Chesterfield Special Cylinders

What Chesterfield Special Cylinders does

Chesterfield Special Cylinders is a UK-based designer and manufacturer of high-pressure gas containment solutions, operating as a trading subsidiary of AIM-listed Chesterfield Special Cylinders Holdings plc (LSE: PRES). Founded in 1897 and headquartered in Sheffield, the company manufactures Type 1 seamless steel cylinders (potentially unlimited lifespan), Type 3 aluminium-liner carbon-composite cylinders, and Type 4 full carbon-composite cylinders, with capabilities extending up to 12.2 metres in length. Its products are deployed in submarine ballast systems, breathing air systems, spacecraft gas launch systems, heave motion compensation, hydrogen refuelling and transport, nuclear safety systems, and other safety-critical applications. The company holds an extensive set of regulatory approvals including BS EN ISO 9001/14001/45001, TÜV NORD AD 2000, DNV, Lloyd's, ABS, and Bureau Veritas.

The business operates a B2B enterprise sales model targeting defence primes and navies, hydrogen energy developers, aerospace, offshore, industrial gas, and power generation customers globally, with dedicated regional representatives in Korea, India, and Singapore. Revenue is generated through two streams: one-time product delivery contracts (typically multi-year, with naval programmes commonly delivered over three years) and recurring through-life Integrity Management services, which include on-site and factory-based inspection, non-destructive testing, refurbishment, and recertification to standards such as ISO 11623 and ADR. Pricing is quote-based, dependent on cylinder specification, size, quantity, and application requirements, and the company manufactures to minimum order quantities driven by steel mill production economics.

Customer concentration is anchored on defence, with landmark contracts including the £18.2 million UK naval programme (2023), the Hunter Class Frigate programme for the Royal Australian Navy (manufacturing commenced 2024), a £2.8 million Royal Canadian Navy contract (2024), and a French Navy submarine contract (February 2026). Hydrogen represents a strategic second growth vertical, evidenced by the Shell Netherlands refuelling station supply, Air Products Heathrow trailer refurbishment, and the HYDESS decarbonisation partnership with E.ON. The company employs 101-250 people and has manufactured over 10 million cylinders cumulatively across its 125+ year history.

Revenue model

1. High-pressure gas containment product sales: Design, manufacture, and sale of high-pressure gas cylinders and pressure vessels for safety-critical applications in defence, aerospace, hydrogen, offshore, and industrial sectors. Products include submarine ballast systems, heave motion compensation, dive support, breathing air systems, spacecraft launch systems, and stationary/transportable hydrogen storage. Revenue is generated through one-time product delivery contracts, typically spanning multiple years for large defence programmes.
2. Through-life integrity management services: Inspection, testing, refurbishment, and recertification services delivered both in-situ (on-site at customer locations) and at the Sheffield factory. Includes ADR compliance testing, mobile repair capabilities, and full recertification documentation. Services generate recurring revenue from ongoing regulatory inspection requirements.

Core offering

Chesterfield Special Cylinders designs, manufactures, and sells bespoke high-pressure gas containment cylinders and pressure vessels in Type 1 seamless steel, Type 3 aluminium-liner with carbon composite overwrap, and Type 4 carbon composite with polymer liner constructions. Products are built up to 12.2 metres in length and serve safety-critical applications in defence, hydrogen, aerospace, offshore, industrial, and power generation sectors. The company also delivers through-life integrity management services including in-situ and factory-based inspection, testing, refurbishment, and recertification aligned with BS EN ISO 11623 and ADR standards.

Product overview

Chesterfield Special Cylinders is a world-leading designer and manufacturer of high-pressure gas containment solutions serving safety-critical applications across defence, hydrogen, aerospace, offshore, industrial, and power generation sectors. The product portfolio centres on compressed gas storage cylinders and vessels available in three types: Type 1 seamless steel cylinders (unlimited lifespan), Type 3 cylinders (aluminium liner with carbon composite overwrap), and Type 4 cylinders (carbon composite with polymer liner). These cylinders form the basis for diverse applications including submarine ballast systems, stationary and transportable hydrogen storage, breathing air systems, spacecraft gas launch systems, emergency escape systems, dive support vessel gas storage, heave motion compensation, nuclear safety systems, fuel tank inerting, emergency generator starters, and life raft inflation. The company also offers comprehensive Integrity Management services encompassing both field-based (on-site) and factory-based inspection, testing, refurbishment, and recertification to extend asset life and ensure regulatory compliance.
