President Takuzo Shimizu, Co., Ltd. President Shunsuke Toya, along with his team, has successfully developed the “Penta-Ocean Vanguard-Drone Aqua” (POV-DA), a cutting-edge oceanographic survey drone capable of vertical takeoff, landing, and cruising on the ocean’s surface.
The POV-DA boasts streamlined water operations through its advanced integration of a high-precision Global Navigation Satellite System (GNSS), thrusters, and a robust depth-measuring sonar. The Penta Ocean-licensed drone enables real-time tracking of its position, providing X, Y, Z coordinates and concurrent underwater depth readings to remote operators via a dedicated control center. The drone expertly navigates to specific monitoring points using its thrusters, maintaining a steady position despite the turbulence caused by waves and swells. These innovative features enable environmentally friendly and automated bathymetric surveys and wave observations.
Bathymetric Surveys
Traditional methods for determining depths in construction projects involving breakwaters, quay partitions, and associated structures typically relied on the use of dedicated vessels or lead-line soundings. The introduction of Point-of-View Digital Acquisition (POV-DA) technology has significantly reduced the timeframe needed to complete depth surveys, leading to increased efficiency and productivity in this process. Real-time monitoring enables operators to track underwater construction activity and identify potential requirements for additional soil deposits promptly. The group’s testing has validated that the POV-DA’s depth surveying capabilities boast an accuracy of within +/- 10 cm of conventional methods, thereby rendering it suitable for practical and reliable building management.
Wave Commentary
Marine construction and security management rely heavily on timely access to reliable climate and marine forecast data, as well as accurate wave height measurements proximal to the project site. Conducted from the shoreline, visual assessments are undertaken to assess the viability of the project. By leveraging GPS technology, the POV-DA provides instantaneous insights into wave height and timing data, empowering facility managers to assess site conditions with unprecedented speed and accuracy. The drone’s measurements demonstrate a high degree of accuracy, deviating from traditional wave meters by no more than +/- 10%, solidifying its credibility for construction applications.
With a focus on enhancing building management efficiency and feasibility evaluations, the Portable Off-vehicle Data Acquisition (POV-DA) system also captures aerial images to provide critical assistance during disaster responses, delivering real-time assessments of land and underwater damage.
The Point-of-Ventilation-Dissolved-Air system’s future developments may incorporate additional features akin to multiparameter water quality probes and water sampling devices, thereby expanding its applications to encompass coastal atmosphere conservation and comprehensive marine monitoring in construction projects.
