Expro provides rig cooling systems in conjunction with its flare booms to protect the rig from radiant heat during well tests or early production. The cooling system provides a curtain of water immediately behind the burner heads and in other locations as required by the heat radiation prediction model such as Flaresim. Flaresim generates heat radiation isopleths that can be used to assess the predicted effects of heat on the permanent rig equipment and the safety of operating personnel.

Expro’s systems can be retrofitted to any drilling platform to provide a comprehensive water screen and thanks to having an integrated well test supplier, personnel and associated costs can be minimised.

Expro’s systems comprise:

• Seawater lift pumps, either diesel or electric
• Filtration packages
• Distribution manifolds
• Hoses
• Unique water spray nozzles
• Thermal imaging cameras

Expro’s rig cooling systems can be either interfaced to the existing rig pump and seawater distribution system or based on an independent seawater lift system.

The Vertical Partition sprays are produced by Expro’s ‘fan tail’ high rate nozzles each of which can protect an area of 30m wide by over 10m high at full flow and pressure. Each nozzle uses 10,000 bpd with a feed pressure of 7-10 barg.
