scope:

This guide covers the selection and procedures for electrical cables and cable systems installed in hazardous (classified) locations on oil and gas land drilling rigs.

Purpose

The intent of this guide is to present generally accepted practices for the selection and installation of electrical cables and cable systems in hazardous (classified) locations on oil and gas land drilling rigs. Experience in the oil and gas land rig drilling industry has shown these practices result in safer, more reliable, efficient, and maintainable operations. The practices in this guide should be applied with sound engineering judgment.

This guide will address gaps in the selection, performance, and installation of cables and cable systems for Class I hazardous (classified) locations on oil and gas land drilling rigs not adequately addressed in present standards, recommended practices, and guides. The key drivers are flexibility, portability, allowance for innovation, and expanded use of cables and systems utilized in other industries.
