After a brief introduction of structural design procedure for double hull tankers, their design features are firstly highlighted comparing with conventional single hull tankers. Next discussed are recent topics of double hull VLCC (Very Large Crude oil Carrier) including higher tensile steel and strut arrangement in transverse ring frames. Finally ultimate longitudinal strength of hull girder is analyzed through a simplified method under both sagging and hogging conditions. Making use of this result, some considerations are made on structural reliability of double hull VLCC.
