How often must a compulsory vessel's GMDSS...

🔍 Key Concepts

• GMDSS (Global Maritime Distress and Safety System) inspection requirements for compulsory vessels • Which U.S. agency is normally responsible for inspecting radio stations on ships • Difference between annual inspections, monthly tests, and any extra requirements for certain Sea Areas (A1, A2, A3, A4)

💭 Think About

• First, decide which agency is legally responsible for inspecting ship radio stations in the U.S. for GMDSS compliance—FCC or Coast Guard? • Then, think about whether monthly onboard checks by the ship’s own personnel can ever fully replace a formal outside annual inspection. • Consider whether the inspection interval changes when a vessel trades beyond Sea Areas A1 and A2, or whether the requirement stays the same for all GMDSS Sea Areas.

✅ Before You Answer

• Verify which agency the Ship Radio Station License and GMDSS inspections are associated with in U.S. practice (FCC vs. USCG). • Check whether regulations allow waiving the formal annual inspection if the ship’s own GMDSS maintainer does monthly checks. • Confirm if any rule actually specifies a second, six‑month inspection based on operating outside Sea Areas A1 and A2.

The FCC's annual inspection may be waived if, and only if, monthly inspections are performed by the vessel's onboard GMDSS Radio Maintainer.

Annually, by the FCC or designated authority

Annually, by the U.S. Coast Guard

Annually, by the FCC, and every six months if the vessel sails outside of the Sea Areas A1 and A2
