Arrangement<\/strong>
The Seakeeper<\/span> 3 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 to minimize high acceleration loading due to hull\/wave impacts during operation at high speed or in large waves.

Mounting Dimensions
<\/strong>See Drawing No. 90374 \u2013 Seakeeper<\/span> 3 Bolt-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. 90374 \u2013 Seakeeper<\/span> 3 Bolt-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 2 – 6 GPM (7.6 – 22.7 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 12 VDC at 100 A service to the Motor Drive Box, 12 VDC at 15 A service to the Seakeeper<\/span> Control System, and 12 VDC at 15 A service to 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 a 5″ Touch Display is used to start, operate, monitor, and shutdown the Seakeeper<\/span> from the helm. The operator may also use the local ConnectBox interface on the Seakeeper<\/span> 3 to start and shutdown 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. 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, vacuum pressure, 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 Display or by shutting off AC and DC power at the supply breakers.<\/p>\n","protected":false},"excerpt":{"rendered":"
