First deliveries of the CDL TOGS-NAV have been received by SMD at their state of the art facility in Wallsend, England. The first 2 systems were delivered in October on an accelerated schedule as part of a major contract awarded to CDL earlier this year.
SMD, one of the world's leading ROV manufacturers, specified the TOGS/NAV system as a standard fit to each of 20 QX-Ultra work class ROVs to be delivered to Subsea 7 / i-Tech in the next 18 months (with an option for a further 10 systems). All of the ROV's will be utilized in Brazil for upcoming work with Petrobras. The award is CDL's single largest order to date for the relatively new system which was launched early in 2010 and provides further evidence of CDL's position as a major force in the supply of navigation and inertial solutions to the Oil and Gas sector.
The unit itself is a leap forward in the provision of an integrated navigation solution for ROV systems, providing Heading, Pitch and Roll, Depth and DVL data in a single compact housing. At the heart of the unit is CDL's already successful TOGS (Tiny Optical Gyro System) - this is combined with Valeport's miniIPS (0.01% accuracy) depth sensor and RDI's industry standard Workhorse Navigator DVL to complete a powerful tool for subsea navigation.
Besides this standard functionality, by 1st quarter next year the systems have the option of upgrading (via simple firmware flash) to full INS (Inertial Navigation System) capability with DVL, depth and acoustic aiding. This will allow another level of functionality including acoustically aided mid-water station keeping - shaping up to be the next ‘must have' in work class ROV capability.
Subsea 7 / i-Tech and SMD were quick to see the benefits the TOGS/NAV system could offer and input from those companies influenced the final design and operability of the system. CDL design engineers were keen to implement their suggestions which included developing a bespoke communications protocol allowing full control and functionality for each part of the system and all data transfer over a single twisted pair.
Commenting on the award, Kevin McBarron, MD at CDL said: "The decision by both Subsea 7 and SMD to commit to the TOGS-NAV system for this contract is welcome justification for the effort and inward investment CDL have made in recent years in developing the next generation of navigation systems for the subsea oil and gas industry. Both Subsea 7 and SMD have been at the leading edge of this sector for a number of years now and we are proud to have been seen as the provider of choice. The timing of this contract coincided with the opening of our office in Rio de Janeiro and was an important factor for both SMD and Subsea 7. Our commitment to the region continues with full support and calibration facilities available for our clients from this month."
Mark Collins, Business Stream Manager - ROV Systems for SMD added: "We were impressed not only by the capability of the system but also the extra functionality that the future upgrades can provide. As a company CDL were easy to work with and showed great flexibility in meeting some specific client requests we wanted in the final product."
