UNSPSC 81103001: Under water inspection in lieu of dry-docking service

In water survey (IWS) is a service required to ensure the structural and operational integrity of a marine asset

UNSPSC 81103001 Under water inspection in lieu of dry-docking service is a Commodity code covering marine vessel inspection and maintenance services performed when vessels are hauled out or in port, rather than requiring full dry-docking. State and local governments buying under this code are seeking comprehensive marine mechanic and shipyard services including hull inspection, structural assessment, propulsion system diagnostics, corrosion evaluation, and routine preventive maintenance for patrol boats, research vessels, and municipal watercraft. The issuing bodies soliciting under the code span university systems, county sheriffs' offices, and county parks departments—principally maritime asset owners operating small-to-medium patrol and research vessels that require regular scheduled maintenance and emergency repair capability.

Recent activity centers in Georgia and California. The University System of Georgia Board of Regents posted an RFQ (51800ERFQ0020472027) on October 2, 2026 for haul-out maintenance and repair of the R/V Savannah with bids due November 11, 2026, requiring a mandatory site visit on October 26 in Savannah, Georgia. Ventura County, California issued RFP 6229 in May 2026 seeking comprehensive maintenance services for Sheriff's Boat 1, a patrol vessel equipped with three Mercury 300 horsepower outboard motors, with proposals due June 16, 2026 and work commencing in July; the County's scope included scheduled 100-hour and 300-hour deep services, hull bottom painting every two years, and emergency repair capability, and required fixed pricing for scheduled maintenance with hourly labor rates for standard and Mercury-certified diagnostic work. A Texas entity posted an ITB for a pool of vendors in shipyard services in July 2026, though the posting lacked sufficient detail to characterize scope. Geographic activity appears concentrated in the Southeast and West Coast; opportunities align with summer maintenance windows and annual service cycles.
