      <title>ACCELERATIONS ON CARGO</title>
      <link>https://trid.trb.org/View/395135</link>
      <description><![CDATA[A project at MARIN (Maritime Research Institute Netherlands) to measure the accelerations at sea of three heavy lift vessels is described. The purpose was to enable comparison between these actual accelerations and those obtained from prescribed design calculations and long-term prediction methods and PSO so to test the validity of the feeling, on the part of some companies transporting heavy lifts, that the criteria of classification societies are not straightforward and sometimes require design values that are unnecessarily high.]]></description>

      <description><![CDATA[Bubble cavitation has often been associated with a high noise level. Experimental studies in the depressurized towing tank of MARIN (Maritime Research Institute Netherlands) indicate, however, that this applies to model-scale situations rather than to full-scale conditions.]]></description>

      <title>MARIN HIGH SPEED DISPLACEMENT HULL FORM DESIGNS</title>
      <link>https://trid.trb.org/View/397181</link>
      <description><![CDATA[This article gives an up-to-date overview of a 10-year project started in 1979 at MARIN, Maritime Research Institute Netherlands, to improve the performance of high-speed displacement vessels, especially with regard to their seakeeping qualities. It describes the organization of the project, the set-up and geometry of the model series, experiments in calm water and in waves, and a computer system designed to make the wealth of information gathered more accessible to designers. The computer system is not a full CAD system; it involves only hull geometry and two hydrodynamic parts of the complete design problem. It is planned to include two general computer programs to widen the field of application.]]></description>

      <title>THE WAKE ADAPTED DUCT--A NEW DEVELOPMENT</title>
      <link>https://trid.trb.org/View/397182</link>
      <description><![CDATA[A new wake-adapted duct developed at MARIN, Maritime Research Institute Netherlands, is described and illustrated. The duct is claimed to compare favorably with other energy-saving devices. Its design takes as a premise that the duct must be placed at the hull location where propeller suction influence is maximal, and this location is determined by flow calculations or experiments. This design method makes the chances of success very high, in contrast to those for devices that are designed on the basis of trial and error.]]></description>

      <title>HIGH-SPEED DISPLACEMENT SHIPS UNDER EXTREME CONDITIONS</title>
      <link>https://trid.trb.org/View/397183</link>
      <description><![CDATA[In the design stage, it is important to be able to reliably and accurately predict the seaworthiness of a ship under extreme conditions so as to be able to evaluate ship survivability. At MARIN, Maritime Research Institute Netherlands, a time-domain computer program that simulates the behavior of high-speed displacement ships under extreme conditions has been developed as a way of arriving at that assessment.  Previously, survivability could only be judged--and at that, only to a limited degree--by model tests.]]></description>

      <title>PERFORMANCE PREDICTION FOR WATERJET-DRIVEN CRAFT</title>
      <link>https://trid.trb.org/View/397585</link>
      <description><![CDATA[The properties that make waterjet propulsion advantageous for special-design vessels are enumerated. Propulsive efficiency at lower speeds, however, is rather low. The JETEFF computer program has been developed at MARIN (Maritime Research Institute Netherlands) to help determine the propulsive efficiency of waterjet-driven vessels. The computational model is briefly described and appropriate applications are indicated. Typically, the program might be used to compare the propulsive efficiency of a waterjet system with that of a propeller system.]]></description>

      <title>SEAKEEPING CONSIDERATIONS</title>
      <link>https://trid.trb.org/View/397586</link>
      <description><![CDATA[For motor yachts and powerboats, seakindliness is a factor that can be strongly influenced at the design stage through the judicious selection of the main particulars and the hull shape. The discussion of this point ranges over hull shape for displacement yachts; hull shape for planing yachts; forebody shape; acceleration levels and ride quality; vertical-motion levels; horizontal-motion levels; global and local forces; and form details and appendages.]]></description>

      <title>THE INDISPENSABLE LABORATORY</title>
      <link>https://trid.trb.org/View/397587</link>
      <description><![CDATA[New developments in motor yachts and other vessels and maritime structures would not have advanced so rapidly were it not for the availability of physical model testing. The phases of model test programs at MARIN (Maritime Research Institute Netherlands) are described as being typical of such laboratory programs and are: (1) preparation, (2) calm-water testing, (3) prediction of full-scale behavior in calm water, (4) tests of behavior in a seaway, and (5) tests to determine what maneuvering performance should be expected.]]></description>
