Offshore Site Investigation &
Advanced Geotechnical Testing
Key Services Offered
Geonamics (S) Pte Ltd is a SAC-SINGLAS accredited provider of marine geotechnical solutions for offshore and coastal infrastructure across Southeast Asia.
With decades of field experience and a fleet of 10+ purpose-built jack-up barges (operating to ~40 m water depth), we deliver nearshore, offshore and deepwater site investigations, advanced in-situ testing, and real-time data acquisition. We have strong track records of working safely and efficiently in high-traffic corridors — including Temasek Fairway, Sinki Fairway, Keppel Fairway, ALVCC, and Raffles Shoal supporting coastal reclamation, port development, submarine cable landings, and dike/foundation design.
