This paper highlights the survivability concerns in the design of ship service power systems. The paper gives a brief description of what constitutes a typical ship service electric power system and concentrates on electric power generation and associated controls. Established survivability design principles and guidelines are highlighted and the application of those guidelines are discussed. General Specifications (Gen Specs) for Ships of the U.S. Navy are cited as the cornerstone for design. Specific design criteria are cited as well as the rationale associated with the survivability design guidelines pertaining to power generation and distribution. The application of these survivability design guidelines plus the use of the deactivation diagram/damage tolerance analysis cited in the Gen Spec section 072e will enhance overall design and help ensure survivable electric power systems for surface combatants.

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.

DATA MULTIPLEX SYSTEM (DMS) - ASPECTS OF FLEET INTRODUCTION

引用

NAVAL ENGINEERS JOURNAL 1988年第6期100卷 41-47页

作者： BLACKWELL, LM Luther M. Blackwell:is presently the Data Multiplex System (DMS) program manager in the Bridge Control Monitoring and Information Transfer Branch of the Naval Sea Systems Command (NavSea). He graduated from the University of Maryland in 1964 receiving his BS degree in electrical engineering. After graduating he was employed in the Bureau of Ships where he held project engineering assignments on various ships entertainment magnetic tape recording fiber optics computer mass memory and information transfer systems. He has also pursued graduate studies in engineering management at The George Washington University.

The Data Multiplex System (DMS) is a general-purpose information transfer system directed toward fulfilling the internal data intercommunication requirements of a variety of naval combatant ships and submarines in the 1990–2000 time frame. The need for a modern data transfer system of the size and capability of DMS has increased as various digital control systems throughout naval ships have adopted distributed processing architectures and reconfigurable control consoles, and as the quantity of remotely sensed and controlled equipment throughout the ship has increased manyfold over what it was in past designs. Instead of miles of unique cabling that must be specifically designed for each ship, DMS will meet information transfer needs with general-purpose multiplex cable that will be installed according to a standard plan that does not vary with changes to the ship's electronics suite. Perhaps the greatest impact of DMS will be the decoupling of ship subsystems from each other and from the ship. Standard multiplex interfaces will avoid the cost and delay of modifying subsystems to make them compatible. The ability to wire a new ship according to a standard multiplex cable plan, long before the ship subsystems are fully defined, will free both the ship and the subsystems to develop at their own pace, will allow compression of the development schedules, and will provide ships with more advanced subsystems. This paper describes the DMS system as it is currently being introduced into the fleet by the U.S. Navy. The results of its design and implementation in the DDG-51 and LHD-1 class ships are also presented.

The ever increasing complexity of ships coupled with cost, schedule, and resource constraints require innovative methods by the Naval Sea Systems Command's ship design community to meet this challenge. This paper describes the effort by the NavSea Ship Arrangement Design Division to dramatically improve its ship design capability by the use of a system of computer-based design tools called the General Arrangement Design System. The General Arrangement Design System (GADS) is based on the engineering requirements of the ship arrangement design process. GADS is currently being used as a production engineering tool. This paper is organized into two parts. Part I describes the General Arrangement Design System, and Part II describes the general arrangement design methodology.

Ship's propellers are currently measured by manual procedures using pitchometers, templates and gauges. This measurement process is extremely tedious, labor intensive and time consuming. In an effort to provide increased accuracy, repeatability and cost effectiveness in propeller manufacture, an automated propeller optical measurement system (APOMS) has been built which rapidly and automatically scans an entire ship's propeller using a 3-D vision sensor. This equipment is integrated with a propeller robotic automated templating system (PRATS) and the propeller optical finishing system (PROFS) which robotically template and grind the propeller to its final shape, using the APOMS-derived data for control feedback. The optical scanning and the final shape are both controlled by CAD/CAM data files describing the desired propeller shape. An automated propeller balancing system is incorporated into the PROFS equipment. The APOMS/PRATS/PROFS equipment is expected to provide lower propeller manufacturing costs.

Air cushion vehicles (ACVs) have operated successfully on commercial routes for about twenty years. The routes are normally quite short; the craft are equipped with radar and radio navigation aids and maintain continuous contact with their terminals. Navigation of these craft, therefore, does not present any unusual difficulty. The introduction of air cushion vehicles into military service, however, can present a very different picture, especially when external navigation aids are not available and the craft must navigate by dead reckoning. This paper considers the problems involved when navigating a high-speed air cushion vehicle by dead reckoning in conditions of poor visibility. A method is presented to assess the ACV's navigational capability under these circumstances. A figure of merit is used to determine the sensitivity of factors which affect navigation such as the range of visibility, point-to-point distance, speed, turning radius and accuracy of onboard equipment. The method provides simplistic but adequate answers and can be used effectively to compare the-capability and cost of alternative navigation concepts.

In support of the Navy's efforts to improve the energy usage of future ships and thereby to reduce fleet operating costs, a large scale computer model has been developed by the David Taylor Naval Ship Research and Development Center (DTNSRDC) to analyze the performance of shipboard energy systems for applications other than nuclear or oil-fired steam propulsion plants. This paper discusses the applications and utility of this computer program as a performance analysis tool for design of ship machinery systems. The program is a simulation model that performs a complete thermodynamic analysis of a user-specified energy system. It offers considerable flexibility in analyzing a variety of propulsion, electrical, and auxiliary plant configurations through a component building block structure. Component subroutines that model the performance of shipboard equipment such as engines, boilers, generators, and compressors are available from the program library. Component subroutines are selected and linked in the program to model the desired machinery plant functional configurations. The operation of the defined shipboard energy system may then be simulated over a user-specified scenario of temperature, time, and load profiles. The program output furnishes information on component operating characteristics and fuel demands, which allows evaluation of the total system performance.

RATIONALE FOR AN ADA SOFTWARE engineering ENVIRONMENT FOR NAVY MISSION CRITICAL APPLICATIONS

引用

NAVAL ENGINEERS JOURNAL 1984年第4期96卷 133-145页

作者： PAIGE, KK CONVERSE, RA USN LCdr. Kathleen K. Paige USN:graduated with a BA from the University of New Hampshire in 1970. She received her commission from Officer Candidate School in April 1971 and performed her first tour of duty with VFP-63 NAS Miramar. LCdr. Paige then received her MS from the Naval Post Graduate School in June 1976 and returned to San Diego to serve as Head Support Software Division at the Fleet Combat Direction System Support Activity. In May 1981 she reported to NA VSEA (PMS-408) where she served initially as Chairman of the NAVMAT Software Engineering Environment Working Group. She has been assigned as Deputy AN/UYK-43 Acquisition Manager since October 1981. LCdr. Paige was designated a fully qualified Engineering Duty Officer in December 1983. Robert A. Converse:is presently the Acquisition Manager for the Ada Language System/Navy (ALS/N) for the Naval Sea Systems Command Tactical Embedded Computer Resources Project. As such he is responsible for the definition and development of the ALS/N to be provided as a Navy standard computer programming system for Navy mission critical applications. Mr. Converse received a Bachelor of Science degree in Physics from Wheaton College Wheaton II. He spent fourteen years with the Naval Underwater Systems Center Newport Rhode Island during which time he designed and developed the Fortran compiler for the Navy Standard AN/UYK-7 computer. Also during that period he received a Master of Science degree in Computer Science from the University of Rhode Island. His thesis for that degree was entitled “Optimization Techniques for the NUSC Fortran Cross-Compiler”. Mr. Converse started his involvement with the Ada program in 1975 with the initial “Strawman” requirements review. Subsequently he was named as the Navy Ada Distinguished Reviewer and was intimately involved in the selection and refinement of the Ada language as it evolved to become ANSI/MIL-STD-1815A.

The U.S. Navy introduced the use of digital computers in mission critical applications over a quarter of a century ago. Today, virtually every system in the current and planned Navy inventory makes extensive use of computer technology. computers embedded in mission critical Navy systems are integral to our strategic and tactical defense capabilities. Thus, the military power of the U.S. Navy is inextricably tied to the use of programmable digital computers. The computer program is the essential element that embodies the system “intelligence”. In addition, it provides the flexibility to respond to changing threats and requirements. However, this very flexibility and capability poses a host of difficulties hindering full realization of the advantages. This paper describes the lessons learned about computer program development over the past twenty five years and discusses a software engineering process that addresses these lessons. It then describes how Ada and its related Ada programming Support and Run-Time Environments foster this software engineering process to improve computer program productivity and achieve greater system reliability and adaptibility. Finally, the paper discusses how the use of Ada and its environments can enhance the interoperability and transferability of computer programs among Navy projects and significantly reduce overall life cycle costs for Navy mission critical computer programs.
