What is IEC 60045-26?

IEC 60045-26 is an international standard that specifies the characteristics and performance requirements for shipboard power systems. The standard provides guidelines on the electrical systems installed on ships and their operation under normal conditions as well as during emergency situations. It covers a wide range of topics including electrical safety, power generation, distribution, and protection. This technical article aims to provide a simple and easy-to-understand of the key aspects covered in IEC 60045-26.

Electrical Safety

One of the primary objectives of IEC 60045-26 is to ensure the safety of electrical systems on board ships. The standard sets out requirements for insulation coordination, protection against electric shock, and measures to prevent electric arcs and associated hazards. It also addresses the safe design and installation of electrical equipment, including machinery spaces, control rooms, and other areas where electrical components are present. By complying with these safety requirements, ship operators can reduce the risk of electrical accidents and protect both personnel and the environment.

Power Generation and Distribution

IEC 60045-26 defines the technical principles for generating and distributing electrical power on ships. It covers the selection and sizing of generators, transformers, switchgear, and cables. The standard also provides guidance on load shedding and power quality management to ensure a stable and reliable power supply on board. By following these guidelines, ship operators can optimize the efficiency of their power systems and minimize the risk of power interruptions, which could have serious consequences for the ship's operations.

Emergency Situations

In addition to normal operation, IEC 60045-26 also addresses electrical systems' performance during emergency situations. The standard defines requirements for standby power sources, emergency lighting, and essential services that must remain functional in case of a power failure. It also covers the installation of alarm and monitoring systems to detect abnormal conditions and provide timely warnings to the crew. By adhering to these guidelines, ship operators can ensure the availability of critical electrical services when they are most needed, thereby safeguarding the ship and its occupants.
