USCG Exam PracticeCargo gear and rigging
A cargo runner wire on a boom rig has no broken wires visible but has not been renewed in three years. The vessel's biennial proof load test records are current. Under the applicable standards, which statement best describes the correct approach to determining whether the runner should be renewed?
- A. The runner is acceptable for continued service because the biennial proof load test was passed and no broken wires are visible
- B. The runner must be renewed on a calendar basis every two years regardless of condition, per the biennial inspection cycle
- ✓ The runner must be inspected and renewed based on wear criteria, not solely on a calendar schedule, because running wire fatigues quicklyCorrect
- D. The runner is acceptable provided the SWL marking on the boom heel is current and legible
Why C is correct
NAVEDTRA 14343 §9-5 explicitly states that cargo runners and falls are running wire that fatigues quickly and are inspected far more often than standing rigging and renewed on wear criteria, not just on a calendar. Passing the biennial proof load test does not substitute for wear-based renewal criteria for running wire.
