A system and method for fitting a new inner hull internally over an existing single hull to form a rebuilt double hull vessel. The topside decking and internal vessel structure of the existing single hull vessel is cut and removed and the inner hull structure is inserted within a volume defined by the original hull. The original hull defines an exterior (outer hull) of the rebuilt double hull vessel and the inner hull defines an interior cargo carrying volume and forms a secondary boundary in the event that the outer hull is penetrated. A face bar and filler plate combination is used to connect the new inner hull to the existing outer hull and accounts for dimensional tolerances between the two structures. In addition, detailed ship surveys are conducted to measure the vessel structure and advanced, computerized drafting techniques are employed to improve the fit-up of the new inner hull structure with the existing outer hull structure.
