The detection and clearance of ordnance in an underwater environment is a difficult and challenging operation which requires suitably qualified and experienced staff with the appropriate tried and proven equipment.
Risk assessments are carried out prior to any task to establish the nature and quantity of the potential explosive ordnance hazard that may be present in the survey area to identify and implement the appropriate risk mitigation measures.
BACTEC employs a variety of technologies for marine underwater surveys utilising specialist vessels, hardware and software including:
- Bespoke low magnetic signature survey platforms
- Deep water multi-sensor non-intrusive survey frame (up to 40m deep)
- Non-intrusive Magnetometry
- Pulse Induction Instrumentation
- Side Scan Sonar
- Sub-bottom Profiling
- Intrusive Magnetometry
- Geo referencing system (DGPS)
Navigation is critical in the survey and in the repositioning of the targets on the river or sea bed; the most appropriate positioning systems will be used. These include Differential Global Positioning Systems (DGPS), fixed land station laser sighting systems, acoustic underwater positioning systems to provide the highest accuracy of positioning possible.
The data from the survey is examined and interpreted by BACTEC's in house geophysicists to identify targets which should be investigated or avoided.
