When may a compulsory vessel not be allowed to leave port?

(D). When the vessel has replaced a required piece of GMDSS-related equipment but its performance has not been verified or logged.

47 CFR 80.1105(i)(2) Each GMDSS equipment must be tested and performance verified and the results noted in the ship's record before departure from every port. To accomplish this, each ship shall carry a performance checkoff sheet listing each GMDSS equipment carried on a mandatory basis. GMDSS Equipment Test

80.1107 Test of radiotelephone station. Unless the normal use of the required radiotelephone station demonstrates that the equipment is operating, a test communication on a required or working frequency must be made each day the ship is navigated.

Which statement is FALSE regarding the maintenance of GMDSS equipment at sea?

(A). The GMDSS maintainer may not be the person designated to have primary responsibility for radio-communications during Distress incidents even if licensed as an operator.

OK functions include:

• Ships must carry at least one person who qualifies as a GMDSS maintainer for the maintenance and repair of equipment if the at-sea maintenance option is selected.

• All at-sea maintenance and repairs must be performed by, or under the supervision of a person holding a GMDSS Maintainer license.

• The GMDSS maintainer may be the person responsible for ensuring that the watches are properly maintained and that the proper guard channels and the vessel's position are entered into the DSC equipment.

For more details, please see Code of Federal Regulations, Title 47 Chapter I Subchapter D Part 80 Subpart W Global Maritime Distress and Safety System (GMDSS)
Especially useful is the section § 80.1074 Radio maintenance personnel for at-sea maintenance.

What are the conditions, under GMDSS, whereby a ship is NOT allowed to depart from any port?

(B). The vessel is not capable of performing all required Distress and Safety functions.

This appears to be the only logical choice answer.

47 CFR 80.1105(e) Irrespective of the maintenance methods used, a ship must not depart from any port unless and until the ship is capable of performing all distress and safety functions as specified in § 80.1081. § 80.1105 Maintenance requirements.

What determines the spares and maintenance materials requirements for the SITOR (NBDP) equipment under GMDSS?

(C). The recommendations of the manufacturer.

This appears to be the only logical choice.

47 CFR 80.1105(f) Irrespective of the maintenance methods used, all manufacturers' instruction manuals and maintenance manuals for each piece of equipment required and installed must be available on-board ship.

Adequate tools, spare parts, and test equipment appropriate to the methods used by the ship as recommended by the manufacturer should be provided. The manuals, tools, spare parts, and test equipment, as applicable, should be readily accessible. § 80.1105 Maintenance requirements.

There is info on § 80.1083 Ship radio installations. on § 80.1081 Functional requirements section.
