  • Page 3 This document is intended to give details and guidance to a boat builder or equipment installer to install the Seakeeper 6 Stabilization System. The Seakeeper is capable of producing loads up to 17 KN (3820 lbs.) at each of the four mounts and careful consideration should be given to foundation design to insure it is capable of transferring these loads into the hull.
  • Page 4 While handling / installing Seakeeper assembly, do not allow electrical fittings that exit bottom of Seakeeper enclosure to come in contact with any surface or object as this could damage the fittings and potentially affect the vacuum integrity of the enclosure.

  • Page 7 Seakeeper noise has been measured under steady state conditions (no wave load) in Seakeeper's lab and in our test boat. The steady state noise is typically in the range of 70-75 dB un-weighted. As the frequencies emitting the highest sound pressures are low (like other marine machinery), it is recommended that the Seakeeper be installed in a machinery space that is already treated with soundproofing.
  • Page 8     Selection of Installation Method The Seakeeper 6 can be affixed to the hull structure using two methods 1) Use bolt-in installation or 2) saddle installation. See figures below. OPTION 1- DIRECT FASTENING OF SEAKEEPER FOUNDATION TO SHIPS STRUCTURE Option 1 would be applied when a metal structure is available for attachment.
  • Page 9 4) Remove top and angled face cover panels to access lifting eyes 5) Attach spreader bar to the two lifting eyes located on the top of the Seakeeper enclosure. Stay clear of any other parts on the Seakeeper. Seakeeper 6 weighs 395 kg (870 lbs).
  • Page 10 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.
  • Page 11     CAUTION: Tight clearances from cable guide bands and brake side gimbal shaft to hull structure. See below for brake side gimbal shaft clearance. See above figure for dimensions and reference Seakeeper drawing NO. 90398 for complete Seakeeper envelope.
  • Page 12 1.5.2 Transfer of Holes to Boat Structure 1) Lower assembled fixture onto hull structure. The four areas where the feet of the Seakeeper will rest should be coplanar to within .06” (1.5mm). See Figure 9. 3) Align fixture in desired location and transfer holes from fixture plate to the foundation structure.
  • Page 13 2) Lower Seakeeper into position onto foundation beams and align over drilled holes. 3) Install Seakeeper supplied M12X1.75 – 70mm fasteners– apply a moderate coat of removable thread locker to the threads of each bolt and include a small bead of marine sealant under each washer before installation.
  • Page 14 Refer to Seakeeper Drawing No. 90399, Seakeeper 6 Installation Details – Bond 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 as well as selection of the adhesive to bond the Seakeeper into the hull.

  • Page 17 2) Mask hull area (Fig 9) around foundation saddles for easy clean-up and to create outline of surface area to receive adhesive as (Fig 8). Insure that the bond gap is within Seakeeper’s recommended thickness, or 3mm if using Plexus MA590. FIGURE 9 - MASKING PERIMETER OF SADDLES 3) Raise fixture clear of foundation.
  • Page 18 5) Remove any paint or gel-coat from bond surfaces so that adhesive will bond directly to laminate fibers and resin as shown in Figure 8. 6) Thoroughly sand girder bond surfaces with 80 grit sandpaper. (IMPORTANT – BOND STRENGTH MAY BE REDUCED IF THIS STEP IS SKIPPED.) 7) Wipe surfaces clean from dust with alcohol or acetone using new paper towels, not shop rags.
  • Page 19   1.6.3 Seakeeper Saddle Preparation 1) Ensure that screws fastening saddles to the installation fixture are tight (Fig 6). 2) Check that each saddle contains 2 plastic screws which will insure an adhesive gap of .080” (2 mm) on top surface of hull as shown in Figure 11.
  • Page 20     1.6.4 Bonding Saddles to Hull Note: If using Plexus MA590 adhesive, the Seakeeper saddles should be installed when PC- 120 is confirmed dry. 1) Assemble Plexus cartridge into either the manual or pneumatic gun as shown. Remove cap on cartridge and attach mixing tip.
