Question

(a) Explain the purpose of the rudder carrier and pintles. (8)

(b) The speed of a ship is increased to 18% above normal for 7.5 hours, then reduced to 9% below normal for 10 hours. The speed is then reduced for the remainder of the day so that the consumption for the day is the normal amount. Find the percentage difference between the distance travelled in that day and the normal distance travelled per day. (8)

Answer 1

Part (a)

Rudder Carrier:

The rudder carrier is a structure or assembly that supports the weight and movement of the ship's rudder. It serves as a mounting point for the rudder and ensures its stability and proper functioning. The carrier is typically located at the stern of the ship, where the rudder is attached.

Pintle: The pintle is a vertical pin or pivot that connects the rudder to the rudder carrier. It acts as the primary hinge point, allowing the rudder to rotate horizontally for steering purposes. The pintle provides a secure and stable connection between the rudder and the carrier, allowing controlled movement of the rudder.
