The UK Royal Navy’s Queen Elizabeth Class (QEC) aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales, have received a frequency converter to generate power for the vessels.

The UK Royal Navy’s Queen Elizabeth Class (QEC) aircraft carriers, HMS Queen Elizabeth and HMS Prince of Wales, have received a frequency converter to generate power for the vessels.

Consisting of two parts, the 50t converter and the 50t motor, the frequency convertor will play a key role in providing the carriers with enough electricity wherever they sail.

A new substation, which has been built by the UK Defence Infrastructure Organisation (DIO), will be used to supply the carriers with electricity when homeported at naval base HMNB Portsmouth.

"I am delighted to see the delivery of the frequency converter, a clear sign of the progress we and VolkerStevin are making."

Using about 2.6 miles of cable, the substation has been connected to the National Grid and can supply electricity that is enough to power a small town.

With the help of a hydraulic boom, which 'plugs in' to the side of the aircraft carriers, electricity will be supplied the vessels. The boom is being manufactured in Italy and is slated to be delivered next year.

DIO Project Manager Philip Wise said: “I am delighted to see the delivery of the frequency converter, a clear sign of the progress we and VolkerStevin are making on these facilities.

“The substation is vital for HMS Queen Elizabeth and HMS Prince of Wales so we are pleased to be playing our part in supporting the country’s new aircraft carriers.”

The conversion is considered important since all the ships typically operate on an electrical frequency of 60Hz while the National Grid can cater to 50Hz.

The QEC aircraft carriers are the biggest and most powerful naval assets, which are being built for the Royal Navy in alliance with Babcock, Thales, BAE Systems, and the UK Ministry of Defence.

The vessels will be deployed for a range of operations, including engaging in warfare, as welll as in humanitarian and disaster relief efforts.
