[email protected] www.sonardyne.com Datasheet Dynamic Positioning Transponder 6 with Inclinometer (DPTi 6) Description Typical Applications The Type 8301 Dynamic Positioning Transponder with dual-axis inclinometers (DPTi) is designed to monitor the angle of the riser flex joint on a drilling vessel. • Riser angle monitoring The DPTi 6 supports Sonardyne Wideband®2 acoustic ranging and telemetry providing high accuracy positioning, robust performance in noisy and multipath conditions and easy set-up and use. With hundreds of channels, less interference to and from other acoustic systems and multi-user capability, Sonardyne Wideband®2 enables easier SIMOPS vessel capability. These features of the DPTi 6 help de-risk subsea operations and save vessel time and cost. The Type 8301 DPTi 6 is the standard length version and is based on the field proven mechanics of the previous version but with improvements to the end-cap closure mechanisms. The design offers the perfect balance between size, acoustic output and battery life. The DPTi 6 is fitted with internal inclinometers to accurately monitor riser angles. The unit can also be used with an external inclinometer unit to monitor BOP and flex joint angles. DPTi 6 is fully compatible with all of Sonardyne’s latest 6G® equipment including Sonardyne’s Marksman LUSBL and Ranger 2 USBL systems.
