What are regulations for emergency power supply on ships as per SOLAS ?

Every ship shall be provided with a self contained emergency source of electrical power which shall be so designed and arranged that it will operate at full rated power when the ship is listed 22.5 degrees and when the trim of the ship is 10 degrees from an even keel or any combination of or up to these limits.

 The emergency source of electric power, the associated transforming equipment, any transitional source of emergency power required, the emergency switchboard and the emergency lighting switchboard shall be

  1. located above the uppermost continuous deck.
  2. readily accessible from the open deck.
  3. located at of the collision bulkhead.
  4. so arranged that a fire or other causality in the spaces containing the main source of electrical power, the associated transforming equipment and the main switchboard or in any machinery space of Category A do not interfere with supply, control and distribution of emergency supplies, and 
  5. located where practicable in a space which is not contiguous to the boundaries of a machinery space of Category A or any other space containing the main source of electrical power, the main switchboard or any associated transforming equipment.

Where the emergency source of electrical power is a generator, it shall-

  1. be driven by internal combustion machinery with an independent fuel supply having a flash point of not less than 43.C (Closed Cup Test),
  2. be capable of started automatically on the failure of the main source of electrical power supply unless a transitional source of emergency electrical power is provided in accordance.

If the emergency generator is arranged for automatic starting the generator and the services that would otherwise be supplied from the transitional source of emergency electrical power in compliance with the requirements , shall be automatically connected to the emergency switchboard so that such services will be supplied within 45 seconds of the failure of the main source of electrical power.

The emergency generator may be used to supply services other than emergency supplies in expectional cases for short periods if the independent operation of the emergency source of electrical power is safe-guarded in all circumstances.
