We were dealing with much smaller vessels than the present air craft carriers. I know I am going back nearly 50 years but does the same policy apply to the carriers & how complex is the route for removal & replacement, how long does the process take? Any answers.

The carriers have been built to last 50 yrs O.S. so no doubt a route has been built in. They will have learnt a bit from the T45s which have to be 'cut open' for R and R.

Leading Voyce in Navy engineering receives Royal honour

ONE of the Royal Navy’s most senior and dedicated engineers has been decorated by The Prince of Wales for commitment to the Service and UK industry.
The Commanding Officer of HMS Sultan in Gosport, Captain John Voyce, has devoted more than 30 years of his life to military engineering – currently ensuring more than 1,000 freshly-trained young technicians and mechanics are delivered to the front-line Royal Navy and Fleet Air Arm every year.
Made an Officer of the Military Division of the Most Excellent Order of the British Empire in the 2020 New Year’s Honours in recognition of his work on the Type 45 programme between 2014 and 2019, he attended an investiture ceremony at Windsor Castle this week.
Captain Voyce was chief engineer and then team leader for the Type 45 programme and, through personal resilience and engineering professionalism, he instilled pride and passion across the Type 45 flotilla. He was known for his ability to inspire and motivate his colleagues, and under his leadership the team achieved a dramatic turnaround in Type 45 availability.

SULTAN

Engineers at HMS Sultan crafted a unique memento to celebrate the 185th birthday of their branch.

Trainee engineers and instructors at the Gosport establishment produced an anniversary tampion – a large ‘plug’ used to prevent the elements seeping into the barrels of warship guns – to demonstrate both their skill… and some of the technological advances across the branch’s lifespan.

‘Set your sights high’ Navy’s senior engineer tells trainees at Sultan

The Navy’s most senior engineer was Guest of Honour at Ceremonial Divisions at HMS Sultan to see the men and women who will drive the Fleet into the mid-21st Century.

The Gosport establishment hosted Ceremonial Divisions for Rear Admiral Jim Higham, Director Ships Support and Chief Naval Engineer Officer, as he underlined the importance of the work Sultan does to provide the Senior Service with highly-skilled air and marine engineers, without whom nothing would fly or sail.

In his first visit since Joining DE&S as Director Ship Support the admiral, who was escorted by Captain Jo Deakin, Sultan’s Commanding Officer throughout, inspected members of the Guard of Honour before presenting several medals. In addressing the Divisions, Admiral Higham said:

“Be proud of what you can offer our Navy and its people… set your sights high….set your sights on the Fleet, a Fleet that engineers and only engineers can sustain”.

Long Service and Good Conduct Medals were presented to Sub Lieutenant S Payne and ET(ME) Lloyd.

HMS Sultan is home to the Defence College of Technical Training’s Defence School of Marine Engineering and the Royal Naval Air Engineering and Survival Equipment School where engineers and technicians are equipped with the skills to function as the ‘beating heart of operational capability’, maintaining, repairing, sustaining and operating our aircraft, ships, submarines and vehicles daily on operations across the globe.

This is a Rolls Royce Spey gas turbine!
kon marine pool them with Royal Navy and we move them in and out of the ship through the inlets… both GT’s enable the ship to reach around 28 knots.
