[email protected] www.sonardyne.com Datasheet Dynamic Positioning Transponder 6 (DPT 6) Description Typical Applications DPT 6 is designed to be used as a seabed reference transponder by USBL and LUSBL acoustic positioning systems, installed on many Dynamically Positioned (DP) vessels. • DP vessel positioning The DPT 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 DPT 6 help de-risk subsea operations and save vessel time and cost. The Type 8301 DPT 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. Several depth ratings are available: 3,000 m, 5,000 m and 7,000 m, all hard anodised aluminium alloy with protective polyurethane sleeve. Midi (shorter) and Maxi (long endurance) options are also available. The DPT is fitted as standard with a highly reliable release mechanism to enable the unit to be deployed in a flotation collar and recovered to the surface without ROV intervention. DPT 6 is fully compatible with all of Sonardyne’s latest 6G® equipment including Sonardyne’s Marksman LUSBL and Ranger 2 USBL systems. • Rig positioning • Drill string monitoring Key Features • MF frequency band utilising Sonardyne Wideband®2 ranging and telemetry protocols • Dramatically faster and easier to set-up and operate • Robust acoustic performance in noise and multipath conditions • Real time diagnostics available on ranges to enable quality control • Reduced mutual interference to further improve simultaneous ops • Advanced multi-user/multi-vessel capability • More than 500 unique Sonardyne Wideband®1 and 2 channels • Sonardyne Wideband® 1 and HPR400 USBL mode compatible • Automatic power-down if not used for a programmable period • Highly reliable release mechanism • Omni or directional transducer • Standard sensors: temperature, pressure and MEMS inclinometer • Optional sensors: Paroscientific DigiQuartz pressure sensor, inclinometer and sound velocity • Real time diagnostics available on ranges to enable quality control • Field proven Designed for: Sonardyne Global Headquarters T. +44 (0) 1252 872288 F. +44 (0) 1252 876100 E.
