7-A-005: Equipment Carriage Requirements
7-5A1:
Which statement is true regarding a vessel equipped with GMDSS equipment that will remain in Sea Area A1 at all times?
The vessel must be provided with a radio installation capable of initiating the transmission of ship-to-shore Distress alerting from the position from which the ship is normally navigated.
VHF DSC alerting may be the sole means of Distress alerting.
HF or MF DSC may satisfy the equipment requirement.
HF SSB with 2182 kHz automatic alarm generator may satisfy the equipment requirement.
7-5A2:
What statement is true regarding the additional equipment carriage requirement imposed for the survival craft of vessels over 500 gross tons?
A second radar transponder is required.
Additional carriage of two radio equipped lifeboats aft.
Four additional portable VHF radios are required.
The ability to communicate in all modes with any shore station.
7-5A3:
Vessels operating in which sea area(s) are required to carry either Inmarsat or HF equipment or a combination thereof under GMDSS?
A3
All sea areas
A4
A1
7-5A4:
Within a single sea area, what is the primary reason GMDSS imposes carriage requirements for different radio subsystems?
The combined capabilities of redundant subsystems mitigate the risk of a single point of failure.
Redundancy in duplicating all operational functions in the event of a system failure.
Different subsystems are required to meet the specific equipment carriage requirements of national authorities.
GMDSS vessels must be equipped to communicate in all modes with coast radio stations.
7-5A5:
If operating within Ocean Area A1, and outside of NAVTEX coverage, a GMDSS-equipped vessel must carry:
Equipment capable of reception of Maritime Safety Information by the Inmarsat enhanced group call system, or HF SITOR (NBDP).
A GPS receiver
Equipment capable of maintaining a continuous DSC watch on 2187.5 kHz.
An Inmarsat-B terminal.
7-5A6:
What is the equipment carriage requirement for survival craft under GMDSS?
At least three SCT units and two SARTs on every passenger ship and cargo ships of 500 gross tons and upwards.
At least three SCT units and two SARTs on every cargo ship between 300-500 gross tons and the same on all passenger ships regardless of tonnage.
At least two radar transponders must be carried on every cargo ship of 300-500 gross tons and two radar transponders (one for each side) of every passenger ship regardless of tonnage.
All cargo vessels above 300 gross tons and every passenger ship regardless of tonnage must carry three SCT units and two SARTs.
