An international energy operator required a Zone 2-compliant high-pressure water supply system to deliver well testing activity. James Fisher supported our customer with a custom-designed booster pump system configured to the rig’s layout. 

Customer challenge

This project required a reliable, high-pressure water supply to feed a water deluge system for heat attenuation during well testing activity. Electrical submersible and booster pumps were to be Zone 2-rated so they could safely function where flammable gases or vapours may be present. 

Solution for our customer 

James Fisher designed, built and tested a bespoke booster pump system configured to the rig’s layout. Specialist technicians also fabricated an A-frame to maximise available space during installation of the submersible pump through the moonpool. 

Our impact to our customer 

• Considerable increase in deluge water delivery and pressure during function testing  
• Safe operations and continuous uptime were prioritised by switching to the secondary pump during high ambient temperatures and increasing inspection frequency  
• Maximised deck space, enabling installation beneath existing rig infrastructure   
• Improved personal  and operational safety utilising Zone 2 classified equipment to meet the regulator and customer’s specifications
