Material on Habitability Improvement Program Drawings are identified by Find Numbers. The Find Number Catalog (FNC) posted here lists all of the Find Numbers in a searchable form. The complete unique Find Number (FN) consists of the Find Number and Discipline, such as FN 518 ARR. The primary disciplines are Arrangement (ARR), Electrical (ELEC), Pipe (PIPE) and Ventilation (VENT).
The FNC is a parts catalog that has been refined over the decades using standardized descriptions which can be invoked across different drawings. This standardization improves efficiency throughout the design and supply cycle as well as enabling the establishment of long-term procurement contracts to leverage production line manufacturing with consistent high-quality products. The FNs are defined to suit modular procurement and installation, and take into account features to suit efficient installation.
More detail:
Many of the major vendors for Shipboard Habitability materials are familiar with FNs, and recognize a FN as a complete description. Other activities are encouraged to use and interface with the FN system as a common parts catalog in order to encourage standardization and efficient ordering and administration of materials.
Descriptions are updated regularly to reflect changing specifications and industry trends, with care to ensure compatibility between existing material, and current and future drawings. If a FN needs to change so much that it would no-longer be interchangeable, then a new FN is established and the original FN is archived. The posted FN descriptions are also used as Contract Line-Item descriptions. Standardized amplifying Notes are used as an additional part of the specification in requisitions and contracts.
