All clothing must meet the requirements shown in the latest NFPA 70E. Such equipment could include a hard hat, face shield, flame-resistant neck protection, ear protectors, flame-retardant material, insulated rubber gloves with leather protectors, and insulated leather footwear. They must wear this equipment if they want to be adequately protected. Electrical workers must be properly trained to safely use and apply appropriate personal protective equipment for the possible electrical hazard they may face.

Arc flash PPE guidance was included in the report and our strategic partner JK Ross were asked to help Xodus Group with their arc flash PPE requirements.NFPA 70E PPE Requirements dictate that an arc flash assessment be performed to determine an arc flash protection boundary accurately. We also provided guidance on the “As Low As Reasonably Practicable” requirements of UK Legislation.ĮSUK presented the Arc Flash Report via video conferencing with the Xodus team from their respective locations.Īrc flash equipment labels were sent to the Xodus site once the design was approved by site personnel. Incident energy hazard reduction analysis was then carried out and preferred options and order of magnitude costs were given for the reduction of the incident energy where it was above 8 cals/cm 2. Up to date, single line diagrams for the electrical network were provided to Xodus Group, that included Site Data, Fault Study and Arc Flash Study Analysis. Incident energy levels and arc flash boundary distances were listed for all equipment included in the scope of the study. Protection device time current characteristic curves showing any instances of miscoordination were provided. We analysed the Offshore Wellhead Platform’s electrical system including:Īny instances where the 3-phase prospective short circuit current exceeded the breaking capacity of protective devices was highlighted in the report. The data collected during the discovery phase of the project was downloaded into our EasyPower® modelling software. *ESUK supply, free of charge, a copy of EasyPower® with every completed Arc Flash Study.ĮSUK and Xodus utilised a secure file exchange server to exchange data, information and files for the project. ESUK’s standard Windows based software tool, EasyPower®* was used to model the electrical systems. ApproachĮSUK agreed the scope and strategy with site management. A project tracker was developed and updated as a live document with the Xodus Group Principal Integrity Consultant on a weekly basis. The project was fixed price and scheduled to take 5 months. We were subsequently asked to deliver arc flash awareness training to staff and contractors and to carry out task-based risk assessments on the high incident energy equipment identified during the study. Online Conference facilities were utilised to train Xodus engineers in methods of Data Collection to collect outstanding data required when attending site. Single Line Diagrams and site data was issued to ESUK through secure means, a gap analysis carried out and data collection documents completed. On this occasion, ESUK were able to work with the client in developing a bespoke data collection process that involved the client’s own engineers and reduce the risk of sending engineers to site. SolutionĮlectrical Safety UK was contracted to undertake the Arc Flash Study for the Offshore Wellhead Platform site, located in the South China Sea, in compliance with UK/European Legislation using the benchmark IEEE 1584 and NFPA 70 Standards.ĮSUK would normally attend a client’s site to gather, quantify and confirm data to complete the Arc Flash Study. Due to the nature of the site and its location, Electrical Safety UK developed a bespoke solution to their requirements to obtain the information required to provide a fixed price proposal for an Arc Flash Study. RequirementsĮSUK received an enquiry from Xodus Group to discuss arc flash and how to manage the risk of an arc flash on an Offshore Wellhead Platform. Xodus provides engineering and advisory services to clients in the oil and gas, LNG, renewables and utility industries worldwide.
