      <title>PUMPS FOR OIL SPILL CLEANUP. TECHNOLOGY DEVELOPMENT REPORT</title>
      <link>https://trid.trb.org/View/76610</link>
      <description><![CDATA[A testing program was conducted by Arctic Canada Limited for the Environmetnal Protection Service whereby various commercially available pump designs were evaluated with respect to the requirements for general-purpose transfer pumping in oil spill cleanup situations.  In addition to making comments about the specific units tested, effort was devoted towards the development of criteria for pumps to be utilized for this application.  These criteria and the test observations led to generalizations about classes of pump designs in relation to oil spill operations.  Eleven pumps were tested representing a range of hydrodynamic and positive displacement designs.  Results indicate that a solids-tolerant positive displacement pump has application for spill cleanup use, whereas a diaphragm design shows much potential for an effective pumping system.]]></description>

      <title>POSITIVE DISPLACEMENT PUMPS FOR EMERGENCY TRANSFER OF HIGH-VISCOSITY CARGOES</title>
      <link>https://trid.trb.org/View/79169</link>
      <description><![CDATA[This article deals with the use of lightweight, easily handled pumping systems based upon the positive-displacement pump that can provide the solution to salvage problems which crop up when tankships loaded with oil or liquid petrochemicals run aground or sink.  The positive-displacement pump is more energy efficient at high viscosity.  Used in conjunction with present emergency transfer systems that are effective with low-viscosity liquids, this type of pump can reduce the environmental and financial impacts of tanker casualties.]]></description>

      <title>HYDRAULIC DRIVES FOR MARINE CARGO PUMPS</title>
      <link>https://trid.trb.org/View/24871</link>
      <description><![CDATA[Although this article deals with hydraulic drives for marine cargo pumps and discusses the relevant advantages of closed and open systems, the principles apply equally to winches and other installations. The author also deals with the economic and other factors that should be considered when choosing between open and closed hydraulic systems for use with centrifugal and positive displacement pumps.]]></description>

      <title>PUMPS FOR SALVAGE OF OIL CARGOES FROM STRANDED TANKERS</title>
      <link>https://trid.trb.org/View/308</link>
      <description><![CDATA[The Supervisor of Salvage requested a study of methods for pumping cargo oil from stranded tankers and an evaluation of a submersible 25-hp salvage pump modified to pump oil and other viscous liquids.  An investigation was made of the advantages and disadvantages of centrifugal and positive displacement pumps; strengths and head losses through oil transfer hoses of different sizes; power requirements, electric, hydraulic and pneumatic drives for salvage pumps; and heat required to lower cargo-oil viscosities for salvage.  A 25-hp centrifugal salvage pump with modified, interchangeable impellers was tested in oils of various viscosities to determine its capability for pumping various types of oil in cargo salvage operations.  It was found that for the required salvage operations the most practical salvage pump would be an electric, submersible, 18-hp pump capable of operating at 24 hp for limited periods, the modified submersible 25-hp salvage pump is satisfactory for salvaging oil cargoes if the steady-state temperature of the motor windings is limited to 140C, a 6-inch-diameter hose system should be used, and the standard 30/40-kw generator should not be expected to supply power to more than one 25- hp salvage pump when viscous oil is pumped.
