On a medium-speed motor vessel, what is the typical location of the thrust bearing where propeller thrust is transmitted to the ship's hull?

🔍 Key Concepts

• Axial (thrust) vs. radial (side) loads on the shafting system • Where a dedicated thrust bearing/thrust block is usually installed in a medium‑speed diesel installation • The role of the main reduction gear and line shaft in transmitting power to the hull

💭 Think About

• Think about which component is designed to take up axial thrust and push the ship ahead, rather than just support or guide the shaft. • Ask yourself: on a medium‑speed diesel with reduction gears, which part of the drivetrain is most robustly mounted to the hull to carry large forward and astern thrust loads? • Consider which options describe places that mainly support the shaft radially (keep it centered) versus a place that is purpose‑built to absorb propeller thrust and pass it into the ship’s structure.

✅ Before You Answer

• Verify which option mentions a thrust block or thrust bearing associated with the main power transmission line, not just support bearings. • Check which locations (stern tube, strut, engine, reduction gear/line shaft) are normally used for radial support only rather than for taking up full propeller thrust on larger, medium‑speed installations. • Make sure the chosen option is consistent with a setup that includes a main reduction gear between the medium‑speed engine and the propeller shaft.

Question 1 of 27070

On a medium-speed motor vessel, what is the typical location of the thrust bearing where propeller thrust is transmitted to the ship's hull?

Within the stern tube associated with the tail or propeller shaft as applicable.

Within a strut associated with the propeller shaft.

Within each main engine associated with its crankshaft.

Within the main reduction gear associated with the bull gear shaft or in an independent thrust block associated with the line shaft.
