Sheffield-based Chesterfield Special Cylinders (CSC) has been awarded a £2 million contract to supply high pressure gas cylinders for the Royal Navy’s sixth Astute-class nuclear submarine, HMS Agamemnon, currently under construction at Barrow-In-Furness by BAE Systems Submarine Solutions.

The order takes the value of CSC’s contracts for the Astute Class submarines to over £12 million, having already supplied gas and oxygen systems for the first two submarines (Astute and Ambush) which are already in the water and the next three (Artful, Audacious and Anson) being built by BAE Systems in Barrow. A seventh and final Astute, Ajax, is due to enter service in 2024.

The cylinders that CSC is supplying for the Astute submarines are critical to a number of vital operations within the vessels, including breathing gas storage, hydraulic and valve actuation backup, ballast operation and missile launch systems.

Sales manager for CSC, Lee Lawrence, says,  “This contract is testament to the strong, well-established relationship forged over many years between ourselves, BAE Systems and the Royal Navy. It underpins the confidence that BAE Systems and the Royal Navy have in the safety critical products CSC has supplied for the previous five Astute submarines.”

CSC has been supplying the Royal Navy with high pressure gas storage cylinders for ships and submarines since the 1930s. Its reputation for safety-critical systems is second to none and this contract further cements its standing as a leading supplier to BAE Systems.

CSC is a world-leading designer and manufacturer of engineering solutions for global high pressure gas containment markets. As well as serving the global oil and gas sectors, the company has expanded its customer base to other countries’ navies in recent years, including France, India, Brazil and Canada. It offers system design solutions, cylinder manufacture, re-testing and refurbishment services for a range of high pressure, seamless steel gas cylinders for global energy and defence markets. 

Lee Lawrence adds, “Our philosophy is to find the best engineering solution for the customer’s particular requirement, which results in long-standing commercial relationships built on mutual trust and understanding.”

“We have the strongest service team in our industry and serve the more complex requirements of customers who are outsourcing non-core functions.”
