      <title>A COMMERCIAL SAILING SHIP FOR THE SOUTH WEST PACIFIC OCEAN</title>
      <link>https://trid.trb.org/View/87783</link>
      <description><![CDATA[The sailing ship-intended for carrying packs of sawn timber-has a deadweight capacity fo 2200 tons, and a predicted year-round average speed of 12,5 knots.  Besides a technical description of the vessel, financial and operational feasibilities are considered.  Order from NSFI as No. 16286.]]></description>

      <title>SAILS FOR THE AUXILIARY PROPULSION OF A VLCC TRADING ON THE NORTHERN EUROPE--PERSIAN GULF ROUTE</title>
      <link>https://trid.trb.org/View/87784</link>
      <description><![CDATA[The paper considers the possibility of equipping a VLCC operating between Europe and the Persian Gulf with auxiliary sails in order to save fuel when winds are favourable.  In unfavourable winds, the vessel proceeds under power.  The estimated net earnings of the sail-equipped ship are compared with those for the same vessel without sails. Order from NSFI as No. 16287.]]></description>

      <title>A BROAD APPRAISAL OF THE ECONOMIC AND TECHNICAL REQUISITES FOR A WIND DRIVEN MERCHANT VESSEL</title>
      <link>https://trid.trb.org/View/87785</link>
      <description><![CDATA[The paper is in two parts.  Part A is concerned with the current economic prospects of sail as a direct competitor to the oil fueled motor-ship.  The operating and constructional costs of a typical cargo vessel of about 20,000 tonnes displacement as a motor vessel and as a sailing vessel are discussed.  Part B is concerned with the technical characteristics of ships of this size fitted with several alternative means of wind propulsion including the "PROLSS" dynaship, various forms of rigid wing sail, windmill propelled vessel with a water propeller, and a "flettner" rotorship.  Order from NSFI as No. 16288.]]></description>

      <title>STATISTICAL QUALITY CONTROL AND PAVEMENT THICKNESS DESIGN</title>
      <link>https://trid.trb.org/View/87792</link>
      <description><![CDATA[The quality of a road is described in terms of its physical attributes, e.g.  the thickness of its pavement, the CBR of its subgrade, the distribution of the particle sizes in its base course etc.  The values of all such attributes vary between limits of small or large range.  For the purposes of establishing the quality of an existing road at appropriate levels of confidence, the number of samples are determined by the use of the equations presented.]]></description>

      <title>COMPARISON OF SOME FEATURES OF HIGH SPEED MARINE CRAFT</title>
      <link>https://trid.trb.org/View/1509</link>
      <description><![CDATA[Some of the principal features of the main types of high speed marine craft are examined as an aid to assessing their present effectiveness.  The craft considered are those which have service speeds greater than 30 knots and which are large enough to serve a practical commercial or naval purpose.  The three main types are high speed displacement or planing craft, hydrofoil ships, and hovercraft.  Power requirements are considered for these craft in calm water, and in waves representing conditions likely to be met in typical service operations.  This performance comparison is extended to include some trial and service data.  Published and other available information on the disposable load factors for various types of craft are then summarized, and it is suggested that apparent variations in structural efficiency are largely due to technical choices based on commercial considerations and to differences in certification requirements.  Simple methods are used to compare some design features selected on economic considerations rather than technical efficiency.  Cost criteria are examined and used in a broad discussion from which tentative conclusions are drawn about the present relative overall operating costs for foilcraft and hovercraft.  Some characteristics of various types of craft which can affect their use in particular practical operating conditions are considered.]]></description>

      <title>HULL AND BULBOUS BOW INTERACTION</title>
      <link>https://trid.trb.org/View/2845</link>
      <description><![CDATA[Resistance, sinkage, trim and wave pattern resistance were measured at two drafts in tests of a 0.80 block coefficient Series 60 model at the Glasgow University Experiment Tank. All the tests were repeated with each of two different protruding bulbs fitted to the model.  Records were also made of the wave profiles produced by the naked hull, the hull and bulb combination and the bulb alone.  Calculations were made to estimate the vertical force acting on each bulb.  The results confirm previous findings that the addition of a bulb affects viscous as well as wave resistance.  The usual assumption that hull and bulb wave profiles may be linearly superimposed to give the wave profile of the hull-bulb combination is found to be invalid for the model tested.]]></description>

      <title>ANTIFOULING PAINT FILM STRUCTURE, WITH PARTICULAR REFERENCE TO CROSS-SECTIONS</title>
      <link>https://trid.trb.org/View/2844</link>
      <description><![CDATA[Experimental program is presented in which samples of antifouling coatings, made of a cuprous oxide pigment in an unplasticized vinylresin matrix, were studied by using scanning electron microscopy.  Cross-sections prepared by fracturing frozen antifouling coating specimens were easily prepared, showed little distortion and yielded detailed information about the internal structure of antifouling coatings when examined by scanning electron microscopy. Cross-sections prepared by ultra-microtomy yielded more limited information because this technique produced distortion of the revealed cross-section.  There is a linear correlation between leached matrix thickness and the volume fraction of pigment in these coatings.  Unleached coatings containing low volume fractions of cuprous oxide were nonporous throughout their thicknesses.]]></description>

      <title>AUTOMATION AND REMOTE CONTROLS AT SEA; A SHIPOWNERS VIEW</title>
      <link>https://trid.trb.org/View/1515</link>
      <description><![CDATA[Automation and remote controls at sea. A shipowners view; n 5 May 1970 p 141-6; The shipowners objectives in introducing sophisticated control equipment and the factors he should weigh before making such a decision are examined. Other factors discussed are-choice of system; division of responsibility between owner, shipbuilder and supplier; installation requirements on shipboard; commissioning techniques at the fitting-out berth and on sea trials; maintenance by the supplier after delivery; repair facilities; training of ships officers; and effects of improved instrumentation on surveys.]]></description>

      <title>MAMMOTH SHIPS</title>
      <link>https://trid.trb.org/View/1516</link>
      <description><![CDATA[The economic advantages of increased size are illustrated. The various technical problems which arise from greater ship size are reviewed, including-freeboard, subdivision and tonnage; stability; ship motions; ship resistance; propulsion; rudders and steering; vibration; thermal stresses; and strength. It is concluded that it is technically possible to construct vessels larger than the largest built to date. Choice of dimensions depends upon economic feasibility and cost optimization. Further research in various branches of naval architecture is needed since practice has outstripped the advances in knowledge from theoretical and experimental investigations which are necessary if mammoth ships are to operate efficiently.]]></description>
