Why might a vessel trading primarily in Paris MoU or Tokyo MoU ports, with a strong record under those regimes, still receive a poor result on its first USCG PSC exam in a US port?

A. USCG PSC applies its own targeting criteria, examination scope, and additional domestic requirements (e.g. MTSA security elements, US-specific MARPOL/ballast water enforcement details) layered on top of the underlying IMO conventions — a strong record under one regime's specific criteria and inspector expectations does not automatically translate to a clean result under a different regime's distinct emphasis and additional domestic layer

B. USCG PSC results are always identical to the vessel's most recent Paris or Tokyo MoU inspection result, since the underlying conventions are the same

C. A vessel's PSC history under other regimes is automatically shared with and binding on USCG inspectors

D. This scenario cannot occur because the USCG only inspects vessels with zero prior PSC history

A. The USCG is a member of all nine regional MoUs simultaneously and applies their combined criteria

B. The MoUs are international agreements between multiple flag/port states sharing inspection data and harmonised deficiency codes; USCG PSC is enforced unilaterally under US domestic law (not a treaty-based MoU), giving the US Coast Guard independent authority to set its own targeting criteria, programmes, and enforcement tools without needing multilateral agreement

C. USCG PSC is legally identical to Tokyo MoU and simply uses a different name for administrative reasons

D. USCG PSC only applies to US-flagged vessels, not foreign vessels calling at US ports

A. The mandatory annual exam makes the targeting matrix redundant, since every vessel is inspected at the same frequency regardless of score

B. Risk-based targeting concentrates inspector effort on higher-risk vessels for more frequent/detailed boarding, but a mandatory minimum annual exam exists as a floor so that even a low-risk-scoring vessel cannot avoid ever being inspected — the two mechanisms work together rather than one replacing the other

C. The targeting matrix determines flag state, not inspection frequency or priority

D. Only Priority I vessels are ever actually boarded; Non-Priority vessels are exempt from inspection entirely
