If a conflict arises between the documents containing the
maintenance procedures for diving equipment and systems, the following actions
are required:
1. PMS/MRC takes precedence.
2. If PMS/MRC is inadequate or incorrect, the applicable military O&M manual
takes precedence. Report inadequate or incorrect PMS via a PMS feedback
report in accordance with current PMS instructions.
3. If PMS/MRC and applicable military O&M manual are inadequate or
incorrect, the manufacturer’s technical manual takes precedence. Report
inadequate or incorrect military technical manual information in accordance
with procedures in the affected technical manual.
Call NAVSEA or NAVFAC prior to disregarding any required maintenance
procedures on certified diving equipment. Failure to do so may compromise
certification.
Diving equipment used to conduct
diving operations shall be authorized for use by NAVSEA/00C Diving Equipment
Authorized For Navy Use (ANU) list or hold a current NAVSEA or NAVFAC
system safety certification certificate. Naval Sea Systems Command (Code
00C3B), Supervisor of Diving is the cognizant authority for the NAVSEA/00C
ANU list. Surface supplied diving systems, hyperbaric chamber systems, and
selected free swimming scuba underwater breathing apparatus shall be certified in
accordance with U.S. Navy Diving and Manned Hyperbaric System Safety Certification
Manual (SS521-AA-MAN-010).
The publication for Continuation of Certification Handbook For U.S. Navy Diving
Systems, (SS521-AB-HBK-010) also provides information concerning maintaining
system certification.
Naval Sea Systems Command Code 00C4
is SCA for all afloat and portable diving and hyperbaric systems. Naval Facilities
Engineering Command Code 00CE is SCA for all shore-based diving and hyperbaric
systems. Naval Sea Systems Command Code 92Q is SCA for submarineemployed
Dry Deck Shelters and one atmosphere diving systems.
Diving equipment shall be maintained in accordance
with the applicable PMS package. Failure to maintain equipment in
accordance with current PMS guidance reduces the equipment reliability and may
void the system safety certification for formally certified systems.
Diving equipment shall not be modified or
altered from approved configuration unless prior written approval has been
granted by the applicable diving equipment technical program manager.
Alterations for shorebased
systems are managed by Naval Facilities Engineering Command (Code
00CE), who is the cognizant technical authority for the development and approval
of alterations to shore-based systems.
The technical program
managers for other diving apparatus are:
-
EX 14 - NAVSEASYSCOM (PMS-395)
-
MK 16 - NAVSEASYSCOM (PEO-MIW)
-
MK 20 - NAVSEASYSCOM (SEA 00C)
-
MK 21 - NAVSEASYSCOM (SEA 00C)
-
MK 25 (LAR-V) - NAVSEASYSCOM (PMS 325)
-
Dry Deck Shelter - NAVSEASYSCOM (PMS 395)
Operating procedures (OPs) are detailed
check sheets for operating the diving system and for performing various systemrelated
tasks. All diving and recompression chamber systems shall be operated in
accordance with a set of NAVSEA or NAVFAC approved operating procedures
(OPs) and Emergency Operating Procedures (EPs) and requires the Commanding
Officer’s or OIC’s signature on the cover page as final review.
Standardized diving equipment such as the Light Weight
MK 3 Surface Supplied Diving System, Transportable Recompression Chamber
System (TRCS), and class-certified equipment such as the MK 16 and MK 25
Underwater Breathing Apparatus shall be operated per a single set of standardized
OP/EPs that are included as part of the system O&M Manual.
Proposed changes/updates to OP/EPs for standardized diving equipment shall be
submitted as a formal change proposal to the respective O&M Manual in accordance
with directions contained therein.
Diving and diving support equipment such as ships,
small boats, and unique shore facility surface supplied diving and recompression
chamber systems shall be operated in accordance with a single set of standard OP/
EPs that are developed at the command level and approved for use after validation
by NAVSEA Code 00C3 or NAVFAC Code 00CE. Proposed changes/updates to
OPs/EPs for non-standardized diving equipment shall be submitted to the applicable
approval authority. The following addresses are provided to assist in
submitting proposed OP/EP changes and updates.
Submit proposed OP/EP changes and updates for afloat, portable diving and
recompression chamber systems, and class-certified equipment to:
COMNAVSEASYSCOM (Code 00C3)
2531 Jefferson Davis Highway
Arlington, VA 22242-5160
Submit proposed OP/EP changes and updates for fixed, shore-based facilities to:
NAVFAC (Code 00CE)
Washington Navy Yard
901 M Street SE, Bldg. 212
Washington, DC 20374-5054
Submission of OPs/EPs for approval (if required) must
precede the requested on-site survey date by 90 calendar days to allow complete
review and resolution of questions. Follow these procedures when submitting
OPs/EPs for approval:
-
The command shall validate in the forwarding letter that the OPs/EPs are
complete and accurate.
-
The command must verify that drawings are accurate. Accurate drawings are
used as a guide for evaluating OPs/EPs. Fully verified system schematics/
drawings with components, gas consoles, manifolds, and valves clearly
labeled shall be forwarded with the OPs/EPs.
-
Approved OPs/EPs shall have the revision date listed on each page and not
have any changes without written NAVSEA/NAVFAC approval.
-
The command shall retain system documentation pertaining to DLSS
approval, i.e., PSOBs, supporting manufacturing documentation, and OPs/
EPs.
The format for OPs/EPs is as follows:
-
System: (Name or description, consistent with drawings)
-
Step, Component, Description, Procedure, Location, Check, Note (read in
seven columns)
-
System: High Pressure Air
-
Step/Component/Description/Procedure/Location /Initials /Note
1. ALP-15/Reducer outlet/Open/Salvage Hold/Initials/Note
2. ALP-GA-7/Reducer outlet/Record Pressure/Salvage Hold/Initials/Note 1
The operator executing the procedure shall initial the Check column. Hazards and
items of particular concern shall be identified in the Note column.
Once NAVSEA or NAVFAC has approved the system OP/EPs, they shall not be
changed without specific written approval from NAVSEA or NAVFAC.
