Survey and Positioning

We are specialists in the conduct of nearshore and inland waterway geophysical surveys. Utilising a variety of techniques and technologies with both small manned and unmanned vessels equipped with GNSS positioning, Multibeam, Sidescan Sonar, Magnetometer and Sub-Bottom Profilers; data can be captured for bathymetric charting, feature and object detection and determination of the shallow seabed geology.

Our surveyors have many years’ experience of conducting hydrographic surveys for a broad range of projects and applications.

We can offer complete or partial surveys of a port; using multibeam sonar to map below the waterline including the seafloor and quay wall structures, through to laser scanning buildings, pontoons and slipways.

Our highly qualified and experienced surveyors are experts in conducting shallow water bathymetric surveys. We can capture precise hydrographic information to support the safety of navigation in compliance with the Port Marine Safety Code. 

From depth charting to locating submerged obstructions, our team have over 20 years of experience in this field.

We have built over 20 years of experience mobilising and calibrating survey vessels. Our highly experienced team are experts in physically installing survey equipment and networking the software to allow all survey systems to work as intended.

With further understanding of geodesy and positioning, our team are able to conduct navigational and gyro checks, with the ability to produce a report for the client.

We are able to further assist clients with the calibration of the survey equipment to allow for onward survey operations. 

Through our associate network of trusted and qualified survey personnel, we have extensive experience within the marine survey industry. Our experience includes development of survey specifications; survey planning and project management; data QA and reporting; MBES installation and commissioning.

We are well positioned to provide advice, guidance and ongoing consultancy in respect of all phases of survey planning and offshore operations. We are also able to provide offshore survey personnel and client representation using out trusted associate network to ensure both survey specifications and health and safety standards are being adhered to.

We provide a full Dimensional Control service to vessels of all sizes, afloat or ashore. Through this process any node can be coordinated to a defined vessel reference frame (VRF).

Our Vessel Calibration Surveys allow survey sensors to operate within their specified tolerances, which will in turn provide accuracy and confidence in subsea datasets. We provide proof through our independent verification process that the combined vessel survey system is working to desired tolerances.

We provide full Vessel Calibration and Verification Surveys including: Gyro Calibration; Vessel Motion Sensor Calibration and Verification Surveys; GNSS Position Verification and Health Checks.

GEOBASE is a software application uniquely designed to provide hydrographic surveyors with an independent resource for conducting a vessel dimensional control survey, an attitude and heading sensor calibration, and a GNSS position verification.

This allows users to create an independent database which can be used to manage and quality assure the geometry of the vessel and its installed survey sensors and their relationship to each other for the life cycle of the vessel and or the project on which the vessel is engaged.
