EGS offers both terrestrial and subsea laser scanning. Dimensional Control and monitoring services, utilizing proven engineering survey techniques and modern survey equipment, can provide substantial benefits to any project both onshore and offshore.
Dimensional control applications:
Long baseline (LBL) positioning has many applications both commercially and in research, from surveying a ship hull to positioning offshore platforms in deeper waters. The technique consistently provides accuracies in the order of decimetres over large areas, independent of depth. Recent advances include the integration with other acoustic techniques or with inertial navigation systems for greater levels of accuracy.
EGS provides the following LBL metrology services:
In addition to high accuracy surface vessel positioning, EGS owns a range of acoustic tracking and measurement equipment, that can be seamlessly integrated into the barge or installation vessel’s survey systems.
Combined together, Ultra Short Baseline (USBL) and Long Baseline (LBL) equipment provide a high accuracy solution for subsea positioning including ROV operations, diver-less metrology and spool piece design. For high accuracy positioning of ROV in deepwater environments, Inertial Navigation Systems (INS) can be integrated with LBL and other sensors to provide a solution to ensure the client’s specifications are achieved.

The co-operation and working relationship between all parties during all phases of this project has been a text book example of how to conduct survey operations etc.Holland, Geoff
I just wanted to take the opportunity presented by the end of survey data acquisition activities to say thank you and well done on the excellent performance of the EGS team through the execution of the works to date. Whilst I’m mindful that there is still much to do in terms of tide gauge recovery, data processing and deliverable preparation – the performance of all personnel involved to date from EGS and Broadsword has been exemplary and particularly, the professionalism and attention to detail of the site team. It’s also been particularly pleasing to see this complicated and challenging scope completed in such a competent and hassle-free manner.Rhys Jones
I would like to thank you for this excellent survey. Your team was professional and knowledgeable. It was a pleasure to work with them.Philippe Hubert
On behalf of TOTAL E&P PNG and InterOil, we would like to express our gratitude for the efficient operation of the survey as well as safe and timely return to Port Moresby. It was a pleasure working with you all on the ground. We wish you all the best in your future endeavors.Anton A Safronov
