      <title>STRESS CONCENTRATION IN TUBULAR JOINTS</title>
      <link>https://trid.trb.org/View/60360</link>
      <description><![CDATA[Fatigue cracking caused by stress concentrations in tubular joints has been observed in some fixed platforms installed in hostile environments.  Consequently, the ability to assess the magnitude of the stress consentration is a prerequisite to dealing with the fatigue problem of tubular joints.  The problem of computing the stress concentration in three types of simple, nonreinforced joints: T-joints, K-joints and TK-joints is discussed.  Semi-empirical equations are presented for estimating the stress concentration due to axial loads and bending moments.]]></description>

      <title>APPLICATION OF PROBABILITY TO THE DESIGN OF SINGLE-POINT MOORINGS</title>
      <link>https://trid.trb.org/View/2663</link>
      <description><![CDATA[A procedure has been developed to analyze mooring forces and to aid the selection of design parameters for single-point mooring systems.  The results of an example study indicate that a conventional SPM buoy could be used successfully to permanently moor a 52,000-dwt tanker in water 260 ft deep under moderate sea conditions.  The procedure utilizes scaled-model data and environmental observations to derive force probability functions, which define the probability of exceeding any given force in the mooring system.]]></description>

      <title>STATISTICS OF OCEAN WAVE GROUPS</title>
      <link>https://trid.trb.org/View/13613</link>
      <description><![CDATA[Statistical parameters are derived to describe a group of consecutive waves that are large compared with the average wave height.  The parameters describing the statistics of ocean wave groups can be derived from the energy spectrum of the waves; they are then compared with those found for actual wave data.  Wave groups are an important consideration in designing mooring systems for large vessels subjected to long-period surge motions.]]></description>

      <title>DETUNING TANK--AN EFFECTIVE STABILIZING DEVICE</title>
      <link>https://trid.trb.org/View/13621</link>
      <description><![CDATA[The concept of the detuning tank is advanced.  The system is different from others in the sense that it does not try to compensate the action of the forces imparted by the sea to the floating body with properly phased compensating forces, but tries to prevent the sea from imparting the forces to the body.  The effectiveness of such tanks has been experimentally verified in model basin motion tests and studies.]]></description>

      <title>ANALYSIS OF THE TENSION LEG PLATFORM</title>
      <link>https://trid.trb.org/View/5150</link>
      <description><![CDATA[The tension leg platform is a type of moored stable platform whose buoyancy exceeds the weight.  The supplementary equilibrating downward force is supplied by tensioned vertical anchor cables; and heave, roll and pitch motions are suppressed.  A method is developed for predicting the forces in the mooring legs induced by wave action and platform motions in random and regular waves through the use of a linearized hydrodynamic synthesis technique.  Model experiments display good agreement with predictions.]]></description>

      <title>ANALYSIS OF PEAK MOORING FORCES CAUSED BY SLOW VESSEL DRIFT OSCILLATIONS IN RANDOM SEAS</title>
      <link>https://trid.trb.org/View/12370</link>
      <description><![CDATA[A procedure for calculation of peak mooring force caused by the long-period vessel drift oscillation is described.  The long-period drift oscillation is induced by the action of groups of high waves in random seas.  The procedure is developed from consideration of momentum flux change in ocean waves.]]></description>

      <title>SLOW DRIFT OSCILLATIONS OF A MOORED OBJECT IN RANDOM SEAS</title>
      <link>https://trid.trb.org/View/11940</link>
      <description><![CDATA[The phenomenon of the slowly varying drifting force on a moored object in a random sea is explained and illustrated from the results of several model tests with a rectangular barge.  Using the results of measured or calculated drifting forces on an object moored in regular waves, a prediction can be made of the drifting forces induced by wave trains consisting of regular wave groups.]]></description>

      <title>AIR BARRIERS AS OIL-SPILL CONTAINMENT DEVICES</title>
      <link>https://trid.trb.org/View/11924</link>
      <description><![CDATA[Based on experimental investigations it is concluded that air barriers will not completely retain oil in the presence of currents normal to the barrier as low as 0.75 ft/sec. The main body of the oil slick is retained, but oil drops are torn from the bottom of the slick by the turbulent surface current produced by the air barrier.  These drops are entrained in the current and swept through the bubble plume below the water surface.  Air barriers will retain essentially 100 percent of the oil when placed across the mouth of an enclosed body of still water if the oil density-water velocity combination produces a headwave type of flow.]]></description>

      <title>THEORY OF TRANSITIONAL AND TURBULENT FLOW OF NON-NEWTONIAN SLURRIES BETWEEN FLAT PARALLEL PLATES</title>
      <link>https://trid.trb.org/View/5151</link>
      <description><![CDATA[A theoretical model is developed which permits prediction of velocity profiles and frictional resistance factors for the isothermal flow of Bingham plastic non-Newtonian slurries in laminar, transitional, and turbulent flow between flat parallel walls, in rectangular ducts of large width to height ratios, or in concentric annuli with radius ratios approaching unity.  The theory is tested with available frictional resistance data for a range of Hedstrom numbers, and a set of theoretical design curves of friction factor vs Reynolds number is developed.]]></description>

      <title>EXPERIMENTAL AND THEORETICAL STUDY OF MOTION OF A MOORED BARGE</title>
      <link>https://trid.trb.org/View/5153</link>
      <description><![CDATA[Described is an experimental (both field and laboratory) and theoretical study of motion of a twin hulled moored barge as excited by ocean waves.  Comparison of results and conclusions are presented.  It is found that the linear theory of ships' motion using the slender-body approximation is an adequate tool for predicting the behavior of moored platforms in Sea States up to three.]]></description>
