1.000 SCOPE

This Performance Specification (PSPEC) defines the requirements for the Auxiliary Floating Dry Dock Medium Replacement (AFDM). The AFDM craft will be a floating dry dock capable of conducting Chief of Naval Operations maintenance availabilities for the following ship classes: LCS 1, LCS 2, DDG 51, CG 47, LSD 41, and LSD 49. The AFDM craft will be operated in benign threat environments primarily at Navy Regional Maintenance Centers and will be capable of being relocated to meet future Fleet maintenance requirements. Included in this PSPEC are the mission, capabilities, major systems requirements, interfaces, environmental constraints, and interchange requirements. This specification establishes overall system requirements to guide the Contractor in the subsequent engineering and development of more detailed specifications.

2.000 DOCUMENTS

The following standards and documents are specified in this PSPEC. While every effort has been made to ensure the completeness of this list, the Contractor is required to meet all specified requirements documents cited in this PSPEC, whether or not they are listed in this section. Compliance with referenced documents is mandatory even where the referenced document may use terms similar to “recommendation”, “guideline” or “guidance” in their title or text.

Order of precedence - In the event of a conflict between the text of this document and the references (other than Regulatory Body requirements) cited in this document, the text of this document takes precedence. First tier references take precedence over sub-tier references in the event of a conflict. Nothing in this document shall supersede applicable laws and regulations unless a specific exemption has been obtained. Silence of one document with respect to details or requirements in another document shall not be considered an inconsistency.

Effective issue - Where first tier references, such as Regulatory Body requirements, are referred to, the AFDM craft, as delivered, shall comply with all applicable Regulatory Body requirements in effect at contract award. In addition, the AFDM craft shall comply with all Regulatory Body requirements formally approved by contract award but scheduled for implementation prior to the scheduled delivery of the first craft.

First Tier and Sub-tier Reference - Any referenced document that is directly cited for use or application by an identifying number or name in this PSPEC is a first-tier reference for each particular use or application for which it is so cited. Any document that is cited in a first-tier reference, or in a document referenced therein, is a sub tier reference. A document that is a sub tier reference in one application may also be a first-tier reference in another application when it is cited directly.

In the absence of definitive Regulatory Body requirements, systems and equipment that have single points of failure that degrade the performance of organic mission and safety critical systems shall be provided with compensating features and increased design margins. A single failure point is defined as the failure of an item, which would result in failure of the system and is not compensated for by redundancy or alternative operational procedure. The single failure definition does not apply to the failure of fixed piping, manually operated valves, and duplex strainers.

The AFDM craft will be designed and constructed such that a failure within the craft ballasting system will neither cease its mission intended operations nor cause damage to the AFDM or a ship under service by AFDM.

Material, furnishings and equipment shall be selected by the following criteria:

a. Space functionality

b. Ability to withstand an industrial and marine environment

c. Safety

d. Durability/reliability

e. Maintainability.

Equipment selection should consider existing availability within the Navy and Department of Defense logistics support infrastructure. Materials and applications which ease cleaning efforts and improve facilities maintenance shall be used throughout the craft.

At craft delivery, all machinery and Information Technology hardware shall be delivered with at least five years remaining prior to the Original Equipment Manufacturer’s end of support date.

All application software, including embedded software within systems, and operating systems shall be supportable and provided with the means to be supportable. At AFDM craft delivery, all application software and firmware programs, and operating systems shall be delivered with at least three years remaining prior to the software developer's or Original Equipment Manufacturer's end of support date.

The AFDM craft structure, including interior non-structural bulkheads, shall have a design service life of 50 years. The approach for meeting this design objective shall be a combination of appropriate sizing of scantlings to include a corrosion allowance and effective corrosion prevention systems. Fabrication techniques shall follow the best commercial marine practices.

The AFDM craft docking cycle shall be 10 years. Machinery and equipment shall be located and oriented with all due consideration of access, operation and maintenance. Equipment, outfitting, furnishings, and support systems as well as interior non-structural components such as bulkheads, partitions, deck surfaces, and so forth, shall be selected or designed to minimize upkeep and maintenance.

3.077 ENVIRONMENTAL, SAFETY AND OCCUPATIONAL HEALTH

3.077a GENERAL The Contractor shall incorporate Environmental, Safety and Occupational Health considerations and criteria into the design of craft systems, equipment, and arrangements to ensure the safety of personnel, systems, equipment, and the environment, to ensure regulatory compliance with all applicable environmental laws and regulations.

3.077b SYSTEM SAFETY Install protective guards for machinery and personnel in accordance with OSHA guidelines 29 CFR 1910.
