The general objective of this research is to develop a ship structural design and optimization modeling and simulation capability that shipbuilders will utilize to enable ship structures to be holistically designed 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.
The project team will leverage a mature software system that is already in use within the US Navy’s ship design and shipbuilder community, within the US Navy’s internal ship design groups at NAVSEA and NSWC Carderock Division, and within the US Coast Guard—specifically, the MAESTRO ship structural design and optimization code.
The technical strategy involves taking a baseline, existing MAESTRO system into the shipbuilders’ environment with the project team members to rigorously wring out and groom the structural optimization system to reflect shipbuilder producibility objectives. The specific tasks planned for this project are:
- Identify MAESTRO Improvements to be implemented
- Develop the MAESTRO Improvements
- Conduct Testing and Demonstration
Tasks 1, 2 and 3 will each be performed in an iterative, six-month phase within the proposed two year program. Each cycle will be used to review the required new improvements, their respective status of implementation and testing, and to set the implementation and testing requirements for the new six-month cycle.
KEY DELIVERABLES / BENEFITS
Upon completion the project team expects to have accomplished the following:
- Demonstrated the effectiveness of structural optimization
- Demonstrated that a comprehensive evaluation of the ship structure’s performance versus design safety criteria can be automated
- Shown that shipbuilders can improve the producibility of the structure
- Demonstrated structural life-cycle monitoring and assessment
