CHAPTER III, SECTION 6 ed to Elmer was offloaded onto the pier. This condition was rectified and wing-to-wing discharge was initiated and permitted more rapid offloading of the vessels. Another problem was the loss of working hours due to the necessity of closing and reopening hatches because of frequent rain squalls and the need for overnight cover. This was overcome by the use of hatch tents fabricated at the Jobsite from scrap canvas. The use of these tents on the SS Swarth- more Victory eliminated the need for closing and opening the hatches 22 times during one operation, representing a saving in many hatch ours. At first, reefer cargo assigned to Elmer was offloaded at the deep water pier, and that for Fred was offloaded offshore and into LCMs for ferrying to the site. This proved cumbersome and time-consuming, particularly since cargo was sometimes stowed aboard the ocean-going vessel in a manner that required alternate discharge for each site. Therefore it became the practice to offload all refrigerated cargo at the Elmer deep water pier and to transship cargo assigned to Fred via trucks in LCUs. Page 3-32 During the peak of construction activity, difficulties developed because marine craft were urgently needed for other purposes. Experiments disclosed that refrigerated cargo could be moved by barge with noloss, provided it was well covered with tarpaulins; therefore this method of handling Fred refrigerated cargo was adopted. Because of the intense over-all shipping activity that developed during the peak construction period, the old cargo pier had to be used frequently. At one time there were a major cargo vessel and an LST at the deep water pier, an LST at the old cargo pier, and a reefer vessel in the lagoon being worked simultaneously. The wind and currents at times made ship handling and docking difficult, and the deep water pier sustained damage on several occasions and had to be taken out of operation until repairs could be effected; the old cargo pier was put into use during these repairs. The per-vessel tonnage of cargo that ar- rived at Jobsite is shown in Table No. 3-5 and 3-6.
