Arrangement<\/strong>
The Seakeeper<\/span> 18 consists of the Flywheel, Enclosure, Foundation, Electronics, Brake, Cooling, and Cover Subsystems.

Installation Location
<\/strong>The Seakeeper<\/span> is a torque device and does not have to be installed in a specific hull location or on the vessel\u2019s centerline. However, the Seakeeper<\/span> should not be installed forward of amidships to minimize high acceleration loading due to hull-to-wave impacts during operation at high speed or in large waves. Contact Seakeeper<\/span> if a forward installation location is being considered.

Mounting Dimensions
<\/strong>See Drawing No. 90544 \u2013 Seakeeper<\/span> 18 Bolt-In Installation Details<\/a>.
See Drawing No. 90545 \u2013 Seakeeper<\/span> 18 Bond-In Installation Details<\/a>.

Loads<\/strong>
The installer is responsible for designing the foundation to which the Seakeeper<\/span> is attached and for ensuring that this foundation can safely transfer the concentrated Seakeeper<\/span> loads from the frame to the adjacent hull structure.\u00a0 Loads that the Seakeeper<\/span> imposes on the hull structure are explained in Drawing No. 90544 \u2013 Seakeeper<\/span> 18 Bolt-In Installation Details and Drawing No. 90545 \u2013 Seakeeper<\/span> 18 Bond-In Installation Details; these loads do NOT include vessel motion accelerations, such as vertical slam loads which can be significant for higher speed vessels.

Cooling<\/strong>
The Seakeeper<\/span> bearings, Motor Drive Box, and hydraulic manifold are cooled by a closed water \/ glycol mix cooling loop that incorporates a sea water heat exchanger.\u00a0 The installer is responsible for providing 4 – 8 GPM (15.1 \u2013 30.3 LPM) raw water at ambient sea temperature and 30 psi (2.1 bar) maximum pressure to the heat exchanger. Seakeeper<\/span> offers a 24 VDC seawater cooling pump (P\/N 30322).

Electrical<\/strong>
The installer supplies 208-230 VAC, 50\/60 Hz, single phase power on a 30 A service to the Motor Drive Box. The installer is also responsible for supplying 24 VDC @ 10 A service to the Seakeeper<\/span> Control System and 24 VDC at 10 A for the Seawater Pump. A separate 24 VDC breaker is required for the seawater cooling pump power supply. Separate circuit breakers should be used for each Motor Drive Box in multiple Seakeeper<\/span> installations.\u00a0 Similarly, separate circuit breakers should be used for each Seakeeper<\/span> Control System DC Seawater pump in multiple Seakeeper<\/span> installations.

Operator Controls
<\/strong>A compatible MFD or Seakeeper<\/span> 5″ Touch Display is used to start, operate, monitor, and shutdown the Seakeeper<\/span> remotely. The ConnectBox user interface is available on the Seakeeper<\/span> for local operation of the Seakeeper<\/span>.

Performance<\/strong>
Reduction of boat roll is a function of the boat\u2019s displacement, transverse metacentric height (GMT<\/sub>) and hull damping as well as the operating conditions (speed and heading with respect to waves) and sea state.\u00a0 The Seakeeper<\/span> controller regulates the active hydraulic brake to ensure the Seakeeper<\/span>\u2019s anti-roll torque is maximized irrespective of hull characteristics or operating conditions.

Alarm and Monitoring<\/strong>
Sensors, alarms and shutdowns are provided to allow unattended operation.\u00a0 Sensors measure Seakeeper<\/span> and drive temperatures, gimbal angle, brake pressure, and ship motion.\u00a0 The Seakeeper<\/span> controller sends sensor values and alarm information to the display and also locks the brake and shuts down the motor drive in the event of an alarm condition.\u00a0 Seakeeper<\/span> operating history during faults or alarms is recorded in the controller\u2019s memory for subsequent recall if service is needed.\u00a0 Seakeeper<\/span> may access the Seakeeper<\/span>\u2019s software to gather run hours, bearing loading, and hull slamming information.

Safety<\/strong>
The brake automatically locks the Seakeeper<\/span> so it cannot generate excessive anti-rolling torque loads in the event of a system fault or alarm, loss of electrical power or loss of brake pressure.\u00a0 The brake can be locked from the MFD app or 5″ Touch Display, by shutting off AC and DC power at the supply breakers, or locally at the ConnectBox user interface.<\/p>\n","protected":false},"excerpt":{"rendered":"
