Survey

Collecting sufficient data is vital. From the bathymetry survey of the channel, unexploded ordnance risk assessment, sediment movement and sampling to underwater archaeology and cultural heritage, survey data can help your planning construction and maintenance accurately.

The use of multi-beam and side-scan sonar surveys to detect cable exposure and measure depth of sediment cover over cable by comparison of seabed with previous surveys. Use of high resolution MBES digital terrain models, with highly accurate vertical correction for tides to monitor cable depth of cover without the use of ROVs. Acquisition speeds of 3-4 knots.

To support the pre-requisite of insurance risk assessment and authority license acquisition, we deliver unexploded ordnance survey in offshore wind farm to identify potential obstructions.

Inherited from one of the parent companies, IOVTEC, we provide integrated service package including survey techniques, Taiwan-flagged survey vessels, local experienced surveyors and state-of-the-art survey equipments. Through our track records across Europe and Taiwan, we enhance your knowledge and understanding of the geotechnical and geophysical risks associated to your projects.
