DOD-STD-1399 -301A

Abstract

This section is an integral part of DOD-STD-1399. When the interface between the ship motion and attitude and ship structure, systems and equipment is under consideration this section and the standard must be viewed as a single document. The policies and procedures established by DOD-STD-1399 are mandatory. <br>This section establishes interface requirements for ship structure, appurtenances, fittings, machinery, systems, and equipment which are affected by ship motions to ensure compatibility between such ship structure, and so forth, and the effects of ship motion and attitude. <br>The interface which is the concern of this section, and the basic characteristic and constraint categories involved at this interface, are shown symbolically on <a href="#QUZPDAAAAAAAAAAA-X7">figure 1</a> (see definitions of DOD-STD-1399). <a name="QUZPDAAAAAAAAAAA-X7" id="QUZPDAAAAAAAAAAA-X7"><img alt="FIGURE 1. Interface flow chart." /></a> <br>The particular interface characteristics and constraints pertinent to this section are described in 5.2 and 5.3. Values for the characteristics are listed for conventional surface ships and are not applicable to multi-hulls, surface effects ships, and all craft supported principally by hydrodynamic lift. <br>Specific ship motion conditions will be given in the ship design requirements document. <br>Information necessary for the use of this section includes required operational capabilities versus sea state. Ship system and equipment motion limits and calculation methods are presented in this section in <a>table I</a> and the appendix, respectively. Other motion limits or methods may be specified by the invoking document.
