The company has upgraded the Ranger 1 system installed on the SEAMEC Princess to Sonardyne’s current generation USBL (Ultra-Short Baseline) platform, Ranger 2 Pro, the highest specification system available.

Ranger 2 builds on the simplicity and reliability of Sonardyne’s original Ranger system adding support for 6G (Sixth Generation) acoustic instruments and Wideband 2 signal architecture. These exclusive technologies are proven to deliver stable positioning for DP operations, low cost of ownership, faster subsea operations and hardware that is easier for users to set up and operate.
In its role as a DSV, maintaining a constant vessel position during subsea operations is a critical requirement for the SEAMEC Princess. As such, Ranger 2 Pro was specified for its ability to operate with a network of transponders deployed on the seabed that offer positioning redundancy in all operating conditions.

“We have used Sonardyne’s Ranger technology for many years so when the time came to bring the system up to date, the operational and performance gains offered by Ranger 2 made the decision a simple one,” commented KT Thomas, DGM (Tech) for SEAMEC Limited. “The nature of the work carried out by the vessel demands that our DP system is continuously fed with good quality position reference data. By opting for Ranger 2 in Pro configuration, we’ll be able to meet this requirement.”

Daniel Tan, Regional Sales Manager for Sonardyne Asia commented, “We have a long standing relationship with SEAMEC so we’re pleased to continue supporting them with the latest technology solutions that will improve the efficiency of their subsea operations, reduce vessel time and generate savings for the company and its clients.”

”The fleet owners were very enthusiastic about our commitment to their employees’ safety, and they can see a major advantage in being able to call on the knowledge we have built up over a number of successful projects. This has lead to a great deal of valuable product optimizations, which means that we can now deliver very safe but still cost-effective solutions to customers.”
