SEAKEEPER 6 90402 1 8 of 8
Section 1: MECHANICAL INSTALLATION
1.5 Bolt-In Installation
1.5.1 Check and Preparation of Hull Structure
Refer to Seakeeper Drawing No. 90398, Seakeeper 6 Installation Details – Bolt in Method.
Important dimensional and load information is given in this drawing that will impact the design
details of the structure that will receive the Seakeeper. It is assumed that a proper structural
analysis has been performed for the hull structure to which the Seakeeper will be fastened to
insure proper strength margins for the loads the Seakeeper will create during operation.
The hull structure supporting the Seakeeper should be installed so the Seakeeper is parallel to
the waterline. In addition, the four areas on top of the beams on which the feet of the
Seakeeper foundation and isolation gaskets will rest need to be co-planar within .06” (1.5
mm) to minimize potential distortion of Seakeeper support frame when installed.
Seakeeper provides an installation template kit, P/N 90392, which contains four plates that mimic
the mating surfaces of the four feet located on the Seakeeper’s foundation. These plates have 4
holes located at the same centers as the mounting holes on the Seakeeper. The fixture locates
the hole patterns at the proper spacing both in the fore-aft direction and the port-starboard
direction. See Figures 5 below. Once assembled, the fixture can be used to check clearances
and alignment of the hull structure.
Note: Do NOT use the installation fixture to establish Seakeeper envelope dimensions.
Refer to Drawing No. 90398 for envelope dimensions. A 3-D model of the Seakeeper is
available on the Seakeeper website (www.seakeeper.com) to aid in designing the
Seakeeper foundation and the space around the Seakeeper.
NOTE: MAKE SURE NO OBSTRUCTIONS FROM THE HULL STRUCTURE CAN BE SEEN WITHIN THE INSIDE
OF THE INSTALLATION TEMPLATE KIT (INSIDE THE MARKED RED LINES). SEE SECTION 1, PAGE 9 OF
INSTALLATION MANUAL.
