  • Page 3: System Overview

    Seakeeper’s web site at www.seakeeper.com. The Seakeeper web site also contains videos of Seakeeper operation and videos of several different boats operating in waves with the Seakeeper on and off. It is recommended that the reader play these videos prior to reading the remainder of this manual.
  • Page 4 +/- 70 degrees about this position. The amount of torque that the Seakeeper exerts on a boat’s hull to counter the wave induced roll is directly proportional to the precession rate. The further the sphere is from vertical (zero degrees) the lower the anti-roll torque.
  • Page 5 Do not operate the Seakeeper without these safety shields in place. If it is ever necessary to touch the Seakeeper while the flywheel is spinning, the Seakeeper must be locked at the display to stop the Seakeeper from precessing.
  • Page 6 This foundation transfers the loads that the Seakeeper produces to the hull structure. An active hydraulic brake mechanism is located on the Seakeeper assembly to regulate the Seakeeper’s precession motions about the gimbal shaft. It includes four hydraulic cylinders and a hydraulic manifold.
  • Page 7 Section 1: SYSTEM OVERVIEW 1.2 Display The display shown below is the user interface to the Seakeeper 35 and should be mounted at the primary helm station. It is used to start, operate, monitor and shutdown the Seakeeper. Sensors, alarms and shutdowns are provided to allow unattended operation.

    Section 1: SYSTEM OVERVIEW 1.3 Drive Box The glycol/water mix that cools the Seakeeper is also circulated through a cold plate inside the Drive Box to remove heat from high-power electronic components. The Drive Box contains hazardous voltage and the cover should not be removed while the flywheel is spinning and the AC input voltage is present.
  • Page 9 Locking solenoids are installed in the circuit to lock the Seakeeper so it cannot precess if there is a leak in the circuit or a mechanical problem with the Seakeeper.

From left to right, the available pages are home, settings, information, service and alarm history. The selected page is highlighted in blue on the menu bar.
  • Page 14 Change the speed of the Seakeeper between normal operation and low power operation. The selected speed is colored blue. When power is cycled (or Seakeeper turned Off), this speed will default back to the normal operating speed. Speed selection buttons shown below are examples and may not match operating speed of installed Seakeeper.

The selected units are colored blue. 6) The information page displays the Seakeeper model, Seakeeper serial number, Seakeeper software versions, RUN hours, and SEA hours, and other information. 7) The service page displays operating information from the Seakeeper.
  • Page 16 3) Turn on the boat’s AC circuit breaker that supplies power to the Seakeeper. 4) In most cases, the seawater pump will be wired to turn on when the Seakeeper is turned on. However, in some cases the seawater pump is on a separate AC or DC circuit breaker and it is necessary to turn it on.
  • Page 17 For stabilization after the Seakeeper is ON and above the minimum operating speed: 1) Press the stabilize button. The button will turn blue indicating that the Seakeeper is stabilizing the roll motion. The stabilization mode starts gradually; it takes 5-10 seconds...
  • Page 18 It takes approximately 5+ hours for the speed to drop to zero rpm. If it is necessary to stop Seakeeper motion for any reason press the LOCK/UNLOCK button. The LOCK symbol will turn RED indicating that the Seakeeper is locked. Never attempt to work on the Seakeeper until the flywheel has stopped spinning.

  • Page 19: Normal Shut-Down

    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).
  • Page 20 The Display will indicate 0 RPM when the flywheel has stopped. Note: The Seawater pump may run for 5 minutes after the Seakeeper is switched off and is coasting (with AC power applied).
  • Page 21 1) Press the menu button then select the settings screen. 2) Select the desired RPM button to adjust the Seakeeper’s speed. The selected RPM button will turn blue. a. Seakeeper 35: Normal operational speed is 5150 RPM. Quiet mode operates at 4000 RPM, which allows stabilization at a reduced flywheel speed.

  • Page 22: Power Failures

    24 Volts DC powers the Seakeeper for all the control electronics. • 208 - 230 Volts AC powers the Motor Drive Box to drive the motor inside the Seakeeper. These are supplied on Cables 1 and 2 which are shown on Seakeeper drawing 90288, Cable Block Diagram.
  • Page 23 230 VAC Fluctuation, Spike or Momentary Failure If the AC voltage to the Motor Drive Box is outside Seakeeper’s specified range (208 – 230 VAC), the Motor Drive Box will briefly shut down for protection. The Motor Drive Box will continue operation when the voltage returns to the specified range.

  • Page 26: Maintenance

    Scheduled Maintenance to keep the Seakeeper running trouble- free. If the Seakeeper is installed in a wet space, efforts should be made to keep the Seakeeper free of salt residue from either condensation or direct exposure to salt spray. If exposed, a regular wipe down with mild soap and water with a rinse will help limit corrosion and keep the Seakeeper assembly in good cosmetic condition.
