This book was released on 1992 with total page 31 pages. Available in PDF, EPUB and Kindle. Book excerpt: In October 1989, A Ship Design for Producibility Workshop was held by the Naval Sea Systems Command (NAVSEA) at the David Taylor Research Center (DTRC). The purpose of the workshop was To develop the framework of a plan to integrate producibility concepts and processes into the NAVSEA Ship Design Process. The major recommendations of the workshop included initiatives related to increased training of NAVSEA design engineers in modem ship production concepts, development of producibility design tools and practices for use by NAVSEA design engineers, improved cost models, implementation of produability strategies for ship design process improvements, modification to existing acquisition practices, and improved three-dimensional (3-D) digital data transfer. The workshop was one of NAVSEA s first Total Quality Leadership (TQL) initiatives and was subsequently expanded into the Ship Design, Acquisition and Construction @AC) Process Improvement Project. This paper reports on the major findings and recommendations of the workshop, the near term accomplishments since the workshop, and the long range strategic plan for continuously improving producibility in the Naval Ship Design Process.

This book was released on 1992 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Mid-Term Fast Sealift Technology Development Program producibility study was undertaken by the Manufacturing Systems Division (Code 125) of the Naval Surface Warfare Center, Carderock Division (NSWC) for the Naval Sea Systems Command Computer Aided Engineering Division, Ship Design and Engineering Directorate, SEA 507. The producibility project team was initially tasked to identify and evaluate possible design improvements with regard to their potential impact upon the cost of construction for the Baseline (BL) Oa rough order of magnitude (ROM) geared-diesel option. This particular design varient is a 30 kt twin screw, 289 m (948 ft.) roll-on/roll-off (RO/RO) vessel with four 18 PC4.2V medium speed diesels producing 85,619 kilowatts (114,817 h.p.) of installed power. The construction cost estimate developed by NAVSEA for this particular design varient is $385 million per ship (I). In addition to the NAVSEA-assigned task, the team reviewed the producibility aspects of the Navy auxiliary ship procurement process with regard to finding methods that would facilitate major reductions in the construction contract cycle, as time is now recognized as a major cost driver in ship procurement (2). The construction contract cycle is defined as the amount of time from construction contract award to delivery, and was estimated by NAVSEA to be 42 months for this particular design varient (3).

This book was released on 1992 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Initial zone technology implementation at the Philadelphia Naval Shipyard (PNSY) in 1986 set the stage for one of the most significant shifts in culture and repair philosophy ever witnessed at a public naval shipyard. Attempting to fundamentally change the way that the shipyard conducted business forced senior and middle management to completely understand the dynamic and interrelatedprocessesthatwere utilized to perform depot level work. Through the Philadelphia Quality Process (PQP), this understanding was achieved and changes that were necessary to shift from a Ship Work Breakdown Structure (SWBS) to a Product Work Breakdown Structure (PWBS) began.

This book was released on 1992 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is customary for a shipyard to subcontract with one or more design agents for at least some portion of the detail design of a ship to be constructed by the shipyard. Past experience with this process has demonstrated that it has the potential to be the source of inefficiencies, wasted efforts and deteriorated relations between the shipyard and design agent. The Society of Naval Architects and Marine Engineers (SNAME) Ship Production Committee Panel, (SP-41, Design/Production integration, sponsored a project to improve this process. This effort developed a list of the information which should flow from a shipyard to a design agent in order for the design agent to generate the calculations, drawings and other deliverables in a timely fashion and useable format to support the construction effort. This paper describes the methodology used to develop the required information and reviews the details of the list.

This book was released on 1992 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of Computer Aided Design (CAD) technology in the U.S. Navy and Marine industry has evolved from a drafting based design tool to a 3-Dimensional(3D) product oriented information base, used for design, production and service lift support. One of the most significant enhancements to current CAD technology has been the incorporation or integration of non-graphic attribute information with traditional graphics data. This expanded information base or product model has enabled the marine industry to expand CAD use to include such activities as engineering analysis, production control, and logistics support. While significant savings can be achieved through the exchange of digital product model data between different agents. current graphics based CAD data exchange standards do not support this expanded information content.

Book excerpt: The production of large FRP vessels for military missions is underway in shipyards throughout the United States. These vessels. in many cases, can be built to commercial standards using guidelines already in place. These guidelines are developed through interfaces with private industry and experienced production personnel. By binding the builder to a set of military specifications which detail the entire production process the vessel cost of construction is increased.

This book was released on 1990 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: After years of studies, reports, formal and informal discussions, Naval ship producibility is becoming accepted as a necessary ingredient in any recipe for affordable, effective warships. However, within both the Navy ship design and private ship construction communities, the word producibility has come to evoke a wide variety of reactions. While there is general agreement that producibility has to do with lowering ship costs, there is not yet a consensus on how those costs are to be attacked, what factors are the most important, and what the roles of the various participants should be. In order to answer these and other questions, and to form a consensus within the Navy design community that will be compatible with external as well as internal relationships, the Naval Sea Systems Command (NAVSEA) has sponsored a series of steering committee meetings and a workshop on producibility as part of its ongoing research. The purpose of these meetings and workshop is to clarify the meaning of producibility, the needs of the design and construction communities, and to determine critical actions which will enable NAVSEA to integrate producibility more thoroughly into the Naval ship design process.
Download or read book The National Shipbuilding Research Program 1989 Ship Production Symposium Paper No 2 Producibility in U S Navy Ship Design written by and published by . This book was released on 1989 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent NAVSEA studies of a twin skeg hull form design applied to a T-AO type ship indicated many areas of possible improvement in producibility. This paper reviews the findings of producibility studies and attempts to indicate specific areas where an improvement in producibility and attendant cost savings for Navy ships are possible without any degradation in ship performance and survivability. Most available studies on producibility have an inherent trait of elaborating on details of shipyard producibility. This paper attempts to confine itself to the producibility aspect of the design phase, ending with the completion of contract design. While it is of course necessary for the Navy ship designer to know about producibility details of prospective building yards, he must be careful not to incorporate any details that may be restrictive on some of the prospective builders and thereby hinder competition.

This book was released on 1992 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the current severely competitive climate that is challenging shipbuilders everywhere, how information is managed is taking on extraordinary importance. Existing computer aided design (CAD) systems have not been focused on the most critical information needs, for example, information to serve marketing. This limitation is the result of concentrating primarily on aspects of design and manufacturing without regard for impact on an overall manufacturing system. In this paper the need to extend CAD systems is identified so that they would more fully provide critical-data to everyone who has to have understanding of a manufacturing system's capability and availability.

This book was released on 1989 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: David Taylor Research Center is just commencing investigations into a new manner of defining future fleet architectures. The cost of current performance-driven ship designs has increased at a rapid rate. While it is true that a warship designed with insufficient performance is of meager utility it is also true that the heat performing warship design is of no utility if never built. Both performance and affordability are required if sufficient numbers of ships are to be built to counter the threat. By designing a future fleet architecture with producibility as a major requirement from the start we hope to impact the acquisition cost significantly. One battle force concept titled Distribute, Disperse, Disguise and Sustain suggests two fundamental surface ship types; the Carrier of Large Objects (CLO) and the Scout Fighter. A CLO feasibility design in progress Carrier Dock Multimission is outlined to inform shipbuilding researchers of an initiative that promises to have significant impact on naval ship procurement and provide increased visibility within the U.S. Navy on producibility issues.

This book was released on 1992 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The bastion of the white-collar segment within the typical shipyard has rarely been penetrated by outside influences, especially under the banner of productivity improvements. This paper will discuss enlisting the talents of both white and blue collar employees to gain some advantages in this area. The technique espoused here is the empowerment of selected employees at the operational level through the use of Action Teams. This is the level at which daily shipyard operations are conducted, above the worker level and below the management level. A recent project sponsored by SNAME Ship Production Committee Panel SP-5 on Human Resources, and performed under the National Shipbuilding Research Program (NSRP), conducted a hands-on application of this theory in a small shipyard with favorable results.
