Figure 3: Seakeeper 1 Service and Operating Clearances (Drawing No. 90516)
Note: Adequate access to remove the Seakeeper 1 cover must be incorporated into the installation
design to allow for regular maintenance, service, and repair of components.
1.2.1 SAFETY
There is a large torque about the gimbal axis when the Seakeeper is precessing. The Seakeeper 1
enclosure is provided to prevent personnel or equipment from contacting the Seakeeper while it is in
operation. These covers should not be stepped on or have anything placed on top. The covers should
always be in place during operation. If it is ever necessary to access the Seakeeper while the flywheel
is spinning, the Seakeeper must be locked at the display to stop the Seakeeper from precessing.
Seakeeper regular scheduled maintenance should only be performed by authorized personnel when
the Seakeeper is locked and the flywheel has stopped spinning.
1.2.2 NOISE / SOUNDPROOFING
Seakeeper noise has been measured under steady state conditions (no wave load) in Seakeeper's
Engineering Lab and in our Factory Demo Boat. The steady state noise at 1 meter is typically in the
range of 62-64 dBC un-weighted. As the frequencies emitting the highest sound pressures are low
(like other marine machinery), it is recommended that the Seakeeper be installed in an enclosed space
such as a leaning post / seat, bilge, center console, or machinery space.
