SAFETY CERTIFICATION PROGRAM FOR

DRYDOCKING FACILITIES AND SHIPBUILDING WAYS

FOR U.S. NAVY SHIPS

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 U.S. Navy ships listed in the Naval Vessel Register that are to be drydocked or built on these facilities. 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.

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 U.S. Navy dry docks prior to docking U.S. 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. 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.

b. The cognizant Supervisor of Shipbuilding (SUPSHIP), Regional Maintenance Center (RMC), or other designated Navy representative, when a U.S. 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 CommandStandards@navy.mil, with the subject line “Document Comment.” Since contact information can change, you may want to verify the currency of this address information using the ASSIST Online database at http://assist.daps.dla.mil.

1. SCOPE

1.1 Scope of the safety certification program (SCP). The scope of the SCP is as follows:

1.1.1 Purpose. The purpose of the SCP is to ensure the safety of U.S. Navy ships during docking and undocking operations, while in dock, while under construction, and during launching and transfer operations. The designed capacity of the drydocking facility is to be determined, as well as its current material condition with regard to its foundations, structure, and supporting auxiliary systems, including those for ship protection. Also included is an assessment of operating procedures, manning and personnel qualification procedures, and maintenance procedures supporting operational reliability.

1.1.2 Limitations of SCP scope. There are many applicable federal and state laws, as well as ordinances and regulations; compliance in these areas may be under the cognizance of other Government agencies. The scope of the SCP excludes the following:

a. Personnel safety. Requirements of agencies, such as the Occupational Safety and Health Administration (OSHA). Radiological controls are to be implemented using separate programmatic requirements.

b. Mechanical handling system. Safety requirements in the design and operation of equipment such as cranes.

c. Service systems. Facility subsystems that are installed solely to provide habitability and housekeeping services to the ship, such as potable water and steam for heating and galley. The facility subsystems, such as raw and salt water and compressed air, are included in the scope of the SCP to the extent that they support ship protection systems.

d. Industrial systems. Systems used in industrial services, such as welding or abrasive blasting.

e. Labor and environment. All labor and environmental issues, such as those required by the Department of

Labor and the Environmental Protection Agency, including hazardous material issues and pollution control systems.

4. GENERAL REQUIREMENTS

4.1 General. This section provides an overview of the SCP general requirements for certification of drydocking facilities and building ways, as well as operation of certified facilities.

4.2 SCP overview. The SCP is described in 4.2.1 through 4.2.9.

4.2.1 Certification process. The certification process is initiated by submission of an FCR to the Navy by an operator. Based on an evaluation of the data submitted and an on-site pre-certification inspection including operational tests, the Navy decides whether or not to certify the facility and so advises the operator. Requirements for the format and contents of an FCR are described in Appendix A. These requirements include historical data, design data, maintenance procedures, manning and operating procedures, material condition survey results, and proposed repairs. If the Navy’s pre-certification inspection and review of the FCR supports certification, a facility certification will be issued stating the maximum docking capacity for which the facility is certified, loading limitations, duration of the certification period and the conditions for sustaining certification.

4.2.2 Maintenance program. All activities shall implement a maintenance program prepared in accordance with 4.9 and shall demonstrate during Navy audits that the facility is properly maintained and operated.

4.2.3 Key items in certification capacity, limitations, and duration. Capacity, limitations, and duration shall be as follows:

4.2.3.1 Certified rated capacity. This capacity is the maximum allowable displacement for a Navy ship on a certified facility. Facilities shall be described by total displacement in long tons, and by allowable line loading, such as tons per unit length, or area loading, such as tons per square foot.

4.2.3.2 Operational limitations for a particular ship docking, building, transferring, or launching. In conjunction with the CRC, the Navy may impose additional operational limitations on a certified facility to ensure the safety of the ship.

4.2.3.3 Sustaining certification. All activities shall implement a maintenance program in accordance with 4.9.

The activity shall demonstrate that the facility is satisfactory to sustain certification during Navy maintenance audits and inspections. The Navy may require certain facility repairs or modifications to be completed within a specified time frame as a condition for sustaining certification. The Navy retains the right to inspect the facility at any time.

4.2.3.4 Certification period. The certification period is the duration for which certification remains valid.

4.2.4 Changes affecting certification status. Changes affecting certification status are as follows:

4.2.4.1 Policy. The Navy reserves the right to suspend or cancel a facility’s certification or to alter it by revising items listed in 4.2.3.1 through 4.2.3.4 under any one of the following conditions:

a. The facility is damaged or significantly altered to such an extent that safety is impaired or the physical dimensions are modified.

b. New information emerges that shows that the facility is unsafe.

c. Conditions described in 4.2.3.1 through 4.2.3.3 are violated.

d. Manning or operating procedures specified in the approved FCR are violated.

e. The reporting requirements of 4.2.6 are not met.

f. A qualified Facility Operations Supervisor is not available, see 4.2.7.

4.2.4.2 Suspension and rescission of certification. Suspension is a temporary revocation of certification;

rescission is a final revocation of certification. The Navy will advise a facility operator if it determines that there is cause to suspend or rescind certification. Certification will be rescinded when the operator fails to comply with certification requirements for a period of more than a year following suspension of certification. After certification is rescinded, reinstatement of certification will require the submission of a new FCR.

4.2.4.3 Suspension of certification. Certification will be suspended if a facility is moved from the site where it was originally certified or if it undergoes major repairs or modifications.

4.2.4.3.1 Suspension of certification of a moved facility. If a facility is moved from its certified site, it will be suspended from the time it is moved until it is relocated to a site that has been approved by the Navy. The following shall apply:

a. If a facility is moved and is returned to its approved site, a post-transit hull inspection shall be conducted, with the results submitted to the Navy for review and approval. In addition, an operational test witnessed by the Navy, including a submergence test to the maximum dock draft, shall be conducted prior to reinstatement of certification.

b. If a facility is relocated to a new site, certification data for the new site shall be submitted to the Navy for approval prior to reinstatement of certification. This data shall include the following: a post-transit hull inspection, an operational test including a submergence test to the maximum dock draft and a revision to the FCR. Examples that require a revision to the FCR include, but are not limited to, changes in manning procedures and personnel qualification criteria, operating procedures, protection of a ship during the lay period, electrical power systems, communications systems and alarms, mooring and anchoring, fire protection systems, and hydrographic survey.

4.2.4.3.2 Suspension of certification of a repaired or modified facility. Certification will be suspended from the commencement of a major repair or modification until Navy approval of a post-repair report. A major repair consists of repairs to the extent that a facility will be out of operation for over 90 calendar days. A major modification consists of altering the baseline certification to such an extent that the certified capacity is changed or the physical dimensions of the facility are modified. A post-repair report shall be submitted to the Navy for approval and shall confirm the following:

a. The mate
