GMDSS reserve sources of power
Why reserve power?
In early 2001, an 80 foot crabber with fiver persons on board lost electrical power and steering and was disabled and adrift in the Bering Sea after heavy seas knocked out their pilothouse windows. Radio equipment which could have been used to make an emergency call to the Coast Guard and other nearby fishing vessels was rendered useless by the loss electrical power. The only effective communications the ship had was their 406 MHz EPIRB. During the same month, another fishing vessel, also in the Bering Sea, also lost power and steering, and also had to rely on their EPIRB to communicate with the Coast Guard. That vessel's crew, unable to communicate on any of their radio equipment, were in the pilot house with exposure suits on, with life raft standing by.
The Global Maritime Distress & Safety System took this problem into account, requiring a reserve source of electrical power, to supply radio installations for the purpose of conduction distress and safety radiocommunications, in the event of failure of the ship's main and emergency sources of electrical power. This reserve source of power is capable of simultaneously operating both the VHF radio, and the HF or Inmarsat satellite equipment.
