hi CHAPTER V, SECTION 1 Maintenance of marine equipment on loan from the U.S. Navy was also a prime responsibility of the Contractor. In addition, work was accomplished on Army, Navy, and Air Force small craft on specific Maintenance Work Orders. LCM craft and Water Taxis were given a thorough inspection and oil change every 100 hours of operation and were beached only when it was necessary for on-shore repair work. LCU craft were maintained by the crew assigned to the craft, except for major repairs. Operators allowing eight fuel pumps or fuel injectors to be tested at one time. In addition to the marine repair facilities on Elmer, a Marine Repair Shop was established at Nan to serve the small craft assigned to Bikini Atoll. Plans were formulated for beaching all small craft at Site Elmer not required during the interim period. LCM’s were thoroughly reconditioned, with engines being removed and overhauled before being placed in storage. of all small craft were charged with keeping an accurate record of engine hours of operation. The anticipated operating time of marine engines between overhauls was set at 3500 hours, based ROADS AND AIRSTRIPS. were Road maintenance was continuous at all sites. On Elmer, roads were frequenty graded Maintenance repairs were largely confined to engines, bottom and hull plating, replacement were constantly cut up by the movement of track-type equipment and required continual recompaction as well as grading. On Fred the on Navy standards; however, engines usually removed and overhauled after every 3000 hours of operation. of stringers and stiffeners, and replacement or repair of propellers and shafts. To accomplish these repairs, small craft were beached by use and watered to reduce dust nuisance. Roads along the water front and in the warehouse area surfaced roads required spot repairs as a result of damage caused by heavy vehicular traffic, particularly following a dearth of rain. Road of a “Gilhoist” rig or placed in a floating drydock. Ramp winches and winch clutches required frequent maintenance due to continual usage, work on Nan andthe off-island camps was constant, requiring much grading and recompaction winches were standardized to utilize like parts. Following the rehabilitation of the airfields, maintenance work at these installations was sweeping, re-marking, and clearing brush and and a supply problem arose because of the fact that the LCM craft in use were of three different tvpes; however, through modification, all LCM Some bottom plating was required on barges used for lighter service. Chipping, painting, and plating were performed continuously on all craft. One of the most modern pieces of test equipment—-for the testing and adjustment of fuel pumps and fuel injectors—was available in the Marine Equipment Repair Shop on Elmer, because of the damage inflicted by the movement of heavy construction equipment. other obstacles from the strips. Some electrical maintenance was necessary at those airfields which were equipped with night-lighting facili- ties. Both airfields and helicopter pads required infrequent replacement of the wind socks. Most of the maintenance on the Fred Airfield was (Neg. No. W-610-10) Figure No. 5-4.
