Teledyne Webb Research Delivers Slocum G2 Gliders to DOF Subsea North America

Slocum G2 glider

Teledyne Webb Research has announced the recent sale and delivery of Slocum G2 gliders to DOF Subsea North America for use in commercial oil and gas-related applications. The Slocum gliders delivered to DOF Subsea are equipped with an environmental characterization optics (ECO) sensor, a conductivity, temperature and depth (CTD) sensor, and a Teledyne RD Instruments (Poway, CA) acoustic doppler current profiler (ADCP) for current profiling. All gliders are 1,000m-rated and feature an optional propeller to expand the operational envelope of the vehicle.

While approximately 500 Slocum gliders have been sold for academic and military applications, including fleets of gliders to the US Navy, Ocean Observatories Initiative (OOI) and the UK National Oceanography Centre (NOC), the deliveries to DOF Subsea are among the first Slocum gliders delivered to service providers in the oil and gas market.

Using remotely managed autonomous underwater vehicles (AUV) such as the Slocum glider will enable service providers to gather vital, near real-time water column data to improve situational awareness in operating areas at a fraction of the cost of traditional approaches employing surface vessels. Slocum gliders can be equipped with a choice of more than 40 different sensors and are capable of deployments lasting up to a year. These gliders maintain communications through a satellite link permitting data transfer and missions management remotely, making gliders an ideal tool for oil and gas applications.

"We are excited to be working with DOF Subsea and look forward to a long and mutually beneficial partnership."

DOF Subsea North America global AUV manager Sean M. Halpin said: "DOF Subsea selected the Slocum glider as our first platform for remotely managed AUV oil and gas operations due to its scalability, reliability and track record. The use of long-duration, remotely managed vehicles reduces the risk and cost of many of our present operations and therefore we believe that this type of platform has a bright future within DOF Subsea and the oil and gas industry. Two of our vehicles are already committed on a long-term project and we look forward to expanding our operations to suit market conditions."

Teledyne Marine Systems director of sales (vehicles) Arnar Steingrimsson said: "We are excited to be working with DOF Subsea and look forward to a long and mutually beneficial partnership. We will continue to work with DOF Subsea and other commercial survey users to optimize the Slocum glider for oil and gas applications and make the Slocum glider the ultra-long endurance AUV of choice for service providers."
