1. Purpose
a. To establish waterfront engineering and technical authority policy for Naval Shipyards,
Supervisors of Shipbuilding (SUPSHIP), the Keyport Torpedo Depot, Regional Maintenance
Centers (RMC), and other fleet maintenance activities. This instruction is consistent with
references (a) and (b) and supports programmatic authorities in providing best-value engineering
and technical products to the fleet.
b. To define the responsibility, accountability, and authority of Naval Shipyard, SUPSHIP,
the Keyport Torpedo Depot, and RMC Chief Engineers (CHENG), hereafter referred to as
Waterfront CHENGs, for engineering and technical decisions within the scope of this instruction
and for the exercise of that authority by their assigned activities.
c. To establish the Waterfront CHENG as the point of entry for all technical matters within
their assigned activity/activities.
d. To establish a formal engineering change policy where a permanent change in the design
of a ship, system, or component, or an alteration executed via a ship change document (SCD), is
required.
e. To establish a formal departure from specification (DFS) policy whereby conditions
onboard ships that are not in compliance with Naval Sea Systems Command (NAVSEA)
requirements must be technically dispositioned by the applicable technical authority. This
instruction provides the NAVSEA policy on evaluation and adjudication of DFSs.
