Engineering Support

Engineering Support Requests

Identifies tasks for Engineering Support Services specifically requested by the Defense Logistics Agency (DLA) or NAVSUP Weapon Systems Support (NAVSUP WSS) Mechanicsburg from NAVSEALOGCEN per the Navy-DLA Performance Based Agreement, NAVSEAINST 4408.3A/NAVSUPINST 4408.5A and the NAVSEA-NAVSUP Engineering Support Performance Based Agreement.

Engineering Support Services include DLA form 339 Engineering Support Requests, Navy Technical Referrals, or other DLA or NAVSUP WSS approved and documented technical requests. NAVSEALOGCEN conducts initial processing of Engineering Support Requests and Technical Referrals for Hull, Mechanical and Electrical (HM&E) equipment per a Memorandum of Understanding (MOU) between NSWC Philadelphia Division (NSWCPD) and NAVSEALOGCEN. Engineering Support Requests and Technical Referrals allow for the update of technical data when necessary, and resolve issues such as obsolescence and incorrect or outdated provisioning data.

NAVSUP WSS assigns and routes Engineering Support Requests and Technical Referrals electronically to NAVSEALOGCEN and other In-Service Engineering Agents in the Engineering Support Request System (ESRS).

Additionally, NAVSEALOGCEN maintains the associated IT Systems used to create, review, and work Engineering Referrals and to create, review and approve Technical Data Packages for the development of procurement contracts.

Level 1/SUBSAFE/DSS-SOC Functional Audit Support

The Submarine Safety (SUBSAFE) Requirements Manual, NAVSEA 0924-62-0010, implements the SUBSAFE Program and charges NAVSEA 07 with ensuring compliance to all SUBSAFE requirements. The System Certification Procedures and Criteria Manual for Deep Submergence Systems, NAVSEA SS800-AG-MAN-010/P-9290, implements Deep Submergence Systems (DSS- SOC) Program and charges NAVSEA 07 with ensuring compliance to all DSS requirements.

Verification of compliance to all SUBSAFE and DSS requirements is accomplished by NAVSEA 07Q via the Functional Audit process.

NAVSEALOGCEN supports NAVSEA 07Q in performing SUBSAFE and DSS Functional Audits of Shipyards, Warfare Centers, and other Commands that support the SUBSAFE and DSS Programs. In addition, NAVSEALOGCEN attends biannual SUBSAFE and Level I Material Identification and Control Working Group meetings and the biannual Deep Submergence System Host Ship Working Group meetings.

SUBSAFE Certification Audit Support

The SUBSAFE Requirements Manual, NAVSEA 0924-62-0010, implements the SUBSAFE Program and charges NAVSEA 07 with ensuring compliance to all SUBSAFE requirements. Verification of compliance to all SUBSAFE requirements in order to certify a submarine as SUBSAFE for Unrestricted Operations (URO) is accomplished by NAVSEA 07Q via the SUBSAFE Certification Audit process.

NAVSEALOGCEN supports NAVSEA 07Q in performing SUBSAFE Certification Audits of Pre-Commissioned Units (PCU) managed by PMS 450 and In-Service submarines managed by PMS 392 and PMS 396.    

DSS-SOC Engineering & Technical Support

NAVSEALOGCEN provides engineering and technical support for the maintenance and overhaul of critical systems on submarines and surface ships via technical oversight of the Deep Submergence Systems Stock Program managed by NAVSUP WSS N97.

DSS-SOC Engineering Support duties:

• Respond to engineering and procurement referrals to adjudicate technical issues with critical supply system material.
• Provide engineering oversight of the Portsmouth Naval Shipyard Receipt Inspection Activity
• Support NAVSUP WSS in vendor qualification audits to expand and maintain the DSS-SOC supply base
• Provide general technical and quality support to the NAVSUP WSS DSS-SOC Stock Program
• Process and maintain Approved Engineering Alternatives (AEAs) and Approved Engineering Changes (AECs) related to DSS-SOC stock material for fleet reference
• Review and approve Technical Data Packages for the development of NAVSUP WSS Level I/SUBSAFE/DSS-SOC procurement contracts.

MBPS Readiness Cell Development and Support

The Model Based Product Support (MBPS) program seeks to rationalize, integrate, and field a modern cloud-based digital logistics IT infrastructure for the Navy. NAVSEALOGCEN supports NAVSEA and the MBPS effort with the development of a Navy Common Readiness Model (NCRM); an integrated modeling and simulation-based approach to supportability analysis.

NAVSEALOGCEN support related to NCRM will include the performance and transition to NCRM for modeling Readiness Based Sparing. Further work will include supporting the development, processes and instruction updates as required for the MBPS solution, participating in user group knowledge sharing, and participating in Data Requirements and Definitions required for solutions.

Readiness Based Sparing Planning and Management

Guided by OPNAVINST 4442.5B, Readiness Based Sparing (RBS) models make system sparing and repair parts allowance determinations by optimizing readiness thresholds and costs.

NAVSEALOGCEN uses the Navy Common Readiness Model (NCRM) to execute RBS models that provide valuable information for a systems development and sustainment throughout its lifecycle, from initial provisioning to replenishment support.

RBS reports include boundary of models, configuration profiles, mission provides, part files, RBS curves with target Operation Availability (Ao), RBS Models, and Reliability Block Diagrams (RBDs).

NAVSEALOGCEN also provides technical management and model validation support to the Maritime Allowance Readiness Based Sparing, Reprovisioning and Change Review Board (MARRC-RB).

Reliability, Availability, and Maintainability (RAM) Planning and Management

Achieving specified levels of RAM for a system is important for many reasons; specifically the affect RAM has on readiness, system safety, mission success, total ownership cost, and logistics footprint.

RAM analysis includes modeling and conducting simulations of factors to determine impact to Operational Availability (A_O), Material Availability (A_M)_, and cost.

Reliability is the probability that a system will perform a required function under stated conditions for a specified period. Reliability is comprised of mission reliability and logistics reliability.

Availability is a Key Performance Parameter (KPP) required for all Navy programs; expressed as uptime/uptime + downtime.

Material Availability (A_M) - the percentage of the total inventory of system operationally capable of performing an assigned mission.

Operational Availability (A_O) - the percentage of time that a system or group of systems within a unit are operationally capable of performing an assigned mission.

Maintainability measures the ease and speed of system restoration after a failure. Factors in determining maintainability include the skills of maintainers, procedures, and the level of repair.

RAM reporting includes spreadsheets and histograms of simulated results from MCRM (OPUS) modeling and Failure Reporting, Analysis, and Corrective Action System (FRACAS) reports.

Provisioning

NAVSEALOGCEN personnel review vendor furnished information to ensure it meets contractual and policy requirements and us it develop provisioning packages for upload to systems of record.

If data is insufficient or conflicts identified, personnel work with Program Offices, Shipbuilders, and manufactures to resolve.
