174A CHAPTER IV, SECTION 2 SECTION 2 MARINE OPERATIONS MARINE OPERATIONS quirements of REDWING,additional craft were A large marine facility was operated and maintained to provide intra-atoli water transportation and for other marine services such as locating, improving, and marking boat chan- nels; installing and maintaining small craft mooring buoys; assisting ocean-going vessels in docking; installing and maintaining underwater pipelines; operating cable-laying boats; deep and shallow water diving; and mooring of scientific barges. Upon completion of Operation CASTLE, three water taxis were returned to the United States and sold; four LCUs, one tug and two LCMswere returned to the U.S. Navy. During the interim period, 50 small craft of all types remained at Jobsite, of which approximately twelve were kept activated. To meet the re- TYPE acquired as follows: seven LCMs, nine LCUs, and one tug, all on a loan basis from the U.S. Navy; 41 DUKWson a loan basis from the U. S. Army; and three water taxis and one sea mule by purchase. In all exchangesof craft with the U.S. Navy, joint inspections were made by H&N (representing the AEC) and Navy personnel in accordance with existing agreements. The craft were activated on an as-needed basis for meeting requirements of Operation REDWING; during the peak of activity, all available craft were required. Essentially, the number of craft available were adequate, although there were a few isolated cases in which calls for water transportation could not be fulfilled immediately. The numberof craft available and their assignment to atolls during the peak period of activity are tabulated as follows: ENIWETOK BIKINI LCU 6 & LCM 18 DUKW 16 23 (one DUKW was.surveyed WATER TAXI 3 0 and one sunk.) BARGES 11 2 SEA MULE 1 ) (Six expended for TUG (YTL) 2 0 scientific use.) Totals 57 44 Grand Totals: 101 For the operational phase, the craft assigned to Bikini Atoll were augmented by those available from a Navy-operated boat pool. These Navy craft were assigned on an as-needed basis and were used to c: ry approximately 25 per cent of the peak loaa in Bikini Atoll. The H&N Superintendent of Marine Operations was delegated the duties of Transportation Control Agent for coordinating the use of boats in support of the scientific program. The working relationship established between the Navy and Contractor-operated boat pools was effective in providing satisfactory boat service. Transportation of cargo and personnel in both atolls was provided by boats on scheduled runs between camps or by the daily assignment of craft to specific missions. All requests for the use of cargo space in boats were submitted to a Marine Dispatcher on the day prior to departure. This procedure permitted an accurate breakdown of requirements for each day and provided for the maximum use of available operating craft. All craft and marine dispatchers’ offices were interconnected through voice radio, facilitating the control of craft and providing for the interchange of operating information. Page 4-23
