h. Compressed-air equipment.
(1) An assortment of compressed-air equipment is carried for doing jobs both on and off the ship. This equipment includes rock drills for drilling in rock or concrete; paving breakers used in breaking out concrete, breaking up rock, and in general demolition work; rivet busters for cutting out rivets; woodboring drills for boring various-sized holes in timbers; rotary drills for drilling holes in steel plates and beams; grinders for general grinding; pneumatic hammers for cleaning castings, beveling seams on ships, and chipping holes in concrete; riveting hammers for driving rivets; pneumatic wrenches for tightening and loosening nuts and bolts; nail drivers; chain saws adapted for cutting pilings underwater; and circular saws.

(2) For operating this equipment, there is a 315 cfm, Diesel-driven, skid-mounted air compressor and a 280 cfm, electric-driven air compressor.
i. Beach gear.
(1) The beach gear carried on the ship is used primarily to salvage stranded vessels. This type of salvage differs from raising sunken wrecks, where all the work in preparing the vessel for raising is done by divers. For beach salvage work, divers ordinarily are needed only for examining the stranded vessel’s hull and the nature of the underwater terrain, and beach gear and the towing power of other craft are used to refloat the ship.
(2) The main items of the beach gear are two 8,000-pound anchors, blocks of various types, hooks, clips, chains, manila and wire rope, shackles, cable stoppers, and rope thimbles.

j. Portable salvage pumping equipment. The portable salvage pumping equipment consists of one 10-inch, two 6-inch, and two 3-inch salvage pumps, complete with spare parts, hose, metal suctions, and adapters.

k. Portable fire-pumping equipment. The portable fire-pumping equipment consists of a two-wheeled trailer pumper with a capacity of 500 gpm and four 50-foot lengths of 21⁄2-inch hose.
l. Hoisting equipment.
(1) The hoisting equipment consists of the 40-ton cathead mounted on the prow, one 50-ton and four 10-ton booms on the foremast, and two 5-ton booms on the mainmast, together with the winches for operating them. (See fig. 45.)
(2) The cathead (fig. 46) is used to raise debris and sunken small craft that are hazards to navigation or prevent vessels from coming alongside wharves or piers. It is operated by a two-speed winch installed in the forecastle peak on the shelter deck.
(3) The 50-ton boom is operated by a two-speed winch and the four 10-ton and the two 5-ton booms are run by single-speed winches. (See fig. 47.)

m. Floating equipment. In addition to the life-boats and rafts, the ship carries a steel pontoon barge, a plane-rearming boat, and a utility boat.
(1) The barge is made up of 21 sections (fig. 48) and has a capacity of 50 tons. It is propelled by a 115-hp outboard engine and carries a 5-ton crawler crane for diving and salvage operations. The sections of the barge are stowed in the number 1 hold of the ship.
(2) The plane-rearming boat is 33 feet long and is powered by a 100-hp inboard, Diesel engine. It is used for diving, general utility work, and light towing.
