What Rivertrace Limited does

Rivertrace Limited is a UK-based private company founded in 1983 that designs, manufactures and services oil-in-water monitoring and control devices for marine, offshore and industrial customers. Its product platform centers on the SMART series (SMART ODME for tanker slop water and ballast, SMART BILGE+ for 15 ppm bilge alarms, SMART PFM 107 for produced water, SMART CONNECT and SMART HUB for centralized digital monitoring, SMARTSAFE ORB for discharge interlock, SMART ESM for scrubber washwater, SMART WiO, SMART 40M, SMART 50M and SMART TURBIDITY) together with the OCD Xtra and OCD CW analyzers. The underlying technology is a proprietary photo-optical measuring cell combined with optical microscopy to differentiate oil particles, gas bubbles and solids, a capability the company considers critical for reliable measurement in produced water streams where conventional 15 ppm sensors misread. Type approval to IMO resolutions MEPC.107(49), MEPC.108(49) and MEPC.240(65) is the principal commercial anchor and is what makes the equipment deployable on regulated commercial tonnage worldwide.

The company monetizes through one-time sales of monitoring equipment, a recurring service and maintenance stream, and genuine spare parts, augmented by application-engineering and consultancy engagements with EPC, EPCI and FPSO contractor teams from concept and FEED through commissioning and first oil. Pricing is quote-based on multi-year contracts; the company does not publish list pricing. Go-to-market is consultative direct sales supported by a network of channel partners and service agents globally, with exclusive regional representation in Thailand, Philippines and Hong Kong distributing complementary ultrasonic products from Portal Instruments. Primary customers are enterprise buyers: tanker operators (crude, product and chemical), general vessel operators needing bilge alarms, FPSO operators and offshore production facilities with produced water discharge permits, EPC contractors specifying topsides monitoring, and industrial sites with scrubber, boiler or process water needs. Rivertrace is privately held with no disclosed external shareholders or funding rounds; Martin Saunders serves as Managing Director. The company is ISO 9001:2015 certified, holds Cyber Essentials 2024, and operates within ATEX 2014/34/EU, Marine Directive 2014/90/EU and IECEx frameworks.
