In case of a conflict between the MPC, NEM, and NSTM, which has the highest precedence?

The Merchant Publication Catalogue (MPC) is the authoritative source when it comes to policy and procedural guidance within the Navy. It is specifically designed to standardize operations across various technical and engineering tasks, making it a primary reference for personnel. In situations where there is a conflict between the MPC, the Naval Engineering Manual (NEM), and the Naval Ship’s Technical Manual (NSTM), the guidelines outlined in the MPC take precedence due to its comprehensive nature and the authority it holds in establishing operational standards.

The NEM and NSTM serve important roles as well, but they are typically subject to the overarching instructions and policies defined in the MPC. Therefore, when conflicts arise, it is essential to adhere to the MPC to ensure compliance with the Navy's established protocols and procedures. This structure helps maintain consistency and reliability in naval operations, aligning with the need for standardized technical references.
