Survey & Positioning

Survey & Positioning

Formerly known as iSurvey
Our goal is to minimise the environmental impact of offshore operations, our objective is to deliver safe, effective and reliable high-quality survey services.

Essential to this endeavour is to recruit and develop world-leading offshore survey and project management personnel.

The use of Unmanned Surface Vehicles (USVs) to acquire high quality data is a further step to effectively reduce the environmental impact of our services.

The complete survey service includes the iSURVEY modular tecnology suite, which has proven itself to be reliable and efficient in offshore operations worldwide, over many years.
