System and method for internally fitting a new inner hull to an existing outer hull to form a rebuilt double hull vessel

A double hull vessel rebuilt from an existing single hull vessel comprising:

• an outer hull of said existing single hull vessel;
• an inner hull disposed within a volume defined by said outer hull so as to define a double hull;
• and
• a plurality of framing members disposed between said inner hull and said outer hull, wherein said framing members comprise connecting members that maintain said inner hull in a spaced apart relationship to said outer hull, and stiffening members that stiffen said inner hull and said outer hull;
• wherein said connecting members further comprise:
• inner transverse framing members;
• a plurality of slots in said inner transverse framing members;
• an inner hull connecting member extending from an exterior surface of said inner hull toward said outer hull and having a distal end;
• an outer hull connecting member extending from an interior surface of said outer hull toward said inner hull and having a top end;
• a face bar connected to one of said inner hull connecting member and said outer hull connecting member;
• and
• a filler plate connected to said face bar and one of said inner hull connecting member and said outer hull connecting member, to which said face bar is not connected;
• wherein said stiffening members comprise inner longitudinal framing that extend from said exterior surface of said inner hull along a longitudinal length of said vessel and pass through said slots in said inner transverse framing members, said inner hull defines an interior cargo carrying volume, and said outer hull defines an exterior of said double hull vessel, such that said inner hull provides a boundary in the event that said outer hull is penetrated.
