The contract involves the manufacture of watertight doors, including all associated locking/interlocking mechanisms; tunnel door and shielding plug arrangement; tunnel hatch; re-fuelling plugs; and other blanking plugs and inserts.
The watertight doors will be manufactured at CPE’s Workshops in
This contract follows similar contracts for the supply of equipment to Astute-class submarines boat numbers 1 to 4. Equipment for boats 1 to 3 has already been delivered, with equipment for Boat 4 currently progressing through CPE’s workshops.
Vaughan Wilson, project manager at CPE, said: ‘CPE has already carried out numerous contracts for similar work on the Astute-class submarines, including watertight doors, torpedo tubes and re-fuelling plugs.
‘The watertight doors in themselves are very complex items. Some of the items require special materials, heat treatment or need to be fabricated, so it all involves a lot of engineering skills and technical know-how.
‘There’s a lot of complex welding required on the project. We use a range of different welding techniques on the doors, including MIG, TIG and flux-cored arc welding, either manually or automatic.’
