OES are leaders in EX inspections throughout the globe, performing these inspections and remedial repairs on offshore and onshore drilling rigs.
OES have an extensive track record over the course of three decades.
WHAT IS AN EXSURVEY?
Ex inspections are driven by the International Electrotechnical Commission [IEC] series of standards.
These standards require that electrical apparatus and equipment located in a hazardous area are of an approved design and then inspected prior to use.
An (initial inspection) to ensure it is safe to energize in a hazardous area and that the explosion protection integrity has not been compromised, and also on a regular basis (periodic inspections) to ensure that the equipment has not been damaged, and that its Ex properties have not been compromised by corrosion, decay, wear and tear, etc.
ARE THERE DIFFERENT TYPES OF EX-SURVEYS, AND WHAT ARE THESE?
There are four ‘grades’ of Ex inspection applicable to certified electrical equipment installations: initial, Visual, Close, and detailed; The ‘grade’ of inspection relates to the amount of detail involved in the inspection.
HOW OFTEN SHOULD EX SURVEYS BE COMPLETED?
Many drilling contractors take a periodical approach to their Ex-survey inspection, which as described in this document being a visual, close, or detailed survey spread over a period of not less than 3-5 years.
There is a requirement laid out in IEC that these should be completed every three years. Some other countries may have more stringent requirements such as Australia and New Zealand requires this completed annually.
