The first two of the CDL TOGS-NAV systems were delivered to SMD at their facility in Wallsend, England, in October on an accelerated schedule, as part of a major contract awarded to CDL, earlier this year.
SMD, an ROV (remotely operated vehicle) manufacturer, said that the system suited each of the 20 QX- work class ROVs to be delivered to Subsea 7/i-Tech over the next 18 months. This is the company’s single largest order to date for the system launched in early 2010.
The unit provides an integrated navigation solution for ROV systems with heading, pitch and roll, depth and DVL data in a single compact housing. At its centre is the TOGS (Tiny Optical Gyro System) combined with Valeport's miniIPS (0.01% accuracy) depth sensor and RDI's Workhorse Navigator DVL to complete a tool for sub-sea navigation.
