SIMPLE TO OPERATE AND MAINTAIN

The Coldharbour BWT system uses the gas output from the Coldharbour Sea Guardian™ marine inert gas generator (IGG) linked to specially designed Gas Lift Diffusion (GLD) pipe assemblies mounted inside the ships ballast tanks.

Sea Guardian™ is the first 3rd generation IGG in the world, but any experienced inert gas engineer would quickly feel comfortable operating it.

It generates ultra clean, very low oxygen inert gas. It is compact, stable, reliable and largely maintenance free. During the voyage, the output from the IGG is pumped (by standard type marine compressors) to the GLD units in the ballast tanks where the full treatment takes place.

There are no mechanical filters to block or back flush, no additional seawater control valves, no complex electrical systems and no space consuming equipment to be incorporated into already crowded machinery spaces.
