Salt-spray, oil and flame resistant protection for engine rooms, offshore platforms and naval vessels.
A marine engine room is one of the harshest environments any component can be asked to work in. Diesel engines and generators run at extreme temperatures. Fuel lines, hydraulic hoses and lubrication systems carry flammable fluids through confined spaces packed with hot machinery. Salt air accelerates corrosion. Constant vibration wears through unprotected cables and hoses.
At sea, there is no calling for help and waiting. A fire in an engine room — or a hydraulic hose failure that sprays fuel onto an ignition source — can escalate within minutes. The only effective response is prevention.
S Riley Fabrications firesleeve is installed across commercial shipping, offshore platforms, fishing vessels and naval craft. Continuous protection at 260°C, molten splash resistance to 1200°C, outstanding resistance to salt, oil, fuel and hydraulic fluids. Made in Burnley.
Marine engines depend on hydraulic systems for steering, stabilisers, hatch covers and propulsion controls. Hoses routed through hot engine rooms are at constant risk from radiant heat and from flammable fuel sources nearby.
In the event of a fire, an unprotected hydraulic hose can rupture and spray pressurised oil directly onto an ignition source — turning a contained incident into a catastrophic one. Firesleeve over hydraulic hose runs contains failures and provides critical time for crew to respond and isolate systems.
Fuel lines and oil return pipes are the highest-risk components in any engine room. Firesleeve fitted over fuel delivery and return lines provides a barrier between the line and heat sources — reducing the risk of ignition from a pinhole leak or joint failure near hot machinery.
The silicone coating also resists fuel and oil degradation, keeping the sleeve performing over the full service interval without replacement.
Navigation systems, automation controls, lighting, communication equipment and bilge pumps all depend on electrical cabling that passes through or near the engine room. Firesleeve provides 30kV+ dielectric protection and thermal insulation — reducing the risk of electrical fire from short circuits or arcing near hot surfaces.
Offshore oil and gas installations operate under some of the most demanding conditions in industry — high-pressure hydraulics, live hydrocarbon systems, extreme weather and restricted access for maintenance. Firesleeve is specified on platform deck hose runs, wellhead control lines and module wiring where the consequences of fire are severe and evacuation is complex.
Naval vessels demand compliance with strict defence procurement standards. Firesleeve's combination of flame resistance, chemical inertness and mechanical durability makes it suitable for specification on MOD and NATO programmes, where supply documentation and traceability are required alongside performance.
Above-deck cable runs, deck wiring and anchor windlass hydraulics are exposed to constant salt spray, UV radiation and humidity. Unprotected cables degrade rapidly in this environment. Firesleeve's inert silicone surface sheds water, resists UV and remains flexible in low temperatures — protecting deck installations across the full service life of the vessel.
The performance properties that matter in engine rooms, offshore installations and at-sea environments.
For new-build installations, standard Firesleeve slips over hoses and cables before fitting — available from 4mm to 203mm internal diameter. For in-service vessels where lines cannot be disconnected, our Hook & Loop Retrofit sleeve wraps around existing runs without removal, making it practical for shipyard maintenance programmes and at-sea upgrades.
We supply direct to shipyards, marine engineers, offshore contractors and naval procurement teams. Datasheets, compliance documentation and cut-length pricing available on request.
