作者： KEHOE, JW BROWER, KS TUTTLE, JG Capt. James W. Kehoe Jr. USN (Ret.):is well known for his work in comparative naval architecture studies of U.S. and foreign warship design practices for which he received the American Society of Naval Engineer's Gold Medal Award for 1981 and the Legion of Merit in 1982. He received the ASNE “Jimmie” Hamilton Award for 1983. He is currently a partner in Spectrum Associates Inc. Arlington Virginia. Prior to his retirement in 1982 his naval career included sea duty aboard three destroyers and three aircraft carriers including command of a destroyer and engineer officer of an aircraft carrier. Kenneth S. Brower:is a partner in Spectrum Associates Inc. a naval engineering firm which he founded in 1978 which is currently engaged in the design of naval ships comparative naval architecture studies and the development of ship design synthesis computer programs. A graduate in naval architecture from the University of Michigan he has contributed to the design of numerous warships and merchant ships as well as several frigate designs for foreign military sales. Mr. Brower has been the author or coauthor of numerous technical studies and articles. He received the ASNE “Jimmie” Hamilton Award for 1983. LCdr. John G. Tuttle USCG:is a graduate of the New York Maritime College and the Naval Construction and Engineering Program at MIT. Prior to joining the Coast Guard he was a naval architect for the Navy. He has served in the Marine Safety Offices in New Orleans and Boston. He has also been an instructor in the marine engineering program at the Coast Guard Academy. He was a project officer in the Office of R&D supporting buoy tender and patrol boat acquisitions. He is currently assigned as technical manager of the Buoy Tender Replacement Project in the Office of Acquisition at USCG Headquarters.

The paper reports the results of a comparative study of seven modern foreign buoy tenders and two older U.S. buoy tenders that was conducted by the U.S. Coast Guard as part of its current project to replace its older medium size (WLM) and large seagoing (WLB) buoy tenders. As part of the assessment, the authors visited the foreign ships to observe them conducting buoy tending operations, to review engineering design data, and to discuss buoy tender design, technology and operations with the cognizant operating authorities. The buoy tenders included the Canadian 4,800-ton Type 1100 and 2,800-ton Type 1050, the British 2,900-ton Mermaid , the Swedish 1,200-ton Baltica , the Norwegian 1,100-ton Skomvaer , the Dutch 700-ton Rotterdam , and the Italian 600-ton MIF. The U.S. buoy tenders included the Coast Guard 470-ton, 157-foot WLM and 1,000-ton, 180-foot WLB (SLEP), which were also visited and included in the study for comparative purposes. The study's objectives were to identify design practices and technology incorporated in the foreign buoy tenders that the U.S. Coast Guard could adapt in designing future buoy tenders and to determine if any foreign buoy tender design meets the Coast Guard requirements for WLB and WLM replacements. The design characteristics, technology, and unique features of each buoy tender are described and compared. Lessons learned from the study which could be beneficial in the design of future Coast Guard buoy tenders are identified. Finally, the capabilities of the foreign buoy tenders are assessed in relation to current Coast Guard requirements.

The major objective of this paper is to describe a computer aided methodology for structural integration and analysis. Using the example of recent work in the installation of modular gun and vertical launch missile systems in warships, the reader is guided through a typical case of computer aided structural design and shock analysis, how the models are defined and tested, how the models are modified in order to be compatible with computer capacity, how structural elements are selected to simplify computations, and finally how the results of these operations are used to define the final product before construction and installation. With the maturation of the computer aided process as applied to the whole ship product, more attention must be focused on improving the individual elements of computer aided design (CAD), computer aided engineering (CAE) and computer aided manufacturing (CAM) and the integration of these processes and their products through computer integrated manufacturing (CIM). The application of the CAE techniques described herein to large maritime systems such as combatant, auxiliary and support, and commercial ships and to other large structures such as semisubmersible and fixed platforms is powerful and highly in demand. There is now a means to optimize large structural systems in terms of their discrete subsystems and components and harmonize the entire design while providing the proper design integrity at each successive level of detail.

Anticipated technological advances in the quieting of potential adversary submarines mandate the use of increasingly effective detection systems for U.S. ASW forces. Based on the assumptions that sonar will continue to be the primary means of detection and that the effectiveness of each individual sonar element will not change markedly, one must increase the projected area of the sonar array to improve its capability. The primary SSN mission of anti-submarine warfare will hence require increasing the hull area devoted to the primary sonar detection system. A revolutionary hull form is proposed that maximizes the area available for this purpose. The advantages and disadvantages of this hull form are discussed and feasibility study level design parameters and arrangements presented.

Some fairly radical changes to the naval ship design process occurred during the 1970s. The decade of the 80s has also witnessed a steady stream of changes. One of the most significant was the establishment of the Ship Characteristics Improvement Board (SCIB) in the Office of the Chief of naval Operations (OpNav), and the resulting influence on the dialog between the military requirements decision makers and the Navy's ship designers. Other changes have occurred for which the impacts are less clear. These include establishment of the chief engineer of the Navy (ChEng) position, creation of the Space and naval Warfare Systems Command (SpaWar) and OpNav's “Revolution at Sea” initiative. This paper will describe and discuss these and other changes, and comment on the resultant impact. The authors will attempt to present a global view of the total pattern of changes and try to discern if we are on a path of revolution, or merely normal evolution.

He has worked with the Bechtel Professional Corporation the David Taylor Naval Ship Research and Development Center and the United States Coast Guard. He is a member of SNAME ASNE ABYC and IMTI. He is the author of “Reaction Fin Applications In Marine Propulsion” which documented the use of asymmetric pre-swirl vanes to increase propulsion efficiency aboard a 41-ft Coast Guard utility boat. It was presented on 5 March 1987 at the Hampton Roads section of SNAME and was nominated for the section paper of the year award. CWO3 Joe Bobby McCollum USCG: iscurrently engineering officer of the Surface Effect Ship Division Seventh Coast Guard District Key West Florida. Prior to this assignment he was assistant engineering officer on the USCGCUte.His other duty tours included engineering assignments on theCape Currenta 95-foot patrol boat on the USCGCUnimak a 311-foot cutter CG Loran Station Upolo Point Hawaii and CG Station Sabine Pass Texas. CWO McCollum was responsible for modifying and repairing the SESs and contributed many unique problem solving ideas which resulted in much improved operation of the Coast Guard Surface Effect Ship Division. Benton H. Schaub:is a senior engineer with Maritime Dynamics Inc. He has a bachelor of science degree in naval architecture and marine engineering from the Massachusetts Institute of Technology. Mr. Schaub has fifteen years of experience working as a test engineer project engineer and design engineer on advanced marine vehicle projects and is a recognized authority in the areas of hull structure seal system and machinery design for surface effect ships.

He is currently responsible for performing detailed design and analysis in support of the seal system for the Germa

During the early 1980s the United States Coast Guard took delivery of three surface effect ships (SES) from Bell Halter, Inc. These 136-ton, 30-knot plus, aluminum hulled cutters were to be used primarily for drug interdiction in the southeastern United States. By early 1985, however, the full load weight of these cutters had grown to 150 long tons, and their top speed had dropped to below 23 knots in calm water. By mid-1985, operation of all three SESs was suspended to prevent possible catastrophic failure of their main engines. At this point, the USCG joined ranks with Textron marine Systems (then Bell Aerospace), and Detroit Diesel to analyze what had gone wrong, and to propose solutions to the problems encountered. From that beginning, the performance of the Coast Guard's SESs has steadily and dramatically improved until at present all three cutters are able to exceed their original performance specifications. This paper discusses the problems experienced with the SESs, including engine overloading, vibration, ride quality, seal wear, poor lift system performance, and metal cracking, along with the corrective actions taken to solve them. The cooperation between government and private industry, which made this dramatic turn-around in performance possible, is also explored. Lessons learned about SES technology are viewed in relation to the general experience of the Coast Guard with other types of high performance hull forms.

naval ENGINEERS JOURNAL 1988年第6期100卷 59-71页

作者： KOLESER, J LAVIS, DR Jeffrey Koleser:was educated at the University of Michigan where in 1980 he earned his BSE in naval architecture and marine engineering. His professional career began with Gibbs & Cox Inc. New York City where he worked on the FFG-7 class ships for the U.S. Royal Australian and Spanish navies. In 1982 Mr. Koleser joined the Naval Sea Systems Command in the Preliminary Design Section (SEA-501) where he works today. Since then he has worked on the contract design of the DDG-51 the NFR-90 the Warfighting Improvement Program for the BB-61 class the FFG-7 class and the FF-1052 class ships. He has also worked on several CONFORM projects including the Arctic ACV. In addition to Mr. Koleser's formal education at the University of Michigan he is presently finishing up his studies at the off campus seminar of the Naval War College. David Lavis:was educated in Exmouth and Exeter Devon England. He began his professional career in air cushion vehicles with Saunders-Roe on the Isle of Wight in 1959. Initially as a student apprentice Mr. Lavis worked on many aspects of air cushion vehicle research design and construction. In 1966 he received a master of science degree from Cranfield Institute of Technology. A year later he joined Bell Aerosystems Buffalo New York and was engaged in the early design work for the SES-100B and the AALC Jeff(B). Mr. Lavis then joined the Aerojet General Corporation (AGC) in Sacramento and in 1972 he was appointed manager of technology for the AGC SES Division who were at that time testing the SES-100A and conducting the early design work for the 2KSES and AALC Jeff(A). Mr. Lavis has continued to support the U.S. Navy advanced ship programs. In 1977 together with Mr. E. G. U. Band he formed Band Lavis & Associates Inc. of Severna Park Maryland a company specializing in advanced marine technology.

The paper presents the results of the NavSea FY8S Surface Ship CONFORM Design Study for an initial operational capability (IOC) year-2000 air cushion vehicle (ACV) suitable for logistics and for general search and rescue duties in the Arctic. The study is one of several design studies produced each year by the CONFORM program to provide OpNav with alternative feasible ship concepts for varying IOC dates and to provide R&D planners with feedback regarding R&D alternatives. Two complete feasibility designs were developed. The first design was developed with the aid of an ACV design synthesis math model. The second design evolved as a derivative of an existing U.S. production craft and, as such, offered a lower risk approach. The results of performance and cost trade-off studies are presented from which it is concluded that gas turbines are the preferred choice of power plants and aluminum alloy is the preferred choice of hull structural material. The most suitable skirt height was found to be approximately 12 ft.

作者： OREM, JB The authoris currently group technical director at Advanced Technology Inc. where he is engaged in system engineering and ship design programs. A graduate of the U.S. Naval Academy in 1951 he served in various surface assignments until attending MIT in 1955. Subsequent to becoming an engineering duty officer he served in naval shipyards afloat engineering ship design and fleet ship salvage billets. He directed the preliminary design of FFG-7 and later served as project technical director. Subsequent tours included duty as project manager nuclear cruiser acquisitions and assistant to the deputy under secretary of defense (acquisition). Upon retirement he joined Sun Shipbuilding and Dry dock Company serving as V. P. program management and V. P. engineering. His education includes a B. S. from the U.S. Naval Academy and an M. S. in naval architecture and marine engineering and a naval engineer's degree from MIT in 1958.

In recent years, the expanding use of electromagnetic systems in warships has created significant problems. Mutually antagonistic systems degrade intended performance and serious safety problems have been created. The environmental effects produced by these systems must be considered in the mainstream of the warship design process. Systems engineering considerations using specific examples will show the potential impact on warship design considerations not normally considered. In addition, electromagnetic engineering considerations are proposed for impact on specific ship specification sections.
