Interlock Panel – the smart option for retrofit

With nearly 150 completed retrofit projects, Optimarin knows where the challenges lies. One of the challenges are to gather signals from pumps and valves that can bypass the BWTS.
Please welcome the solution: “Interlock Panel”.
Key features:

  • External valves and pumps makes it difficult to install a BWTS to be in compliance with the requirements. The guidelines states:
    «Any bypass of the treatment system shall activate an alarm, and the bypass event shall be recorded by the control equipment of the treatment system»
  • Each “Interlock Panel” can receive signals from up to 16 pumps and/or valves pr. panel
  • Can handle up to 24 different illegal bypass routings (states)
  • The illegal bypass routes are easily configures at commissioning thanks to the unique settings pages in the OBS Touch Panel.

The interlock logic – the unique pages in the OBS Touch Panel. The crew can easily identify valves positioned incorrectly.

Identifying illegal bypasses:

The two orange marked valves will open up a direct line between over board and the ballast tanks.

The two red marked valves enables gravity filling from sea chest.

Can be replaced by IAS solution.
