INSTALLATION
MANUAL
Section 1: MECHANICAL INSTALLATION
1.1 Precautions
• The Seakeeper 9 must only be lifted from the supplied lifting eyes (See Section 1.4).
• The Seakeeper flywheel is supported by precision bearings. While unpacking and lifting
the Seakeeper assembly DO 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
the bottom of the Seakeeper enclosure to contact 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 surfaces 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:
1. 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.
2. Adequate service access for scheduled maintenances and overhaul of
the Seakeeper 9 is required. See Figure 2 and 90225 – Seakeeper 9/7HD
Bolt-In Installation Details for service clearance requirements.
3. The Seakeeper should be installed in a dry space to minimize effects of
corrosion.
