[email protected] www.sonardyne.com Datasheet Heavy Duty Acoustic Release Frames Description Key Features The Heavy Duty Acoustic Release Frames have been designed as optional extras for Sonardyne's popular Type 7409 Oceanographic Release Transponders (ORTs) and Type 7710 Deep Oceanographic Release Transponders (DORTs). Safe Working Load of 7.5 or 25 tonnes The Type 7869 release frame increases the Safe Working Load (SWL) of a standard ORT or DORT to 7½ tonnes (at 4:1 safety factor) with a breaking load of 30 tonnes. The Type 7988 release frame has a SWL of 25 tonnes and breaking load of 100 tonnes. In most cases both types of release frame can be fitted without any modification to the acoustic release itself and is easily assembled in the field. Manufactured from high strength steel which is galvanised and powder coated, the releases offer excellent corrosion resistance for long term deployment. This can be up to 3 years when the ORT or DORT is fitted with a lithium battery pack. Depth rating is solely dependant upon the acoustic release being used; 2,000 metres for an ORT or 6,000 metres for a DORT. Applications for which the acoustic releases have been developed include; marine salvage, defence and oceanographic research.
