A Sequence of Events Leading to System Certification and Sea Trials

B Sample Phase II Crew Certification Agenda for DSVs/DSRVs

5.1 PURPOSE. To provide guidance in the recertification requirements of references (a) through (d) for Deep Submergence/Rescue Vehicles completing Operating Cycle maintenance. Information concerning the maintenance and certification of Diver Life Support Systems, Submarine Rescue Chambers and Dry Deck Shelters is addressed in Volume IV, Part III, Chapter 12 of this manual.

5.2 DEEP SUBMERGENCE VEHICLE/DEEP SUBMERGENCE RESCUE VEHICLE MAINTENANCE STRATEGIES. The Deep Submergence Vehicle (DSV)/Deep Submergence Rescue Vehicle (DSRV) maintenance strategies involve a number of short to medium length Restricted Availabilities (RAVs) between extended major maintenance availabilities which occur concurrently with mandatory 60 month hull surveillance for DSVs and 72 months for DSRVs. Even with this difference in maintenance strategies the similarity in systems and procedures is such that the provisions and intent of submarine trial requirements have been incorporated for DSVs/DSRVs wherever possible. Mandatory recertification procedures have been incorporated into Sea Trial requirements for DSVs/DSRVs presented in this chapter.

5.3 PROCEDURES.

5.3.1 Restricted Availabilities Two Months Duration or Less.

a. No requirements are invoked for crew certification, Fast Cruise or Sea Trials. Should the Officer In Charge (OIC) determine that alterations/repairs accomplished or personnel transfers warrant time for crew training, a formal request shall be submitted to the Type Commander (TYCOM), via the Commander, Submarine Development Group (COMSUBDEVGRU) ONE, requesting training time be allowed following completion of the availability.

b. Dock Trials are limited to testing of those equipments/systems repaired, disturbed or altered during the availability. Dock Trials for DSVs/DSRVs will be conducted "wet" in the Deep Submergence Unit (DSU) Test Pool or on a tethered or captured lift system (i.e., support ship).

c. Availabilities of this duration will not normally encompass work of sufficient scope to require an on-site survey by the Naval Sea Systems Command (NAVSEA) System Certification Authority (SCA). However, if work performed during the availability warrants an on-site survey to verify that system certification has been properly sustained during the availability or to authorize a continuance of system certification, the procedures of paragraph 5.3.2.g of this chapter apply.

d. The Fleet Maintenance Activity (FMA)/industrial activity shall provide the DSV/DSRV with written verification that all repairs have been completed in accordance with specifications. References (a) and (b) contain the specific requirements for the areas that must be addressed by the written verification.

e. The OIC of the DSV/DSRV shall provide written verification to COMSUBDEVGRU ONE, with an information copy to TYCOM, that all repairs completed by Ship's Force have been completed in accordance with applicable specifications.

f. The OIC of the DSV/DSRV shall send a message to COMSUBDEVGRU ONE with an information copy to TYCOM, that the RAV has been completed and that the unit is fully ready to assume operational duties.

5.3.2 Restricted Availabilities Greater Than Two Months but Less Than Six Months Duration. The following requirements are invoked and time for these evolutions shall be included in the availability schedule.

a. Dock Trials will be conducted in accordance with paragraph 5.4.3 of this chapter.

b. No requirements are invoked for crew certification and availability time will not be allocated for this function. Should the OIC determine that alterations accomplished or personnel transfers warrant crew certifications, a formal request must be initiated. Requests will be addressed to the TYCOM, via COMSUBDEVGRU ONE. The activity accomplishing the availability is requested to advise the TYCOM what adverse effects crew certification will impose upon the availability schedule.

c. The FMA/industrial activity shall provide the DSV/DSRV with written verification that all repairs have been completed in accordance with specifications.

d. The OIC of the DSV/DSRV shall provide written verification to COMSUBDEVGRU ONE, information copy to the TYCOM, that all repairs completed by Ship's Force have been completed in accordance with applicable specifications.

e. Fast Cruise will be conducted in accordance with paragraph 5.4.4 of this chapter. Reduction in the scope of Fast Cruise may be granted by COMSUBDEVGRU ONE where warranted by the scope of work performed or the state of crew training.

f. Sea Trials are required only as necessary to test work completed during the availability. As a minimum this will include one dive to test depth. The industrial activity and Ship's Force shall develop the Sea Trial Agenda and submit it to COMSUBDEVGRU ONE for approval, information copy to the TYCOM. Extension of the Sea Trial period may be granted when warranted by the scope of work accomplished or the inability to conduct the trials because of prohibitive weather or support ship non-availability. Requests for the extension of Sea Trials due to scope of work accomplished, which will require a change in the availability schedule, must be submitted to the TYCOM as early as practical. Extensions due to weather or support ship non-availability may be granted by COMSUBDEVGRU ONE.

g. Availabilities of this duration will normally encompass work of sufficient scope to require an on-site survey by the NAVSEA SCA to verify that system certification has been properly sustained during the availability or to authorize a continuance of system certification. At least six weeks prior to the scheduled availability completion date, COMSUBDEVGRU ONE will request, via the TYCOM, that NAVSEA perform the on-site survey. Survey deficiencies will be categorized in accordance with reference (a). All Category IA deficiencies must be corrected, and corrective action approved by the NAVSEA SCA and applicable Program Office prior to Fast Cruise. The TYCOM will provide a final clearance report to COMSUBDEVGRU ONE for all survey deficiencies originated by the TYCOM or higher authority.

(1) If the scope of work is of sufficient magnitude to require recertification of the DSV/DSRV, system certification and Sea Trials shall be accomplished in accordance with Appendix A of this chapter except for crew certification. Crew certification is a personnel training and administrative procedure rather than a material procedure and is not required for an availability of less than six months unless specifically requested by the OIC.

(2) If the scope of the work is not of sufficient magnitude to require recertification, Dock Trials, Fast Cruise and Sea Trials shall be accomplished in accordance with events 3, 5 through 9, and 16 through 20 in Appendix A of this chapter. Event 5 in Appendix A of this chapter will be conducted by the Immediate Superior in Command (ISIC).

5.3.3 Restricted Availabilities/Major Maintenance Periods Greater Than Six Months Duration.

a. Appendix A of this chapter outlines the sequence of events leading to system certification and Sea Trials for DSVs/DSRVs. Availabilities of this duration will include maintenance/alterations of sufficient scope to require system recertification.

b. In addition to overall crew certification, there are specific individual qualifications for assigned DSV/DSRV operators and Navy divers. Requirements for certification and maintenance of certification for DSV/DSRV operators are promulgated by DSU Instructions. Requirements for maintaining Navy diver qualifications are set forth in reference (b). It is the responsibility of the OIC of assigned individuals to maintain qualifications during extended availabilities.

5.4 CREW CERTIFICATION/DOCK TRIALS/FAST CRUISE. Appendix A of this chapter lists the sequence of events from the beginning of major maintenance through system recertification. The remainder of this section offers supplementary information concerning the events.

5.4.1 Crew Certification.

a. DSV/DSRV crew certification consists of two parts.

(1) Phase I is as stated in reference (c).

(2) Phase II will consist of an inspection of the vehicle on board the surface support ship. This inspection will assess the ability of the crew to perform under simulated underway conditions, emphasizing emergency drills both on the submersible and the support ship. Phase II will include tethered launch and recovery of the vehicle and a tethered dive, if feasible, not to exceed a depth of one foot of water above the upper hatch, as directed by the senior board member, (waiver of a tethered dive must be approved by the TYCOM). Phase II Crew Certification will be conducted after all Category IA survey deficiencies have been corrected in accordance with paragraph 5.3.2.g of this chapter and prior to Fast Cruise. Appendix B of this chapter provides a sample Phase II Crew Certification Agenda and delineates the normal composition of the inspection team.

5.4.2 Manned Dives/Testing for Deep Submergence Vehicles/Deep Submergence Rescue Vehicles in Pursuit of Certification (or Recertification).

a. DSVs/DSRVs nearing RAV or major maintenance period completion must often conduct manned dives/testing while in pursuit of certification (or recertification). The DSV/DSRV OIC shall take the following action prior to commencing any and all manned dives/testing of systems which are in pursuit of system certification (or recertification).

(1) Manned Testing - System Dry (Closed Boat). The OIC shall ensure the applicable portions of paragraphs 5.4.2.a.(2) of this chapter are assessed for impact on planned testing (no report required).

(2) Manned Dives/Testing - System Wet (Tethered and in the pool as DSU or tethered import (e.g., LANEY CHQUEST) or on a captured lift system at sea (e.g., DOLORES CHQUEST). The OIC shall submit a written request to COMSUBDEVGRU ONE (information copies to the TYCOM and NAVSEA SCA) containing the following:

(a) If the internal survey or NAVSEA SCA survey has been accomplished, provide an impact assessment for any open Category IA deficiencies.

(b) Identify any outstanding deficiencies that may impact dives/testing.

(c) Identify all open Re-Entry Control documents and provide an evaluation of the impact of these Re-Entry Control documents on planned dives/testing.
