1.1 Precautions

• The Seakeeper must only be lifted from the supplied lifting eyes (see Section: Transport and Unpacking).
• The Seakeeper flywheel is supported by precision bearings. While unpacking and lifting the Seakeeper assembly DO NOT drop or impart mechanical shock as damage to bearings could result.
• While handling / installing the Seakeeper assembly, protect exposed hydraulic brake cylinder rods (See Figure 1) from scratches or damage as this could lead to premature seal failure and oil leaks.
• While handling / installing the Seakeeper assembly, do not allow electrical fittings that exit bottom of the Seakeeper enclosure to contact any surface or object as this could damage the fittings and potentially affect the vacuum integrity of the enclosure.
• Exercise care to protect the painted surfaces as damage to finish could lead to early appearance degradation of the installed Seakeeper.

1.1.1 Safety

There is a large torque about the gimbal axis when the Seakeeper is precessing. Seakeeper cover panels are provided to prevent personnel or equipment from contacting the Seakeeper while it is in operation. These covers should not be stepped on or have anything placed on top. The covers should always be in place during operation.

________________________________________________________________________________________

If it is ever necessary to access the Seakeeper while the flywheel is spinning, the Seakeeper must be locked at the display to stop the Seakeeper from precessing.

________________________________________________________________________________________

Stand clear of the Seakeeper and all moving components.

________________________________________________________________________________________

The unit may be started remotely. Assume it could move without warning.

________________________________________________________________________________________

The following must be true before accessing the Seakeeper for maintenance or inspection:
* Input power must be disconnected for at least 10 minutes
* The Seakeeper must be locked
* Flywheel must be at zero speed

• 90845 – Seakeeper 10 Unpacking Instructions

1.2.1 Transport

1. Use a Seakeeper provided shipping crate for transport. P/N 90846. Overall dimensions of a fully packed crate are 43.25 L x 37.5 W x 33.25 H in. (1.1 L x 0.95 W x 0.84 H m) with a weight of 1460 lbs (663 kg).
2. Seakeeper 10 crates can be stacked up to two (2) units high. Only like units should be stacked, i.e., Seakeeper 10 on top of a Seakeeper 10
3. Both Air and Ground transport are acceptable.
4. Seakeeper shipping crates must be transported in environmental conditions between 32°F and 140°F (0°C and 60°C).

1.2.2 Unpacking Crate

1. Reference Seakeeper Drawing No. 90814 – Seakeeper 10 Hardware Scope of Supply for items that ship with the corresponding Seakeeper model.
2. Remove covers, electrical components, display, cables, and misc. items and set aside.
3. Remove packing materials that secure Seakeeper assembly inside the crate.
4. Attach spreader bar (P/N TBD) to the two lifting eyes located on the top of the Seakeeper enclosure. Stay clear of any other parts on the Seakeeper. The Seakeeper 10 weighs 1246 lbs (565 kg). See Figure 2 below.
5. Remove lag bolts from the Seakeeper foundation and prepare to lift the Seakeeper from the crate.

2.1 Mechanical Installation Introduction

The Seakeeper 10 is capable of producing loads up to 5,274 lbs (23.46 kN) at each of the four mounts. These forces should be considered to be acting simultaneously, fully reversing, and will repeat an infinite number of times. Careful consideration should be given to foundation design to ensure it is capable of transferring these loads into the hull. These loads do NOT include vessel motion accelerations, such as vertical slam loads which can be high for higher speed vessels. The responsible party for designing the supporting structure (boat builder, installer, or hired sub-contractor) must accommodate the above forces plus a reasonable factor of safety. Seakeeper recommends a minimum safety factor of 3.0 (yielding a Safety Margin of 2.0).

It is assumed that the installer is familiar with installing mechanical fasteners in marine structures or using high strength adhesives on aluminum and fiberglass (FRP), and has performed structural analysis to assure the structure to which the Seakeeper mounts can properly transfer the loads the Seakeeper creates into the hull structure. If the installer has any doubt about the ability of the structure to transfer the loads to the hull, then a licensed naval architect or marine engineer should be contacted to perform a structural analysis.

The installer should review the following list of reference drawings to ensure the installation procedure is fully understood.

• 90838 – Seakeeper 10 Thru-Bolt Bolt-In Kit
• 90839 – Seakeeper 10 Installation Template

2.2 Selection of Installation Location

The Seakeeper should be installed aft of amidships to minimize high acceleration loadings due to hull/wave impacts during operation at high speed or in large waves. If the only possible Seakeeper location is forward of amidships then the installer should have Seakeeper review the installation location prior to finalizing the design.

Seakeeper can only assess installation location regarding its impact on Seakeeper operation and serviceability.  Seakeeper cannot determine how the installation location will affect the vessel static or directional stability other than cyclic roll reduction. The Installer is responsible for considering the Seakeeper’s effect on the Center of Gravity location, trim, overall stability, and performance of the vessel.

The Installer is solely responsible for ensuring that the Seakeeper is properly located and installed on the vessel foundation with an adequate margin of safety for the specified design loads and vessel operating characteristics.

Selection of mounting location of the Seakeeper should consider the following desirable features:

• Adequate service access for scheduled maintenances and overhaul of the Seakeeper 10 is required. See Figure 4 and Drawing No. 90831 – Seakeeper 10 Bolt-In Installation Details for service clearance requirements.
• The Seakeeper should be installed in a dry space to minimize effects of corrosion.
• The minimum service clearances shown are based on the size of serviceable components and tools required for removal and replacement of these components including field replaceable bearings. The clearances do not consider how the technician will be positioned for access to these areas. Access for a technician must be considered by the installer .
• The clearance and access requirements do not need to be permanent and can be provided via hatches, removable panels, or other temporary means where applicable.
• The installer/designer should consider all these factors for serviceability when defining the installation arrangement.
• Top down access must be incorporated into installation design to allow for adequate regular maintenance, service, and repair.

Figure 3 – Seakeeper 10 Installed Clearance Considerations

2.2.1 Overhead and Service Clearance Considerations

Access above the Seakeeper 10 must be considered for maintenance and service space. Figure 4 shows space considerations around and above Seakeepers installed below deck surface.

2.2.2 Noise/Soundproofing

Seakeeper 10 noise has been measured under steady state conditions (no wave load) in Seakeeper‘s Engineering Lab. The steady state noise is typically <72 dCB at 1 meter. As the frequencies emitting the highest sound pressures are low (like other marine machinery), it is recommended that the Seakeeper be installed in an enclosed space such as a machinery space, lazarette, or bilge. If additional noise reduction is needed, sound proofing insulation can be used in the space around the Seakeeper unit.

2.3.1 Preparation of Vessel Structure

Seakeeper provided mounting hardware is intended to apply to typical installation arrangements. However, each installation, especially custom aftermarket foundations, should be thoroughly reviewed to ensure the provided hardware meets the required thread engagement for the Seakeeper unit being installed. The mounting bolt thread engagement requirements are outlined in the Installation Manuals and Installation Details Drawings for each Seakeeper model. This also applies to Seakeeper model adapter kits and OEM built frames where the bolt hole depth should be checked to ensure the bolts will not bottom, preventing the bolts from achieving the intended preload.

When the Seakeeper provided hardware is not appropriate, the bolt specification (diameter and thread pitch) and grade should be matched in the required length and used with the Seakeeper provided washers. Mounting bolts should always be torqued to the Seakeeper specification. All Seakeeper provided bolts are metric course thread. Hardware specifications are also listed in the Installation Manuals and Installation Details Drawings.

Refer to Seakeeper Drawing No. 90834 – Seakeeper 10 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. 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. Seakeeper recommends a safety factor of 3.0.

Marine-grade aluminum (6061-T6, or equivalent) bar stock is recommended for both blind hole tapping and thru-bolt installations. For blind-hold installations, helical threaded inserts (Helicoils) with a length of 1.5 x bolt-diameter (21 mm) are required to ensure the strength of the tapped holes exceeds that of the mounting bolts (Grade 10.9), which ensures a secure bolted connection between the Seakeeper and hull structure.

The Seakeeper supporting structure should be parallel to the vessel waterline, with up to 2 degrees of allowance for trim. It must be installed in a fore- and aft orientation parallel to the vessel centerline.

In addition, the four areas on top of the structure on which the Seakeeper frame and isolation gaskets will rest need to be co-planar within .06 in. (1.5 mm) to minimize potential distortion of the Seakeeper support frame when installed. The isolation gaskets are only used when the Seakeeper 10 is mounted to a dissimilar metal structure.

Seakeeper provides an installation template kit, P/N 90839, which contains plates matching the mating surfaces of the four feet on the Seakeeper’s frame. 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 forward-aft direction and the port-starboard direction. See Figure 6 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. 90834 – Seakeeper 10 Bolt-In Installation Details, for envelope dimensions. A 3-D model of the Seakeeper is available on the Seakeeper Technical Library (www.seakeeper.com/technical-library/) 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) AS SEEN IN FIGURE 6. REFERENCE SEAKEEPER DRAWING NO. 90834 – SEAKEEPER 10 BOLT-IN INSTALLATION DETAILS.

CAUTION: Tight clearances from cable guide bands to hull structure.
See above figure for dimensions and reference Seakeeper Drawing No. 90834 – Seakeeper 10 Bolt-In Installation Details for complete Seakeeper 10 envelope.

2.3.2 Transfer of Holes to Boat Structure

1. Lower assembled fixture onto hull structure, see Figure 8.
2. The four areas where the feet of the Seakeeper will rest should be coplanar to within .06 in. (1.5mm). See figure below.
3. Align fixture in desired location and transfer holes from fixture plate to the hull structure by transfer punch. Note: Holes in fixture plate are ø 0.55 in. (14 mm).

2.3.3 Bolt-in Installation

Blind-Hole Instructions

1. Remove the Template Fixture and drill TWELVE (12) 0.571 in. ø (14.5 mm ø) holes perpendicular to the vessel structure to a minimum depth of 0.84 in. (21 mm). Take special care to drill perpendicular to the mounting surface.
2. Tap drilled holes for M14-2.0 threaded inserts.
3. Install twelve (12) M14-2.0 x 1.5 D (21 mm length) locking threaded inserts into holes in the hull structure at drilled and tapped locations using the threaded insert manufacturer’s installation tool.
4. Remove the threaded insert prong/tang after the threaded inserts have been installed.

Through-bolt Instructions

Remove the Template Fixture and drill twelve (12) 0.59 IN. (15 mm) ø perpendicular to the vessel structure. Take special care to drill perpendicular to the mounting surface. A drill guide is recommended.

2.3.4 Installation of Seakeeper

1. Lower Seakeeper into position onto the hull foundation beams and align over drilled holes. Apply a small bead of marine sealant (e.g., SILI-THANE 803 or equivalent) between mating surfaces of Seakeeper frame and hull structure to prevent moisture wicking into bolt holes.
   
   1. For dissimilar metal foundations, locate and position the 4 isolation gaskets (P/N 13550) onto foundation beams and apply a small bead of marine sealant (e.g., SILI-THANE 803 or equivalent) between both mating surfaces of each isolation gasket where it contacts the beam and Seakeeper.
2. Install Mounting Bolts, as shown in Figure 10:
   
   1. For Blind-Hole installations (P/N 90837 – Seakeeper 10 Bolt-In Installation Kit), install the Seakeeper supplied Grade 10.9, M14-2.0 x 85 mm fasteners or alternative Grade 10.9, M14-2.0 bolts to maintain a minimum thread engagement of 0.83 in. (21 mm). Apply a moderate coat of nickel-based anti-seize (e.g., SAF-T-EZE nickel-based anti-seize, SBT-4N or equivalent) to the threads of each bolt and include a small bead of marine grade sealant (e.g., SILI-THANE 803 or equivalent) under each bolt head and washer before installation.
   2. For Through-Bolt Installations (P/N 90838 – Seakeeper 10 Through-Bolt Installation Kit), install the Seakeeper supplied Grade 10.9, M14-2.0 x 100 mm fasteners or alternative Grade 10.9, M14-2.0 bolts to maintain a minimum of 2 threads protruding past nut. Apply a moderate coat of nickel-based anti-seize (e.g., SAF-T-EZE nickel-based anti-seize, SBT-4N or equivalent) to the threads of each bolt and include a small bead of marine grade sealant (e.g., SILI-THANE 803 or equivalent) under each bolt head and washer before installation.
3. Torque all fasteners to 135 ft-lbs (183 N-m).
   
   1. New bolts, matching the Seakeeper specification, must be used for each installation and reinstallation that meet the requirements listed above.
4. Proceed to electrical and cooling portion of the installation.

3.4 ConnectBox Connections

Seakeeper 10 Display Options

A compatible display is required with the installation of a Seakeeper 10 to support the full functionality of the unit through the Seakeeper App in addition to the ConnectBox. The Seakeeper App provides an interface for controlling the Seakeeper 10 or viewing the Settings, Service, Info, and Alarm pages. The Seakeeper ConnectBox can be helm-mounted to provide an additional interface for the control of the Seakeeper 10 but does not replace the need for a Seakeeper compatible display.

The Seakeeper 10 has several control interface connection options to support the Seakeeper App:

1. Connect the Seakeeper 10 to a compatible Multifunction Display (MFD) as seen in Figure 26.
2. Install an optional Seakeeper 5″ Touch Display (P/N 90467) as seen in Figure 27.
3. A combination of a compatible MFD and an optional 5″ Touch Display.

The following figures provide schematics of display options. The subsequent sections outline the instructions and references for connecting the Seakeeper 10 to a compatible MFD display or an optional Seakeeper 5″ Touch Display.

30322 – Seakeeper DC Seawater Pump Assembly

TB-90191 – Seawater Cooling Pump Recommendations

The Seakeeper 10 is shipped with the cooling circuit filled and ready for use (See Figure 29). To cool the closed-loop cooling circuit on the unit, it requires a connection to a raw water pump, referred to as the seawater pump. Under all vessel operating conditions, the required seawater flow through the Seakeeper 10 heat exchanger is between 4.5 – 6 GPM (17 – 22.7 LPM). Prior to operation, the glycol level must be confirmed.

Seakeeper offers a compatible self-priming DC Seawater Pump (P/N 30322) that is pre-wired for the Seakeeper 10 installation and covered under the standard Seakeeper Warranty. See Drawing No. 30322, Jabsco Seawater Pump Assembly for details and the Seakeeper Options and Accessories Price List for pricing information.

4.2 Cooling System Considerations

1. The installer is responsible for supplying a dedicated seawater pump and associated plumbing. The Seakeeper heat exchanger’s seawater connections mate with ¾ in. (19 mm) hose. An optional seawater pump, P/N30322, can be purchased through Seakeeper.
2. The seawater pump is powered by the 14 AWG cable, via “SW Pump 24 VDC Out” on the Seakeeper 10, as outlined in Electrical Installation Section.
   
   • This pump must operate on 24 VDC, 10 A power. Pumps requiring other voltages or higher current (20 A maximum) can still be controlled by using this supply to trigger an installer-supplied relay but a separate power source must be provided.
3. To ensure sufficient seawater flow to each Seakeeper unit onboard the vessel, a dedicated through-hull fitting should be installed.
4. It is recommended that the seawater pump is located below the waterline, as close to the vessel’s baseline as practically possible, to maintain positive inlet pressure on the pump in all operating conditions.
5. A self-priming seawater pump is recommended to maintain water flow in all underway conditions. Cavitation can occur at the seawater inlet and potentially cause an air-lock condition restricting seawater flow to the heat exchanger.
6. Vented loops are optional and should only be considered with centrifugal-style pumps. Self-priming or positive displacement-style pumps, including Seakeeper P/N 30322, do not require a vented loop.
7. Maximum seawater pressure in heat exchanger is 20 psi (1.4 bar)
8. The seawater flow requirement through the heat exchanger is 4.5 GPM (17 LPM) minimum and 6 GPM (22.7 LPM) maximum under all boat operating conditions. When sizing the seawater pump, the installer should factor in losses for raw water plumbing. In addition to initial operation at the dock, new Seakeeper installations should be checked to be within the flow requirements while the vessel is at speed. Flows above 6 GPM (22.7 LPM) could affect heat exchanger life.

4.3 Connecting Seawater to Heat Exchanger

Refer to Figure 31 for typical Seakeeper 10 seawater plumbing arrangement.

1. Connect seawater from installer-supplied pump to lower ¾ in. (19 mm) hose barb on heat exchanger. (See Figure 1) Use the same practices as other below waterline seawater plumbing. Required flow rate is 4.5 GPM (17 LPM) minimum and 6 GPM (23 LPM) maximum.
2. Connect seawater discharge (upper hose barb) to overboard drain. (See Figure 29) Use the same practices as other below waterline seawater plumbing.
3. In addition to initial operation at dock, new installations should be checked for minimum 4.5 GPM (17 LPM) flow while vessel is at speed and when backing down. If no other method of confirming flow is available, discharge line may be temporarily diverted to a bucket. Flow is calculated from time to fill a known volume. A self-priming seawater pump (customer/installer supplied) may be required due to installation location to maintain water flow in all underway conditions where cavitation near the intake may occur and potentially cause an air-lock condition restricting seawater flow to the heat exchanger.
4. Inspect raw water plumbing after sea trial for any signs of leakage.
5. Heat exchanger contains removable endcaps to provide access for cleaning the tube bundle.

Seakeeper Optional DC Seawater Pump (P/N 30322)

1. Seakeeper offers a self-priming DC Seawater pump operated at 24 VDC for the Seakeeper 10 (Figure 32).
2. The pump assembly is pre-wired for connection to Seakeeper 10 Seawater Pump Output Cable, “SW Pump Output” and includes a seawater strainer and various fittings. The pump specifications are as follows:

NOTE: Only use Jabsco-provided threaded fittings with DC Seawater Pump 30322.

4.4 Adding Coolant

1. Cooling system is filled to proper level when shipped, with a mixture of 50% ethylene glycol and 50% distilled water. The reservoir and clear tube between heat exchanger and reservoir should be filled with green coolant mixture, as shown in Figure 33. If level has dropped, check for evidence of leaks at all connections before adding fluid as described below. If coolant is at the correct level, skip to Section: Connecting Seawater to Heat Exchanger.
   
   Note: Some amount of entrained air in the fluid is normal and acceptable.  This air will be evident by some cloudiness of the fluid.  As long as the fluid remains at the specified fill level during operation, the remaining cloudiness is not an issue.

2. Mix 50% ethylene glycol with 50% distilled water in a clean container. Refer to Table 1 or glycol manufacturer’s literature for freezing points.

3. Remove vent cap on top of reservoir. Pour mixture in until level reaches 2/3 reservoir as shown in Figure 33. Filling reservoir above this level will not cause any damage but coolant may be expelled from vent on top of cap due to normal thermal expansion of coolant.
4. Connect 24 V to controller.
   
   1. At the MFD app / optional 5″ Touch Display check for any ALARMS
      
      
   2. Press the POWER ON/OFF button.
   3. The flywheel will start to spin and the glycol pump will start.
   4. Recheck glycol level with fluid circulating in coolant circuit. Sight down inside reservoir and check that coolant level is above upper port on reservoir as shown in Figure 4. Replace cap.
   5. After several minutes of running, press POWER ON/OFF button to turn power off to the flywheel.
5. 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. Re-check glycol level after sea trial and add fluid if required.
