About the company
Portus Stevedoring LLC, a Jacksonville, Florida-based limited liability company, provides stevedoring and marine cargo handling services to the Department of Defense as a prime contractor operating under full-and-open competition with no set-aside designations. The vendor operates exclusively as a prime (100% of recent awards) and does not subcontract; its federal footprint is concentrated in military maritime logistics with 130 of 133 recent awards classified under NAICS 441228 (Marine Cargo Handling) and 131 awards under PSC code Transportation/Travel/Relocation—Stevedoring.
Customer concentration is acute. The Department of the Army Materiel Command Surface Deployment and Distribution Command (SDDC) dominates the portfolio with 107 awards accounting for $82.6 million of the $126.2 million combined potential value—a 65% share by dollars. The United States Marine Corps ranks second with 17 awards and $43.3 million combined potential value, followed by the Department of the Navy Naval Facilities Engineering Command (5 awards, $275 thousand), Department of the Army (2 awards, $24 thousand), and the Naval Supply Systems Command (1 award). The two rankings align tightly; SDDC is both the largest customer by volume and by dollars.
Portus Stevedoring holds positions on five primary vehicle IDCs. The top two by task-order count are HTC71115DR030 (51 task orders, $1.9 million combined potential value) and HTC71115DR033 (39 task orders, $6.9 million combined potential value)—both appear to be Army SDDC stevedoring vehicles. Additionally, the vendor holds Marine Corps IDC M6700416D0001 (8 task orders, $7 million combined potential value) awarded June 2025 and running through June 2030, and M6700421D0001 (7 task orders, $4.7 million combined potential value). A sixth vehicle, Army IDC W81GYE10D0010, carries 6 task orders and $20.5 million combined potential value. Recent Marine Corps work includes delivery orders for stevedoring and related terminal services in Jacksonville awarded June 2026 ($1.55 million ceiling), July 2025 ($1.51 million ceiling), June 2024 ($1.52 million ceiling), and April 2023 ($821 thousand ceiling), all firm fixed-price and supporting the Marine Corps Maritime Prepositioning Force program.
Activity has been sparse but consistent. The vendor received 133 total awards since 2002, with two awards in 2025, one in 2024, one in 2023, and three in 2022; the most recent award arrived June 2026. Only one award reaches ultimate completion within the next twenty-four months (combined potential value $1.6 million), leaving the bulk of the portfolio insulated from near-term recompete pressure. Obligated dollars stand at $57 million against $126.2 million in combined potential value—a 45% obligation rate typical of longer-duration IDC work with uneven task-order velocity.
