Structural design during early stage or concept-level ship design has historically been addressed as a following design factor. The ship arrangement was developed first, and structural components were selected for that arrangement, and sized using efficient calculations – typically for 2D hull cross sections. A recent National Shipbuilding Research Program (NSRP) Research Announcement project, “Ship Structural Design Optimization for Improved Producibility and Enhanced Life-Cycle Performance” had objectives to develop ship structural design and optimization capability that shipbuilders can utilize to design ship structures to meet structural performance and safety criteria, facilitate optimization for producibility, and simultaneously enhance structural life-cycle, in-service performance, and generate total ownership cost reductions. This work included development of a Concept Design/Topology Optimization Module which allows for the global optimization of a ship’s structure while automatically varying frame spacing and stiffener spacing to user defined values. The webinar will reflect progress made on this structural topology optimization capability.
The webinar will include material from SNAME T&R Bulletin 7-11 (2017) Lean Design Guide for Pre-Contract Design and NSRP Research Announcement project: “Ship Structural Design Optimization for Improved Producibility and Enhanced Life-Cycle Performance” (NSRP ASE TIA 2017-443). The SNAME Ship Production Committee and Ship Arrangements SD-4 Panel (under the Ship Design Committee) have showcased this work.
