Streamline acceptance for assemblies, skids and machinery for oil and gas compliance

For hazardous locations (HazLoc/Ex) skid assemblies, verifying compliance can be challenging if you consider only the individual components. UL Solutions takes a holistic approach and considers the entire assembly and interconnections between parts to help ensure there will be limited regulatory issues or potential red flags from inspectors. These unplanned difficulties can delay getting your product to global markets.

Our expertise in HazLoc requirements and local codes allow us to evaluate, assess, test, certify and advise skids, machinery and other types of assemblies in order to streamline acceptance by the engineering, procurement and construction (EPC), end-user or code authority.

Evaluations for assemblies, skids and machinery in oil and gas compliance

A skid produced by an assembly manufacturer or oil and gas skid manufacturer can be evaluated as a complete, integrated system comprised of individual pieces of equipment.

A modular process skid is a process system contained within a frame that allows the process system to be easily transported. Individual skids can contain complete process systems and multiple process skids can be combined to create larger process systems or entire portable plants. These skid units include equipment skids, oilfield skids, pump skids and tank skids for petroleum, chemical, electrochemical, marine, production, refining, transportation, and oilfield applications, amongst others.

Area classification for assemblies, skids and machinery in oil and gas area

A skid that has its own potential source of release, either under normal or abnormal conditions, needs to be provided with area classification documentation addressing the potential source of release. This classification may be different than the classification of the area in which the skid is intended to be installed.

Equipment assemblies for use in hazardous (classified) locations in the USA can be certified under UL 2011. Additionally, the HazLoc aspects may require additional protection technique standards to be applied. Wiring would need to comply with the applicab
