As ever, read the instruction manual....

When they built this:

(HMS Resolution, the UK's first SSBN arriving at Faslane in 1967 for the first time)

The good people involved wrote a book "The Nassau Connection" explaining how they did it - or at least how they managed the project.

(A short book. Sadly out of print.)

It's a short book, at just over 100 pages in a sparse civil service style, and is very interesting. So if you want to build something to replace this:

 

(HMS Vanguard, the first of Trident submarines arrives in 1994)

You'd do well to read this most interesting little book. Equally, if you think this is a silly idea (or even a very silly idea) then there's plenty of food for thought in this book, too. I'll post a fuller review shortly.
