      <title>DETERMINATION OF DECOMPOSITION PRODUCTS FORMED DURING WELDING ON PAINTED STEEL</title>
      <link>https://trid.trb.org/View/52244</link>
      <description><![CDATA[The work involved in the project was carried out at Farg AB International and ESAB between July 1973 and November 1974. The object was to find a suitable method of determining the air impurities formed when welding shop-primer-coated steels.  The tests were carried out with five different manual welding electrodes with deposition rates ranging from 125% to 240%, using different combinations of electrodes and primers.  Unalloyed steel plates type SIS 14 13 12, 250 x 50 x 12 mm were used, sandblasted to a degree of accuracy of Sa 2 1/2.  Shop primer was applied to both sides of the plates, with a dry-film thickness of 25-30 millimicron for four of the primers used.  For iron-oxide pigmented shop primers based on epoxy resin a dry-film thickness of 30-35 millimicron was applied.  A high-pressure spray gun was used for applying the primer and drying time, prior to welding, lasted for over a month.  The welding and sampling equipment is described and the results presented in a series of tables.  It was shown that the presence of a coating of dry-film thickness of approximately 30 mm considerably increases the amount of solid particles when welding in ship primers with a high zinc content.  When using other types of primers, this increase is insignificant, and the fume-extraction equipment used should be sufficiently effective.  The zinc tetraoxy-chromate present in most shop primers as a rust inhibitor need not be taken into consideration.]]></description>

      <title>ENVIRONMENTAL PROTECTION IN A SHIPYARD</title>
      <link>https://trid.trb.org/View/147059</link>
      <description><![CDATA[The Author, of the Stralsund shipyard in East Germany, gives a brief account of tests carried out on four types of oil-boom.  The tests were made to determine the suitability of the booms for preventing oil spillage escaping from the shipyard into the waters outside, and to ascertain their capability of withstanding the water and other local conditions for lengthy periods.  The tests provided valuable information on the design of oil-booms for this purpose and for other applications.  Order from BSRA as No. 51,724.]]></description>

      <title>100,000 DWT FLOATING DOCK "SAGAMI"</title>
      <link>https://trid.trb.org/View/46249</link>
      <description><![CDATA["Sagami", a floating dock newly built for IHI's own use in view of the shortage of repair docks in Japan, is now in operation at the site of IHI's Yokohama Shipyard.  Being the "solid type" floating dock first constructed in Japan, she is moored at the site by the sliding guide type mooring equipment which was developed by IHI for use with "Sagami" for the purpose of ensuring safety and reliability in mooring under difficult conditions, especially in typhoon weather.  Beside the above, she has many other unique points: two main lines of ballast water piping with two large dewatering pumps are installed on the basis of our extensive experience in the designing of super tankers, which enables her to operate quite easily and speedily; moreover, a complete drainage water cleaning system is adopted.  Namely, in addition to the ordinary sewage system for drainage from showers and W.C.s, IHI-CHEMAP funda filter is provided to treat dock bilge water including 5,000 tons of water discharged from a drydocked ship.  She is further modernized with powered equipment such as air-operated bilge blocks, painting stages of both sides, ship position fixing system, hydro-jet cleaning system and so on.]]></description>

      <title>SHIPYARD PROBLEMS WITH OILY WASTES</title>

      <title>ENVIRONMENTAL CONTROL IN SHIPBUILDING AND SHIP REPAIR FACILITIES</title>
      <link>https://trid.trb.org/View/11029</link>
      <description><![CDATA[This paper deals with environmental control in both shipbuilding and ship repair facilities.  The distinction is intentional.  The first steps in dealing with and preventing pollution problems is the recognition of their sources and the evaluation of their magnitude.  The recognition and evaluation process quickly separates shipbuilding facilities from ship repair facilities.  On the other hand, combining shipbuilding and ship repair into the same facilities the environmental control problems are additive.  The author reviews various state and federal pollution control legislation and its applicability to shipbuilding and repair facilities. Particular attention is given to the problem of handling solid wastes, oil and other liquid waste accumulations as well as pollutants occurring during the surface preparation and protective coating of ships hull.  It is also pointed out that there is no typical shipyard facility and no standard environmental control program which can be applied to all shipyards, each must be tailor made to fit the particular circumstances, and that program will be continually changing.  It also follows that if you cannot fit a given control program to a plant which cannot be defined as typical, you definitely cannot apply a simplified economic impact equation to the industry as a whole.]]></description>
