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 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 and in our test boat. The steady state noise is typically in the range of 64-66
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 a machinery space
that is already treated with soundproofing.
