Sonardyne’s SPRINT for MMT’s Surveyor Interceptor

Sweden’s MMT selected Sonardyne’s acoustically aided inertial navigation system, SPRINT for its 2,000 metre rated remotely operated vehicle, Surveyor Interceptor.

Designed for subsea vehicles, Sonardyne believes, SPRINT makes optimal use of acoustic aiding data including USBL, LBL and Doppler Velocity Log (DVL) and other sensors such as pressure sensors to improve accuracy, precision, reliability and integrity in any water depth.

The accuracy of SPRINT complements the vehicle’s imaging and mapping sensors, resulting in improved survey data quality and substantially reduced ‘cost per kilometre’ of surveys.

On the Survey Interceptor, a Sonardyne Inverted Ultra-Short BaseLine (iUSBL) transceiver has been interfaced directly to the SPRINT resulting in a highly optimised navigation solution that delivered position updates up to 100 times a second.

Alan Macdonald, Sales Manager for Sonardyne, commented: “We are obviously delighted with the outstanding results that MMT has achieved using SPRINT, both in testing and more recently, during its first commercial operation. At a time when the offshore industry is focussed on ways to reduce costs without compromising on quality, the combination of MMT’s ground-breaking ROV and our SPRINT INS represents a unique offering to the construction survey marketplace.”

Jonas Andersson, R&D Manager at MMT, said: “When testing the new MMT Survey Interceptor ROV, we were looking for an inertial navigation solution that would deliver real-time performance with high speed updates. By running Sonardyne’s SPRINT inertial navigation system we witnessed a marked difference in the accuracy of all ROV positioning activities during the period, which in turn made a marked difference to the quality of the survey data received.”

“Now that Sonardyne has also released their new Syrinx DVL, we will be looking to run further tests in the future. This will be done with a view to achieving even more precise position accuracy using a tightly integrated Syrinx DVL, SPRINT and USBL acoustics,” Andersson concluded.

6th Offshore Well Intervention Conference Gulf of Mexico

The Offshore Well Intervention Gulf of Mexico conference (OWI GOM) is returning to Houston, Texas for its sixth year on Wednesday 20 – Thursday 21 November.

Featuring Anadarko, BP, Shell, Chevron, BHGE and Oceaneering, the conference aims to help operators transition to the latest compliance updates, WI systems and business models that enhance safety, quicken well access and improve commerciality.

Across two days, more than 200 delegates, 15 exhibitors and 30 speakers will network together and create solutions to some of the most pertinent industry challenges right now, through a conference programme focused on:

  1. Clarifying compliance updates
  2. Quicker well access and safer well control
  3. ​Understanding HPHT well intervention (systems)
  4. Forecasting well intervention activity, discussing new commercial models and comparing platform options
  5. Best practice riserless well intervention
  6. ​The latest well intervention equipment
