8、ion for IEEE Std IEEE Std 45-2002 No. Duplicate motor testing requirements as delineated in Clause 13 are not enough for propulsion motor. The propulsion motors are often custom designed due to the power range and propulsion service requirements. The propulsion motor cooling system testing, full loa

9、d testing, overload testing and propulsion duty cycle load testing require extensive preparation. Third party certification is necessary for the propulsion motor manufacture and testing. In general, the motor manufacturer prepares detail motor test procedures for all propulsion motors for customer a

10、nd regulatory body approval. The manufacturer usually follow the approved test procedure which usually witnessed and certified by authorized third party having jurisdiction in this field, such as ABS, Lloyds, DNV, etc. If certain tests are not to be performed due to cost consideration, the certifyin

As an example, the ABS class ship must follow the ABS requirement for manufacture and testing the propulsion motors in accordance with ABS certification requirement. The propulsion motor procurement cost estimate should include manu
