As the monthly progress reports were received from the various proj- ects, the shipping requirements were projected and submitted to the Task Force. Projects were kept advised when ships would be on berth at Oakland, enabling the project people to move their equipment to the port in time to meet sailing dates with a minimum waiting period. The J-4 liaison officer at Oakland kept the J-4 office informed regarding the receipt and movement of cargo at the port. Equipment began arriving at the Naval Supply Center, Oakland, in November 1957. Approximately 18,300 measurement tons of cargo were moved to the Eniwetok Proving Ground by MSTS vessels. All cargo vessels were discharged and loaded at the deep water plier at Parry Island. Cargo was lifted on reefers, regular cargo vessels, and in one instance a commercial cargo ship. Three trips were made by the Brostrom, a C-4 type cargo ship which is ideally suited for the type of cargo that Task Group 7.1 ships, which consists primarily of large scientific trailer vans. The Brostrom arrived at the EPG as follows: January 23, February 25, and April 2, 1958. Over 170 heavy lifts were made to the Proving Ground, of which there were 117 vana of over 2000 cu ft each. In addition there were approximately 46 amaller trailers and truck vans that did not meet the 2000-cu ft criterion of a large van. The peak of water shipments was during the months of February and March 1958.
