PDE Offshore Corporation upgrades underwater acoustic positioning system


PDE Offshore Corporation, a Taiwanese offshore geophysical and geotechnical investigation company, has upgraded its underwater acoustic positioning system onboard MV Geo Energy to Sonardyne’s Ranger 2 USBL system. This will further enhance its capability in the exploration of offshore renewable energy (ORE) in Taiwan.

Its new geotechnical vessel Geo Power, also equipped with Ranger 2 USBL system, is now under conversion work and will join the fleet in mid-2024. It will provide both seabed and downhole cone penetration testing services.

PDE Offshore has been conducting geotechnical and soil investigation in the shallow waters of the Taiwanese Strait since 2017 as the country looks to replace its coal-based energy with cleaner, sustainable alternatives such as offshore wind farms.

Working with most of the world’s leading ORE developers, PDE Offshore wants to increase its capability. This required a trusted and proven USBL positioning system for its Geo technical vessel to work in greater water depths and challenging water conditions as their operations expanded.

Having already successfully used Sonardyne’s Mini Ranger 2 for several years, investing in the full Ranger 2 system was a logical choice to provide the reliable dynamic positioning references essential for their operations, while also giving the capability for operating in greater depths and more challenging conditions.

Incorporating more than 30 years of USBL knowledge, Sonardyne’s Ranger 2 system is anything but standard. It can be used to track anything, in any depth, from any vessel.

It can track a subsea asset, position or communicate with an underwater vehicle, dynamically position your vessel – or do all of this simultaneously. It can be used for both survey and construction phases of ORE and supports complex tracking scenarios such as structures and vehicles with multiple transponders and multiple remote offsets.

“We have been working with Sonardyne since 2017 using their Mini Ranger 2 system,” said Huang Hsin-chih, PDE Offshore president. “The system is proven, reliable, and our engineers are familiar with its operation. It was a simple and logical choice to go ahead and upgrade to the Ranger 2 system to improve our capability to take on greater projects in the region.”

“Taiwan’s ambitions of becoming a green island means it is fast becoming a leading player offshore wind in Asia Pacific,” said Dan Tan, Sonardyne in Singapore regional sales manager. “We’re pleased to be a part this energy transition through PDE Offshore’s continued confidence and investment in our products. We look forward to supporting them in their future operations.”
