Heavy Load DORT Acoustic Release Transponder
Description
The Type 8048 Heavy Load DORT
(Deep Oceanographic Release
Transponder) is a tough, reliable
acoustic release designed for
deployment in up to 7,000 metres of
water.
Standard features include a Safe
Working Load of 2,500Kg and a
spring-assisted release mechanism.
This type of release mechanism was
originally developed by Sonardyne
for navigation transponders supplied
to the offshore industry of which
there are now many thousands
reliably in service around the world.
Key Features
• Safe Working Load of 2½ Tonnes
• 7,000 Metre depth rated
• Highly reliable, proven release
mechanism
• Up to 3 years deployment
• Excellent corrosion resistance -
Ferralium 255
• Compact and rugged design
• Mechanically compatible with
other release transponders
• Choice of housing lengths to suit
deployment scenario
Excellent corrosion resistance is
achieved by using Super Duplex
stainless steel, Ferralium 255. In
addition, the Heavy Load DORT is
available in different housing lengths
and is mechanically compatible with
other standard release transponders
on the market thus simplifying
mechanical integration.
Heavy Load DORTs are controlled
using frequency band specific
Lightweight Command Units (LCU)
which comprise of a dunking
transducer connected to either a
splash-proof PSION, PC running
supplied software or terminal
program. For security of operation, a
special coding system provides
protection against accidental release
by noise and acoustic transmissions
from other vessels.
