3Mission Statement of the Joint SNAME-ASNE Ship Design Committee The mission of the Ship Design Committee is to advance the art, science and practice of ship design in the development and construction of naval ships, commercial ships and advanced ships and craft, and the multi-disciplines allied thereto.
4Naval Ships Panel, SD-8Advance development of a more effective standard Naval Ship Design process from requirements determination through delivery of the lead shipFoster continuous improvements through more investment in and implementation of ship design and engineering technologiesProvide a forum to discuss community issues and challenges in order to develop a shared perspective between Government - Industry - AcademiaOffer a forum for the transfer of "best practices" and "lessons learned" between generations of naval ship designersEncourage networking amongst Government - Industry - Academia ship design engineers and other stakeholders in the Naval Ship development processPromote technical papers and other forms of knowledge exchange on Naval Ship Design

Some cost saving practices in new construction shipyards can be at odds with the goal of reducing life cycle costs, especially when the design practices make it difficult for the crew to maintain and modernize equipment. Try to identify those practices.7.

7Issues for Consideration How can we achieve cross-industry representation on this panel?How can we collaborate with other SNAME and ASNE panels?How can we support the development of future ship designers?What gap’s exist in ship design knowledge library that we can help close?How to sustain naval ship design capability, with limited new designs?How can we reduce the so-called “customer factor”?
8Reducing Total Ownership Costs by Improving the Naval Ship Design Process Technical seminar/workshop on March 26, 2010, at the U.S. Naval AcademyA key output from this workshop was a draft paper summarizing our findings and recommendations to NAVSEA 05 and OPNAV N86Paper published in ASNE Naval Engineers Journal
9SummaryShip design community needs to be better aware of fleet technical and logistics issuesEmphasize Maintenance & Modernization Needs in Early Stage Design & Carry the Emphasis Along to Later Design PhasesThe waterfront including the shipyards feel strongly that the ship design and construction ignores too many areas that adversely impact schedules, costs and the ability to care for and modernize our navy surface ships. We can do better.
10What’s SD-8 Doing Next?Follow up SD-8 Workshop at Johns Hopkins University Applied Physics Laboratory (Laurel, MD) in March 2011Continue to explore the issue of life-cycle cost reductionsBegin to explore the question, “What are some ways we can develop surface combatant engineers when we are doing relatively little surface combatant design and engineering?”Opportunity to hear about DDG-51 Flight III Upgrade StudyUpdate to SD-8 Report on Life-Cycle CostsInterested? Contact me atBob Keane has mentioned to me something that one of his mentors once told him, “It’s all about follow through.” I think he’s right. We’re still exploring ways to follow through with some of the recommendations we made at the last workshop. Some ideas we’re considering is looking at some level of specifications to improve the control of arrangements and distributed systems to facilitate maintenance and modernization. We’ve also thought about leveraging some of the work done here and determine where in the ship design process can we help plan for better maintenance and modernization. We know we have a problem with life-cycle costs. SD-8 has taken one step in trying to better understand this problem and come up with some recommendations. We’d like to continue with this them at our next workshop and get more feedback from the wider community on what we can do to reduce life-cycle costs. Earlier I mentioned the importance that I believe professional societies haves, especially today. If you’re interested in helping please contact me.

13Evaluating Rapid Ship Design Environment (RSDE) Toolset for Future Frigate Conceptual Design Studies, Study Guide for, 2012RSDE is an automated high-end toolset that integrates design definition tools with physics-based analysis tools, and uses an enlarged “design space” to account for uncertainty, both in the design and in the requirements.RSDE improves early stage design through visualization of the trade space and generation of many feasible ship design concepts.RSDE allows user to analyze the space of designs for a large number of disciplines at a higher level of fidelity, with results forming behavior objects for multi-disciplinary synthesis, and visualize the design space.This capability leads to an optimized and balanced concept design in a much shorter period of time.
