1.1 Precautions
- The Seakeeper 18 must only be lifted from the supplied lifting eyes (See Section 1.4), shown in Figure 1.
- The Seakeeper flywheel is supported by precision bearings. DO NOT drop or impart mechanical shock to the Seakeeper assembly while lifting or unpacking, 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 the finish could lead to early appearance degradation of the installed Seakeeper.
1.1.1 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.
__________________________________________________________________________________________________
Stand clear of the Seakeeper and all moving parts when operating.
__________________________________________________________________________________________________
The unit may be started remotely. Assume it could move without warning.
__________________________________________________________________________________________________
The Seakeeper and related structure should be treated with the same respect one gives a high-speed rotating propeller or engine shaft.
__________________________________________________________________________________________________
The following must be true before accessing the Seakeeper:
* Input power must be disconnected for at least 10 minutes
* The Seakeeper must be locked
* The flywheel must be at zero speed

- Reference Seakeeper Drawing 90667 – Seakeeper 18 Hardware Scope of Supply for items that ship with the Seakeeper.
- Remove electrical components, display, cables, and misc. items and set aside.
- Remove packing materials that secure Seakeeper assembly inside the crate.
- Remove top and angled face cover panels to access lifting eyes.
- Attach spreader bar (Seakeeper P/N 80061) to the two lifting eyes located on the top of the Seakeeper enclosure. Stay clear of any other parts on the Seakeeper. The Seakeeper 18 weighs 2,460 lbs (1,116 kg). See Figure 1 below.
- Only when ready to install in vessel, remove lag bolts from the Seakeeper foundation and prepare to lift the Seakeeper from the crate.
