Ships and offshore platforms depend on compressed air for engine starting, control systems, cleaning and service tools. The marine environment adds corrosion, vibration and limited space, so equipment must be specified for the duty rather than borrowed from shore-side practice.
Key applications
- Starting air for main and auxiliary diesel engines at 25–30 bar
- Control and instrumentation air for valves and actuators
- Service air for tools, cleaning and blowing
- Emergency and safety systems
Air quality tiers
Control air must be very dry, typically a -40°C dew point, to prevent freezing and corrosion in instrument lines. Starting air is stored at high pressure in certified receivers, while service air needs general drying and filtration.
Specification notes
Choose corrosion-resistant coolers and coatings for salt-laden air, and vibration-rated components for engine-room mounting. Compact footprints matter in machinery spaces, and classification society rules may apply to pressure vessels and safety valves.
