      <title>METHODS OF REDUCING FITTING WORK DURING CONSTRUCTION OF A SHIP HULL IN THE BUILDING BERTH</title>
      <link>https://trid.trb.org/View/57836</link>
      <description><![CDATA[Today labor input in fitting operations constitutes 40% of the total labor input required for the construction of a ship hull in the building berth. Therefore, reduction of the volume of fitting operations is one of the most important objectives of improvement in hull construction. Reduction of the volume of fitting operations should be achieved by: -- perfecting the technology of their execution (for example, mechanization of correcting technological displacements and dimensional allowances, perfection of the methods of straightening of hull structures); -- reduction in deviations in the form and dimensions of hull structures in the building berth, which in turn should be based on improvement of the design factors (rational division into sections, well-thought-out design of field connections, and so forth), as well as technological factors (raising the accuracy of fabrication of hull sections, expanding the area of application of preliminary contouring of the sections in the building berth, and so forth).]]></description>

      <title>MARINE THROUGH-HULL FITTINGS AND SEA-VALVES</title>
      <link>https://trid.trb.org/View/16418</link>
      <description><![CDATA[These requirements cover marine through-hull fittings intended to be used above or below the water line and marine sea-valves for use as shutoff devices to effect positive closure of boat-hull penetrations.  These requirements do not cover the use of shutoff devices as a means of establishing or controlling the flow rate of a liquid. Requirements for the installation and use of marine through-hull fittings and sea-valves covered by this Standard are included in the Standards of the American Boat and Yacht Council, Inc.]]></description>
