National Petroleum News (NPN) has been the independent voice of the petroleum industry since 1909 as the opposition to Rockefeller’s Standard Oil. So, motor fuels marketing and retail is not just a sideline for us, it’s our core competency.

lightning  activity  in  Abu  Dhabi  is  in  fact  low,  the  company  is  now  better  protected  from  a  global  trend:  incrementally  higher  lightning  activity  that  scientists  believe  is  the  result  of  climate  change.  Higher temperatures worldwide are increasing the  warm-weather patterns that lead to severe thunderstorm activity.  Even  without  the  global  increase  in  lightning,  floating roof tanks need adequate protection. Large  storage operations such as Takreer's Ruwais facility, for instance, houses millions of dollars' worth of  product,  which  means  a  single,  lightning-induced  spark can result in a tremendous financial hit. It is  a common and unfortunate challenge that storage  firms  face  worldwide.  In  fact,  some  studies  have  indicated  that  a  majority  of  fires  that  occur  with  petroleum storage tanks are caused by lightning. Part  of  the  difficultly  is  the  fact  that  tanks  are  susceptible not only to direct lightning, but also to  nearby strikes. "When  lightning  is  about  to  strike  nearby,  electrons in the area nearby rush over to the point  of  a  strike,  and  good  grounding  systems  allow  that  to  happen  without  incident,"  explained  Kirk  Chynoweth, systems engineering manager for LEC.  "Unfortunately,  when  the  roof  of  a  floating  roof  tank is not properly grounded, the electrons on the  top  of  the  tank  will  move  at  a  different  rate  than  electrons on the side of a tank, and that difference  in charge balance can create a spark on the edge of  the floating roof." Those sparks occur in just about the worst place  possible, the empty space above a stored petroleum product that is full of flammable fumes. For  that reason, tank fires are often very damaging. A  July 2012 strike that happened at a U.S. company  in Kentucky is not all that unusual: it destroyed  at  least  two  tanks,  set  additional  tanks  on  fire,  and  damaged  on-site  power  lines,  subsequently  creating  power  outages  in  the  surrounding areas.  The  floating  roof  from  one  of  the  tanks  was  blown  off  and  landed  in  the  middle  of  a  nearby highway. Fortunately for Takreer, those types of lightningrelated incidents are less and less likely because of  its  proactive  lightning  protection  operations  with  Consilium  and  LEC.  The  reduced  maintenance  that the RGA requires compared to older lightning  protection systems has led Consilum to begin conversations about lightning protection with some of  Takreer's sister companies in the energy sector. "You  can't  be  too  safe  when  you  have  as  many  assets  to  protect  as  Takreer  does,"  said  Consilium's    www.npnweb.com  n  NPN Magazine Nambiar. "Takreer is a company that goes above and  beyond even the most stringent guidelines for protection and, when it comes to lightning protection, they  have made sure that they have the lowest-impedance  path for grounding with their RGA systems." The  RGA,  a  winner  of  the  E  &  P  Innovation  award, solves the challenges that come with traditional grounding  devices,  providing  comprehensive  lightning  strike  protection for  floating  roof  tanks.  The  product  creates  a  permanent,  reliable,  lowimpedance  bond  that  prevents  fires  triggered  by  lightning  currents.  The  RGA  is  also  a  highly  economical device, and it can be installed on new and  existing tanks in approximately two hours.  The ATEX-certified patented RGA conforms to  both API 545 and NFPA 780 recommendations and  is supported by API 545 as a bypass conductor. LEC is dedicated to providing integrated, industrial  lightning  protection  and  prevention  solutions, products and services by utilizing innovative,  patented  charge  transfer  technology,  grounding  systems  engineering,  surge  protection,  design  and  comprehensive consulting resources. To date, LEC  has installed over 3000 solutions in over 69 countries  and  throughout  the  United  States,  providing  lightning protection to companies in the petrochemical, oil and gas, biochemical, information technology, nuclear energy, utilities and manufacturing  industries.  Lightning Eliminator's Retractable Grounding Assembly RGA® Roy B. Carpenter, Jr., a former chief engineer for NASA's Apollo  Moon Landing Missions and the Space Shuttle design engineering teams, founded LEC in 1971 to study and apply engineering  principles to lightning protection.
