INSTALLATION
MANUAL
Section 1: MECHANICAL INSTALLATION
Safety
There is a large torque about the gimbal axis when the Seakeeper is
precessing. Seakeeper cover panels are 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 is at 0 RPM.
The Seakeeper and related structure should be treated with the same respect one
gives a high-speed rotating propeller shaft or engine shaft.
Noise/Soundproofing
Seakeeper 9 noise has been measured under steady state conditions (no wave load) in
Seakeeper's lab and in our test boat. The steady state noise is typically in the range of 70-75 dB
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
machinery space, lazarette, or bilge. If additional noise reduction is needed sound proofing
insulation can be used in the space around the Seakeeper unit.
