Our customer required a method of protecting wildlife and attenuating noise during piledriving operations. James Fisher enabled reliable bubble curtain provision with a high-capacity compressed air system - all from one vessel. 

Customer challenge 

The project required a large, compressed air supply to support bubble curtain noise mitigation during piledriving operations, supporting installation of two offshore substation jackets and dozens of jacket foundations. A single-vessel solution was required to reduce emissions, risk and costs during the project. 

Solution for our customer 

James Fisher designed a single-vessel solution using its stackable ST3100 compressed air delivery package. Supported by computational fluid dynamics modelling and the ST3100's patented cooling matrix, the system maintained reliable performance without heating ambient air. 

Customer impact 

• Reliable performance design high ambient temperatures and restricted ventilation on a PSV with enclosed cargo rails
• Delivered 1,400 m³/min compressed air capacity on a single installation footprint, reducing emissions and vessel requirements 
• Enhanced safety through automated compressor refuelling systems 
• Fully-compliant package meeting DNV and CSC certification 
• Demonstrated technology capability supporting future offshore wind projects in region.
