ATEC provide a wide range of verification, inspection & training services to the Oil & Gas exploration and production, petrochemical, pharmaceutical, renewable and construction markets – With our extensive track record on projects within potentially explosive atmospheres, Atec can add significant value and minimize the burden associated with managing risks associated with hazardous area operation and compliance.
ATEC carried out a certification project for a client who were unaware of their full responsibilities for a component certified product.
The $10 billion LNG asset was built by a US-based EPC to US electrical standard, NEC 500. The plant has hazardous locations of approximately 35% across the asset. LNG assets are operated and maintained by a multifunctional work force. The EPC’s challenge was that they had no personnel trained to maintain the critically hazardous area locations.
The Control System comprised of 2 panels meant for use in an ATEX Zone 2 Area Classification. The first panel had a selection of hazardous area certified components wired to control IO boards and terminals.
The second panel used for fire detection, gas detection, F&G alarm and trip annunciation, along with control for fire suppression and gas prevention. Upon detection of either hazard, the controller was designed to take the appropriate action to mitigate and annunciate the hazard - The panel also included a “Maintenance Bypass” feature which allowed the end user to perform maintenance testing without affecting production. This control system was to be installed in an explosive hazardous area designated for a gas atmosphere. According to the ATEX Directive 2014/34/EU, manufacturers/suppliers (or importers, if the manufacturers are outside the EU) must ensure that their products meet essential health and safety requirements and undergo appropriate conformity procedures.
Although an EC‐type examination certificate is not mandatory for devices of category 3 as specified for use in Zone 2, the manufacturer should issue a declaration of conformity confirming compliance with the ATEX directive and the harmonized standards applicable to these devices. This usually involves testing and assessment by an independent third-party to support this declaration of conformity.
On short notice and up against an aggressive timeline, ATEC traveled to the customer location to perform an on-site evaluation and testing of the equipment
This testing and assessment produced the deliverable of an ExTR (Ex Technical Report), and Technical File Compilation to provide client with the necessary data to demonstrate conformity to the ATEX Directive 2014/34/EU.
