Sonardyne systems for Oceaneering ROVs
Sonardyne’s hybrid navigation system has been selected by Oceaneering International for its subsea Freedom and E-ROV vehicles, the company announced on 7 May.
The two vehicle systems are to be fitted with the SPRINT-Nav navigational instrument. SPRINT-Nav combines a SPRINT INS sensor, Syrinx 600 kHz Doppler Velocity Log and a high accuracy intelligent pressure sensor in a single unit.
Oceaneering’s next-generation resident hybrid ROV Freedom will debut in offshore trials later in 2019. The vehicle will be based out of docking stations on the seabed, enabling it to recharge and download data before and after its subsea inspection, maintenance and repair missions. It will operate in tethered and autonomous tetherless modes, performing both AUV and ROV related tasks, including survey, inspection, torque tool operation and manipulator-relator activities.
Char Franey, sales manager for survey and construction at Sonardyne in Houston, said: ‘Tight integration of the separate sensors within SPRINT-Nav as well as the use of high-specification ring laser gyros are behind the high performance our customers are seeing from these units. Combined with their compact form factor, these results are seeing SPRINT-Nav fast becoming the INS instrument of choice for resident vehicles.’
