🔍 Key Concepts

• 46 CFR requirements for controllable pitch propeller (CPP) hydraulic systems • Difference between normal operating pressure vs. test pressure • Manufacturer’s maximum allowable operating pressure limitations

💭 Think About

• Ask yourself: When testing pressure systems on a vessel, is it generally safer to go above or stay at/below the manufacturer’s limits? • Think about how 46 CFR usually treats hydraulic and pressure boundaries: do the rules permit exceeding the rated pressure during routine tests, or do they emphasize protecting the system? • Which options sound like general shipyard or management practices, and which sound like a specific regulatory requirement you’d expect to see written in 46 CFR?

✅ Before You Answer

• Check what 46 CFR says about over‑pressurizing hydraulic or pressure systems during tests. • Verify whether 46 CFR ever requires testing at 1.5 times maximum allowable pressure for CPP hydraulics (not boilers or other systems). • Confirm that the correct choice reflects a specific regulatory limit or protection for the hydraulic system, not just general good practice or authority of ship’s officers.

Question 1 of 20

It is necessary to test the hydraulic system of a controllable pitch propeller. According to 46 CFR what should be done?

The vessel must be dry-docked and the propeller removed when performing this test.

The system pressure should be prevented from exceeding the maximum allowable operating pressure set forth by the manufacturer.

The system should be tested at a pressure of 1 1/2 times the maximum allowable pressure.

All necessary repairs must approved by the Chief Engineer of the vessel.
