EGS is a leading international group of companies with offices in Europe, the Americas, Asia and Australia. EGS provides global specialist multi-disciplinary marine survey support, and delivers solutions to the  Telecommunications, Renewables, Oil and Gas, Charting and Marine Infrastructure market sectors.

First established in the UK in 1974 by Nigel Ridley Thomas and John Jopling at a small office near Heathrow airport, London, the company soon expanded to Asia where offices were established in Singapore and Hong Kong in the 1970’s and 1980’s. EGS remains an independent company, which over the last 48 years has grown into an international network of services hubs and centres of excellence with 14 offices located in 12 countries around the globe.

EGS has gained a reputation for professional excellence in the geophysics and survey sectors, being well known for our ability to find imaginative solutions to problems. Being proactive, EGS make sure that the service we provide is always tailored to satisfying our client's needs. This explains why our onboard near real-time reports are being hailed as setting the benchmark in our field.

We established EGS Marine Ltd. in 2007 in the Philippines to effectively manage, crew and service our ever expanding fleet of EGS Group vessels around the globe.
