Your examiner asks: "What continuous radio watchkeeping is a GMDSS-fitted ship required to maintain while at sea?"

A. A GMDSS ship must maintain a CONTINUOUS DSC WATCH on VHF Channel 70 at all times while at sea. Depending on the ship's sea area of operation, it must additionally maintain continuous DSC watch on the relevant MF distress and safety frequency (2187.5 kHz) and, for ships operating in Sea Areas A3/A4, on HF DSC distress and safety frequencies as well. In addition, the ship must maintain a continuous watch for the receipt of Maritime Safety Information appropriate to its voyage — via NAVTEX where in coverage, and via a satellite MSI service such as SafetyNET/EGC for ocean areas beyond NAVTEX coverage. Modern GMDSS radio installations perform DSC watchkeeping automatically via a dedicated scanner/receiver, without requiring a human operator to continuously listen to the distress channels themselves.

B. GMDSS radio watchkeeping applies only in port; while at sea, no continuous DSC or MSI watch is required under SOLAS Chapter IV.

C. Continuous DSC watch is required only on HF frequencies; VHF Channel 70 watch is optional and left to the master's discretion.

D. MSI watchkeeping (NAVTEX/SafetyNET) is entirely separate from GMDSS and is not a SOLAS Chapter IV requirement at all.

C. The area within the grab's swing radius should be cleared of personnel before the lift

D. Only the crane operator needs to be aware the lift is happening

A. Who must remain clear of the exclusion zone while the lift takes place
