates of a pipeline upper end and a pipeline anchor point of a calculation model and receive sensor data, and manual data, to perform a finite element analysis for the pipeline under various load conditions and store important results into a database;
• a position monitoring unit, wherein the position monitoring unit is used to detect and provide position-attitude information and heading information of the working ship at a predetermined time, and the position-attitude information and heading information of the working ship at the predetermined time are provided to the central processing unit;
• a manual data input unit, wherein the manual data input unit is connected to the central processing unit and provides pipeline model data to the central processing unit in a manual input method;
• and
• a display unit, wherein the display unit is connected to the central processing unit and displays pipeline dynamic response data according to processed data provided by the central processing unit;
• wherein, the coordinates of the pipeline upper end are calculated according to the following equations:
• XA=x+xv·cos h−yv·sin h
• YA=y+yv·cos h+xv·sin h
• wherein, the coordinates of the pipeline anchor point are calculated according to the following equations:
• XB=XA−(L+100)·cos h
• YB=XA−(L+100)·sin h
• AB=180°+h
• wherein, XA is a abscissa of the pipeline upper end, x is a horizontal abscissa of the working ship, xv is a horizontal abscissa of the pipeline upper end with respect to the working ship, yv is a horizontal ordinate of the pipeline upper end with respect to the working ship, h is a heading, YA is an ordinate of the pipeline upper end, y is a horizontal ordinate of the working ship, XB is a abscissa of the pipeline anchor point, YB is an ordinate of the pipeline anchor point, L is a length of a projection of the pipeline located between the pipeline upper end and the pipeline anchor point on a horizontal plane, and AB is an azimuth angle of an embedding-fixing member at the pipeline anchor point.
