Section 1: MECHANICAL INSTALLATION
1.1
Precautions
The Seakeeper must only be lifted from the supplied lifting eyes (See Section 1.4).
The Seakeeper flywheel is supported by precision bearings. Make certain while
unpacking and lifting the Seakeeper assembly to NOT drop or impart mechanical shock
as damage to bearings could result.
While handling / installing the Seakeeper assembly, protect exposed hydraulic brake
cylinder rods (See Figure 1) from scratches or damage as this could lead to premature
seal failure and oil leaks.
While handling / installing the Seakeeper assembly, do not allow electrical fittings that
exit bottom of the Seakeeper enclosure to come in contact with any surface or object as
this could damage the fittings and potentially affect the vacuum integrity of the
enclosure.
Exercise care to protect the painted finish as damage to finish could lead to early
appearance degradation of the installed Seakeeper.
1.2 Selection of Seakeeper Installation Location
Selection of mounting location of the Seakeeper should consider the following desirable
features:
The Seakeeper should be installed aft of amidships to minimize high
acceleration loadings due to hull/wave impacts during operation at
high speed or in large waves. If the only possible Seakeeper location
is forward of amidships then the installer should have Seakeeper
review the installation location prior to finalizing the design.
Overhead access or sufficient clearance for removal / re-installation of the
Seakeeper for overhaul in future years.
The Seakeeper should be installed in a dry space to minimize effects of corrosion.
Clearance for replacement of gimbal angle sensor on the Seakeeper gimbal shaft (see
Figure 2).
Clearance for filling / purging brake hydraulic oil (see Figure 2).
Clearance for filling water/glycol cooling circuit (see Figure 2).
Clearance for replacement of brake hydraulic cylinders (see Figure 2).
