High Reliability and High Efficiency Electrical Bonding Technology for External Floating Roof Tanks

The Dynamic By-Pass Conductor (DBC) offers a reliable positive bond for External Floating Roof Tanks (EFRTs) for the Oil & Gas and Chemical industries. The DBC delivers efficient electrical bonding between the floating roof and the tank shell, providing a low-impedance channel to significantly reduce explosion risks relating to bound charge and direct lightning strike effects.

Effective protection against lightning

  • The DBC brings significant upgrades to a solution that has been field-tested and proven effective for over 20-years. Product reliability, durability and safety has been significantly upgraded.
  • Conventional bypass conductors may not fully account for conductor slack. The conductor coils randomly on itself, resulting in a high-impedance situation on the tank roof. The DBC avoids this by neatly retracting any conductor slack back into its protective casing, thereby reducing conductor length and maintaining lowest-impedance at all times.
  • The DBC’s design protects EFRTs by ensuring a strong electrical bond which effectively subdues sustained arcs.

Durability and Safety

  • The DBC is designed to maximize product longevity in the highly corrosive hydrogen sulphide (H2S) environment.
  • A solid tape design replaces braided wires for enhanced conductivity and prolonged service life. The Nickel coated solid tape material provides excellent strength and corrosion resistance for longer term reliability.
  • Additional safety feature of rotary damper and braking system ensure the solid tape is always retracted at a measured rate (in the event of tape breakage or disconnected end straps).

Easy to deploy and maintain

  • The main unit of the DBC is enclosed in a highly weather resistant polymer-based casing for easy transportation and deployment.
  • The base unit of the DBC features a modular design that allows for flexible installation options addressing various EFRT mounting requirements.
  • Solid tape is field-replaceable, allowing for on-site maintenance without the cost and delay of shipping the DBC to a service center.
