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 maintenance should not be
attempted unless the Seakeeper is locked and the flywheel has stopped spinning.
The Seakeeper should be treated with the same respect one gives a high-speed
rotating propeller shaft or engine shaft.
Noise/Soundproofing
Seakeeper noise has been measured under steady state conditions (no wave load) in
Seakeeper's lab. 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 a machinery space that is already treated with
soundproofing.
