Survey Equipment Services Inc. (SES) said it strengthened its lease pool in the Gulf of Mexico by continuing its investment in Sonardyne 6G subsea positioning technology. This latest acquisition is for a Ranger 2 subsea tracking system, the fifth delivered to SES since the beginning of 2013, and made available for use with the Sonardyne GyroUSBL transceiver and Wideband Mini Transponders (WMTs) already owned by SES.
Ranger 2 is a survey grade USBL acoustic positioning system designed for deep water, long range tracking of underwater targets and position referencing for dynamically positioned vessels. The system calculates the position of a subsea target by measuring the range and bearing from a vessel-mounted transceiver to an acoustic transponder fitted to the target. Multiple subsea targets over a wide area and range of water depths can be simultaneously and precisely positioned. It builds on the simplicity and performance of the company’s original Ranger system but adds support for Wideband 2 digital signal architecture which speeds up subsea operations.
