  1. Site visitstoBotas Lightning and Surge Protection

  2. BOTAS • LPG Terminal: Tekridag • Crude Oil Terminal: Ceyhan • Gas compressor station: Sungurlu Lightning and Surge Protection

  3. BOTASWhat have we seen • LPG Termial • No damage caused by lightning during the last years • A few damage in the public housing due to switching surges • Earthing arrangement of the whole site in good conditions • Almost no SPDs in use for protection of power supply and data / IT systems • Some buildings do not have external protection system • Some earthing conductor / connections are painted / corroded • Pipeline insolated flange near to water pump may not be connected to equipotential bonding • Only one down conductor from test clamp to ground at the truck filling station and high earth resistance Lightning and Surge Protection

  4. BOTASWhat have we seen • Crude oil terminal • Damage due to lightning of the telecom tower, Antenna and SPDs are destroyed.SPDs did not fit to application and installation was not correct. • Spark gaps for insulating flanges are missing in upcoming tender documents • Radioactive ESE terminals are still in use • No SPDs for data / IT, except telephone lines • SPDs are in use (SOLA, Mexico) which are not according to IEC (TS) Lightning and Surge Protection

  5. BOTASWhat have we seen • Compressor station • Good lightning protection and earthing system • But no SPDs for power, data, IT • Interference between earthingand cathodic protection • cable length of spark gap for insulating flange is to big Lightning and Surge Protection

  6. BOTASWhat we suggest • LPG Terminal • Use of SPDs, at least Type 2 in public houses • Modify earthing connection / down conductor as mentioned before • Replacement of painted / corroded clamps • Crude oil terminal • Equip Telecom tower with up to date SPDs, installation according to instruction, SPD shall have selectivity to main fuse of the telecom panel. • Replace ESE terminal with latest models Lightning and Surge Protection

  7. BOTASWhat we suggest • Compressor station • Spark Gaps at insulating flanges should be installed direct to the flange with a cable connection as short as possible • Cathodicprotection system-Pipe should be equipped with insulation flange before entering / laving the soil! • In general • SPDs for power / data / IT shall beconsidered as it is required by IEC / TS • Electrical and Electronic Equipment is under threat of damage and hence loss of control of the sites is possible. Lightning and Surge Protection

  8. BOTASWhat we suggest • In gerneral • SPDs for power / data / IT shall be considered in BOTAS specificatins. • Spark Gaps should be considered for insulating flanges for upcoming tenders Lightning and Surge Protection
