About the company
Clarkson Research Services LIMITED, doing business as Clarksons, operates as a foreign-owned for-profit organization headquartered in London, United Kingdom, that sells maritime industry intelligence and data subscriptions to federal agencies as a prime contractor. All forty of Clarksons' federal awards are direct prime contracts; the vendor does not subcontract to other primes and has no federal subcontract footprint. Clarksons competes in full-and-open procurements with no set-aside designations across all awards.
The vendor's core capability centers on subscription-based maritime intelligence platforms: the Shipping Intelligence Network (SIN), World Fleet Register (WFR), Offshore Monthly Monitor, and Renewables Intelligence Network (RIN). These databases serve as data and analysis resources for maritime policy analysis, trade intelligence, shipping industry monitoring, and vessel registration tracking. Representative prime awards include a $398,180 five-year firm-fixed-price purchase order from the U.S. Army Corps of Engineers (awarded July 2025) for commercial world fleet vessel register data covering active, inactive, newbuild, and permanently withdrawn commercial vessels 70 DWT/100 GRT and larger with monthly updates, supporting the USACE Waterborne Navigation Program and Institute for Water Resources; a $45,100 purchase order from the Maritime Administration (August 2026) for annual subscriptions to SIN, Offshore Monthly Monitor, and RIN running through July 2027; and a $12,600 purchase order from the International Trade Administration (September 2026) for World Fleet Register Platform subscription running through September 2027.
Customer concentration is heavily skewed toward maritime agencies. The Department of the Navy Office of Naval Intelligence accounts for 99% of combined potential value across its nine awards ($3.9 million), though the Department of Transportation Maritime Administration drives award volume with twenty-one awards carrying $406 thousand combined potential value. The top five customer agencies represent 90% of award count. This divergence reflects Navy's anchor of three large IDIQs (Indefinite Delivery Contracts N6817113D0005 and N6817116D0011, each with three task orders totaling $891 thousand and $892 thousand respectively) alongside Maritime Administration's recurring subscription renewals. Department of Homeland Security U.S. Coast Guard, the U.S. Army Corps of Engineers, and the Office of the U.S. Trade Representative complete the active customer roster.
Activity has remained flat to modest over the past five years — two to three awards annually from 2022 through 2025, with two awards in 2026 — generating $2.6 million in combined dollars obligated against $4.8 million in combined potential value. Only two awards (combined potential value $58 thousand) reach ultimate completion within the next twenty-four months, presenting minimal near-term recompete exposure. Awards fall primarily under NAICS Internet Publishing and Broadcasting and Web Search Portals (fourteen awards) and All Other Information Services (eight awards), with PSC coding concentrated on IT and Telecom Web-Based Subscription (thirteen awards) and Special Studies/Analysis–Data (seven awards).
