The Seakeeper<\/span> 18 can be affixed to the hull structure using two methods:<\/p>\n\n\n\n

    \n
  1. Bolt-in installation or<\/li>\n\n\n\n
  2. Bond-in (Saddle) installation. <\/li>\n<\/ol>\n\n\n\n

    Both are shown in Figures 7 and 8 with clearances required.<\/p>\n\n\n

    OPTION 1 – DIRECT FASTENING OF SEAKEEPER FOUNDATION TO SHIP’S STRUCTURE<\/strong><\/h3>\n\n\n\n

    Option 1 would be applied when a metal structure or laminated tapping plates are available for attachment. The Seakeeper<\/span> 18 frame would fasten directly to hull structure or plates using isolation gaskets for metal-to-metal contacts and sixteen M14-2.0 fasteners. Depending on the structure to which the Seakeeper<\/span> is fastened, blind threaded holes or thru-bolting can be utilized.<\/p>\n\n\n

    OPTION 2 – SADDLE INSTALLATION (4 PLACES)<\/strong><\/h3>\n\n\n\n

    Option 2 would most commonly be used on a FRP hull structure. For this option, four 12.9 in. (327 mm) long x 4.9 in. (125 mm) wide x 6.7 in. (170 mm) height saddles (P\/N 90547) are bonded to properly spaced and prepared structural members that are an integral part of the hull structure. Seakeeper<\/span> recommends using a structural adhesive with a lap shear strength of 2,000 psi (13.8 MPa) or greater. Careful consideration should be exercised by the installer while selecting the appropriate adhesive.  Compatibility with the Seakeeper<\/span>\u2019s cast aluminum A356-T6 saddles, hull structure and pot life are three important factors to consider. Proper surface preparation in accordance with adhesive manufacturer\u2019s recommendations prior to installation is very important. Recommended adhesives can be found in Seakeeper<\/span> Technical Bulletin 90382<\/strong> \u2013 Structural Adhesive Recommendations<\/em>.<\/p>\n","protected":false},"excerpt":{"rendered":"
