"Ships on Seas"
The electrical equipment aboard ship is inspected and tested during the complete engine survey which occurs every four years.
Such a survey is prescribed under the Rules and Regulations for the Classification of the Ship (depending where your ship is registered)
The electrical survey guidance in this report is based on the periodical survey regulations of Lloyd’s Register of Shipping, London.
Other classification societies have their own rules which although similar to Lloyd’s,shouldbe consulted prior to an electrical survey.
Electrical equipment and services aboard ship must also meet the minimum standards by various national and international organization.
For UMS operation, a survey of the associated alarms, controls and fire detection is required.
For tankers/gas carriers and other ships transporting flammable cargo, an additional survey of all electrical equipment in hazardous areas is carried out during each docking survey and annual survey.
