      <title>LOCOMOTIVE CONTROL COMPARTMENT SAFETY PROGRAM: LOCOMOTIVE HEAVY AXLE LOAD TESTS</title>
      <link>https://trid.trb.org/View/466146</link>
      <description><![CDATA[The Federal Railroad Administration sponsored a program to evaluate the wheel on rail dynamic safety performance of locomotives with increased cab weight at the Transportation Test Center, Pueblo, Colorado.  The increased weight represents the weight of a cab reinforced to protect the occupants in the case of an accident.  The program consisted of on-track tests to evaluate the safety performance, and assembly and validation of a mathematical model of the locomotive to be used to extend the scope of the track tests.  Tests were performed to measure the suspension characteristics of a locomotive.  The data was used as input to a mathematical model that could be used to simulate the locomotive under a wide range of track conditions.  The model was verified by comparison with the results of the on-track tests.]]></description>

      <title>APPLYING ENGINEERING STATISTICS IN WEIGHT ENGINEERING</title>
      <link>https://trid.trb.org/View/435323</link>
      <description><![CDATA[The prediction of weights of offshore platforms is a very important task. It can in fact be a matter of life and death for a project. The investments are often based on a  /tonne figure and plans are based on manhours/tonne. If you put too many tonnes into an estimate to make sure you are on the safe side, the costs may very well be too much for management to swallow. On the other hand, if you are too optimistic, you may have been the source of wasting time and money on a dead duck. The proposal presented in this paper is to take the average of ten, safe, ordinary platforms as a weight estimate. See also previous and following abstracts.]]></description>

      <title>COST-SAVING IMPLICATION OF WEIGHT CONTROL FOR ABANDONMENT AND REMOVAL</title>
      <link>https://trid.trb.org/View/435326</link>
      <description><![CDATA[The purpose of this paper is to consider the role of weight control in relation to abandonment and removal of platforms. Clearly, the subject of weight control has immediate implications with regard to cost of platform removal since it is evident that a sizeable proportion of the overall costs would be associated with lifting modules and jacket, and loading these onto transportation barges for ultimate disposal. The strategy for removal of a platform is evidently unlikely to be the exact inverse of the stages involved in the platform's installation. What would be an optimum course of action for the installation of a platform need not, and in general would not, apply in the reverse. The objective overall in abandonment would be to investigate all possible methods and to determine the one that was economically the most attractive.]]></description>

      <title>CONTINUOUS WEIGHT MONITORING FOR OFFSHORE STRUCTURES</title>
      <link>https://trid.trb.org/View/435333</link>
      <description><![CDATA[Given that accurate knowledge of weight and its distribution are considered vital during all phases of the life of an offshore structure, it would seem logical to provide a permanent means of measuring the actual weight applied to the supports of a structure. this would allow the Weight Engineering Manager to know the weight "on demand" and to keep an accurate record of absolute weight and of weight changes from the start of deck fabrication right through to abandonment as well as providing important structural safety checks. Much has changed in the technology of both force measurements and instrumentation in recent years and it is the object of this paper to inform weight engineers what can be done with the latest techniques.]]></description>

      <title>WEIGHT DEFINITION AND CONTROL FOR FAST CRAFT</title>
      <link>https://trid.trb.org/View/439927</link>
      <description><![CDATA[A standard for weight definition and an approach to weight control is presented for modern motor yachts and other craft. This includes a definition of weight and loading conditions for these vessels which can be related to attainable vessel speeds. The weight control plan addresses concept through detail design, construction, delivery and service life.  The procedure is adaptable to all types of hull structural material.  Weight curves developed from regression of previous vessel data are included and cover a variety of pleasure and commercial craft. Examples of the effect of weight control on speed are given. Recommendations for application of the procedures are offered.]]></description>

      <title>COMPUTER AIDED OPTIMUM STRUCTURAL DESIGN OF ACTUAL OIL TANKERS (VLCC)</title>
      <link>https://trid.trb.org/View/434049</link>
      <description><![CDATA[Attempts have been made to perform the minimum structural weight design of oil tankers, however, the problem of excessive computer usage has not been solved. To overcome these difficulties an analytical rather than a numerical approach is suggested. Existing slope deflection methods present difficulties. Therefore the authors have developed a generalised slope deflection method taking into account axial deformation and rigidities. The authors compare this with other structural analysis methods to show its effectiveness. Supporting methods have also been devised. A minimum hull weight program is developed based on the generalised slope deflection method and Hooke and Jeeves direct search method. By this program a minimum weight design of actual oil tankers of 280,000 DWT is carried out.]]></description>

      <title>ANALYSIS OF THE WEIGHT OF THE HULL COMPONENTS OF BULK CARRIERS</title>
      <link>https://trid.trb.org/View/436404</link>
      <description><![CDATA[The article analyses the weights making up the hulls of bulk carriers, with given midship section geometry designed according to Registro Italiano Navale rules. The hull weight of 112 ships is examined, showing the trends in some non-dimensional parameters characterising the hull. A detailed analysis is made of the position of the neutral axis, both as derived from the prescribed preliminary calculations and also derived from the corrections made to achieve the bending modulus specified by the Registro Italiano Navale.]]></description>

      <title>COMPUTER AIDED MINIMUM WEIGHT DESIGN USING BEM</title>
      <link>https://trid.trb.org/View/438390</link>
      <description><![CDATA[A mathematical programming technique and the boundary element method are combined to create the optimised shape of machine elements and structural components subjected to static external loads. The structural stress/deformation analysis and sensitivity analysis can be performed more correctly and elegantly by boundary discretisation alone. The optimiser employed here is the so-called 'method of inscribed hypersphere' which is known to be fitted for the object and constraint functions with weak nonlinearity. Minimum weight design of two-dimensional elastic structures is considered under the prescribed constraint conditions. Some numerical results demonstrate the validity of the proposed computational system even for the problem with the restriction expressed by an inequality.]]></description>

      <title>LIFETIME WEIGHT ENGINEERING - A PROGRESSIVE APPROACH</title>
      <link>https://trid.trb.org/View/435324</link>
      <description><![CDATA[This paper describes a comprehensive weight engineering methodology for offshore platforms developed by Earl and Wright in conjunction with Humphreys and Glasgow. A single unified philosophy for the whole installation is presented which covers the lifetime of the facility encompassing the concept design phase through to the operational phase of the platform. The need for continuity of weight data management is emphasised together with the advantages of establishing at an early stage a single policy which covers the weight engineering for the complete platform. Methods and systems required for a platform's operating phase are described and how these relate to the weight engineering carried out during earlier phases. The benefits of continuing control for cost savings, safety assurance and assessment of the effect on structural integrity of topside modifications are addressed in the context of current design trends. See also previous and following abstracts.]]></description>

      <title>METHOD FOR ESTIMATING THE STEEL AND THE LIGHT SHIP WEIGHT IN SHIP DESIGN</title>
      <link>https://trid.trb.org/View/449731</link>
      <description><![CDATA[Weight calculation is of significant importance in ship design. The steel and the light ship weight do not only influence the design itself, but are often used to estimate the costs for design and production and are therefore critical for tendering a newbuilding project.  A method for estimating the steel and the light ship weight of different types of merchant ships has been developed and implemented in a PC version under the operating system MS-DOS. The method is described.  Experiences gained with this program in the project department of a German shipyard which builds ships up to 25,000 tons deadweight are discussed.]]></description>
