MEDIUM-SPEED DIESEL PROPULSION REDUCTION GEARING

NAVAL ENGINEERS JOURNAL 1994年第3期106卷 29-40页

作者： PHINNEY, JM The Author:is the senior application specialist for the enclosed drive group of the Philadelphia Gear Corporation where his responsibilities include conceptual design and quotation of sophisticated equipment in the marine propulsion special products industrial gear products and high speed products areas. Prior to joining Philadelphia Gear Mr. Phinney's career included positions as Engineering Supervisor at Newport News Shipbuilding Director of Product Engineering for SKF Industries Manager of Engineering for Propulsion Systems Inc and Chief of Design Engineering for High Speed and Marine Drives at the Falk Corporation. The scope of his marine experience includes management design of propulsion equipment and logistic support for military and commercial vessels ranging from fishing vessels to aircraft carriers. Mr. Phinney is a graduate of Antioch College earning his BSME in 1963. A member of ASNE since 1985 Mr. Phinney is a past member of the National Council representing the mid-Atlantic region. He is active in the Delaware Valley Section where he heads the Awards Committee and previously served as the section Chairman Vice Chairman and Program Committee head. He has also been active in other engineering societies with several papers to his credit.

Current interest in medium speed diesel propulsion for maritime vessels is driving a third generation of reduction gear designs. The first generation nourished in the 1930s and looked remarkably like those proposed today. However, by comparison, they were designed with low power density;used lightly loaded gear teeth and bearings;had to cope with poorly filtered and blended lubricants;used relatively inaccurate manufacturing techniques, and were based on inaccurate analysis of operating conditions. The second generation, starting in the late 1960s and continuing through 1980, had the benefit of the rational AGMA gear design method, Raimondi and Boyd's work on bearing design, and sophisticated techniques for alignment and vibratory analysis. Power and loading levels increased and many variations of equipment were tried: reversing engines, reversing gears, and reversing propellers. Individually, each was successful and we now have the benefit of two decades of operating experience for this design generation. This paper will explore the design principles of the gear/engine/propeller/auxiliary equipment package to define the guiding parameters for the third generation based upon the lessons provided by the experience gained in the two previous generations.

To establish a planning basis for future avionics systems, the Naval Air systems Command (NAVAIR) conducted an avionics architecture investigation during 1992-1993, culminating in a final report published in August 1993. In the course of the study, U.S. Industry provided significant information to a NAVAIR avionics database for both technologies and systems integration methods. From the study emerged an implementation strategy to allow NAVAIR to develop effective avionics systems in the future that use commercial products and standards where applicable but also allow the ready use of new and emerging technologies. Recommended strategies concentrate on the development process, especially the use of sound systems engineering techniques and the maximum practical use of commercial standards and products. This paper reviews the methodology employed during the NAVAIR investigation, and presents the key findings and resulting implementation strategies. The paper concludes with a brief summary of current implementation plans at NAVAIR.

His research and consulting interests include statistical modeling statistical computation simultaneous inference and data analysis.

Ground water monitoring presents interesting statistical challenges, including controlling the risk of entering compliance monitoring, incorporating all modes of inherent variability into the statistical model on which tests are based, and taming the detection limit problem, all while maintaining demonstrable sensitivity to real contamination. Some of these challenges exceed textbook statistics considerably, even when considered alone, and good solutions are scarce. When these challenges are combined, the task of developing good statistical procedures or good regulations can be formidable. This article presents a number of realities of ground water monitoring that should be considered when developing statistical procedures. Recommendations made for addressing these realities include the following: (1) the false positive rate should be controlled on a facility-wide basis, rather than per well or per parameter as required in the proposed regulation (40 CFR §264); (2) multiple comparisons with control procedures are preferable to analysis of variance (ANOVA) for controlling the overall false positive rate; (3) retests can be made an explicit part of the statistical procedure in order to increase power and decrease sensitivity to distribution shape assumptions; (4) commonly used simple methods of handling below detection limit data with parametric tests, including Cohen's procedure as implemented in the U.S. EPA's Technical Enforcement Guidance Document (TEGD), should probably be avoided; (5) the statistical properties of practical quantitation limits for non-naturally occurring compounds should be studied carefully; and (6) so long as the facility-wide false positive rate is controlled, better sensitivity to real contamination is obtained by monitoring fewer well-chosen parameters at a smaller number of well-chosen locations. An evaluation of the proposed revised §264 regulation with respect to these realities reveals that it seems to be a definite improvement over the

SHIPBOARD STOWAGE OF FLAMMABLE AND COMBUSTIBLE LIQUIDS

引用

NAVAL ENGINEERS JOURNAL 1986年第3期98卷 199-208页

作者： DROPIK, MV graduated from the University of Detroit in 1969 with a bachelor of science degree in mechanical engineering. He began his Navy career that year with the Naval Ship Systems Command PMS-382 Ship Acquisition Manager for Mine Patrol and Yardcraft. In 1971 he transferred to the General Arrangements and Habitability Design Branch of the Naval Ship Engineering Center. From 1971–1972 he attended graduate school at the University of California at Berkeley through the Navy's long-term training program and received his master's degree in industrial engineering. He currently heads the Auxiliary/Amphibious/Minecraft/Special Projects Branch of NAVSEA's Arrangements Design Division. His duties in this capacity include those of program manager of the U.S. Navy's flammable liquids program a position which he has held for the last eight years. His experience encompasses the general arrangements habitability storeroom and office design of aviation auxiliary amphibious mine warfare and high performance ships and craft.

The uncontrolled proliferation of flammables and combustibles aboard ship, in addition to posing an obvious fire and explosive hazard, has seriously degraded the survivability and increased the vulnerability characteristics of U.S. Navy surface ships. This problem for the most part has been superficially attributed to a widespread shortage of flammable and combustible stowage capacity. As a result, current solutions have been limited to increasing stowage capacity through additional storerooms and development of more efficient stowage aids. Unfortunately, these solutions simply address the symptoms, are of a corrective nature, and do not eliminate the fundamental causes of the problem. The paper conducts a more systematic and comprehensive investigation into identifying and resolving the flammable liquids problem by considering it from a ship life cycle perspective. In this way, the problem is shown to be the resultant accumulation of a number of causes which occur during a ship's design, construction, and operational phases, and which collectively manifest themselves as a major shortage of flammable and combustible liquid stowage space aboard current fleet ships. Actions are then formulated to eliminate or counteract these fundamental causes, and validated by application to a hypothetical case study.

SHIP ENERGY-CONSERVATION ASSIST TEAM (SECAT)

引用

NAVAL ENGINEERS JOURNAL 1984年第2期96卷 47-58页

作者： DANGEL, R BRICE, AE The Authors A. Edward Brice was born and educated in Scotland where he graduated from the James Watt Memorial College and Paisley Technical College. His earliest marine engineering experience was obtained at Scotts's Shipbuilding and Engineering Company Limited from 1952 to 1959 where he was involved in the production and design of steam and diesel machinery plants for both Naval and commercial ships. During a five year stay in Canada Mr. Brice gained diversified experience in industries other than marine such as petrochemical plants and steel mills. He moved to the U.S. in 1964 where he was the design supervisor in charge of marine engineering at NASSCO covering new construction for American President Lines AFS type ships for the U.S. Navy Project Mohole Car Ferries for the State of Washington and 17 LST's for the U.S. Navy. During the contract definition phase of the DD-963 Mr. Brice authored several portions of the technical proposal while employed by Litton industries. He was also responsible for the system and detail design including the technical management of sub-contracts for the steam propulsion plant for the LHA 1 Class ships. Mr. Brice has been active in the Washington area for the last ten years performing marine engineering projects for the U.S. Navy. His principal interest since 1974 has been in shipboard energy conservation. He assisted in the development of the NavySTMSYS program and later in the operational verification aboard FF-1074. Mr. Brice has conducted four SECA T visits aboard ships with 1200 PSI steam plants and has recently completed an at-sea visit aboard on AOR with a 600 PSI steam plant. Richard Dangel was bom in New York City. He received his Bachelor's degree from the Sloan School of Industrial Management of the Massachusetts Institute of Technology in 1955. He has also completed graduate work for a Masters in Engineering Administration at George Washington University. Since graduation he has spent 11 years in private industry with companies in the DOD engineering research

The Ship Energy Conservation Assist Team (SECAT) program was initiated in Fiscal Year (FY) 82 by the Naval Sea systems Command (NAVSEA) to demonstrate and introduce individual Ship Commands to known energy conserving techniques without adding equipment complexity or additional maintenance burden. The principal objective is to provide each ship with an energy consumption, coupled with recommended energy conservation strategies. The technique involves both in-port and underway monitoring and introduction of energy efficient machinery plant alignments, fuel consumption curve generation, and most efficient speed curves. The program has completed visits on six combatants and enjoys the support of both the Commander, Naval Surface Forces, U.S. Atlantic Fleet (COMNAVSURFLANT) and the Commander-in-Chief, U.S. Atlantic Fleet (CINCLANT). Plans are to perform SECAT on additional DDG 2 and FF 1052/1078 Class ships and initiate SECAT on additional ship types in FY 83.

Proceedings of the 15th conference on Winter simulation - Volume 1

作者： S. J. Deutsch J. E. Richards C. Fernandez-Torres School of Industrial and Systems Engineering Georgia Institute of Technology Atlanta GA Graduate Program in Operations Research N.C. State University Raleigh NC

In this paper, Deutsch, Richards and Fernandez-Torres (1983) fit relaxed time series (RARMA) models to transient and steady state data from a simulated M/M/1 queue and a nonstationary queueing network. Both systems are initially empty and idle. The statistical identification procedure (Richards 1983) for the RARMA model class is illustrated. Improved estimates of the steady state mean of the M/M/1, and of the polynominal in time of the network's nonstationary “steady state” performance, are obtained by including the identified transient model in the RARMA regression.

He worked as a Designer in the Engineering Technical Department of Newport News Shipbuilding and Drydock Co. and he sailed with a number of U.S. flag companies as an Engineering Officer. He joined the Maritime Administration in 1967 and is currently the Assistant for Program Development and Control in the Office of Research and Development. He is a member of ASNE and SNAME. Mr. Ron Corkrey:received B.B.A and M.B.A degrees from the Golden Gate University and was later a guest lecturer there and at other universities. From 1955 to 1969 he held various positions with the Matson Navigation Company ranging from Systems Analyst to Pier Superintendent. From 1969 to 1971 he was the Northern California District Manager for Signal Trucking Service Ltd. He joined the Maritime Administration in 1971 as a Transportation Specialist in the Western Region Office and he is now in Washington D. C. as Program Manager for Cargo Systems R&D. He is a member of the SNAME D31 (Cargo Handling) Panel. Mr. Larry Benen:received his B.S. degree from the U.S. Merchant Marine Academy and a M.S. degree from George Washington University. He is a graduate of the Industrial College of the Armed Forces (ICAF).

He is presently the Program Manager for the Merchant Ship Naval Augmentation Program Exploratory Logistics Experimental Ships and Strategic Sealift Procurement Program.

Projecting our power to far corners of the earth depends on a strategic mobility triad composed of: airlift, prepositioned equipment, and sealift. Airlift can move personnel effectively and limited supplies quickly over great distances. Prepositioned equipment and supplies can extend the effectiveness of those personnel if the circumstances are right, and if we have chosen our positioning sites well. Sealift will provision the lion's share of any protracted engagement, and the ships of the Merchant Marine are a key element in our sealift resources. This paper describes various ways that the Merchant Fleet is being made more responsive to its possible role as a naval auxiliary, and it describes a new concept called SEA SHED which can quickly expand the versatility of Containerships. Containerships have revolutionized marine transportation and they now represent a large and growing portion of the Commercial Fleet. They are limited in the types of cargo they can carry, however, excluding much of the larger equipment required by military units. SEA SHED is a cargo module which fits into the cell guides of a Containership and effectively converts it to a 'tween deck, break-bulk ship which can carry almost all military equipment.

One of the most serious problems encountered in Naval steam plants following World War II was the unreliable performance of boiler and main feedpump pneumatic control systems. In addition to control component and system design deficiencies, these control systems suffered from inadequate methods to measure and adjust system alignment. This paper describes the development of a set of procedures for on-line alignment verification (OLV) of pneumatic main boiler and feedpump control systems. The procedures are designed for use by N avy control system technicians and, in addition to on-line alignment verification, provide guidance for troubleshooting and for performing system alignment. Procedure static checks measure steady state steaming performance and OLV procedure dynamic checks measure the ability of the boiler and control systems to respond to load changes. The paper describes typical control system characteristics that influence OLV procedure content and the supporting analysis that was used to establish alignment criteria ranges that satisfy both steady state and transient performance requirements. Also described is the alignment criteria tolerance analysis along with the steps involved in a typical OLV check procedure development. Descriptions of the various OLV checks, troubleshooting procedures and alignment procedures are provided. Typical shipboard implementation requirements are described and experience to date with the procedures is provided along with a status report on OLV procedure implementations.

The machinery arrangement design process has remained relatively unchanged over the years. Recently, external demands have been placed on both the product and the producers that call for changes to this process. This paper cites these external demands and traces the evolution of the process changes from the rule-of-thumb machinery box sizing routines up to the current automated procedures. The machinery arrangement design practice is presented, and existing analytic and graphics aids are discussed. The user requirements for improved design aids are presented, with implementation guidelines and hardware/software alternatives.
