CDL MobIUS heads to Angola for Subsea 7Subsea 7 and Seatronics are the first companies to commit to the MobIUS (Mobile Inertial Underwater System) which has launched at this year's Oceanology by Subsea Engineering Company CDL. Demonstrating CDL's commitment as a customer focused solutions provider the MobIUS is their latest subsea development, providing Heading, Attitude, Depth, Speed of Sound, Acoustic Telemetry and Ranging in a slim, compact, rugged ROV friendly package.



The system is extremely flexible and is available with CDL Datum (Digital Acoustic Transponder & Underwater Modem) or with adaptor plate to suit the acoustic ranging and telemetry transponder of your choice, providing the ideal solution for a variety of tasks ranging from shallow water installations to deepwater metrology. Seatronics were quick to see the benefits of this integrated solution and were instrumental in demonstrating to Subsea 7 that this was a product that would be ideally suited to a variety of the positioning challenges in their upcoming work for BP Angola on Block 31 PSVM. For their part Subsea 7 made several important technical suggestions that CDL have incorporated into the final system design, providing further usability in the field. The first units are scheduled to arrive in Angola in late spring and will be operational soon after.

Simon Waterfield, Subsea 7 Project Surveyor for Block 31 PSVM stated: "By deploying a MobIUS unit on to each hub Subsea 7 will be able to carry out heading, pitch and roll measurements of the hub and simultaneously carry out range measurements between the hubs in a single equipment deployment. This has the potential to save considerable vessel time during the numerous metrology operations which are part of the Subsea 7 scope of work. In addition the use of the MobIUS reduces the risk of disturbing metrology interface equipment as only a single deployment onto each hub is required."

Six units will be committed to Angola this year with the project expected to last well into 2011.
