Accesses to the weatherdeck allow crew and equipment to enter and leave areas of the barge and give protection against
adverse weather and sea conditions.
4-1.1 Deckhouse doors and portholes. Deckhouse is fabricated mainly from steel and contains doors and portholes
listed in Table 4-1 and shown in Figure 4-1. Deckhouse is shown in drawings listed in Appendix A. Deckhouse also
provides openings for crew access, void ventilation system, engine ventilation, engine exhaust, and deckhouse
ventilation. Equipment in or on the deckhouse and associated primarily with heating, ventilation, and air conditioning
systems is discussed in TM 55-1930-209-14&P-1 6.

deck for entrance to the voids below. Manhole covers are installed on void 1 starboard. Manhole covers are also
installed on port and starboard sides for access to void 5. Void accesses, doors between voids, and manhole covers are
listed in Table 4-2.
