Seakeeper M7000 Gyro

The Model 7000 Gyro System consists of the Gyro unit, Motor Drive Box, Gyro Control Box, Cool- ing Loop Components, Keypad, Display, and Cables (AC and DC power cables and CANbus cable not Installation Location The Gyro is a torque device and does not have to be installed in a specific hull location or on the center- line. However, the Gyro should not be installed at forward locations in a high speed boat where the verti- cal accelerations exceed ±1 G. The Gyro Control Box must be mounted on a transverse bulkhead, frame or Mounting Dimensions See dimension diagrams on previous page. The installer is responsible for designing the founda- tion to which the Gyro's saddle beams are attached and for ensuring that this foundation can safely transfer the concentrated Gyro loads from the saddle beams to the adjacent hull structure. Loads that the Gyro imposes on the saddle beams are explained on The Gyro bearings and Motor Drive Box are cooled by a closed glycol cooling loop that incorporates a sea water heat exchanger. The installer is responsible for providing 8 1pm (2.1 gpm) raw water at ambient sea temperature and 6.9 Bar maximum pressure to the heat exchanger. The ambient air temperature in the compartment in which the Gyro Control and Motor Drive Boxes are mounted should not exceed 50° C. The installer is responsible for supplying 185-230 VAC, 50/60 Hz, single phase power on a 30A service to the Motor Drive Box and either 12 VDC @ 20A or 24 VDC @ 10A service to the Gyro Control Box. The DC supply voltage for the Gyro Control Box must be specified at order. Operator Controls A Keypad and small Display are provided to start, operate, monitor, and shutdown the Gyro. Gyro reduction of boat roll is a function of the boat's displacement, transverse metacentric height (GMT) and hull damping as well as the operating conditions (speed and heading with respect to waves) and sea state. The Gyro controller regulates the active hydrau- lic brake to ensure the Gyro's anti-roll torque is maxi- mized irrespective of hull characteristics or operating conditions. In heavy seas, the Gyro rpm may droop when the required power exceeds 2000 watts — this is normal and is designed to limit large power demands at the expense of a small loss of performance Sensors, alarms and shutdowns are provided to allow unattended operation. Sensors measure flywheel bearing temperatures, motor and drive temperatures, vacuum pressure, gimbal angle, brake pressure, and ship motion. The Gyro 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 a fault or alarm condition. Gyro operating history during faults or alarms is recorded in the controller's memory for subsequent recall by a qualified service The brake automatically locks the Gyro so it can- not 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 also be locked from the Keypad or by shutting off power lo- cally at the Motor Drive Box or Gyro Control Box. 14528 South Solomons Island Road Website: www.seakeeper.com © Seakeeper, Inc.

"Rocking the boat" is an expression for upsetting things for good reason. Boat roll is the most disorienting contrast with dry land experience and the least desirable motion on a boat leaving aside sinking. Uncomfortable, tiring, and probably the greatest cause of seasickness it has, until now, been an unavoidable price to pay for the pleasure of being With advent of the Seakeeper Gyro, that is changed forever. Using a device known as a "Control Moment Gyro" and employing the magical principles of gyro- dynamics, it exerts a powerful righting force that virtually eliminates boat roll...
