SHIPBOARD STOWAGE OF FLAMMABLE AND COMBUSTIBLE LIQUIDS

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.

Robust ship AAW defense capability is a priority requirement that enables Naval Forces to conduct joint expeditionary force operations in littoral environments. As an aid to achieving this capability for all ship classes, the Navy has reorganized its management of ship defense. A major focus of these efforts is the development of a fully automatic, integrated combat system for non-Aegis ships which is based on coordinated detection, control, and hard kill/electronic warfare (HK/EW) engagement functions. A phased approach to attaining this fully integrated capability has been established which includes major element upgrade introduction when technology and budget permit. This paper describes the ship self-defense performance assessment methodology which has been adopted to support the review and decision process for future planning and budgeting. This process is a continuation and refinement of that used to provide data for the Office of the Secretary of Defense Fall 1991 Conventional systems Committee Ship Self-Defense Review. The performance assessment methodology starts with definition of survivability requirements by ship class, combat system configurations, Anti-Ship Missile threat, and operational scenario. Viable self-defense system element options are then identified. The capability of these options are then characterized for input into ship level performance prediction models. Three partitions of performance prediction modeling are made: hard kill elements only, electronic warfare element only, and integrated HK/EW. The most significant accomplishment of this effort, beyond providing data to support programmatic decision, has been the creation of a truly integrated HK/EW surface ship combat system model that interleaves HK and EW timelines and allows parametric variation to evaluate options. Because of classification, only generic examples of numerical result will be presented. However, the procedures for establishing the modelling process, prioritization of

IOP Conference Series: Materials Science and engineering 2019年第1期598卷

作者： R Yusianto Marimin Suprihatin H Hardjomidjojo Graduate Program of Agro-Industrial Technology Bogor Agricultural University (IPB) Bogor Indonesia Department of Agro-Industrial Technology Faculty of Agricultural Technology Bogor Agricultural University (IPB) Bogor Indonesia Division of Industrial and Systems Engineering (TSI) Bogor Agricultural University (IPB) Bogor Indonesia

The demand for alternative sources of fossil fuel energy in Indonesia is increasing. One alternative to fossil fuels is bioethanol. Potato skin starch can be a raw material for making bioethanol. Potato skin contains starch, cellulose, hemicellulose, lignin and sugar. Bioethanol can be used must go through several stages, including the logistics system. Logistics activities require transportation, material handling equipment, and warehouses. In Indonesia, transportation sector which is the biggest user of fuel actually receives fuel subsidies. Bioethanol is the most appropriate alternative solution to replace gasoline. In processing, bioethanol through five stages, namely, potato skin starch, raw material logistics, processing bioethanol, delivery process and customer. This study presents green logistics model of potato transportation with a cost model and GWP. The results of the study show that the green logistics model by looking at the total costs and environmental impacts can be used as a reference in developing environmentally friendly bioethanol production in the future.

Navy ships must be able to operate anywhere in the world and visit any port unencumbered by environmental restrictions. The Office of the Chief of Naval Operations (OCNO) has formulated a vision for the environmentally sound ship of the 21st century, which will ensure compliance with environmental requirements applicable to Navy ships, while maintaining fleet effectiveness and readiness. Navy ships generate a variety of solid and liquid wastes and atmospheric emissions. Ships have limited capabilities for holding wastes for offload to shore. Working closely with the OCNO, the Naval Sea systems Command (NavSea) is developing systems, equipment, and procedures to process and manage ship wastes in an environmentally responsible manner. Several pieces of shipboard equipment have been successfully developed to process solid and liquid waste, hazardous materials and ozone-depleting substances (ODSs). The technologies and practices being developed under this program will: ensure compliance with environmental laws and regulations, significantly reduce the logistic burdens and costs associated with shoreside offload and disposal of ship wastes, implement Navy environmental and occupational safety and health policies, enhance the quality of life aboard ship, and continue the Navy's leadership role in protecting the marine environment.

Humans rely increasingly on sensors to address grand challenges and to improve quality of life in the era of digitalization and big data. For ubiquitous sensing, flexible sensors are developed to overcome the limitations of conventional rigid counterparts. Despite rapid advancement in bench-side research over the last decade, the market adoption of flexible sensors remains limited. To ease and to expedite their deployment, here, we identify bottlenecks hindering the maturation of flexible sensors and propose promising solutions. We first analyze continued...challenges in achieving satisfactory sensing performance for real-world applications and then summarize issues in compatible sensor-biology interfaces, followed by brief discussions on powering and connecting sensor networks. Issues en route to commercialization and for sustainable growth of the sector are also analyzed, highlighting environmental concerns and emphasizing nontechnical issues such as business, regulatory, and ethical considerations. Additionally, we look at future intelligent flexible sensors. In proposing a comprehensive roadmap, we hope to steer research efforts towards common goals and to guide coordinated development strategies from disparate communities. Through such collaborative

Advances in aircraft carrier life cycle cost analysis for acquisition and ownership decision-making

引用

NAVAL ENGINEERS JOURNAL 2000年第3期112卷 97-110页

作者： Chewning, IM Moretto, SJ Irvin M. Chewning:is currently the Director of the Aircraft Carrier Cost Estimating and Industrial Analysis Group of the Naval Sea Systems Command. Over the past four years Mr. Chewning has guided the cost analysis effort for the new CVNX class aircraft carrier through a three-part analysis of alternatives and is currently steering it towards Milestone I in June of 2000. In 1999 the CVNX cost analysis team was presented the NAVSEA Association of Scientists and Engineers “outstanding team achievement” award for its work on the CVNX analysis of alternatives. Mr. Chewning's professional career includes over 16 years as an employee of Newport News Shipbuilding as a Pipe Fitter Piping Systems Designer Piping Systems Engineer and Cost Engineer. He has worked at the Naval Sea Systems Command since 1980 as a Senior Cost Analyst Branch Head and Deputy Division Director of the Cost Estimating and Analysis Division. He has preformed cost analysis work for virtually all USN combatant programs including submarines cruisers destroyers frigates and aircraft carriers. He also performed the cost analysis work for the OSD evaluation of the Israeli Naval Modernization Program in the 1980's. Mr. Chewning is also Chairman of the NATO Specialist Team on Ship Costing a subgroup of the NATO Naval Group Six on Ship Design. Under his leadership two Allied Naval Engineering Publications have been completed in the 1990's: ANEP-41 on Ship Costing and ANEP-49 on Ways to Reduce Costs of Ships. In 1999 the NATO Specialist Team on Ship Costing completed a paper titled “Manpower Reduction and the Use of Commercial Standards and Practices to Reduce Costs of Ships.” The result of this work will be incorporated in a future revision of the aforementioned ANEFs. Mr. Chewning is a graduate of North Carolina State University with a Bachelor of Science in Mechanical Engineering. Mr. Chewning has also completed courses at the University of Virginia and Christopher Newport University Mr. Chewning is a graduate of the Program Management College

The U.S. Navy recently conducted an analysis of alternatives (AOA) to set the stage for determining the characteristics and acquisition strategy for its next generation aircraft carrier. The platform design selected is expected to be in service throughout the 21st century. The parameters under consideration for change in the new carrier design lie in the areas of propulsion and electric power generation, aviation, survivability, service life, and total ownership cost (TOC) reduction. The issue of affordability is paramount This paper focuses on the need for the program management office and its supporting cost analysis staff to understand the life cycle cost (LCC) of the existing and proposed future aircraft carriers and to then translate these LCC's into meaningful information for cost-conscious decision making. The challenge is to relate the LCC in terms the key decision-makers and the engineering team can use to satisfy their respective roles. Thus, it is necessary to translate the results of the given ship design alternative LCC's into the paradigms of the respective stakeholders: Fleet User (operators of aircraft carriers) Ship Designers (translators of the fleet operator requirements) program Sponsors (providers of the funding resources) program Management Office, Ship builder and Supporting Industry (executors of the acquisition and construction of the ship) Navy and OSD decision-makers (overseers of program execution) The paper describes the aircraft carrier LCC breakdown structure that has resulted, in part, from a recent navy/shipbuilder integrated product team effort to capture total ownership costs. The structure has been used in the AOA as a tool to identify cost drivers and to add the time element to the cast equation in order to perform return on investment and program affordability analysis. The expanded ship work breakdown structure (ESWBS) has emerged as the central backbone of the cost work breakdown for AOA work. The ESWBS structure is a natural

IOP Conference Series: Earth and Environmental Science 2021年第1期729卷

作者： F E Gunawan Y Kanto I Kamil Sutikno H N Tran Industrial Engineering Department BINUS Graduate Program - Master of Industrial Engineering Bina Nusantara University Jakarta Indonesia 11480 Mechanical Systems Engineering College of Engineering Ibaraki University Ibaraki Japan Department of Industrial Engineering Department Faculty of Engineering Andalas University Padang Indonesia Department of Mechanical Engineering Department Faculty of Engineering Institut Teknologi Sepuluh Nopember Surabaya Indonesia Department of Automotive Engineering Faculty of Transportation Engineering Ho Chi Minh City University of Technology Ho Chi Minh City Viet Nam

Structural Health Monitoring (SHM) system can be considered as an Internet-of-Things (IoT) system implemented to engineering structure to provide real-time information on the integrity of the structure. In doing so, the system acquires data from various sensors distributed across the structure and infers damage sensitive quantities. In the research, we proposed a damage index derived from the governing dynamics of the structure in the frequency domain. The proposal was empirically verified by applying the index to analyze the case of a cracked cantilever beam subjected to a harmonic load. The value of the damage index was computed at some points surrounding the crack to understand the effect of the distance of the monitoring point to the crack to the index sensitivity. The results suggest that the index is sensitive to the crack particularly when the observation point is near the crack.

The necessity to efficiently balance and re-allocate system resources among hospitals in a hospital network is paramount, especially as health systems experience increasing demand and costs for health services. In this paper, we proffer a resource allocation-based optimization model that adjusts resources (system inputs) automatically, which provides decision makers (such as health care managers and policy-makers) with a decision-support tool for re-allocating resources in large health systems that are centrally controlled and funded, such as the Military Health System. In these systems, inputs are fixed at certain levels and may only be adjusted within medical treatment facilities, while outputs must be maintained. We provide a mathematical formulation and example solutions from a case study using real-world data from sixteen U.S. Army hospitals. We also find utility in the use of multi-start evolutionary algorithms to store multiple optimal solutions for consideration by decision makers. © 2014 "IIE".
