NEC: Not Just Electricity in the Oil & Gas Industry

While the term "NEC" often brings to mind the National Electrical Code (US), its significance extends beyond electrical wiring in the oil and gas industry. In this context, NEC refers to a different, yet crucial aspect: "Non-Essential Equipment."

What is Non-Essential Equipment (NEC) in Oil & Gas?

In the oil and gas industry, "Non-Essential Equipment" designates equipment or systems that are not directly involved in the safe and continuous operation of a well, production facility, or pipeline. These systems may be essential for maximizing production or efficiency, but their absence will not immediately compromise safety or disrupt core operations.

Here are some examples of equipment categorized as NEC:

Telemetry systems: While providing valuable data, these systems are not essential for basic well operation.
Process automation systems: These systems help optimize production but do not directly control safety critical functions.
Non-safety-critical instrumentation: Equipment like level gauges or flow meters that are not directly linked to safety shutdown mechanisms.
Lighting and power distribution: Although essential for operations, these are not considered critical for the safety of the facility.

Why is NEC Classification Important?

The classification of equipment as NEC carries significant implications:

Safety: NEC equipment is generally less stringently regulated regarding safety standards and redundancy requirements. This can translate to lower maintenance costs and potentially fewer safety controls.
Risk Mitigation: While NEC equipment is not critical for immediate safety, its failure can disrupt operations and potentially lead to downtime. Careful design and maintenance practices are essential to minimize the risk of equipment failure.
Cost-effectiveness: The less stringent safety requirements for NEC equipment can lead to lower initial investment and operating costs.

Challenges of NEC Equipment:

Defining "Essential" vs. "Non-Essential": The line between essential and non-essential equipment can be blurred, requiring careful consideration of operational requirements and potential consequences of failure.
Potential for Safety Risks: While not directly linked to immediate safety, the failure of NEC equipment can lead to secondary hazards or disruptions that impact safety.
Balancing Cost vs. Safety: The quest for cost-effectiveness can sometimes compromise safety measures, especially when dealing with NEC equipment.

Conclusion:

The term "NEC" in the oil and gas industry refers to "Non-Essential Equipment" and its classification plays a crucial role in managing operational risks and costs. By understanding the implications of this classification, industry professionals can ensure that NEC equipment is appropriately designed, maintained, and monitored to mitigate potential risks while achieving operational efficiency.

Exercise: Identifying NEC Equipment

Scenario:

You are a junior engineer working at an offshore oil platform. Your supervisor asks you to identify and categorize the following equipment based on whether they are considered Essential or Non-Essential:

Emergency Shutdown System (ESD): Automatically shuts down production in case of a safety hazard.
Flow Meter: Measures the rate of oil production.
Emergency Power Generator: Provides backup power in case of a power outage.
Production Control System (PCS): Optimizes oil and gas processing based on real-time data.
CCTV System: Monitors access points and security cameras around the platform.

Instructions:

Identify the NEC equipment from the list above.
Explain your reasoning for classifying each piece of equipment.

Exercice Correction

NEC Equipment:

Flow Meter: While essential for monitoring production, it doesn't directly impact safety in case of failure.
Production Control System (PCS): Optimizes production, but its failure won't directly cause a safety hazard.
CCTV System: Provides security and monitoring, but its failure does not directly impact safety operations.

Explanation:

ESD: This system is crucial for immediate safety and must function correctly to prevent accidents.
Emergency Power Generator: Providing backup power is essential for maintaining critical functions in case of a power outage, directly affecting safety.
CCTV System: Provides security and monitoring, but its failure does not directly impact safety operations.
