Saab Seaeye Panther Selected for Pipeline Inspection in Gulf of Mexico

For pipeline inspection in the Gulf of Mexico, global maritime, survey and ROV services operator ACSM chose an electric Saab Seaeye Panther XT robotic vehicle over other ROV vehicle alternatives. The Panther inspected 261 pipelines totalling 2,340km in four fields in the Gulf of Mexico (GOM), at depths ranging from 15 to 130 metres, in a less than 10-month project duration. ACSM chose the electric Saab Seaeye Panther because it can perform the full scope of work needed, yet is far smaller than hydraulic equivalents. Considerable savings come from deploying the 700kg Panther system rather than the much heavier hydraulic... (read more)

Optimizing the Choice of DVLs for Noisy Environments

Reliable navigation and positioning underpin productive use of submerged vehicles, leading to optimized operations, expanded capabilities, and greater cost-effectiveness. For 25 years, Teledyne RDI Doppler Velocity Logs (DVLs) have been an industry-leading solution for this need. DVLs are sonar systems that accurately measure a vehicle’s speed over ground and altitude above the seabed. The high precision and fast update rates of Teledyne RDI’s data have enhanced subsea operations, from high-resolution spatial surveys to low-altitude stationkeeping. Moreover, Teledyne RDI DVLs have delivered robust navigation over highly demanding terrain, such as rugged hydrothermal vent fields on mid-ocean ridges. Field Trials To operate... (read more)

AUV and ROV Technology Plays Key Role in Historic Discovery

WWII Wreck Located in South Pacific
An underwater research and exploration vessel has played a key role in locating a major US aircraft carrier lost during World War Two. The R/V Petrel, owned and operated by philanthropist Paul Allen, discovered the remains of the USS Hornet on the seabed, 5,330 metres below the surface of the South Pacific Ocean near the Solomon Islands in late January 2019. This article looks more closely at the importance of underwater technology in enabling this historic find. The R/V Petrel is an expedition ship belonging to Vulcan Inc, a company founded by explorer and philanthropist Paul G. Allen, co-founder of Microsoft... (read more)
