SeaPort-NxG Task Orders Have Moved to PIEE: The 2026 SeaPort Portal Transition Guide
For two decades, Navy services contractors had one answer to "where do SeaPort task orders come out?" That answer is now wrong. As of January 1, 2026, no new SeaPort-NxG task order solicitations are posted in the SeaPort Portal, and on June 30, 2026 the portal itself began decommissioning. Task order solicitations for the Navy's flagship services vehicle now flow through the PIEE Solicitation Module, with contract writing moving to the Navy's Electronic Procurement System (ePS). If your BD team is still checking the old portal, you are watching an empty room.
TL;DR
- SeaPort-NxG task order solicitations moved to PIEE. Since January 1, 2026, all Navy SYSCOMs release new SeaPort task order solicitations through the PIEE Solicitation Module (PIEE SOL), not the SeaPort Portal.
- The SeaPort Portal is being shut down. It was locked for edits on April 1, 2026 and began decommissioning on June 30, 2026, after which vendors lost the ability to download their historical data.
- Awards and modifications now run through Navy ePS. The government writes and manages SeaPort contract actions in its Electronic Procurement System, while industry-facing solicitation distribution and offer submission happen in PIEE SOL.
- This is bigger than SeaPort. Under updated DFARS procedures, contracting officers across the Department of Defense are directed to use the PIEE Solicitation Module for publishing unclassified solicitations and receiving offers effective October 1, 2026, with limited exceptions. SeaPort is the early, high-volume test case.
- You need PIEE roles now, not at proposal time. Viewing controlled solicitations and submitting offers requires an active PIEE account with the right roles (including Proposal Manager to submit). Account setup and role approval take time you do not want to spend inside a 14-day response window.
- CLEATUS tracks Navy task orders through the platform change. The SeaPort NxG integration and Auto Capture keep Navy opportunities flowing into one AI-managed pipeline, and a direct PIEE integration is coming in early August 2026, so a government system migration doesn't become a gap in your capture coverage.
Never Miss a Navy Task Order Again
CLEATUS monitors Navy opportunities continuously and delivers matched task orders with AI analysis, so portal migrations never blind your pipeline.

What SeaPort-NxG Is, and Why This Transition Matters
SeaPort Next Generation (SeaPort-NxG) is the Navy's mandatory-use multiple-award IDIQ for engineering and program management support services. NAVSEA, NAVAIR, NAVWAR, NAVFAC, NAVSUP, the Office of Naval Research, Military Sealift Command, and the Marine Corps all compete services requirements through it. Thousands of companies hold prime positions on the vehicle, including more than 1,000 new primes admitted in the January 2025 Rolling Admissions II awards, and a large share of them are small businesses whose entire Navy pipeline runs through SeaPort task orders.
For those companies, the SeaPort Portal was not just a website. It was the opportunity feed, the Q&A channel, the amendment tracker, and the proposal submission system rolled into one. Every capture process, every BD checklist, and every "check the portal" calendar reminder pointed at it.
That is what makes this transition consequential. The Navy did not redesign the portal. It removed the portal from the opportunity path entirely and split its functions across two enterprise systems:
PIEE Solicitation Module (PIEE SOL) is now the industry-facing side. Contracting officers post SeaPort task order solicitations, amendments, and attachments there, and vendors submit questions and offers through it. PIEE, the Procurement Integrated Enterprise Environment at piee.eb.mil, is the same DoD platform contractors already use for invoicing through Wide Area WorkFlow, so most primes have an account. Far fewer have the solicitation-side roles set up.
Navy ePS is the government-facing side. The Electronic Procurement System is where contracting officers now write, award, and modify SeaPort task orders. Vendors do not work inside ePS, but its rollout schedule drove the migration timeline, and award documents now originate there rather than in the SeaPort Portal.
The Full Transition Timeline
The Navy phased the migration by command, then locked and decommissioned the legacy portal. Here is how it played out:
| Date | What Happened |
|---|---|
| November 17, 2025 | ONR and the Naval Research Laboratory began migrating SeaPort actions to ePS and PIEE SOL |
| December 1, 2025 | Additional Navy commands migrated; some ordering offices began releasing solicitations via PIEE SOL early |
| January 1, 2026 | All SYSCOMs, including NAVSEA, began migration. No new solicitations posted in the SeaPort Portal for anyone from this date forward |
| February 28, 2026 | All SYSCOM SeaPort task order transactions fully transitioned to the new systems |
| April 1, 2026 | SeaPort Portal locked for edits. No task order awards, modifications, or solicitations processed in the legacy system |
| June 30, 2026 | SeaPort Portal began decommissioning. Vendor access to download historical information ended |
| October 1, 2026 | DoD-wide: contracting officers directed to use the PIEE Solicitation Module for publishing unclassified solicitations and receiving offers, with limited exceptions |
Dates were subject to adjustment against the Navy's broader ePS implementation goals, and individual ordering offices communicated specifics through portal notices and direct vendor outreach during the transition. If a task order you are tracking seems to have gone quiet, the first question to ask is no longer "did we miss an email" but "which system is it living in now."
What Changed for Vendors, In Practice
Your opportunity feed moved. New SeaPort task order solicitations, amendments, and Q&A now appear in PIEE SOL. The old rhythm of logging into the SeaPort Portal and scanning your zones and functional areas no longer surfaces anything new. Teams that have not rebuilt their monitoring around the new system are structurally late to every competition.
Access is role-based and takes setup time. A basic PIEE account is not enough. To view solicitations with controlled attachments and to submit offers, your team needs the solicitation-side vendor roles, and the Proposal Manager role is required to actually submit an offer. Roles are tied to your CAGE code and require approval workflows. Doing this for the first time inside a live response window is how proposals miss deadlines for reasons that have nothing to do with the technical volume.
Submission mechanics are different. SeaPort proposals used to go through the portal's submission flow that Navy contractors knew by muscle memory. PIEE SOL has its own offer submission process, file structure expectations, and confirmation flow. It is not difficult, but it is different, and "different" is risk when a deadline is hours away.
Your historical record went dark. The June 30, 2026 cutoff was hard: after decommissioning began, vendors lost access to download past proposals, task order documents, and correspondence from the SeaPort Portal. If your team did not export its history in time, your institutional record of past SeaPort competitions now lives only in whatever your team saved locally. For anything mission-critical that slipped through, your SeaPort contracting representatives are the remaining path.
Award visibility shifted. With contract writing in ePS, award and modification documents originate in a different system with different notification behavior. Incumbent watchers and competitive intelligence processes keyed to the old portal's award postings need to be rebuilt against the new data flow.
"The PIEE Solicitation Module currently posts SeaPort task orders under restricted visibility to contract holders, not on public SAM.gov. If you are a subcontractor building pipeline around SeaPort work, your prime relationships are now your only line of sight. Make sure your primes know what you want to see."
This Is Not Just a SeaPort Story
The SeaPort migration is the most visible piece of a much larger consolidation. Updated DFARS procedures direct contracting officers across the Department of Defense to use the PIEE Solicitation Module for publishing unclassified solicitations and for receiving offers and quotes effective October 1, 2026, with exceptions for cases like sole-source actions, simplified acquisitions, emergency acquisitions, and awards made outside the United States.
In other words, the skill your team just had to learn for SeaPort is about to become the default mechanic for a large share of DoD competitions. Companies that get their PIEE house in order now are not just fixing their Navy pipeline. They are getting ahead of a department-wide shift in how solicitations are distributed and how proposals are received.
This follows the same pattern we covered when FPDS was retired into SAM.gov: the government is consolidating a sprawl of legacy procurement systems into a handful of enterprise platforms. That consolidation is rational for the government. For contractors, every migration is a window where opportunities get missed, historical data gets stranded, and teams lose time relearning mechanics instead of winning work.
What Navy Contractors Should Do Right Now
1. Get PIEE Access and Roles Squared Away
If anyone on your capture or proposal team lacks an active PIEE account, fix that this week. Register at piee.eb.mil against your CAGE code, request the Solicitation Module vendor roles, and make sure at least two people hold the Proposal Manager role so a single vacation does not block an offer submission. Verify your SAM.gov registration is current, since your PIEE access hangs off your entity record.
2. Rebuild Your Monitoring Around the New Systems
Delete the "check SeaPort Portal" step from your BD process and replace it with coverage of PIEE SOL for your zones and functional areas. Confirm your notification settings inside PIEE actually reach the right inboxes. If you rely on primes for subcontracting visibility, re-establish expectations with them now, because their notification behavior changed too.
3. Reconstruct Your SeaPort History
The download window closed on June 30, 2026. Inventory what your team saved locally: past proposals, task order documents, Q&A records, award notices. Centralize whatever exists into a single document repository so your past performance and competitive history survive the portal that originally held them. For gaps that matter to an active pursuit, contact the cognizant contracting office.
4. Run a Dry-Run Submission Before You Need One
Do not let your first PIEE SOL offer submission be a live one. Walk the submission flow on a low-stakes response or a practice basis, document the steps, and time it. The goal is that on proposal day, the mechanics are boring.
5. Stop Letting Portal Changes Define Your Pipeline
This is the durable lesson. SeaPort moved. FPDS moved. DIBBS, eBuy, and dozens of state and local systems each have their own quirks and their own migration histories. If your opportunity discovery depends on humans remembering which portal to check, every government system change is a threat to your revenue. The fix is not more checklists. It is moving discovery to a platform that watches all of the sources continuously and treats a portal migration as a plumbing change, not a pipeline outage.
Why Watching PIEE Alone Isn't Enough
Even with perfect PIEE hygiene, the module gives you listings, not intelligence. It will show you a task order solicitation. It will not tell you which of your past contracts make you competitive for it, who the incumbent is, what the agency has historically paid for this scope, or whether the response timeline is realistic for your team. It covers SeaPort and a growing share of DoD solicitations, but none of your federal-civilian, state, or local pipeline.
That analysis gap is where competitions are actually won. A task order with a 14-day response window rewards the team that starts with a compliance breakdown and a draft outline on day one, not the team that spends the first week rebuilding context that intelligence tooling should have delivered with the opportunity.
How CLEATUS Keeps Your Navy Pipeline Intact
CLEATUS was built so that government system migrations are our problem, not yours.
Navy task orders flow into one pipeline. The SeaPort NxG integration brings your SeaPort task orders into CLEATUS alongside everything Auto Capture finds across 40,000+ federal, state, and local sources. AI matches each opportunity against your capture profile, past performance, and strengths, so your team starts the day with a prioritized queue instead of a portal checklist.
A direct PIEE integration is coming in early August 2026. CLEATUS is extending the same connect-once model to PIEE itself: link your PIEE access and the task order solicitations, amendments, and Q&A distributed through the Solicitation Module flow straight into your pipeline, already matched and analyzed. As the October 2026 DoD-wide mandate pushes more solicitations into PIEE SOL, that coverage extends well beyond SeaPort.
Every task order arrives analyzed. GovCon Copilot reads the full solicitation package, the base solicitation, attachments, and amendments, and produces the fit assessment, compliance picture, and key dates before your team invests an hour. When an amendment lands, the analysis updates instead of hiding in a notification nobody opened.
Short response windows stop being disqualifying. The AI Proposal Suite builds compliance matrices, win themes, outlines, and structured draft volumes grounded in your actual past performance. For task order competitions where the response clock is the biggest competitor, that is the difference between bidding and watching.
"CLEATUS transformed our entire operation. We tripled our output with the same team and eliminated days of manual work."
– John Garnish, Business Development Lead, D2 Government Solutions
MST Maritime Management, a maritime services firm working in exactly the Navy-adjacent market SeaPort serves, went from 3 proposals a month to more than 10 with CLEATUS, with 75% faster opportunity discovery. That throughput is what a healthy task order practice looks like when discovery and analysis are automated: more shots on goal, faster, without adding headcount.
