Weapons Onload/Offload There are three situations in which weapons onload or offload operations are normally conducted-pier side, offshore at anchorage, or at sea. The location of the ship during onload or offload operations affects manpower, equipment, time, and the degree of safety requirements. PIER SIDE.— Handling large quantities of explosive munitions at piers is limited to those designated by NAVSEASYSCOM as “explosive piers.” The pier area is restricted during ammunition and explosive loading and offloading operations. Nonessential personnel (visitors) aren’t permitted access to the ship or pier area. All privately owned vehicles, ship’s vehicles, and assigned government transportation are prohibited on a pier where ammunition is being handled. Before loading or offloading operations, the OOD is notified. The OOD makes sure that a red flag is prominently displayed to indicate that an ordnance evolution is in progress. Pier-side ammunition handling operations are restricted to daylight hours, except in an emergency. Emergency operations can only be carried out at an adequately lighted pier. An emergency maybe dictated by the ship’s sailing schedule or by NAVSEASYSCOM. Therefore, ammunition isn’t staged on the pier in large quantities. Close coordination is established between the ship’s weapons department and the station’s weapons department to ensure that the rate of delivery at the pier doesn’t exceed the handling rate of the ship’s ordnancemen. EXPLOSIVE ANCHORAGE.— At times, loading or offloading large quantities of ammunition and explosives at the pier is not practical or feasible. For example, a ship may be located at a pier that has a restricted explosive load limit due to the geographical location of other ships or occupied structures. It could A1. A2. A3. A4. A5. A6. A7.

A movable ramp is used to bridge the gap in the door opening between an elevator platform and the deck. If an elevator suspension rope breaks, a broken-rope safety device automatically operates to lock the platform to the guide rails. If an elevator overtravels upward beyond the maximum up-stage position, an overtravel limit switch actuates, stopping the elevator and shutting off power to the hoisting winch. Upper-stage elevators are used to transport weapons between the 2d and main decks. The 7th through the main decks are serviced by IWHS lower-stage elevators. The platform machinery for an IWHS lower-stage’ elevator is located on the 3rd deck. The only weapons elevators that provide access to the flight deck are the upper-stage, wire-rope elevators. The primary responsibility for maintaining weapons elevators belongs to the AO rate. The electrical power required to operate the weapons elevators is 440-volt, three-phase, 60-Hz power. 11-30
