CONCEPT study OF MOBILIZATION TUG-BARGE DESIGNS

naval ENGINEERS JOURNAL 1980年第2期92卷 23-33页

作者： WILSON, WB FOLTIS, C Mr. Warren B. Wilson received his B.S. degree in Naval Architecture and Marine Engineering from Webb Institute in 1975. and in 1976 was awarded the SNAME Wilbur N. Landers graduate scholarship for study at Massachusetts Institute of Technology subsequently receiving his M.S. degree in Naval Architecture and Marine Engineering in 1977. Following his graduation from Webb Institute he was employed by the Naval Ship Engineering Center (NAVSEC) in the Hull Division where he worked on Submarine arrangements in the Ship Arrangements Branch and was the Hydrodynamics Task Leader for the T-ARC Cableship in the Hull Form and Hydrodynamics Branch. At the present time. he is a Naval Architect at the Maritime Administration (MARAD) where he has been involved most recently in MARAD's T-AO Concept Design effort. Mr. Wilson is an Associate Member of SNAME and in 1975 was the recipient of SNAMES Undergraduate Paper Award. Mr. Constantine Foltis received his B.S. degree in Naval Architecture and Marine Engineering from the University of Michigan in 1953. He worked for short periods of time for Carl J. Nordstrom. Consulting Architect in Seattle. Wash. and for M. Rosenblatt & Son. Inc. New York City. prior to joining the Maritime Administration in 1955. Since then he has held a variety of naval architectural positions in and out of the MARAD Washington Headquarters. Currently. he is the Manager of Preliminary Design in the Division of Naval Architecture and in this capacity supervises the preparation of concept studies and preliminary designs of a wide variety of Merchant Ships and Barges of all types. both for new construction and conversion. Mr. Foltis is a registered Professional Engineer in the state of Maryland. and in addition to ASNE. which he joined in 1977 is a member of SNAME.

This paper describes one facet of a continuing effort within the Maritime Administration to insure the adequacy of the United States Merchant marine in a war or national emergency. As a result of comments on “Merchant Ships for Wartime Mobilization Prototype Design and Construction for Readiness”, given at ASNE Day 1976, a concept study was initiated within the Maritime Administration to assess the utility of integrated Tug-Barges in a mobilization program. The results of this study are given in this paper. In light of the restricted number of shipways available for building the multi-purpose mobilization ship, the need is defined for another ship type which would be suitable for construction at a larger number of facilities. General design objectives are then developed for this ancillary ship which satisfy mobilization requirements. A brief analysis of the capability of integrated Tug-Barges to meet the design objectives is conducted, followed by four Barge concept designs and a description of Tug options, which demonstrate the feasibility of utilizing Tug-Barges in a mobilization effort. The eventual goal, after the completion of a preliminary design phase, will be the development of a set of contract plans and specifications followed by the construction of a prototype vessel.

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.

Economic Feasibility of a Small-Scale Wind Turbine in Coastal Area of South Sulawesi

引用

IOP Conference Series: Earth and Environmental Science 2021年第1期921卷

作者： F Mahmuddin N Puspitasari M U Pawara Marine Engineering Department Engineering Faculty Hasanuddin University Indonesia Naval Architecture Program Department of Science Food Technology and Maritime Kalimantan Institute of Technology Balikpapan Indonesia

To evaluate the exploitation potential of wind energy in the coastal area of South Sulawesi, Indonesia, an investigation on the economic feasibility of this project was performed. A 300-watt horizontal wind turbine was used as an example installed turbine. The wind speed range of 4-7 m/s which was the wind speed data in the coastal area of South Sulawesi was computed. The main economic analysis method employed was Capital Budgeting Analysis (CBA) method. In this method, 4 (four) indicators were used to evaluate the feasibility of the project which are payback period (PBP), net present value (NPV), internal rate of return (IRR), and benefit-cost ratio (BCR). A visual basic computer program based on the CBA method was also developed to make the computation more convenient. From the study, it was found that the wind speed range of 4-6 m/s resulted in a non-feasibility project while the highest wind speed (7 m/s) was found to be quite strong to make the project feasible.

Patterns of avoidance, adjacency, and association in complex systems design emerge from the system’s underlying logical architecture (functional relationships among components) and physical architecture (component physical properties and spatial location). Understanding the physical–logical architecture interplay that gives rise to patterns of arrangement requires a quantitative approach that bridges both descriptions. Here, we show that statistical physics reveals patterns of avoidance, adjacency, and association across sets of complex, distributed system design solutions. Using an example arrangement problem and tensor network methods, we identify several phenomena in complex systems design, including placement symmetry breaking, propagating correlation, and emergent localization. Our approach generalizes straightforwardly to a broad range of complex systems design settings where it can provide a platform for investigating basic design phenomena. Copyright © 2020, The Authors.

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.

Preliminary design of 5 GT fishing boat with electric motor propulsion for daily coast fisherman

引用

AIP Conference Proceedings 2024年第1期2710卷

作者： Muhammad Arif Budiyanto Muhamad Adnan Sriyadi Department of Mechanical Engineering Universitas Indonesia Depok Jawa Barat Indonesia Undergraduate Program of Naval Architecture and Marine Engineering Department of Mechanical Engineering Universitas Indonesia Depok Jawa Barat Indonesia

Indonesia is an archipelagic country with a large number of daily coastal fishermen. The majority of fishing boats use diesel as fuel, on the other hand, solar energy as a renewable energy source is widely available in countries that cross the equator. This paper aims to conduct a preliminary design of a 5 GT fishing boat’s use of solar panels as electric motor propulsion for daily coast fishermen. Based on field data processing, it was found that the appropriate fishing boat size was 10 m in length, 2.2 m in width, 1.1 m in height, and 0.55 m in the draft. The results of the design show that the electric motor propulsion fishing boat can operate optimally using solar energy is 7 hours with a sailing distance of 9 sea miles. These results can be used as a reference for the substitution of fossil fuels into renewable energy so that they can provide the benefits of low daily operating costs for daily coast fishermen.

The machinery arrangement design process has remained relatively unchanged over the years. Recently, external demands have been placed on both the product and the producers that call for changes to this process. This paper cites these external demands and traces the evolution of the process changes from the rule-of-thumb machinery box sizing routines up to the current automated procedures. The machinery arrangement design practice is presented, and existing analytic and graphics aids are discussed. The user requirements for improved design aids are presented, with implementation guidelines and hardware/software alternatives.

A SYSTEMS APPROACH TO HULL STRUCTURE DESIGN

引用

naval ENGINEERS JOURNAL 1970年第5期82卷 59-&页

作者： RAWAT, P who began his education in his native India received a Bachelor of Technology degree with honors from the Indian Institute of Technology in 1957. His subsequent education includes S. M.‘s in Industrial Management and Naval Architecture & Marine Engineering from M. I. T. in 1961 and a professional degree in Naval Architecture from the same institution in 1965. Rawat's career began as a Naval Architect in preliminary design with the Hamburg firm of Howladtswerke in 1958. A year later he performed as a research assistant in M. I. T.'s School of Industrial Management for a Ford Foundation Project for a top management training program for India. After this two-year period he acted as the head of the Department Head of Engineering at the Ghana Nautical College in West Africa until 1963. He returned to M. I. T. afterwards to work as a research assistant in Naval Architecture on structural optimization programs. From 1965 to 1966 he filled the capacity of Naval Architecture with M. Rosenblatt & Son in the area of structural design on such projects as MOHOLE AGOR 14 and Catamaran Hull. Since 1966 Rawat has been working in various capacities with Litton Industries: Senior Naval Architect on the FDL Project Section Manager of Hull Structures for the LHA and DD Projects and his present position as Section Manager for Computer Aided Ship Design.

Many useful conclusions can be drawn if hull structural design is considered as a system. Proper definition of system objectives enables setting up of meaningful long range and intermediate goals. Current state-of-art in systems engineering is such that the system objectives can be denned in mathematical form. This provides meaningful scales for progress measurement. The engineering function is to meet the goals set by systems engineering. The state-of-art in engineering has a considerable impact on the definition of system objectives. In recent times we have made considerable progress in developing analytical techniques. Many interesting conclusions result from our experience in using the analytical tools in an iterative manner for design. By using relatively simple algorithms for iteration the analytical processes can be sequenced in such a manner that optimum solution is guaranteed even under a large and complex set of design constraints. Use of computers makes it possible to generate the scantlings using iterative approach with such speed that many important structural configuration decisions can be made by means of thorough parametric analyses. The system objectives therefore are very different in scope today and they should be further modified as technology advances. There are several problems that can be recognized and solved in the systems context. Smooth man-machine operation is an example of this.
