Abstract

Each longitudinally successive module of a longitudinally midbody for a tanker (which is preferably a double-walled tanker), is provided with a longitudinal vertical double-walled bulkhead extending between the top and bottom walls of the module. This longitudinal bulkhead may be provided on the longitudinal centerline of a tanker midbody constructed in accordance with the teachings of Cuneo et al., Ser. No. 07/532,329 and/or Goldbach et al. Ser. No. 07/678,802. Reinforcing structure for the longitudinal bulkhead is enclosed between the transversally opposite walls thereof. Within the longitudinal bulkhead, compartments may be provided for carrying fuel oil and/or cargo tanker slops and/or water ballast. The transversally opposite walls are fabricated of steel plates welded at adjacent edges. Inner plates transversally interconnect the walls at the joints between wall plates. The wall plates may be curved, which is preferred, or flat.
