Testing and Checking of GMDSS Batteries Required by SOLAS

รูปภาพ
Testing and Checking of GMDSS Batteries Required by SOLAS GMDSS batteries constitute an important tool which provides power supply for GMDSS equipment operation in case of emergency.  Regulation 13, Chapter 4 of SOLAS sets the following requirements for GMDSS batteries: - batteries must be recharged to the required minimum in less than 10 hours; - the capacity of the batteries must be checked at less than 12 months;  - the batteries should provide power to operate GMDSS for 1 hour if GMDSS is getting the power from emergency generators, and  - for 6 hours if GMDSS is not getting the power from emergency generators.  Surely, to be ready for emergency the batteries should be kept in a proper condition. For this, they should be periodically tested and checked. There are three types of tests: 1. Daily on load/off load test  which ensures that all connections are intact and on loaded batteries do not drop voltage too quickly.  2.  Yearly capacity ...

Load test or capacity test of a GMDSS battery

  Load test or capacity test of a GMDSS battery LOAD TEST OR CAPACITY TEST OF A GMDSS BATTERY (24VDC) Over the years of experience as a radio surveyor, it has been observed that the most common mistake that the ship staff does is the maintenance of the GMDSS battery (reserve source). This emergency source is often misunderstood for compliance. In a nutshell let us have a look into what is this emergency source is all about: As per SOLAS regulations it is mandatory for all vessels built after 1995 to have on board an emergency generator. Older ships might have an emergency generator or a battery bank as emergency source. When we speak of sources of energy it is as below:  Main source of energy - Main Generator. emergency source - This supplies power to emergency lights and other applications on board and  it is  not the one supplying power to GMDSS equipment. The reserve source of energy is normally a 24V DC - lead acid battery which primarily caters to the communicat...
