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.

BAITIS, AEAPPLEBEE, TRMCNAMARA, TMA. Erich Baitis:
a native of Germany came to the David W. Taylor Naval Ship R&D Center in 1957 as a cooperative student/trainee and received his B.S. degree in physics from Virginia Polytechnic Institute. As a 32-year-old naval architect in 1971 he received both the Vietnam Honor Service Medal and the Navy's Meritorious Civilian Service Award for his eight months as liaison with the Vietnamese Navy's ferro-cement program. As head of the Seakeeping and Stabilization Group of the Surface Ship Dynamics Branch his work has led to the development of a new standard Ship Motion Computer Program and the application of ship motions to ship habitability operability and survivability problems. A major area of this work has been the ship-aircraft interface which is particularly sensitive to ship motions wind and other environmental factors. He is a member of the American Society of Naval Engineers and was awarded the Solberg Award for 1982 “in recognition of significant engineering research and development contributions in the area of improved helicopter operations from a ship in a seaway.” Terrence A. Applebee:is currently a naval architect at the David W. Taylor Naval Ship R&D Center in the Surface Ship Dynamics Branch. he came to the Center after earning a B.S. degree in ocean engineering from Florida Institute of Technology in 1973. Since that time
he has worked in the areas of seakeeping performance evaluation ship-helicopter interfacing and human factor considerations. He is a member of the American Society of Naval Engineers and the Society of Naval Architects and Marine Engineers. Thomas M. McNamara:is an employee of the John Hopkins University Applied Physics Laboratory in the ocean data acquisition program. From 1979 to 1983
he worked at David W. Taylor Naval Ship R&D Center in the Surface Ship Dynamics Branch. His expertise has focused on the development of computer models for human factor evaluations as well as motion stabilization systems. He has participated in the development of advanced stabilizat

The FFG 7/LAMPS MK III Operator Guidance Manual (OGM) was developed for all FFG-7 class frigates which are not fin stabilized or are operating with the fins off. The OGM was developed to assis the ship operators of the FFG-7 class in choosing ship speed and heading combinations which will minimize ship motion-related problems during various phases of the LAMPS deployment. Crew safety and performance were major concerns in the development of the OGM. This paper reviews the effect of human factors on ship operations during helicopter recovery, maintenance, and transit to and from the hangar.

A ship design methodology is presented for developing hull forms that attain improved performance in both seakeeping and resistance. Contrary to traditional practice, the methodology starts with developing a seakeeping-optimized hull form without making concessions to other performance considerations, such as resistance. The seakeeping-optimized hull is then modified to improve other performance characteristics without degrading the seakeeping. Presented is a point-design example produced by this methodology. Merits of the methodology and the point design are assessed on the basis of theoretical calculations and model experiments. This methodology is an integral part of the Hull Form Design System (HFDS) being developed for computer-supported naval ship design. The modularized character of HFDS and its application to hull form development are discussed.

During periods of radio silence under Emission Control, communication depends on the slow ship-to-ship, manual-visual, 8-10 wpm Morse code signaling shutter searchlight employing the ac 1000-watt incandescent or the ac 1000-watt compact arc mercury-xenon lamp. These sources can be replaced by the dc compact arc xenon lamp to provide longer daylight ranges and highspeed (100 wpm teletype, 150 wpm Morse code, voice, etc.) communication since this source has superior brightness and the facility of considerably more rapid modulation. The excessive weight and size of the ac-dc power convertor and modulating circuitry which had prevented use of the dc xenon lamp have been overcome by developments in solid state electronics such as the rapid, high current, simmer-flash, 100 to one light output xenon lamp pulsing using the reliable, uncomplicated, low-cost silicon controlled rectifier shunt switch which could eliminate the mechanical signaling shutter. Laboratory and sea evaluations have proved the feasibility of and provided the long daylight high-speed optical communication ranges that could be attained from operation of the dc 1000-watt and 2200-watt xenon lamps at the focus of 12-inch, 18-inch searchlights and in the Fresnel lens omni-directional beacon which a command ship uses to signal all ships in a task force at once. With these advances, optical communication provides the highspeed capability of radio communication, particularly, also, with the new omnidirectional transceiver.
