DOF Subsea has chosen acoustic and inertial navigation technology from Sonardyne Brasil to support its deepwater operations from three vessels offshore Brazil.
The three vessels will be equipped with Sonardyne’s SPRINT-Nav all-in-one subsea navigation instrument for underwater vehicles.
A remote operated vehicle (ROV) on one of the vessels will also be fitted with a Sonardyne Syrinx Doppler Velocity Log (DVL), in place of its existing system. All three vessels are on long-term contract in Brazilian waters.
DOF Subsea’s multiple SPRINT-Nav systems will be used to support ROV operations, as part of construction, inspection, maintenance and repair (IMR) work in Brazil’s deepwater pre-salt oil fields, in depths down to 3,000 metres.
Andre Moura , sales & applications manager for Sonardyne in Brasil, said: “To meet stringent specifications for subsea inertial navigation, operators are more and more looking for high-performance instruments and our SPRINT-Nav meets their needs. SPRINT-Nav offers unmatchable performance.”
