Man with infrared camera and IR windowCase Study: Pacific Drilling Opts for Geo Therm Ltd and CorDEX Infrared Windows

Posted on: 31st, March 2015

This panoramic view of a Nigerian sunset was shot from Pacific Drilling’s drillship Pacific Khamsin with the Pacific Bora drillship in the background. Both vessels opted for the CorDEX IW3000 and IW4000 range of infrared windows that meet with the 11kV transformer rating needs. Geo Therm Ltd (a UK offshore oil and gas inspection and service company) successfully installed more than 240 units per vessel in less than eight days, using a two-man team of offshore service technicians.

GeoTherm & CorDEX Infrared Windows Case Study

The CorDEX range of infrared windows provides a safe, non-invasive means to perform regular visual and periodic thermographic (hotspot) survey inspections and PMs into HV equipment up to 11kV. This is done without fear of electrocution or arc flash. When used in conjunction with the CorDEX Ex-rated range of visual and infrared cameras, all PTW paperwork is further reduced, as is the need to don bulky arc flash PPE suites. Line of sight is now governed by the infrared camera movement and the strategic placement of the infrared window to capture as much as is feasibly practicable of transformer terminations and windings. This is instead of shutting down equipment to open covers or defeat interlocked doors to perform live or residual surveys, both of which have safety and operational limitations.

Designed with safety and quality in mind, the IW range of infrared windows offers clear, unobstructed acuity into energised electrical equipment, while compliant to the NFPA 70E Regulation, as each unit protects personnel by reducing exposure to major electrical hazards. Additionally, their ease of installation, usability and durability have contributed toward CorDEX Instruments Ltd being recognised as one of Europe’s leading Ex-rated equipment manufacturers, winning the Queen’s Award for International Trade in 2014.

In servicing Pacific Drilling’s fleet of high-specification, ultra-deepwater drillships, Geo Therm Ltd’s professional installation service teams retrofit the CorDEX IW range of infrared window orders. This helps towards the performance of the annual offshore electrical thermographic survey inspections on the various rig-wide switchboards and HV transformers.
