• Scope: dry-dock inspection of rudder, pintles, stock, bearings, stern frame
• Key checks: visible parts examined; pintle/neck bearing clearances gauged and recorded; rudder lifted or plates removed if needed; pressure test of hollow rudder; gland/stuffing box repacked; rudder-to-propeller and jumping clearances checked after reinstallation
• Class requirement: IACS UR Z3 §Z3.2.4
• Record: clearances recorded; survey report
• As Second Engineer: supervise checks, verify clearances, ensure records entered, confirm steering gear alignment before undocking
