The information covered by this standard is intended for use on early stage machinery arrangements development. The information will be used to design and validate the sizes and locations of the following areas (including, but not limited to): machinery boxes, shafting, intakes and uptakes, and major machinery (such as engines, motors, reduction gears, propulsors, rudders, and their associated equipment).

Naval ship machinery arrangement design practices differ from commercial ship design practices in order to account for the potential hazards encountered in military service and in considerations for battle damage and mission essential system reliability.

The information provided in this standard is to be used by machinery arrangements engineers to design or validate on a ROM scale. Guidelines and information provided will generally be used to design and validate during early phases of design. The intent is to ensure that provisions are made to account for the space reservation and location of various elements and systems.

The standard is not intended to be a complete system design guide. It will not be used to size or locate every piece of a system, but rather the system as a whole.
