      <title>SPRINGSWEEP-AN ADVANCE IN SURFACE OIL CATCHING TECHNIQUES</title>
      <link>https://trid.trb.org/View/166549</link>
      <description><![CDATA[The Springsweep system uses the Swedish patented Troilboom to give a high and continuous oil encounter rate to a powerful suction unit, all readily mountable on a single ship, this avoiding the station keeping problems of multiple vessel arrangements.  The Troilboom system actually funnels the oil towards the suction head (capacity 40 cum per hour) by being towed not from points on the boom itself, but from a bridle wire running inside the curve of the boom and from which the skirt-like boom is loosely rigged.  Springsweep's place in UK pollution abatement policy is discussed.]]></description>

      <title>TESTING OIL BOOM BEHAVIOR</title>
      <link>https://trid.trb.org/View/154233</link>
      <description><![CDATA[The Norwegian Hydrodynamic Laboratories (NHL) has studied the behaviour of oil booms towed at sea.  This has partly been done with scale models, partly theoretically and also by partaking in full scale experiments.  As experiments are costly, the work has concentrated on making a theoretical model for the behaviour of booms towed at sea.  The computer program developed in Trondheim is constructed on a basic description of an oil boom.  The forces induced by sea and oil are founded on a two dimensional strip theory.  The program calculates the movements of the boom and the relative movement between boom and water.  In the program the boom is divided into elements.  A wave pattern is directed into the U-shape of the boom, and for each time-period, e.g. 0,1 sec., all the forces working on each element is calculated.  A set of equations are put into use, and this routine is repeated for as many time-periods as necessary.  All the parameters of the boom can be changed individually and the influence of each change on the other elements can be studied.  The behaviour of a real boom can in this way be assessed using the measurements and figures from it, and the behaviour can be accurately predicted.  For additional information contact NSFI.]]></description>

      <title>SAINT LAWRENCE RIVER ICE BOOM MODIFICATION STUDY</title>
      <link>https://trid.trb.org/View/144100</link>
      <description><![CDATA[The objective of this study was to prepare designs and specifications for improvements to existing ice booms in the international portion of the Saint Lawrence River to allow extended season navigation through 31 December of each year. The study involved the construction and operation of a distorted scale (horizontal scale 1:150, vertical scale 1:60) hydraulic model of the section of the river extending from Stillwells Point, New York downstream to Red Mills, New York. The design and construction of the model are described. The model was used to develop and test concepts for improving the booms to permit navigation while maintaining or improving the stability of the ice cover and the hydraulic integrity of the river. These tests involved model ship passages through consolidated and unconsolidated ice conditions with and without simulated high winds. Results from the model were used to design structural components and to assess the impact on levels and flows of the river and Lake Ontario due to ice passing downstream of the booms.]]></description>

      <title>OIL RECOVERY SYSTEM FOR OPEN SEA USE. THE SPRING-SWEEP SYSTEM</title>
      <link>https://trid.trb.org/View/91586</link>
      <description><![CDATA[The problems of oil recovery at sea are discussed in terms of oil encounter rate and the effects of waves on skimmer and boom performance.  A description of the Warren Spring Laboratory experimental arrangements for boom and skimmer evaluation at sea is given.  Boom requirements and boom design are dealt with.  The system employs a skimming head of low inertial mass to skim the oil collected by the boom. The use of the total system at various stages of the development, at the "Ekofish", "Amoco Cadiz" and "Eleni V" incidents is described.  Order from NSFI as No. 17259.]]></description>

      <title>DYNAMIC RESPONSE OF NORTH SEA CRANES</title>
      <link>https://trid.trb.org/View/50388</link>
      <description><![CDATA[Dynamic tests were carried out on two different types of pedestal crane in use in the North Sea.  Boom stresses, hook loads and pedestral moments are tabulated for lifting a 5 ton test weight from a supply boat in rough weather.  The significance of the recorded values is discussed and compared with results from a standardized 5 ton drop test at different operating radii.]]></description>

      <title>DEVELOPMENTS AND DESIGNS TO IMPROVE OFFSHORE CRANES</title>
      <link>https://trid.trb.org/View/51818</link>
      <description><![CDATA[The Harnischfeger Corporation of Milwaukee, Wisconsin, has evolved an entirely new design of pedestal mounted crane, designed specifically for use on offshore drill rigs.  The new crane has a maximum capacity of 50 tonnes and an 18.28 m long heavy duty boom complete with a 1.5 m whip extension specially designed for operation in heavy wind conditions. Boom extensions are available with pin connections for easy assembly or disassembly, giving lengths up to 36.5 m.  For ease of handling and assembly, the crane has been designed in modular component form requiring only 16 pins and four bolts to complete assembly.  There are six main components; the base, A-frame, power unit, gantry, cab and boom, and the heaviest component weighs only 16,000 lb.  They are designed to be easily air lifted and assembled on rig or platform with minimum time and labor.]]></description>

      <title>EXPERIMENTAL PROCEDURES USED IN THE DEVELOPMENT OF OIL RETENTION BOOM DESIGNS</title>
      <link>https://trid.trb.org/View/1622</link>
      <description><![CDATA[The experimental procedures used in the development of oil retention boom design criteria are presented in detail. Emphasis is placed on the procedures used to determine the oil containment ability and structural loads on the boom as a function of environmental conditions. The critical scaling parameters for oil containment tests are presented and the test procedures which have been developed are described. It is concluded that it is critical to scale both Froude and Weber number. Tests to determine structural loads can be conducted using standard ship towing tank procedures. However, it is necessary to scale the elastic properties of the boom and its mooring system. There are uncertainties with respect to some parameters which cannot be properly scaled in oil containment tests. Thus, carefully conducted full scale trial results are required.  Available procedures and current plans to obtain full scale data are presented.]]></description>

      <title>LIGHTWEIGHT OIL CONTAINMENT SYSTEM, LOW TENSION BARRIER SYSTEM. PART I</title>
      <link>https://trid.trb.org/View/1703</link>
      <description><![CDATA[The report presents the results of studies and tests of a low tension light weight oil containment system.  The system is capable of deployment from an aircraft and deploys rapidly with a minimum of support equipment.  The barrier design described uses an external tension shock absorbing bridle line to insure the barrier a high degree of high sea surface confirmability.  (Author)]]></description>

      <description><![CDATA[The report presents the results of studies and tests of a heavy duty oil containment system.  The system is capable of air transportation to the vicinity of its intended use. Deployment is accomplished using larger Coast Guard vessels or navy salvage ships.  The design is intended for long deployment periods.  The barrier concept described herds the oil into a containment area designed using multi booms to minimize entrainment losses.  The barrier design uses flooded sections of dynamic and static stability and nonflooded sections for buoyancy.  (Author)]]></description>

      <title>FLUID DYNAMICS OF FLOATING OIL CONTAINMENT BY MECHANICAL BARRIERS IN THE PRESENCE OF WATER CURRENTS</title>
      <link>https://trid.trb.org/View/2696</link>
      <description><![CDATA[Experiments on oil containment by mechanical barriers have led to identification of the important physical phenomena controlling the extent of an oil slick and have illustrated flow conditions leading to failure of the barrier.  A mathematical model has been developed to generalize the experimental results.  Example calculations and design charts are presented which may be useful in deciding whether stationary mechanical barriers would work at all in given cases, and in selecting the proper depth of skirt and length of boom required in those cases where mechanical barriers are feasible.]]></description>

      <title>STUDIES OF OIL RETENTION BOOM HYDRODYNAMICS</title>
      <link>https://trid.trb.org/View/1705</link>
      <description><![CDATA[Results of an experimental investigation of oil containment hydrodynamics are presented with theoretical analyses to help explain the experimental findings.  Two-dimensional model tests were performed using several petroleum products including diesel fuel and motor oil.  Test variables in addition to oil properties were current, interfacial tension, gravity waves, slick volume, containment boom geometry, and boom depth.  Also studied were three-dimensional effects and the efficiency of using absorbent additives and multiple boom configurations as containment aids.  (Author)]]></description>
