  • Page 3 This document is intended to give details and guidance to a boat builder or equipment installer to install the Seakeeper 16/18. The Seakeeper 16/18 can produce vertical loads up to 26.5KN (5,965 lbs.), longitudinal loads up to 15.61KN (3,409 lbs.), and transvers loads of 2.22KN (500 lbs.) at each of the four mounts.
  • Page 4 While handling / installing the Seakeeper assembly, do not allow electrical fittings that exit bottom of the 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 5 Overhead access or sufficient clearance for removal / re-installation of the Seakeeper for overhaul in future years. • The Seakeeper should be installed in a dry space to minimize effects of corrosion. • Clearance for all recommended scheduled maintenance and any repairs is necessary (see...

  • Page 8 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 66-68 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 9 7 of 22 Section 1: MECHANICAL INSTALLATION Selection of Installation Method The Seakeeper 16/18 can be affixed to the hull structure using two methods: 1) Bolt-In installation or 2) Bond-In (Saddle) installation. See figures below. OPTION 1- DIRECT FASTENING OF SEAKEEPER FOUNDATION TO SHIPS STRUCTURE...
  • Page 10 The foundation would fasten directly to hull structure using isolation gaskets and 16x M14X2.0 fasteners. Depending on the structural arrangement to which the Seakeeper is fastened, blind threaded holes or thru-bolting can be utilized. OPTION 2- SADDLE INSTALLATION (4 PLACES)
  • Page 11 4) Remove top and angled face cover panels to access lifting eyes. 5) Attach spreader bar (Seakeeper #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 weighs 1030 kg (2,270 lbs.).
  • Page 12 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 ensure proper strength margins for the loads the Seakeeper will create during operation.

  • Page 16 .13” inches (3 mm) for consistent adhesive bond gap. In addition, the four areas on top of the saddles on which the feet of the Seakeeper foundation will rest need to be co-planar within .06” (1.5 mm) to minimize potential distortion of Seakeeper support frame when installed.
  • Page 17 Seakeeper’s recommended range of 1 to 3mm (.04” to .13”). Note: Do NOT use the installation fixture to establish Seakeeper envelope dimensions. Refer to Drawing No. 90545 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.

Ensure 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 20 7) Re-position installation fixture on girders and double-check that the adhesive gap is within the adhesive manufacturer’s maximum recommended thickness. Seakeeper recommends a maximum gap of 3mm if using Plexus MA590. Note if bonding saddles to a metal structure, contact Seakeeper for hull preparation instructions.
  • Page 21 5) If using Plexus MA590 adhesive, apply one coat of Plexus PC-120 surface conditioner to inside surfaces of Seakeeper foundation saddles in accordance with manufacturer instructions. These instructions are located at the end of this section. If using an alternate adhesive, check with manufacturer if any surface conditioner/etch is required for the aluminum saddles.
  • Page 22 Section 1: MECHANICAL INSTALLATION 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.

  • Page 42 Section 3: COOLING INSTALLATION • Seawater cooling is not required when the Seakeeper is powered off and the flywheel is coasting to a stop The cooling system is self-purging. If small amounts of air are in the system, they will most likely be dislodged during the first sea trial.
  • Page 43 Section 4: STARTUP Introduction This section describes the first startup of the Seakeeper. Also reference Seakeeper Document # 90550, Seakeeper 16 / 18 Operation Manual. • Previous sections for mechanical, electrical and cooling installation must be completed before this startup sequence is initiated.
  • Page 44 11) During normal operation, the Seakeeper should be stopped when stabilization is no longer required. This maximizes long term life as it allows the Seakeeper to start the coast down cycle before cooling is shutoff. Once the vessel is secured in the slip and the crew has shut down the generator and engines, the AC and DC breakers that control the Seakeeper should be switched to the OFF position.
