The SDRL Codes and their definitions are shown in Table I.


The Seller shall comply with the procedures, perform the tests and provide the documentation required by the SDRL Codes shown on the purchase order. The SDRL Codes required for each of the Buyer’s catalog numbers on the purchase order are identified by the four digit alpha-numeric code contained on the Sample Purchase Order shown on Figure 1. The description of the tests and documentation required for each SDRL Code is provided within this appendix on the following pages. Most SDRL Code requirements include documentation submittals. Submittals shall be made to the Buyer’s Documentation Center utilizing a transmittal letter as a cover sheet in accordance with Figure 2. Documentation for only one SDRL Code shall be submitted with each transmittal letter. Specific submission instruction is provided with the applicable SDRL Code description.

New SELLER Requirement as of Appendix G, Revision R, dated 04/05/2019


From this point forward all VFI shall be transmitted electronically via the NIIIP-SPARS VES. If you have any questions regarding submittals please contact the VFI Coordinators:

Please contact the BUYER VFI/VES Administrator at 207-442-5231 to establish your company VES Administrator.

The BUYER at Bath Iron Works has deployed an Internet based application to assist in managing the VFI process. This Internet application developed by a consortium of shipbuilders, suppliers and IBM is called NIIIP-SPARS (National Industrial Information Infrastructure Protocols – Shipbuilding Partners and Suppliers) and was sponsored by the US Navy through the NSRP (National Shipbuilding Research Project). IBM Global Services hosts these applications as well as other applications on secure servers called a Virtual Enterprise Server (VES), accessible by user ID and Password coupled with a shipyard feature to enable users in the process as well as specific ship construction programs.

SPARS applications are web-based and require the user to have a PC with a Microsoft Internet explorer web browser version 5.5 or greater. The SELLER shall note that the address for the site when provided is prefaced with https. All data transmitted to and from BUYER is encrypted and meets or exceeds FIPS 140-1 standards. The SELLER has access to all data they create and transmit to and from the SPARS VES however they do not have access to any other supplier’s data. The SELLER may also access the status of their data at all times via the web browser. User ID and password authentication is required to gain access to the site and users are challenged to regain access after 15 minutes of idle time. An embedded user guide is provided with specific examples on how to use the system or one-on-one guidance can be provided at your request by contacting the numbers listed below.

SPARS participation is by Invitation Only. This means that the BUYER needs to initially “invite” a SELLER to participate in the process. The BUYER VFI Coordinator who notifies the BUYER VFI Administrator of their desire to bring a SELLER on line triggers SELLER invitations. At this point, the VFI Administrator needs to be provided the full name and e-mail address of the individual who will act as the primary contact at the SELLER’s facility who will also in turn act as the SPARS administrator for the SELLER.

From this point forward all VFI shall be transmitted electronically via the NIIIP-SPARS VES. If you have any questions regarding submittals please contact the VFI.

Coordinators: Please contact the BUYER VFI/VES Administrator at 207-442-5231 to establish your company VES Administrator.
