Two Sonardyne Ranger 2 USBL (Ultra-Short BaseLine) acoustic positioning systems have been purchased by Ashtead Technology in Singapore as part of a multi-million pound investment programme in the latest subsea technology. Ashtead Technology has chosen the high specification Ranger 2 Pro variant and complementary Wideband Mini Transponders which are now available to rent in Asia for the first time.
Ranger 2 is designed for deep water, long range tracking of underwater targets such as ROVs and also position referencing for dynamically positioned (DP) vessels. The new version builds on the simplicity and performance of Sonardyne's original Ranger system by adding support for the company's latest sixth generation (6G) acoustic instruments, Wideband 2 signal architecture and Lodestar inertial navigation sensors. These technologies enable multiple subsea targets to be positioned with survey-grade accuracy in any water depth while reducing operational time and vessel costs.
During a recent visit to Sonardyne's offices in Singapore, Neil Christie, regional director of Ashtead Technology, was enthusiastic about the benefits Ranger 2 will offer his customers in the region. He said: "The Ranger 2s we now have on the shelf are easy to set-up and use and deliver the highest levels of precision and performance. The equipment can be quickly installed on vessels-of-opportunity so that our clients can get up and running with their subsea projects without delay."
Ranger 2 is manufactured at Sonardyne's headquarters in Yateley, southern England. The company has regional operating subsidiaries in Aberdeen, Singapore, Houston, and Brazil and is recognised as a world leader in the design and manufacture of underwater acoustic positioning, inertial navigation, subsea communications and sonar technology systems for the offshore oil and gas, ocean scientific and maritime security industries.
