Amendment_0006_-_Specification_Section_Revisions.pdf

C001A.B.4 – AC ELECTRIC MOTOR

The new ladder hoist winch motor shall be suitable for marine application and sized and designed for continuous operation at rated capacity. The motor shall be designed, constructed, and installed in accordance with ABS Rules and shall be ABS approved. The motor shall be provided with grease fittings and shall have positive means for preventing grease from being forced out upon the motor windings.

The motor will be exposed to the weather and therefore shall have IP-56 (watertight or weather tight) protection. The motor shall have class “H” insulation with a class “F” temperature rise rating based on a 50 degree C ambient temperature.

Anti-condensation space heaters shall be provided for the motor. Motor space heaters shall be powered from 120-VAC control power of the drive and shall be energized whenever the motor is secured and de-energized whenever the motor is operating. All space heaters shall be provided with an “ON”-“OFF”-

“AUTO” selector switch and indicating light on the drive.

C001A.B.13.b - FACTORY ACCEPTANCE TESTING

The Contractor shall perform factory acceptance testing (FAT) for the complete winch system (motor, drive, gearbox, and winch) at the manufacturer’s facility. The Contractor shall perform testing to demonstrate the winches rated capacity at rated line speed at the outermost layer of the winch drum, and a brake test to demonstrate the operation of the braking system at rated capacity. The Contractor shall also demonstrate the full safety braking capacity of the dynamic braking feature with power loss to the winch.

The Contracting Officer shall have the option of witnessing the FAT. The Contracting Officer or his

Representative shall be notified at least 10 (ten) working days prior to the scheduled test date.

C001A.C.4 – AC ELECTRIC MOTOR

The motors will be exposed to the weather and therefore shall have IP-56 (watertight or weather tight) protection. The motors shall have class “H” insulation with a class “F” temperature rise rating based on a

50 degree C ambient temperature.

Anti-condensation space heaters shall be provided for both motors. Motor space heaters shall be powered from 120-VAC control power of the motor controller and shall be energized whenever the motor is secured and de-energized whenever the motor is operating. All space heaters shall be provided with an “ON”-

“OFF”-“AUTO” selector switch and indicating light on the drive.

The Contractor shall provide all engineering and materials required to adapt and install the new motors to the existing hauling winches.

The vessel crew will perform all work to install the new motors on to the existing hauling winches.
