SNAME T&R - Multi-Objective Structural Design Space Exploration, Including Minimum Work Content

When:  Aug 12, 2020 from 1:00 PM to 2:00 PM (ET)
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.

Speaker Name & Bio

Tobin McNatt is a partner in MAESTRO Marine LLC, a business started in 2017 to continue the development, distribution, and technical support of the MAESTRO ship structural design and optimization technology and software. He has developed and managed numerous technical programs which utilize the MAESTRO code for U.S. Shipbuilders, NSRP, NAVSEA, NSWC Carderock Division, Office of Naval Research, U.S. Special Operations Command, DARPA, and several ship classification societies. He is a plankowner of fast attack submarine USS Birmingham (SSN 695) and served on the USS Francis Scott Key (SSBN 657) conducting strategic deterrent patrols. Tobin is a graduate of the U.S. Naval Academy with a degree in Physics.
