US Navy foresees an uncrewed future for its surface and underwater fleet
The service has been conducting various procurement and development efforts to integrate unmanned surface and underwater vehicles into its inventory.
DOF Subsea selects Sonardyne navigation technology
Sonardyne’s acoustic and inertial navigation technology has been selected by DOF Subsea to support its deepwater operations with three ROV vessels off the coast of Brazil, the company announced on 9 October.
The three vessels will be equipped with Sonardyne’s SPRINT-Nav all-in-one subsea navigation instrument for underwater vehicles. An additional ROV will also be fitted with a Sonardyne Syrinx Doppler Velocity Log, in place of its existing system.
The vessels are on long-term contract, carrying out ROV operations as part of construction, inspection, maintenance and repair work in Brazil’s deepwater pre-salt oil fields, at depths down to 3,000 metres.
SPRINT-Nav combines Sonardyne’s SPRINT sensor, Syrinx 600 kHz DVL and a high accuracy intelligent pressure sensor in a single housing, for subsea inertial navigation and positioning.
