develogic subsea systems

Deep Water Release Module – DW.Release

Description

The develogic DW.Release is suitable for applications in ocean bottom landers or
mooring systems.

Interfaced to one of our acoustic modems, the release module provides all
the functionality of an acoustic release, deployed as a standalone system it
can be set to release at a preset time or event or controlled via its RS232
interface.

The system is depth rated to 6,000m with a safe operating load of 5kN and a
breaking load of 25kN.

Different trigger options are configurable

- at a pre-programmed time
- after a certain delay after landing on the seafloor (detected via the internal acceleration sensor)
- when the units inclination after landing is outside pre-programmable limits (due to obstacles on the seafloor)
- when the unit is moved after landing on the seafloor (e.g. when it is caught in a trawl net)
- via the serial interface of the unit
- upon loss of external power supply or system leakage
- via our HAM.Base acoustic modem
