Section 2: SYSTEM OPERATION
2.4 Normal Shut-Down
The Seakeeper should be stopped when stabilization is no longer required. Once the
vessel is secured, the AC and DC breakers can be switched OFF. The Seakeeper will
continue to spool down to zero rpm. No cooling is required during this time.
Note: The seawater pump may run for 5 minutes after the Seakeeper is switched off and
is coasting (with AC power applied).
1) Verify that no alarms are on the Seakeeper display.
2) Press LOCK/UNLOCK button. The LOCK symbol will turn RED
3) Press Seakeeper ON/OFF button. The ON/OFF symbol will turn RED. The Seakeeper
will start coasting.
When the flywheel has stopped spinning 0 RPM will appear on the screen
4) Once the vessel is secured in the slip and the crew has shut down the generator and
engines, switch the AC and DC breakers that control the Seakeeper OFF. The flywheel
will continue to spool down to zero rpm. This can take 4+ hours from full speed.
