Challenges in Hydrographic Surveying - a case study
Conducting accurate hydrographic surveys in Vietnam's unpredictable marine environment presents significant challenges:
- Low Visibility: Frequent poor visibility, exacerbated by rough weather and sediment disturbance, leads to inaccurate data collection.
- Severe Weather: Rapidly changing tropical conditions create risks for both crew safety and operational continuity.
- Complex Underwater Topography: Obstacles such as underwater rocks, shipwrecks, and debris complicate survey paths, affecting data accuracy.
- Equipment Limitations: The harsh marine environment demands durable and reliable surveying equipment that can withstand rigorous conditions.
These challenges resulted in operational delays and increased costs for Viet Hydrographic Survey Co., Ltd. (VHS), which serves key industries like oil and gas, marine construction, and renewable energy in Vietnam.
From Challenge to Clarity: VHS's Approach to Accurate Marine Surveys
To address these challenges, VHS turned to the Teledyne Marine SeaBat T20R-INS multibeam echosounder and that redefined their surveying capabilities.
This advanced system is designed to deliver high-resolution data, making it particularly effective for underwater hull surveys in murky waters where traditional methods often fall short.
The SeaBat T20R-INS incorporates an inertial navigation system that ensures precise positioning and stability even in the most turbulent conditions. This reliability is crucial when facing strong currents and variable sea states, allowing VHS to collect accurate data consistently.
Durability is another hallmark of the T20R. Its rugged aluminum chassis is built to withstand the rigors of the marine environment, reducing the risk of equipment failure during demanding deployments.
Furthermore, its compact design allows for easy integration with existing onboard systems, ensuring a seamless transition and fast deployment on survey vessels.
And the Results
By integrating the SeaBat T20R-INS into their operations, VHS not only enhanced their data accuracy but also improved overall operational efficiency.
This innovative solution has equipped them to overcome the persistent challenges of the marine environment while positioning them for future advancements in hydrographic surveying.
Part of the innovative
Teledyne RESON SeaBat T-Series, the T20-R sonar system is designed to serve not only the present but also the future of its customers' operational needs.
The SeaBat T20-R sonar system is compact, offering power in a small package. Yet the smaller dimension does not equate to lesser performance. The T20-R serves up accurate, reliable data when and where needed, making it an integral part of the system at work in the operational survey space. Check out the sonar solutions here.
