Team: MAESTRO Marine LLC Prime; Team Members: Fincantieri Marinette Marine, Altair Engineering Inc., American Bureau of Shipping, U.S. Coast Guard, Surface Forces Logistics Center, Robert Keane – Ship Design USA, Inc., P. Jaquith & Associates, SPAR Associates, Inc.
The project team represents the U.S. shipbuilding enterprise including a key shipbuilder, a global leader in engineering simulation software tools, a major Government group of ship engineers, owners and operators, the major U.S. Ship Classification Society, ship design, lean design, production planning and cost estimating specialists — and is primed by the developers of the software being leveraged for the project.
The project aims to enhance ship structural design for increased steelwork throughput, automate U.S. Navy structural design criteria evaluations, develop advanced structural modeling and rigorous structural design space exploration to ensure structural integrity performance, reduce excessive in-service structural damage and repair costs, and leverage these capabilities through an integrated structural optimization software toolset.
National Shipbuilding Research Program Selects $2.55 Million for Panel Project Portfolio
The Executive Control Board of the National Shipbuilding Research Program (NSRP) has selected 13 panel projects for award as part of the Program's continuing mission to reduce costs and expand capability for U.S. shipbuilding and ship repair. These new projects, valued at over $2.55M in government funding, were among those proposed in response to the Panel Project Solicitation issued in June 2024.
Integrate MAESTRO Ship Structural Design Software with Femap/Nastran Software
MAESTRO Marine | HII - Ingalls Shipbuilding | Siemens Government Technologies, Inc. | Duration: 12 Months
Objective: The project goal is to improve the current state of design tools and practice by integrating the ship-specific MAESTRO software tools, including automation of design criteria evaluation and optimization with the Siemens Femap/Nastran finite element analysis software that is widely used throughout the U.S. Naval ship design and in-service engineering enterprise. The goal is to make the structural design process faster, more accurate, and more agile.
U.S. Navy DDG(X) Concept Design: Next-Generation Guided-Missile Destroyer
MAESTRO Marine is working with U.S. Navy led Design Team, including shipbuilders HII Ingalls Shipbuilding and GD/Bath Iron Works, to apply MAESTRO to develop ship structural design alternatives in early-stage design, supporting design alternatives/optimization for fabrication efficiency, lean design, cost and weight reduction, and robust service-life performance.
The Navy’s DDG(X) program envisages procuring a class of next-generation guided-missile destroyers (DDGs) to replace the Navy’s Ticonderoga (CG-47) class Aegis cruisers and older Arleigh Burke (DDG-51) class Aegis destroyers. The Navy wants to procure the first DDG(X) in FY2032. The Navy’s proposed FY2025 budget requests $102.8 million in research and development funding for the program.

The proposed NSRP RA Project addresses the problems of inadequate structural performance in-service, and of unsustainable structural maintenance costs at two levels which define the project’s general objectives: to enhance early-stage ship structural design for producibility and to improve in-service ship structural integrity assessment.
This project will implement into design and production planning software the accomplishments of NSRP RA Project 2017-443 and develop a new generation of ship structural design optimization tools for early-stage design that will result in:
Assurance that structural design criteria are met while improving structural producibility and reducing design-build cycle time;
Improving structural design and service-life assessment to reduce service-life corrosion, heavy weather damage, and structural fatigue cracking while mitigating excessive structural repair and maintenance costs and increasing ship availability;
Provide comprehensive structural design space exploration capability for U.S. Navy and shipbuilder early-stage ship design processes resulting in robust structures with reduced Total Ownership Costs (TOC) of ships for the U.S. Navy and U.S. Coast Guard.

Ship Structural Design Optimization for Improved Producibility and Enhanced Life-Cycle Performance

April 2017 – March 2019 | INDUSTRY INVESTMENT: $974K | NSRP ASE INVESTMENT: $999K
The objective of this research was to develop a ship structural design and optimization modeling and simulation capability that shipbuilders will be able to 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.
This project showed that higher fidelity structural modeling combined with producibility-oriented design optimization will result in improved quality of ship construction, reduced costs during ship construction, modernization and maintenance and reduction in Total Ownership Costs (TOC) of ships for the U.S. Navy and U.S. Coast Guard. This research project created and demonstrated a Ship Structural Design & Optimization (SSDO) system with the capability to conduct structural design space exploration using full ship finite element analysis, failure mode evaluation and optimization of the ship’s global structure in the early stages of design to Navy standards in order to reduce weight, meet safety performance criteria, and reduce both production costs and in-service repair and maintenance costs.
