Currently Mr. Lynaugh is the on-site ship design manager for LHD-8 at Ingalls Shipyard in Pascagoula Mississippi.

Cracking was discovered in the openings of cargo deck tie down fittings on ships under construction. There was a distinct possibility that these cracks could propagate through the fittings and into the strength deck plating, affecting the ships hull integrity. With more than 14,000 fittings installed on each ship, the appearance of approximately 400 cracks at the mid-ship area of the main and lower decks raised production and operational concerns. This paper will discus the successful application of a Root Cause Failure Analysis (RCFA) methodology employed by a Corrective Action Team (CAT) establish to solve the problem. Through their efforts and the systematic application of RCFA, various failure hypotheses were validated or discounted and consensus was achieved on the appropriate corrective action.

NAVAL ENGINEERS JOURNAL 2000年第3期112卷 97-110页

作者： Chewning, IM Moretto, SJ Irvin M. Chewning:is currently the Director of the Aircraft Carrier Cost Estimating and Industrial Analysis Group of the Naval Sea Systems Command. Over the past four years Mr. Chewning has guided the cost analysis effort for the new CVNX class aircraft carrier through a three-part analysis of alternatives and is currently steering it towards Milestone I in June of 2000. In 1999 the CVNX cost analysis team was presented the NAVSEA Association of Scientists and Engineers “outstanding team achievement” award for its work on the CVNX analysis of alternatives. Mr. Chewning's professional career includes over 16 years as an employee of Newport News Shipbuilding as a Pipe Fitter Piping Systems Designer Piping Systems Engineer and Cost Engineer. He has worked at the Naval Sea Systems Command since 1980 as a Senior Cost Analyst Branch Head and Deputy Division Director of the Cost Estimating and Analysis Division. He has preformed cost analysis work for virtually all USN combatant programs including submarines cruisers destroyers frigates and aircraft carriers. He also performed the cost analysis work for the OSD evaluation of the Israeli Naval Modernization Program in the 1980's. Mr. Chewning is also Chairman of the NATO Specialist Team on Ship Costing a subgroup of the NATO Naval Group Six on Ship Design. Under his leadership two Allied Naval Engineering Publications have been completed in the 1990's: ANEP-41 on Ship Costing and ANEP-49 on Ways to Reduce Costs of Ships. In 1999 the NATO Specialist Team on Ship Costing completed a paper titled “Manpower Reduction and the Use of Commercial Standards and Practices to Reduce Costs of Ships.” The result of this work will be incorporated in a future revision of the aforementioned ANEFs. Mr. Chewning is a graduate of North Carolina State University with a Bachelor of Science in Mechanical Engineering. Mr. Chewning has also completed courses at the University of Virginia and Christopher Newport University Mr. Chewning is a graduate of the Program Management College

The U.S. Navy recently conducted an analysis of alternatives (AOA) to set the stage for determining the characteristics and acquisition strategy for its next generation aircraft carrier. The platform design selected is expected to be in service throughout the 21st century. The parameters under consideration for change in the new carrier design lie in the areas of propulsion and electric power generation, aviation, survivability, service life, and total ownership cost (TOC) reduction. The issue of affordability is paramount This paper focuses on the need for the program management office and its supporting cost analysis staff to understand the life cycle cost (LCC) of the existing and proposed future aircraft carriers and to then translate these LCC's into meaningful information for cost-conscious decision making. The challenge is to relate the LCC in terms the key decision-makers and the engineering team can use to satisfy their respective roles. Thus, it is necessary to translate the results of the given ship design alternative LCC's into the paradigms of the respective stakeholders: Fleet User (operators of aircraft carriers) Ship Designers (translators of the fleet operator requirements) program Sponsors (providers of the funding resources) program management Office, Ship builder and Supporting Industry (executors of the acquisition and construction of the ship) Navy and OSD decision-makers (overseers of program execution) The paper describes the aircraft carrier LCC breakdown structure that has resulted, in part, from a recent navy/shipbuilder integrated product team effort to capture total ownership costs. The structure has been used in the AOA as a tool to identify cost drivers and to add the time element to the cast equation in order to perform return on investment and program affordability analysis. The expanded ship work breakdown structure (ESWBS) has emerged as the central backbone of the cost work breakdown for AOA work. The ESWBS structure is a natural

A prototype system was developed to test the applicability of a dualmethod information-filtering model for filtering e-mail messages: content-based filtering and sociological filtering implemented with user stereotypes. This paper reports the main results of experiments that were run to determine the effects of combining the two methods in various ways. A major outcome of the experiments is that the combination of both methods yields better results than using each method individually. The optimal combination of the two filtering methods is stereotype dependent. © Springer-Verlag Berlin Heidelberg 1999.

NAVAL ENGINEERS JOURNAL 1999年第3期111卷 111-124页

作者： Brougham, WJ Lt. William J. Brougham:is an Engineering Duty officer (ED) in the Navy undergoing advanced studies at the Massachusetts Institute of technology. He has had tours as a submarine line officer as well as a Program Manager's Assistant for Weapons System Safety Test and Evaluation at NAVSEA PMS-350 before transferring into the ED community. Current studies include dual masters degrees in naval construction and engineering and mechnical engineering from MIT as well as a master of science management of technology (MOT) from the Sloan School of Management MIT. He has an MBA finance and investments from The George Washington University (1996) and a BS general engineering/control systems from the University of Illinios-Urbana (1988). He is a member of both the American Society of Naval Engineers and the Society of Naval Architects and Marine Engineers.

The Coast Guard wants to replace their aging cutter fleet. The new construction Deepwater Project would like to integrate their efforts with the DD 21 family of ships but the Coast Guard does not want to wait for the Navy program to mature. This study investigates the engineering feasibility of an alternate near term solution-conversion of the decommissioning Oliver Hazard Perry class frigates into Future Coast Guard Cutters (FCGC). Detailed analyses for combat system selection, propulsion plant and endurance range Limitations, and manning and automation issues form the foundation for new ship arrangements capable of supporting a mixed gender crew. Additional analysis reviews small boat operations, habitability requirements, ship stability structural loading, and a cost estimation technique. The converted Oliver Hazard Perry class frigates were shown to provide a technically feasible interim solution to replace decommissioning Coast Guard cutters while meeting or exceeding the Coast Guard requirements for a conservatively estimated cost of $141M (FY98).

In the Fiscal Year 1996 National Defense Authorization Act, Congress amended the Clean Water Act to provide the Department of Defense and the Environmental Protection Agency authority to jointly establish standards for incidental discharges from Armed Forces' vessels. The uniform national standards would apply to discharges from vessels of the Navy, Military Sealift Command, Army, Marine Corps, Air Force, and Coast Guard to the navigable waters and contiguous zone of the U.S. and its territories. Uniform National Discharge Standards (UNDS) will require control of discharges, by either a technology or management practice. UNDS will facilitate the Armed Forces' ability to better design and build future vessels to be environmentally sound and to maintain the operational flexibility of Armed Forces' vessels both domestically and internationally. The development of standards for Armed Forces' vessel discharges may have greater impact on naval engineering requirements for future vessels than any other single environmental issue, These standards are expected to stimulate the development of innovative vessel pollution control technologies, which on be used for both Armed Forces' vessels and commercial shipping vessels. This paper provides an overview of UNDS development, summarizes the results of UNDS Phase I, provides a summary overview of the preliminary approach for accomplishing UNDS Phase Il, and discusses implications for future naval engineering efforts.

The past twenty-five years has been marked by the introduction ed marine environmental regulations that have had a profound effect on how ships are designed, built and operated. Ships being designed and built today must accommodate not only current regulations but anticipate those enacted over their thirty to fifty year life cycles. U.S. Chief of Naval Operations, Office of Environmental, Safety and Health (CNO N45) has articulated a vision for the Environmentally Sound Warship of the Twenty-first Century. This vision incorporates the "Sense of Congress" for a naval ship designed to operate in full compliance with environmental regulations worldwide. The task of the Navy engineering team is to translate this vision into reality;a ship capable of prevailing in time of war and able to conduct operations in all areas of the globe, unencumbered by special procedures for environmental compliance. The keys to this warship design are the early integration of environmentally sound principles, materials, and processes into the ship acquisition process;minimization of both hazardous materials and generation of post shipboard consumer waste during operation;adaptation of integrated systems to reduce the volume of wastes and enhance processing efficiency;reduced manpower requirements;and crew indoctrination in environmental protection.

The road to Impeccable -: An uncommon approach to ship acquisition

引用

NAVAL ENGINEERS JOURNAL 1999年第3期111卷 245-255页

作者： Shen, TWT Proctor, BL Saha, D Mr. Terry Shen:is the Assistant Project Manager for the Ocean Surveillance Ship (T-AGOS 23) Acquisition Project at Naval Sea Systems Command (NAVSEA). He is responsible for the program management of the large SWATH (Small Waterplane Area Twin Hull) ship construction in the Gulf region. Mr. Shen has over 14 years of experience in ship acquisitions and has co-authored several technical papers published by the Association of Scientists & Engineers the Society of Naval Architects & Marine Engineers and the American Society of Naval Engineers. He is a graduate of the University of Maryland with a BS in aerospace engineering and a BA in speech communication a 1986 graduate of the DSMC Program Management Course and a 1991 graduate of the Virginia Polytechnic Institute with an MBA in business administration. Mr. Barry Proctor:is NAVSEA's Ship Design Manager for the T-AGOS 23 program. He has held this position since March 1997. Prior to that time he was NAVSEA's Ship Design Manager for the T -AKR 300 class vessels. He has over 18 years of experience as a Naval Architect for NAVSEA (O3D). He has a BS in civil engineering from the University of Maryland and an MS in naval architecture and marine engineering from the University of Michigan. Mr. Deepak Saha:provides design support to NAVSEA's Program Office and Ship Design Manager on the T -AGOS 23 ship acquisition. His involvement with the program started at the time the first shipbuilder declared bankruptcy. He is Manager of the Commercial Ship Design Group at M. Rosenblatt & Son Inc. (MR&S) Arlington Branch. He has over 26 years of experience as a marine engineer and naval architect. He obtained a BS in marine engineering from Calcutta India in 1972 and a BSE in naval architecture from the University of Michigan in 1983. He also holds a Chief Engineer's License (Unlimited Horsepower Diesels).

The road to the acquisition of the USNS Impeccable (T-AGOS 23) has seen a few uncommon and challenging twists and turns, resulting in delays and disruption to the program. The saga began in 1993, when the original shipbuilder, facing financial difficulties, filed for Chapter XI bankruptcy protection. For two more years the program was stalled before the Navy was able to warrant the work that had been done up to that point. In 1995 the contract was reassigned to another shipbuilder to complete the vessel and obtain the necessary certificates to comply with all the applicable requirements of the American Bureau of Shipping (ABS). This unprecedented approach put the Navy in the unique situation of being responsible for two of the most controversial issues in a ship construction process, i.e., detail design and equipment warranties. This paper gives the status of the program, discusses how various technical issues and production demands are being addressed, and describes the future hurdles that need to be overcome before delivery of the vessel.

NAVAL ENGINEERS JOURNAL 1999年第3期111卷 293-306页

作者： Benson, J Caplan, I Jacobs, R John Benson:received his BS degree in Mechanical Engineering and MS degree in Environmental Engineering from the University of Maryland. He is a registered Professional Engineer in the State of Maryland. He Joined the Naval Sufrace Warfare Center Carderock Division Environmental Quality Department in 1990 as a project engineer and is now managing the non-oily wastewater (graywater and blackwater) project area. Mr. Ivan Caplan:graduated from Drexel University (Philadelphia Pennsylvania) with a BS in Metallurgical Engineering and was awarded a MS degree from the Johns Hopkins University (Baltimore Maryland) in Mechanics and Materials Science. Mr. Caplan has spent most of his career at the Carderock Division Naval Surface Warfare Center (NSWC) and is currently the Head of the Wastewater Management Branch in the Carderock Division's Environmental Quality Department. Previously Mr. Caplan managed the US Navy's Applied Research Program in Ship & Submarine Materials Technology. In addition Mr. Caplan was manager of the US Navy's Titanium Technology Program Office and during his government career held several external Program Manager positions on at the Naval Sea Systems Command and another at the Air Force Office of Scientific Research. Rachel Jacobs:received BS degrees in Chemical Engineering and Marine Biology from the University of Maryland College Park. After working for the Naval Research Laboratory in Washington DC and the Center for Marine Biotechnology in Baltimore MD she joined the staff of the Naval Surface Warfare Center's Environmental Quality Department in 1997. Since thta time Ms. Jacobs has worked in the non-oily wastewater treatment area and her principal responsibility has been to technically supervise the evaluation operation and modification graywater treatment.

In anticipation of more stringent environmental regulations, the increasing costs of waste disposal, and the need for naval combatants to operate unimpeded in littoral waters, the U.S. Navy has identified the need to develop technologies which are appropriate for the control and treatment of blackwater and graywater. This paper will describe the status of development efforts by the Carderock Division, Naval Surface Warfare Center (CDNSWC) and its supporting contractors, under sponsorship of Naval Sea systems Command (NAVSEA) and the Office of Naval Research. The challenge was to develop treatment systems that meet Navy shipboard requirements for affordability, compactness, low manning/maintenance, high reliability and safety, and EM, noise, vibration and shock. Membrane ultrafiltration based systems, incorporating aerobic biological pre-treatment and ultraviolet light post treatment disinfection, have ken developed to meet these requirements. Both external and in-tank membrane systems will be described in terms of performance, system operation and space and weight advantages.
