Section 4: STARTUP
6) The sea water pump should have started when the ON/OFF button on the display was
depressed. Confirm pump operation and flow rate, if practical. Required flow is 4 GPM
(15 LPM) minimum and 8 GPM (30 LPM) maximum.
7) Verify that there are no ALARMS present. If an ALARM is present it will be displayed.
8) When the Seakeeper reaches its maximum operating speed where maximum stabilization
is available, the progress bar will disappear and the Seakeeper is available for maximum
stabilization. Press the stabilize button. The button will turn blue indicating that
the Seakeeper is stabilizing the roll motion.
9) Verify that there are no alarms. If an ALARM is present it will be displayed.
10) Press the STABILIZE Button to turn stabilization off. Then press the Seakeeper
ON/OFF Button to power the Seakeeper down.
11) During normal operation, the Seakeeper should be stopped when 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
zero rpm. No cooling is required during this time. Note the Seakeeper 9 will take 4+ hours
to coast down to zero rpm from full speed. When the flywheel has stopped the display will
indicate 0 RPM.
