Taking the rebuilt ship"Star of Haizhou Bay"as an example,this paper demonstrated the method of calculating the weight distribution and the gravity of the center for the original ship by using the principle of hydro-statics in the absence of the initial weight distribution data.By adopting this method,this paper calculated the total longitudinal strength of the original ship based on the weight distribution and the center of gravity of the original ship and obtained the recognition of the classification society,providing a reference for the peer.
