Points on the drawing
1Combat centre and racks
The problem
Electronics racks, consoles and communications equipment are the ship's brain. They must keep working through propulsion vibration, sea slamming and, above all, the shock of a nearby underwater explosion.
What we fit
All-metal mounts and wire rope isolators under each rack: they isolate everyday vibration and absorb shock with enough travel, with no rubber to age.
Typical choice
Vibration mounts S40230–700 kg · 15–20 Hz
Wire rope isolators5–1,000 kg · 7–15 Hz
Electronics and aeronautics vibration mount 70020.7–60 kg · 6–12 HzProven on warships: General Electric (2011), protection of electronics racks on warships.
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
2Mast radar and antennas
The problem
At the top of the mast, the radar and antennas amplify the hull's roll and vibration. A vibrating radar loses accuracy and its connections fatigue.
What we fit
All-metal spring and stainless-steel mesh mounts that withstand the weather and the salt atmosphere.
Typical choice
Vibration mount 1202 / 9141–60 kg · 15–25 Hz
Electronics and aeronautics vibration mount 70010.3–4.5 kg · 6–12 HzWire rope isolators5–1,000 kg · 7–15 HzThe final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
3Propulsion
The problem
The propulsion engines are a warship's main source of noise. Their vibration passes into the hull and out into the water, where an enemy sonar hears it from far away.
What we fit
Suspend the engines on all-metal mounts: the hull stops radiating noise and the ship is harder to detect.
Typical choice
Vibration mounts 954202-95420350–7,000 kg · 11–22 Hz
Vibration mounts 9544121,000–3,000 kg · 15–20 Hz
Vibration mounts 95420150–900 kg · 18–25 HzThe final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
4Generator sets
The problem
The generator sets power the combat systems day and night, including when the ship runs silent. Their vibration reaches the hull just like the engines'.
What we fit
All-metal mounts under each generator set, cutting vibration at the source and resisting the marine environment.
Typical choice
Vibration mounts 95420150–900 kg · 18–25 Hz
Stainless axial vibration mounts70–1,400 kg · 15–25 Hz
Anti-vibration metal cushion0–3,000 kg · 10–35 HzThe final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
5Exhausts and pipework
The problem
Exhausts and pipework connect the engine room with the rest of the ship: if they are rigidly fixed, they carry vibration to the superstructure.
What we fit
All-metal exhaust mounts and telescopic isolators for pipework.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
6Sonar and bow equipment
The problem
The sonar listens to the sea: it needs a quiet ship. Its equipment in the bow also takes slamming and the shock of explosions.
What we fit
Long-travel wire rope isolators and metal cushions that absorb impacts and return the equipment to its position.
Typical choice
Wire rope isolators5–1,000 kg · 7–15 HzAnti-vibration metal cushion0–3,000 kg · 10–35 Hz
Conical shock mount 9350096–12 HzThe final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.

1Avionics bay
The problem
Mission computers, electronic warfare and radios sit in racks next to the cockpit. They take engine vibration at full power, multi-g manoeuvres and hard landings.
What we fit
Light all-metal mounts under each module: they filter vibration, absorb shocks and do not age in the cold and heat of altitude.
Typical choice
Electronics and aeronautics vibration mount 70020.7–60 kg · 6–12 HzSpherical vibration mount for electronics1.9–7 kg · 4–6 HzSilentflex reference: electronics rack mounting for the Eurofighter.
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
2Nose radar

What we fit
Spring and stainless-steel mesh mounts for 1 to 60 kg equipment, working from −70 to +500 °C.
Typical choice
Vibration mount 1202 / 9141–60 kg · 15–25 HzElectronics and aeronautics vibration mount 70010.3–4.5 kg · 6–12 HzThe final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
3Cockpit displays
The problem
The pilot has to read the displays in the middle of combat. A vibrating display is harder to read and its components suffer.
What we fit
50 g spherical aluminium and mesh mounts: small, light and all-metal.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
4Pod and external sensors
The problem
The targeting pod and the sensors under the fuselage need a steady image while the aircraft manoeuvres.
What we fit
Multi-directional wire rope isolators and all-metal mounts that isolate on all three axes and protect against shocks.
Typical choice
Wire rope isolators5–1,000 kg · 7–15 HzElectronics and aeronautics vibration mount 70010.3–4.5 kg · 6–12 HzThe final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
5Engine
Vibration source
The problem
A fighter's afterburning engine is the main source of vibration: it passes it through the whole structure to every unit.
What we fit
Vibration is tackled at each unit, isolating it from the structure close to its mounting point.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
1Main rotor
Vibration source
The problem
Every time a blade passes, the rotor pushes the structure: the helicopter vibrates continuously and at low frequency, in tactical flight and at low level.
What we fit
Since the source cannot be switched off, the equipment is isolated item by item, choosing each mount for its weight and the rotor frequency.
Typical choice
The final choice depends on the load per mount, the speed and the environment. An engineer confirms it with you.
2Mission computers
The problem
Mission computers and displays work against a structure that never stops vibrating.
What we fit
