Section 3 Hazardous areas – Drilling, workover and wirelining operations

Parent topic: Chapter 2 Hazardous Areas and Ventilation

3.1 General

3.1.1 This hazardous area classification applies to any part of the drilling derrick or equipment which could potentially release oil or gas from the well, including equipment that is required to operate under controlled emergency conditions, such as during a blow out.

3.1.2 The requirements of Pt 7, Ch 2, 2 Classification of hazardous areas are also to be complied with, where applicable.

3.2 Classification

3.2.1 For units containing drilling facilities, specific reference is to be made to the requirements given in the Chapter 6 - Machinery and Electrical Installations in Hazardous Areas for All Types of Units regarding the extent of hazardous areas on MODUs. However, it must be recognised that other recognised Standards (i.e. EI (formerly IP) Part 15) give additional and potentially different hazardous area guidance associated with drill rigs and facilities. As such, the guidance given in these alternative Standards may be more applicable to the drilling facilities associated with the installation to be classified.
