In this paper, a methodology and guidelines for applying risk methods in design and operation of maritime systems were developed and demonstrated using a case study of marine diesel generators. The methodology consists of several modules that include system definition based on functional and performance requirements, definition of dependencies among subsystems, data collection and reduction, reliability and risk analyses, and results reduction for use in decision analysis. The methodology was used to assess and analyze typical service diesel generators found onboard ships. The analysis included the generation of cut sets for the overall reliability of the system. The most likely failure scenarios were determined by demonstration as the failure of fuel supply components. The results are consistent with previous findings of the U.S. Coast Guard.

His last duty station was NAVCOMSTA Roosevelt Road Puerto Rico where he sewed as muster chief-in-charge of electronic communications repair the island-wide communications quality control chiel the contract administrator to the operations and maintenance contractor supporting Mystic Star transmitter and receiver facilities for Air Fme One communications the Naval transmitter station and 16 interconnecting remote mimowave sites. Wilhemina C. Greene is a Supervisory Electronics Engineer with the Combatant Engineering and Integration Section at NAWCAD. As the team leader directs the effots of Civilian and contractors personnel responsible for delivering a fully integrated and tested Radio Communication Systems for surfme cmnbatant ships. The team also pvovida the Nay's only system level training on RCS for all AEGIS Pre-Communits. As part ofthis eflort she is responsible for the operation and maintenance of the Satellite Production Test Centq a facility housing the RCS test beds. Ms. Greene has over 20 years of government service 13 years on the AEGIS RCS program. She has a BSEE degree from Tennessee State University.

As shipboard radio communication systems (RCSs) become more complex and crew size continues to be reduced, the requirement for an automated, condition-based maintenance system is imperative. Personal computers can be programmed to provide full equipment testing that is capable of digital interface as well as automated and semi-automated testing of equipment that is not buss-controllable. Some of the advantages of computer-controlled equipment testing (CCET) include increased accuracy repeatability, and data-collection capability for in-depth analysis. However, the paramount advantage of CCET is speed. This paper will describe various methods of remote testing, including using a LAN, the Internet, and the telephone system. It will detail application software developed to test the Aegis-class destroyers' RCS equipment. This paper examines CCET as it is presently applied to the Aegis Board of Inspection and Survey (INSURV) support program. Additionally, the condition-based maintenance (CBM) application developed for over-the-air system testing of the Navy's UHF line-of-sight (LOS) system installed on the USS Yorktown (CG 48) as part of the Smart Ship project will be described. This paper will also describe CCET methods to use charged-coupled device (CCD) miniature cameras to read analog meters, gauges, or entire gauge boards.

Ship design is often multidisciplinary involving several design elements with various types of objectives and constraints (O/C) some easily described as mathematical formulas, others better modeled as descriptive assertions. This paper describes a method based on fuzzy functions and an integrated performance index to model O/C using descriptive assertions to be used with mathematical formulas in optimization. Another issue addressed in this paper concerns the coordination of design elements when sequentially coupled, that is, when one leads the other and the performance of the follower depends greatly on the design of the leader. Based on neuro-fuzzy techniques, the method described here coordinates and optimizes sequentially coupled elements. The two methods are applied to machinery arrangement (MA) and pipe routing (PR). Preliminary models for optimization of MA and PR are described considering convenience, producibility: engine room size, interference and location as factors in the O/C set. Some test results from MA/PR applications are presented and discussed. The methods are generic and can be extended to other elements in ship design. They are mutually independent and may be used separately Two advantages of their use are an improvement in overall performance and a reduction in the need for redesign of elements.

Ground Water Solutions Inc. specializes in the facilitation and management of projects involving subsurface contamination. Other services include analysis and communication of ground water issues peer review and litigation support. Roy O. Ball P.E. Ph.D. received his B.S. in civil engineering from the University of Florida his M.S. in environmental health engineering from the University of Texas at Austin and his Ph.D. in environmental engineering from the University of Delaware. He is a registered professional engineer in Delaware Illinois Indiana Minnesota and Wisconsin. Dr. Ball is currently a principal of ENVIRON International Corp. (750 W. Lake Cook Rd. Ste. 420 Buffalo Grove IL 60089 520–1155 520–9490) in Chicago. He has more than 25 years experience in environmental engineering and consulting primarily for industry. Dr. Ball directs numerous RI/FS and remediation activities at Superfund RCRA Corrective Action and Voluntary Cleanup Program Sites.

The closure of sites with identified or suspected DNAPL (dense nonaqueous phase liquids) under the requirements of the Resources Conservation and Recovery Act of 1976 (RCRA), or the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (CERCLA) has not been well defined. With respect to RCRA, the U.S. Environmental Protection Agency (EPA) has required that all contamination must be removed at closure such that no residual risk to human health or the environment remains. Therefore, even though many states administering the RCRA program have adopted or are considering Risk-Based Corrective Action (RBCA) procedures (including the statistical methods described in SW-846) for RCRA closure, the treatment of DNAPL is, at best, challenging. The methodology for closure in CERCLA is described in “Risk Assessment Guidelines for Super-fund (RAGS),” which requires that risks above the National Contingency Plan criteria must be remediated, preferably by on-site or in situ destruction. Most risk-based Brownfield or voluntary cleanup programs do not provide any explicit allowance for DNAPL. However, while the ASTM methodology for RBCA in E1739-95 (ASTM 1995) does not explicitly treat the problem of DNAPL, a basic framework for DNAPL assessment is implicitly provided. A uniform methodology for RBCA closure of VOC (volatile organic compounds) DNAPL sites can be used to achieve the program objectives of RCRA, CERCLA, and Brownfield or voluntary cleanup programs. The regulatory acceptance of the application of RBCA methods to DNAPL sites will require education and discussion, but the use of a uniform methodology should facilitate acceptance.

作者： D.L. Forkey W.D. Smith R. Berguer Biomedical Engineering Program California State University Sacramento CA USA School of Medicine and VA Northern California Health Care System University of California슠Davis Martinez CA USA

Processed electromyogram (EMG) signals were acquired from 27 subjects while they completed two simulated surgical tasks using first a hemostat, and then an Ethicon/sup (R)/ laparoscopic grasper, with the aid of an endoscopic trainer and video monitoring system. The two tasks were: opening and closing alligator clips, and peeling apart two pieces of Velcro/sup (R)/. Three indices (peak processed EMG, average processed EMG and integrated effort-area under the processed EMG vs. time graph) were used to indicate the physical workload placed on the surgeon during laparoscopic and open surgery. It was found that the indices were significantly (P<0.05) greater for both tasks performed using laparoscopic as opposed to open surgery techniques. These findings indicate that performing tasks using laparoscopic surgical techniques is more taxing on the surgeon.

Despite the limits inherent within linearized frequency-domain ship motion and wave load computer codes, strip theory has been found to provide the design community with a fairly robust, practical design tool with reasonable accuracy for most conventional displacement monohulls. However, the advent of new design concepts including multi-hulls and application of new materials as well as the push to incorporate reliability methods within surface ship structural design criteria has highlighted the need for more rigorous methods of developing a lifetime load spectrum. In this paper, a multilevel computation system for predicting ship motions and wave loads, up through and including extreme sea conditions, is presented. This system includes a traditional strip theory approach and newly developed linear and nonlinear three-dimensional time-domain methods. The new nonlinear methods are currently in the process of being validated by the U.S. Navy. The status of the current development is presented. Sample numerical results from the new nonlinear methods are compared with both linear frequency domain predictions and model tests.
