Heavy Duty Acoustic Release Frames
In order to increase
the Safe Working Load (SWL) of a standard ORT, DORT, Heavy Load
DORT, P-DORT and Heavy Load Compatt 5,, Sonardyne offer a range
of heavy duty release frames. The frames act as a load amplifier
so that only a fraction of the mooring load passes through the acoustic
release. Applications include: offshore construction, marine salvage,
defence and oceanographic research.

Manufactured from high strength
steel which is galvanised and painted, the release frames
offer excellent corrosion resistance and are suitable for
long term deployment. This can be up to three years if the
acoustic release is fitted with a lithium battery pack.
Depending on the type of
acoustic release being used, the SWL of the unit can be
increased up to 50 tonnes. All the frames can be easily
assembled in the field and in most cases, fitted without
any modification to the transponder itself. Custom frames
for special applications or higher load ratings are available
on special request.
