Normal Shut Down

The Seakeeper should be stopped when pulling into port and stabilization is no longer required. This maximizes life by allowing the Seakeeper to start the coast down cycle before cooling is shutoff. Once the vessel is secured, the AC and DC breakers can be switched Off. The Seakeeper will continue to spool down to 0 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. Press the Seakeeper On/Off button. The On/Off button will turn grey. The Seakeeper will discontinue stabilization and the flywheel will start coasting.

2. 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 0 RPM. This can take 5+ hours from full speed. When the flywheel has stopped spinning, 0 RPM will appear on the screen.

The circuit breakers should be left on as long as possible while the Seakeeper is spinning to remove heat from the Seakeeper. During normal operation, the Seakeeper should be stopped when pulling into port and stabilization is no longer required. This maximizes long term life as it allows the Seakeeper to start the coast down cycle before cooling is shutoff. Once the vessel is secured in the slip and the crew has shut down the generator and engines, the AC and DC breakers that control the Seakeeper should be switched to the Off position. The Seakeeper will continue to spool down to 0 RPM. No cooling is required during this time. Note Seakeeper will take approximately 5+ hours to coast down to 0 RPM from full speed. The Display will indicate 0 RPM when the flywheel has stopped.

Note: The seawater pump may run for up to 5 minutes after the Seakeeper is switched off and is coasting (with AC power applied).
