This paper mainly studied the key technology of weight and centre of gravity accuracy control of offshore structures and floaters, developed structural design of weight and centre of gravity data base and realized its main function by using VB and ACESS. And the tolerance distribution calculation formula of weight and centre of gravity of offshore structures and floaters was worked out by utilizing dimension chain principle. The dynamic adjustment and control method of weight and centre of gravity tolerance during construction was raised.
