Hydrographic Survey

Ultra high-resolution hydrographic survey data for a range of applications. MRE is able to mobilise our own vessels or vessels of opportunity to best suit the client and their specific requirements.

Construction Support

Provision of precise surface and subsea positioning services during installation and decommissioning of marine assets. Bespoke systems are designed to aid and inform marine operations, for example in energetic high flow environments.

New Technology

Innovative application of new technologies to increase efficiency and reduce costs whilst delivering a quality product to our clients is a key feature of MRE’s survey services.


MRE operate management systems which are certified by DNV GL to ISO 9001, ISO 14001 & ISO 45001 in addition to specialised IHO hydrographic standards. Quality is at the very core of the survey services we provide.

Pipeline Condition Survey

Repeat periodic inspections of pipeline and cable routes to assess their burial status and condition form a critical part of any IRM programme; typically using high-resolution MBES and sidescan sonar systems we are able to respond quickly to both planned and emergency IRM requirements.

UXO Investigations

Providing turnkey marine UXO services to our clients from initial survey design through to acquisition and data interpretation. We also support subsequent pUXO investigations and EOD operations by divers and/or ROV with accurate subsea positioning and data management services.

Scour Monitoring

Periodic monitoring of sediment scour around WTGs and other marine infrastructure is a core activity; one which enables us to offer our clients a range of visualisation tools to evaluate multiple datasets in order to detect significant scour events.

Vessel Fleet

With MRE’s fleet of offshore support vessels, we can quickly mobilise any vessel for a wide variety of survey activities. We also make regular use of third-party vessels of opportunity where specific project requirements may dictate alternative vessel characteristics.
