HMS Vigilant is one of the most important submarines in the MOD’s fleet. So when the time came to renovate it, they needed a company that could get it back in the water as quickly as possible. And that’s what we did. Taking on the £300m contract, we poured over 2.2 million hours of work into overhauling and upgrading the vessel in just 162 weeks. It took 2,000 people to remove its 26,000 parts and complete 200 upgrades – including a major revalidation of all reactor systems and replacement of major equipment, such as the main coolant pumps. And HMS Vigilant was the third submarine of its class to be overhauled at our Devonport, Plymouth site. That’s epic three times over.
