Seabulk Logistics Services LLC

Seabulk Logistics Services LLC, operating as First Line Solutions, is a for-profit limited liability company that provides ship husbanding and port logistics support services to the U.S. Navy as a prime contractor, competing on a full and open basis with no set-aside designations. The vendor holds positions on three major Navy IDIQs covering global maritime logistics — the Global Husbanding Support Services contract ($1.682 billion, performance through October 2030), the Seaport Next Generation (Seaport-NXG) contract ($4.0 billion, through January 2029), and the Worldwide Expeditionary Multiple Award Contract TITUS (WEXMAC TITUS, $1.8 billion, through December 2029) — and delivers a concrete portfolio of port-call support: vessel provisions, fuel supply, waste removal, tugboat and line handling, security services, transportation, charter and hire services, and shoreside utilities and appliances.

The vendor's customer concentration is entirely within the Department of the Navy across eight named organizational buyers. Pacific Fleet Forces leads by award count with eleven delivery orders carrying $1.68 billion in combined potential value, while Naval Sea Systems Command anchors the dollar rankings with two Seaport-NXG awards totaling $4.0 billion in potential value. Atlantic Fleet Forces Command has executed eight husbanding task orders valued at $2.8 million combined, and Naval Supply Systems Command holds two WEXMAC awards worth $1.8 billion. The top five Navy customers account for 89% of recent awards. Activity is episodic: one award in 2020, then a jump to eleven in 2023, ten in 2024, five in 2025, and one to date in 2026. The vendor's combined potential value across all 28 awards stands at $7.49 billion, though only $6.9 million has been obligated across the footprint, reflecting the heavy weighting toward large IDIQs with task-order-level execution. Twenty-one of the vendor's task orders execute against the Global Husbanding Support Services vehicle, with individual delivery orders ranging from $50 thousand to $1.39 million for specific vessel port calls at U.S. and overseas locations including Key West, San Francisco, Tampa, Portland, Astoria, Long Beach, and Taiwan. The vendor operates across port husbanding (PSC Ship Husbanding Services—Management/Integration Service, 16 awards) and force protection logistics (Husbanding Services—Force Protection, 5 awards) primarily under NAICS 541330 (Facilities Support Services) and 488310 (Port and Harbor Operations). The vendor is a pure prime with no subcontractor footprint and all awards competed without set-aside protections, positioning Seabulk as a fully open-market competitor in Navy logistics.
