Built for navies. Held to the naval standard everywhere else.
Almost everything Oldham Seals makes goes to sea with a navy: surface ships and submarines for the UK MOD, its prime contractors and export navies. Commercial marine, offshore and specialty customers get the same construction and the same qualification path, not a lighter one.

Four markets
IMAGE — own or AI-generated surface ship, no claim about the class shown
Naval Surface Ships
Who it is forDesign engineers at prime contractors and shipbuilders, and ship's staff and refit teams
Flexible hose and bellows for the systems that move, shake and have to survive a fire: steering gear and hydraulics, main propulsion and lube oil, diesel generators, cooling, fuel, fire main, ballast and bilge, and replenishment at sea.
In service on every class of Royal Navy surface ship, and sole supplier for new-generation ships

Naval Submarines
Who it is forDesign engineers at prime contractors and shipbuilders, and ship's staff and refit teams
Flexible hose and bellows for the systems a submarine depends on: steering gear and hydraulics, main propulsion and lube oil, HP air, ballast and bilge, weapon handling, and cooling for weapons and sensors.
In service on every class of Royal Navy submarine, and sole supplier for next-generation submarines

IMAGE — generic ro-ro ferry or commercial ship
Commercial Marine
Who it is forTechnical superintendents at ro-ro, ferry and other commercial operators
For engine rooms where fire safety, noise and weight all count. Ro-ro ferries and other commercial ships get the same fire, shock and vibration standard a warship gets. Each assembly is shaped to the pipework, so a refit does not have to redesign the run around a catalogue part.
Lloyd's Register, DNV, ABS and Germanischer Lloyd type approvals already in hand

Offshore & Specialty Applications
Who it is forOffshore and energy engineers, rail traction and fluid power manufacturers, and industrial specialists
Offshore and energy, rail traction, fluid power and industrial work that needs a shape, a pressure or a fluid a catalogue cannot meet. Hose surveys are already standard practice offshore, so Jetrac's survey and register service travels with the product.
Built and tested to your specification in Chichester, and released with certification

Three ways in
Three ways in
Designing it, keeping it in service, or approving the supplier?
Designing a new platform or system?
Bring the application before design freeze. Our engineers confirm feasibility and the standard to qualify to, then shape the assembly to your layout. The approvals are already in hand.
Application Engineering →Send us your drawing →
Keeping hoses in service on board?
Jetrac, our field division, surveys the flexible hoses and bellows on board, other makers' included, records their condition on a register and plans replacement around your upkeep and refit periods.

Approving a supplier?
Type approved by Lloyd's Register, DNV, ABS, Germanischer Lloyd and the MOD, under a BS EN ISO 9001:2015 quality system, with release certification for each assembly.

FAQ
Frequently asked
Where Jetpac® goes, and who we work with.
Which systems on a warship use flexible hose and bellows?Wherever the pipework has to move, absorb shock and vibration or survive a fire: steering gear and hydraulics, main propulsion and lube oil, diesel generators, HP air, cooling, fuel, fire main, ballast and bilge, and replenishment at sea. Submarines add weapon handling and cooling for weapons and sensors.
Do you export outside the UK?Yes. Oldham Seals exports to Australia, Belgium, Canada, Denmark, France, Germany, Greece, India, Italy, the Netherlands, Norway, Spain and the United States, among others. We name countries, never a class, a programme or what was supplied.
Can you tell us which ships use Jetpac®?Jetpac® is in service on every class of Royal Navy ship and submarine, and Oldham Seals is sole supplier for new-generation ships and next-generation submarines. We do not name classes or programmes, and we never publish what we build for a customer.
Do you work with prime contractors and shipbuilders?Yes. We supply the UK MOD and its prime contractors, and work with design teams from the first drawing through qualification. The earlier we see the application, ideally before design freeze, the more freedom there is to shape the assembly to the layout.
Is the commercial product different from the naval one?No. Commercial marine, offshore and specialty customers get the same construction and the same qualification path, with Lloyd's Register, DNV, ABS and Germanischer Lloyd type approvals already in hand.
Do you work outside marine, in rail or industry?Yes, where the job needs a shape, a pressure or a fluid a catalogue cannot meet: rail traction, fluid power and industrial specials, as well as offshore and energy.
Do you supply for refits as well as new builds?Yes. We design and supply for new builds, and make replacements for refits and upkeep periods. Jetrac, our field division, plans those replacements against the dates on the register, so they are ordered in time.
