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.
