To meet Taiwan's deep-sea exploration and underwater engineering needs, the Marine Center has built a remote controlled unmanned aerial vehicle (ROV) capable of operating at 3,000 meters deep sea and has developed a maintenance team with autonomous operation technology to provide a reliable deep-sea research platform. This work-based ROV is capable of not only deep sea observation but also sampling for a wide range of applications, including marine energy exploration, submarine cable inspection, installation maintenance of scientific equipment, and accident search.
The center uses the Triton XLX 56 ROV manufactured by Forum Subsea Technologies in the United Kingdom and has installed a variety of scientific detection instruments specifically for marine research needs. Equipped with two sets of hydraulic robots that can carry loads of up to 250 kg, this ROV is a true deep-sea working device. The overall system consists of the ROV body, the Control Room, and the dedicated Launch and Recovery System (LARS). Below is a simple introduction to the system.
First, the ROV body can dive 3,000 meters underwater and is equipped with a variety of deep-sea detection equipment. Among them, the ROV has a 150 horsepower hydraulic system to drive 8 sets of hydraulic thrusters (4 sets of horizontal thrusters and 4 sets of vertical thrusters) and two sets of robotic arms. These robots include the Schilling Titan 4 (454 kg) and the Kraft Predator with power feedback, providing great flexibility and stability for deep-sea operations.
In addition, the ROV is equipped with 11 sets of underwater cameras and 1 camera, and is equipped with 3 sets of HD cameras for instant HD image return. To aid deep-sea photography, 4 sets of 400 watt halogen lights are installed at the front of the ROV, which are able to reproduce true colors in dim seas. When visibility is poor, the ROV uses Scanning Sonar to help the driver avoid obstacles.
The ROV is equipped with the Ultra-Short Baseline (USBL) and Deep Sea Marker Sonar (Homer), which can pinpoint the position between the ROV and the mothership and the distance between the ROV and the underwater target. Moreover, the ROV's Inertial Navigation System (INS) and Doppler Velocity Log (DVL) assist ROVs in precise carpet-like searches to meet the diverse needs of deep-sea exploration.
