Overview:  Seaport Next Generation (NxG) is a multiple-award, indefinite delivery, indefinite quantity (IDIQ) contract vehicle. Task orders issued on this contract vehicle will support Naval Sea Systems Command, Space and Naval Warfare Systems Command, Naval Supply Systems Command, Military Sealift Command, Naval Facilities Command, the Office of Naval Research, and the U.S. Marine Corps.

“SeaPort” is the electronic procurement tool by which all Navy and Marine Corps contracting offices can obtain services through competitive and efficient means. Task Order requirements are developed, solicited, awarded and administered all within the SeaPort Portal.

“SeaPort-NxG” is both the electronic module within the SeaPort Portal as well as the set of Indefinite Delivery Indefinite Quantity (IDIQ) Multiple Award Contracts (MACs) that is available for use in conducting competitive procurements among its vendor participants.

All potential SeaPort-NxG task orders shall offer a fair consideration/opportunity in accordance with FAR 16 to all SeaPort MAC holders. No sole source work, direct ordering to a vendor or exceptions to FAR 16 Fair Opportunity are allowable in SeaPort. In the event a valid basis to not offer a fair opportunity exists, an alternative (non-SeaPort-NxG) contracting method will be used.

Only Authorized Ordering Offices may place orders under SeaPort-NxG. Currently, only Navy Activities are authorized to place orders.

All contract awards have the same terms and conditions and reflect a maximum Cost Plus Fixed Fee (CPFF) and Pass Through rate of 8%.

The SeaPort-NxG contract vehicle furthers the Navy’s objective to increase efficiency and allows geographically dispersed organizations with diverse technical support requirements and missions to tailor their requirements within a specific task order.
