JOINT FLEET MAINTENANCE MANUAL

COMFLTFORCOMINST 4790.3 REV A
f. Ship Drawing Index (SDI). The SDI lists all drawings for a class of ship. Using the SDI is the only
way to determine a drawing's applicability. In addition to drawing applicability, it provides drawing
revision applicability and TVD applicability. The SDI will also identify whether a drawing contains
Submarine Safety (SUBSAFE) information, Noise Control information or is an SRD.
3.6.2 Unrestricted Operations Maintenance Requirement Cards (Submarines only).
a. Reference (ac) establishes the maintenance requirements and identifies the responsibilities and actions
required to support continued unrestricted submarine operations to design test depth. This program is
invoked on all SUBSAFE certified submarines. To support this program the Ship Program Manager
issues individual manuals containing required, periodic SUBSAFE maintenance actions for each class
and in some instances particular ships.
b. Loadout of Unrestricted Operations (URO) MRCs will be accomplished in conjunction with PMS
installation. SUBMEPP representatives will provide to the ship's 3-M Coordinator the ship's copy of
the "URO Book" during Phase II PMS installation. SUBMEPP manages the URO program for
submarine Program Managers.
c. Additional information concerning the URO program can be found in Volume VI, Chapter 25 of this
manual.
3.7 OPERATIONAL CONTROL TRANSFER. OCT, depending on the platform, will happen in one of several
ways. The entire ship is turned over at one specific time (ship custody transfer), compartments/spaces are turned
over as completed, or systems are turned over as completed without regard to space completion.
a. The shipbuilder will:
(1) Ensure all testing is complete to the most practical extent possible.
(2) Provide Ship's Force and the Supervising Authority with a turnover schedule.
(3) Conduct a review of all existing work/deficiencies with Ship's Force and the Supervising
Authority and determine those items that must be cleared or resolved to support a safe and
operational system turnover.
(4) Verify system, space or ship ready for turnover.
(5) Conduct walk-through with Ship's Force.
(6) Execute turn-over.
b. Ship's Force should be prepared to:
(1) Provide system experts for walk-throughs.
(2) Address concerns regarding turn-over to the Supervising Authority's Ship Manager.
(3) Ensure all work/deficiencies are cleared or resolved to ship's satisfaction prior to acceptance.
