CHAPTER IV, SECTION 4 There were encompassed in OPERATION CASTLE a wide variety of marine requirements included among which were: (a) Water transportation and cargo. for personnel (b) Locating, improving and marking boat channels. ‘c) Overhaul of existing and planting of additional mooring buoys. id) Movement, mooring and_ positioning ot barges fitted as Zero Stations. te) Support of Scientific groups in assembly and planting of waterborne Scientific Stations. (f) Assistance to seagoing vessels in berthing. (g) Assistance in installation and the matntenance of ali underwater piping. (h) Deep sea diving. (i) Operation of cable laving boats. ' WATER TRANSPORTATION. During the construction phase, intra-atoll water transportation requirements were met by the Holmes & Narver boat pool. For the operational phase the marine craft at the Jobsite were augmented by 19 LCMs and 5 LCUs provided by Comfot omen reas . ere mander Task Group 7.3. The volume of traffic and the gencral over-all cargo carried was closely watched and regular boat schedules were published so that the maximum use of available operating craft was made. The responsibility for the assignment of craft to meet the varying dailv needs was delegated to the Marine Dispatcher. During the operational phase at Bikini Atoll, the scheduling was assumed by a pane! consisting of the H&N Assistant Marine Superintendent and the U.S. Navy Boat Pool Officer. All operating cratt and dispatchers’ offices were equipped with ship to shore radios. This assured personnel safety and rescue. facilitated the control of the craft when out of sight of the dispatcher, and permitted diversion of craft in the lagoons as the need for this arose. All craft operators were recuired to report their departure from a site and their estimated time of arrival at their destination with information as to their needs for assistance in loading or unloading their cargos by riggers. heavy equipment operators or others. The dispatchers, therefore, could make the necessary arrangements for this assistance in advance and thereby reduce the time tnat the craft had to remain on the beach or at the dock. DUKWs were wiaely used in connection with work on reef stations: on sites inaccessible by boats: for manv scientific recovery jobs as they are somewhat self-decontaminating; and SESSSTLAT EELATSARETE . 2 ee Beye : 7 a Figure 4-25. _ ok DUKW on Site Bravo.
