Question 1 of 27070

Q

Dry-docking for a vessel not enrolled in an underwater survey program in lieu of drydocking is due at what interval?

🔍 Key Concepts

• 46 CFR requirements for dry-docking and internal structural exams • Difference between vessels enrolled vs not enrolled in an underwater survey in lieu of drydocking program • The required frequency within a 5‑year inspection cycle for inspected vessels

💭 Think About

• First, focus only on vessels not in an underwater survey program and ignore what you remember about alternate programs. • Ask yourself: within a standard 5‑year inspection period, how many times must a vessel be physically dry‑docked under Coast Guard rules? • Compare the maximum allowed interval between dockings in each option with what would reasonably ensure detection of hull defects over 5 years.

✅ Before You Answer

• Verify in 46 CFR (Subchapters H, I, K, or T depending on vessel type) how many drydock examinations are required per 5‑year period when not in an underwater survey program. • Check whether regulations allow the vessel owner to set the interval freely, or if a maximum time gap between drydockings is specified. • Confirm the exact wording about the maximum interval (in years or months) permitted between the two required drydockings.
