U.S.S. VIBURNUM KAN-57, ULITHI HARBOR Net Tender October i944 There WHS neither the time nor the material in the forward area for renewing the wOOd Cenetfuetien- Yet the ship could not proceed to a rear area until the hull was repeired- Therefefe, the Only solution was to lap a steel path over the damaged area. This Wee eeeempliehed by eempletely boxing in the ruptured keel with thirty-pound steel plate, which was secured with four-foot bolts. Twelve-inch H bars were bolted between the wooden frames on the upper side of the hold. Then the steel frames were welded between the b0Xed'in keel end the HHH bars. The pictures best illustrate the manner in which this was accomplished and the progress of the finished repairs. The steel plates were fitted to the frames and connected to the bow sheathing and steel sheathing aft. Q X 7 X if Mix? , 4 nj ' , Q -. e ll! it Wihwg tif, .

U.s.s. MAZAMA KAE-91 Fleet Ammunition Ship The U.S.S. MAZAMA while at anchor in Ulithi Harbor in a berth astern of the JASON was damaged by an underwater external explosion on the port side which blew in the side of number one ammunition hold. This hold was filled with ammunition. No explosion of ammunition resulted, but the hohiwasflooded. The explosion was presumed to have been caused by an enemy suicidal midget submarine or torpedo which was seen approaching from the starboard side of the ship. Parts of the Japanese body and shrapnel were found on the main deck of the MAZAMA. The explosion shook the bricks out of tw if the boilers. The shock also broke the foundation and the gear train housing of the diesel emergency fire pump located in number one hold. The temporary repairs were started by driving wooden wedges into the opened seams of the damaged hold. The water was then pumped out with submersible pumps. The ship's ballast was shifted to raise the bow as high as possible. A rigidly strengthened cofferdam was then constructed on the inner port side of number one lower hold over the tank top between frames 157 and l52i. This cofferdam extended from the deck to the overhead, and ranged in depth from two feet at frame l5Og to five feet at fram 137. The seams of the hull in the area outside the cofferdam were welded wherever possible. In some cases it was necessary to resort to caulking rivets and seams. The boilers were completely rebricked and the emergency fire pump repaired. It was necessary to cast and machine a rear gear train housing for this fire pump. Tests proved the ship seaworthy and the MAZAMA put out to sea.
