Key Cabinet Systems
Having implemented a good interlock control system, the next most important step is to apply a good Key Management System.

For storage, ease of access and issue, SFC key cabinets provide all that is required.

A key cabinet should be located in a safe place; typically a control room whereby initiating keys are issued by the Shift Supervisor, Offshore Installation Manager (OIM) or other person in authority.

Cabinets vary in size and can accommodate from 1 - 227 system initiating (or spare) keys.

 
Keys can be located via means of hooks or holsters. (The Holster locator provides increased capacity and unique 'coded' locations).

Each interlocked system has a dedicated tag location within the key cabinet. During periods of normal operation, all interlock system 'permit' (initiating) keys are visually displayed within the cabinet in dedicated locations.

Each key cabinet tag is labeled with the relevant piping package data - this same data is also replicated on the system key.

 
 

When the key is removed, a 'Visual Alert' tag is revealed providing details of the key which has been issued, its designated location, and the words "WORK IN PROGRESS".

Control Room staff have clear and easy indication of work status at any time.

Key cabinets can also accommodate mimic diagrams. These are extracts of the P&ID diagram engraved onto a traffelite plaque and show clear details of all valves which are interlocked.
