1 AMSC N/A FSC 1950 INCH-POUND MIL-STD-1625D(SH) 27 August 2009 SUPERSEDING MIL-STD-1625C(SH) 25 August 1987 DEPARTMENT OF DEFENSE STANDARD PRACTICE SAFETY CERTIFICATION PROGRAM FOR DRYDOCKING FACILITIES AND SHIPBUILDING WAYS FOR NAVY SHIPS MIL-STD-1625D(SH) ii FOREWORD 1. This STANDARD is approved for use by the Naval Sea Systems Command, DEPARTMENT of the Navy, and is available for use by all Departments and Agencies of the DEPARTMENT of DEFENSE . 2. The Safety Certification Program (SCP) for drydocking facilities and shipbuilding ways, including transfer facilities, has been established to ensure the safety of Navy ships listed in the Naval Vessel Register that are to be drydocked or built on these facilities.

2 The certification procedures include an evaluation and approval of data associated with the design, material condition, and operation of the facilities. These procedures are described in detail in this Military STANDARD (hereinafter referred to as the STANDARD ). 3. The certification procedures, contents of certification reports, and technical requirements for certification are described in this STANDARD . The scope of the SCP and general certification requirements are provided in sections 1 through 4. Detailed technical requirements are described in section 5. 4. This document is applicable for certifying both Navy-operated and commercially-operated drydocking, building, transferring and launching facilities for ships; but does not necessarily reflect all of the design requirements of dry docks, vertical lifts, marine railways, building and transfer ways or launch ways that are required by new design ship specifications.

3 5. Certification of a facility is based upon the evaluation of the facility data provided by the operating activity. The operating activity remains solely responsible for maintaining and operating the facility in a safe manner and condition. 6. The operator will obtain certification of leased Navy dry docks prior to docking Navy ships. The Navy is not responsible for providing or preparing certification data. Certification of the dock is not required for docking non-Navy ships. 7. Training programs will ensure that dry dock personnel are adequately qualified to perform their assigned functions and that every person has a sound knowledge of how their workstation interacts with others.

4 Training programs will also provide for qualified personnel to periodically review the responsibilities of their workstations, and for retraining or re-qualification whenever new procedures or operations are introduced. 8. Where terms are used herein such as submitted, submitted to the Navy, provided to the Navy, or made available for Navy review, the recipient is intended to be: a. The Naval Sea Systems Command (Logistics, Maintenance, and Industrial Operations Directorate (SEA 04)) when a Navy shore or fleet activity is submitting the certification report for its own drydocking facility.

5 B. The cognizant Supervisor of Shipbuilding (SUPSHIP), Regional Maintenance Center (RMC), or other designated Navy representative, when a Navy contractor is submitting the certification report for its own or leased drydocking facility. 9. Comments, suggestions, or questions on this document should be addressed to Commander, Naval Sea Systems Command, ATTN: SEA 05B5, 1333 Isaac Hull Avenue, SE, Stop 5160, Washington Navy Yard DC 20376-5160 or emailed to with the subject line Document Comment.
