Subsea Graphical Data Logger

The Jupiter Subsea Graphical Data logger System builds on the capability of existing Jupiter Subsea Displays.


The SGDS is designed to display the total number of sensor actuations on Subsea tools, modules & installations without the need for a complex control system or datalink.

Critical operations can be monitored and now data logged using an internal 32Gb Mass Storage Device (MSD).                Diagnostic capability allows the operator to test / confirm operation with customisable sensitivity level set-up.


Any displayed image automatically flips upright via an in built accelerometer and also logs this occurrence.


Facilities to log ‘Shock and vibration’ and upload data logs via IrDA ‘infra-red’ with configuration for the SGDS via external RS232 / USB host connections, will present the operator with a user-friendly GUI to configure parameters and execute functions.


The SGDS has 2 inbuilt light sensors that actuate the module only when illuminated by ROV lights or Rig Lights.  This allows the SGDS to remain dormant for years before operation.


The SGDS display shows key data such as battery status, system temperature, date / time.  The display is also highly configurable allowing custom text to be inserted as well as a bitmap such as a client logo and different text colour options to choose from.
