ATRP series v4 paves the way for unmanned aquatic inspections

ATRP v4.0 Blog Update

 

A lot has happened since our last update on the ATRP. V3+ has now been retired after extensive application testing and paved the way for the v4+.

This new version takes the very best features from v3+, including the concept of “above water line propulsion”. This approach allows for an extremely shallow draft, almost zero chances of entanglement and leaves the environment below waterline untouched.

Features of the v4 include-

·         A greater payload capability, both in weight and fittings. Using a more commercially available fitting system opens the possibilities for more off the shelf technologies to be utilised.

·         We’ve now implemented the use of a partially flooded bow section for easier navigation of submerged/surface items.

·         External IP64 rated power sockets meeting the wider requirements of additional equipment.

·         Full-length high-power LED lights on both sides of the vessel, to illuminate even the darkest of environments and to improve situational awareness.

·         2x UHF telemetry downlinks across two frequency bands for range and redundancy. The control network utilises military grade encryption to ensure the highest levels of security.

·         1x SHF video downlink to provide situational awareness for manual operations. The video downlink also provides an on-screen display with a wealth of information to aid the operator in navigating complex environments.

·         LiDAR capability, both for obstacle/collision avoidance when used in autonomous modes, and for survey use. The information from the LiDAR unit is stored locally as well as being fed back to the operator.

·         Improved battery life with the use of lithium iron technology.

·         Full waypoint mission capable, along side the option of manual operations.

V4+ has seen many hours on British waterways and has proven itself time and time again not only on open water survey work, but also in highly complex environments with little to no light, and no access for the operator. There is a v5+ in the works designed with a slightly different task in mind and is set to see water trials over the winter period.

Using an autonomous boat for bathymetric surveys offers several benefits over manned boats. Here are some key advantages:

  1. Cost-Effectiveness: Autonomous boats can potentially reduce costs associated with conducting bathymetric surveys. They eliminate the need for hiring and maintaining a crew, thereby reducing labor expenses. Additionally, autonomous boats can operate for extended periods, allowing for more efficient data collection without the need for frequent crew shifts or rest breaks.

  2. Improved Safety: Bathymetric surveys often involve working in challenging or hazardous environments, such as rough waters or areas with submerged obstacles. By utilizing autonomous boats, the risk to human operators is eliminated. This enhances safety and mitigates potential accidents or injuries that could occur during surveys.

  3. Increased Efficiency: Autonomous boats can operate continuously without human fatigue, enabling longer survey durations. They can work around the clock, collecting data at a consistent pace without breaks. This increased efficiency translates into faster completion of surveys and quicker availability of data for analysis.

  4. Consistency and Accuracy: Autonomous boats follow programmed routes with precision, ensuring consistent coverage of the survey area. They can maintain a constant speed and maintain a consistent distance from the seafloor, resulting in more accurate and reliable bathymetric data. The absence of human error, fatigue, or variations in surveying techniques further enhances the quality and reliability of the collected data.

  5. Flexibility and Adaptability: Autonomous boats can be easily programmed to navigate complex routes or survey areas that may be challenging for manned boats. They can adjust their course and speed as needed, making them highly adaptable to changing conditions or specific survey requirements. This flexibility allows for efficient data collection in various marine environments.

  6. Remote Operation and Monitoring: Autonomous boats can be remotely operated and monitored from a control station onshore or on another vessel. This feature enables real-time monitoring of the survey progress and the ability to make adjustments or intervene if necessary. Remote operation also eliminates the need for surveyors to be physically present on the boat, reducing logistical challenges and increasing accessibility to remote or offshore survey areas.

Overall, the use of autonomous boats for bathymetric surveys offers cost savings, enhanced safety, increased efficiency, improved data quality, and greater flexibility compared to traditional manned boats. These benefits make autonomous boats an attractive option for conducting bathymetric surveys in a wide range of marine environments.
