Small ROVs Upgraded with Advanced DVL Sensors

QYSEA FIFISH ROV

ROV manufacturer QYSEA has partnered with underwater acoustics specialist Water Linked to provide QYSEA’s Remotely Operated Vehicles (ROVs) with advanced underwater positioning sensors. The Water Linked A50 Doppler Velocity Log (DVL) will be the standard issue for QYSEA’s FIFISH V6 Expert, PRO V6 Plus and PRO W6 ROVs.

Following extensive evaluation of the A50 DVL, QYSEA placed an initial order for 10 units, and soon after increased this order to meet the growing demand for increased vehicle capability among their clients. The size, weight, and performance capabilities of the Water Linked A50 DVL made the unit an excellent choice for high-accuracy ROV navigation.

Integrating the A50 into the control system of their ROVs has allowed QYSEA to offer advanced ROV station lock and control capabilities. These features allow operators of these smaller ROVs to undertake tasks that are typically undertaken by considerably larger vehicles.

Depth rated to 300m, the A50 can be used on an extensive range of ROVs. Where there is a need to operate at greater depths, the Water Linked A125 DVL is available rated to 500m or 3000m.

Scott McLay, Chief Commercial Officer of Water Linked, commented: “This commitment by QYSEA to the Water Linked DVL, following extensive evaluation, is a great testimony to the ability of our engineers to develop high performance sensors that meet the needs of the industry, enabling small vehicles to operate in harsh environments.”

Li Ping, QYSEA’s Marketing Director, noted: “We at QYSEA have already successfully integrated the Water Linked Underwater GPS G2 system with a number of our current vehicles, providing users with additional navigation capability. The DVL integration has allowed us to further enhance the user experience, enabling QYSEA to support the needs of a growing commercial market for highly capable small vehicles.”
