Supporting safe well testing with Zone 2 rig deluge system

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.

This package delivered reliable performance, while our specialist technicians intelligently integrated it into the rig’s systems – delivering a solution to protect safety and productivity.
