90 CHAPTER II, SECTION 3 ian * Figure 2-31. STATIONS: Barges at Outfitting Ship 10, 11, 12, 18, 14, and 15 PURPOSE: Barge Zero Stations SITES: Stations 11, 13, 14, 15 Moored Off Fox; Stations 10, 12 Moored off Gene USERS: LASL and UCRL CONSTRUCTION: Barge No. 10, 8-30-55/ 6-16-56; Barge No. 11, 122-55/6-2-56; Barge No.12, 9-7-55/7-2-56; Barge No. 13, 9-12-56/6-2-56; Barge No. 14, 11-22-55/6-13-56; Barge No. 15, 5-4-56/7-2- These Stations were U. S. Army type 231-A barges 120 long and 33’ wide, with a capacity of 585 tons. The stations were readied in the Barge Slip at Elmer. Station 12 was located at the Mike crater off Gene; the other five were moved via LSD to Bikini Atoll and moored off Fox. Station 10 was later relocated in the Mike crater and Station 15 was relocated between Charlie and Dog. A steel frame superstructure, with columns extending to the side plates of the barges, was erected for carrying large loads. A large, wooden room for scientific equipment was constructed with sufficient height to accommodate a 17’ sliding door on the starboard side. A removable 1-1/2 ton capacity monorail was provided with a clear hook height of 15’-10” over the working point of Station 15; hook height was 14’-10” for the other five stations. A 1-1/2 ton jib crane with a 14’ clearance was installed at the rail for loading and unloading. An 8’ x 10’ hatch in the roof of the large room was provided to facilitate loading scientific equipment during the outfitting period. Two smaller rooms for living quarters and mess, a small shack for a military sentry, and fresh water and fuel storage were provided. Whenall weights were aboard, ballast was installed to maintain an even keel. Installed in the device housing on Barges 13 and 14 were 1-3” x 1’-10"x 2’-3-14” collimating shields filled with concrete; each had a 1/2” diameter lifting ring welded to the bottom plate and extending up through the concrete. On Barge 15, a collimating wall constructed of 2x4’s and plywood, and containing three 24” diameter openings equally spaced, was built across the roof of the living quarters and tied into the wall of the device housing. Two Userfurnished vacuum pipes were installed, and the collimating wall on the starboard side was painted. The limitation in movement of the moored barge required that its working point be within Page 2-49
