Refer to Seakeeper<\/span> Drawing No. 90256 \u2013 Seakeeper<\/span> 35\/30HD Bolt-In Installation Details. Important dimensional and load information is given in this drawing that will impact the design details of the structure that will receive the Seakeeper<\/span>. It is assumed that a proper structural analysis has been performed for the hull structure to which the Seakeeper<\/span> will be fastened to ensure proper strength margins for the loads the Seakeeper<\/span> will create during operation. <\/p>\n\n\n\n

The hull structure supporting the Seakeeper<\/span> should be arranged so the Seakeeper<\/span> is parallel to the waterline in the forward-aft and port-starboard directions . In addition, the four areas on top of the beams on which the isolation mounts will rest, need to be co-planar within 1\/8 in. (3 mm) to minimize potential distortion of Seakeeper<\/span> support frame when installed. (Similar to Figure 12).<\/span><\/p>\n\n\n\n

Seakeeper<\/span> provides an installation fixture assembly (P\/N 90089), which contains four plates that mimic the mating surfaces of the four isolation mounts located on the Seakeeper<\/span>\u2019s foundation. These plates have 8 holes located at the same centers as the holes in the isolation mounts. These smaller holes can be used to locate the holes in the ship\u2019s structure through use of a transfer punch or drill. The fixture locates the hole patterns at the proper spacing, both in the fore-aft direction and the port-starboard direction. See Figures 4 & 5 below. Once assembled, the fixture can be used to check clearances and alignment of the hull structure.<\/p>\n\n\n\n

Note: Do NOT use the installation fixture to establish Seakeeper<\/span> envelope dimensions. Refer to Drawing No. 90256 \u2013 Seakeeper<\/span> 35\/30HD Bolt-In Installation Details, for envelope dimensions. A 3-D model of the Seakeeper<\/span> is available on the Seakeeper<\/span> website (www.seakeeper.com<\/a>) to aid in designing the Seakeeper<\/span> foundation and the space around the Seakeeper<\/span>.<\/strong> See Figure 6 below.<\/strong><\/p>\n\n\n\n
