🔍 Key Concepts

• IMO SOLAS requirements for cargo gear on vessels engaged on international voyages • Distinction between initial proof load test and periodic retest/inspection • Typical inspection and certification cycle for lifting appliances and cargo gear

💭 Think About

• Think about why international rules require an initial proof load test and how often heavy‑duty lifting gear is likely to need a full proof load retest versus more routine visual inspections. • Consider what time interval would balance safety (catching metal fatigue or damage) with practicality (not over‑testing and taking gear out of service too often). • Recall the common certification period you’ve seen stamped or tagged on cargo gear test certificates for ships trading internationally.

✅ Before You Answer

• Verify what SOLAS and related IMO codes state specifically for periodic proof load tests of cargo gear, not just routine inspections. • Check whether there is a difference between annual examinations and full proof load tests, and which the question is asking about. • Confirm the exact interval in years used internationally for cargo‑handling gear test certificates.
