What is a typical PSC detaining factor?

• A. Minor paperwork inconsistencies
• B. Unclear crew nationality
• C. Major or dangerous deficiencies posing risk to safety, security, or the environment
• D. Noncompliance with port fees

Answer: (C)

Detentions occur when there are major safety, security, or environmental risks on board. The typical detaining factor is finding major or dangerous deficiencies that pose such risks, meaning they directly threaten people, the vessel, or the surrounding environment and cannot be quickly or safely remedied. Minor paperwork problems are deficiencies but don’t usually justify detention; they’re administrative and can often be corrected without delaying the ship’s voyage. Unclear crew nationality or nonpayment of port fees are administrative issues as well and don’t inherently indicate a direct safety or environmental risk, so they aren’t the usual basis for detention. In essence, only substantial, risk-creating deficiencies lead to detaining the vessel.
