Arrangement<\/strong>
The Seakeeper<\/span> 26 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 centerline. However, the Seakeeper<\/span> should not<\/strong> be installed forward of the longitudinal center of gravity in a planing vessel.

Mounting Dimensions
<\/strong>See Drawing No. 90271 \u2013 Seakeeper<\/span> 26 Bolt-In Installation Details.
See Drawing No. 90272 \u2013 Seakeeper<\/span> 26 Bond-In Installation Details.

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. Loads that the Seakeeper<\/span> imposes on the hull structure are explained on Drawing No. 90271 \u2013 Seakeeper<\/span> 26 Bolt-In Installation Details and Drawing No. 90272 \u2013 Seakeeper<\/span> 26 Bond-In Installation Details; these loads do NOT include vessel motion accelerations, such as vertical slam loads which can be high 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 seawater heat exchanger. The installer is responsible for providing 4 \u2013 8 GPM (15.1 \u2013 30.3 LPM) raw water at ambient sea temperature and a maximum pressure of 20 psi (1.4 bar) to the heat exchanger.

Electrical<\/strong>
The installer is responsible for supplying 208-230 VAC, 50\/60 Hz, single phase power on a 20 A service to the Motor Drive Box. Additionally, the installer is responsible for supplying 24 VDC at 10 A service to the Seakeeper<\/span> Control System and 24 VDC at 10 A for the seawater pump. Separate circuit breakers should be used for each Motor Drive Box in multiple Seakeeper<\/span> installations. Similarly, separate circuit breakers should be used for each Seakeeper<\/span> Control System and 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. Locally, one may operate the Seakeeper<\/span> with the ConnectBox user interface.

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. The Seakeeper<\/span> controller regulates the active hydraulic brake to ensure the Seakeeper<\/span>\u2019s anti-roll torque is maximized regardless of hull characteristics or operating conditions.

Alarm and Monitoring<\/strong>
Sensors, alarms and shutdowns are provided to allow unattended operation. Sensors measure Seakeeper<\/span> and drive temperatures, gimbal angle, brake pressure, and ship motion. 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. Seakeeper<\/span> operating history during faults or alarms is recorded in the controller\u2019s memory for subsequent recall if service is needed. 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. The brake can be locked from the MFD \/ 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":"
