Rig Cooling 101

Why Rig Cooling:

  • Technology enables oil companies to prove reserves, and improve production clean up, safely.
  • Reduces the heat radiated from well test flaring in accordance with API 521 standards and FlareSim simulations can be conducted pre-job to verify the systems design performance.

 Why not traditional deluge systems for Well Test flaring?

  • Deluge systems are designed to water wet, hot surfaces to cool them down (or in the case of firefighting – suppress the fire)
  • Seawater is used in the deluge system and wetted surfaces can quickly corrode or cause seawater damage to electrical components
  • Significant rig personnel are required on “fire” watch and to man the deluge / fire hose system during well tests
  • One of OPTIMA’s busiest sectors is supplementing or even replacing existing rig deluge systems



  • The patented Targe Nozzles have been performance tested by Lloyds Register for heat attenuation, wind penetration and discharge geometry. In tests conducted by Fire Officers, a hydrocarbon firewall of 1,150° C was attenuated to 7°C at a distance of 2 meters (See Targe spec sheet).
  • The Evo Targe Boom System reduces heat radiation by 70% to 90%. This significantly reduces the heat radiation actually reaching the rig. The Rigside Targe nozzles provide further protection and hot spots can be controlled by the  Containerized Fire System (“CFS”).
  • Proven, patented and Lloyds-certified technology with international experience.

People, Process and Experience: 

  • Trained and competent personnel
  • Extensive HSEQ process and systems in place
  • Global footprint of bases, local content and suppliers
  • OPTIMA understand heat radiation and what it takes to perform safe well test operations.
  • OPTIMA Rig Cooling creates a Hydro Shield minimizing the amount of Seawater on the rig surfaces and the potential of heat radiation greater than API 521 reaching key components of the rig or personnel.
  • OPTIMA only require 1 engineer on days and 1 on nights to manage all heat radiation issues, leaving the rig personnel available for other rig related duties.
