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.
Key Features
