HMS Prince of Wales has fired up her engines for first time.
The second of the Royal Navy’s new Queen Elizabeth class aircraft carriers has been fitted with four Wärtsilä diesel generators at Rosyth dockyard in Fife.
Each produces a total of 11 Megawatts of power – enough to sustain a town with a population of 25,000 people.
But that is not enough for the Prince of Wales to operate: the Wärtsilä diesel generators account for 40% of the power recquired for the ship to sail; the rest will come from Rolls-Royce MT30 main engines which will drive the ship through the sea.
These have yet to be switched on but when they are, they can generate enough electricity for a town the size of Burnley or Guildford.
“With the first run of HMS Prince of Wales’ diesel generators now complete, the ship is truly coming to life on its own systems,” said Lieutenant James Sheridan-Browne.
“The running of diesel generators will now continue to provide a steady drumbeat to sailing the ship to Portsmouth in 2019.”
“To all involved – and that is a large proportion of the entire workforce – my thanks and congratulations on achieving the first diesel start,” added Simon Lister, managing director of the Aircraft Carrier Alliance.
“This has seen focused effort, great innovation, real perseverance in the face of setbacks, and a commitment to quality that has been truly impressive. These are becoming the hallmarks of HMS Prince of Wales.
"Great teamwork from a large number of groups and individuals. Well done, thank you, and now for the gas turbines!”
