YATELEY, UK – PDE Offshore Corp. has selected Sonardyne Asia Pte Ltd. to support its work on wind farm construction projects offshore Taiwan.
The company has ordered a Mini-Ranger 2 ultra-short baseline (USBL) system and wideband sub-mini 6+ (WSM 6+) transponder/responders to accurately track the position its underwater equipment, which includes a seabed frame used to guide geotechnical corers.
The Mini-Ranger 2 will be installed and operated from PDE Offshore’s 72-m (236-ft) long survey vessel MV Geo Energy, which is scheduled to spend this summer working in the Taiwan Strait, evaluating proposed locations for turbine foundations.
Mini-Ranger 2 is built around the company’s 6G hardware and Wideband 2 digital acoustic technology platforms. At its heart is HPT 3000, a surface-deployed USBL transceiver optimized for performance in shallow water, as well as high elevation and long lay back operating scenarios and data telemetry.
The size and positioning performance of WSM 6+ makes it a transponder choice for fitting to and tracking underwater vehicles and equipment, according to Sonardyne. Its built-in depth sensor improves USBL precision, while a responder mode allows fast moving targets to the tracked at the highest possible update rate.
