The presentation introduces ATECO and its Rewinder Earthing System (RES 2000) product. The RES 2000 is a grounding system for floating roof storage tanks that substantially reduces the risk of tank fires caused by lightning strikes or other electrical phenomena. It provides a low-impedance electrical bond between the tank shell and roof that is reliable and unaffected by factors like corrosion or the roof's position. The RES 2000 is cost-effective, easy to install, long-lasting with minimal maintenance needs, and able to retrofit existing tanks effectively.

11. ATECO is a privately held manufacturer and erector of internal floating roofs, geodesic
dome roofs, roof drain systems, emission control systems and perimeter seal systems for
above-ground storage tanks and covers for API separator basins. Operating since 1999,
ATECO is recognized worldwide within the petrochemical industry as the premier leading
supplier of these custom roofs and accessories serving major oil companies and
terminal operators in many countries all over the world.
At ATECO, we deliver exceptional service and deliberately specialize in a several range of
products to serve our customers better. Our engineers design each roof to specific
customer need. ATECO in-house fabricators and certified welders painstakingly make
components to exact specifications and our highly trained ATECO field crews perform
expert field installations.
Our primary objective is to provide superior products and unsurpassed service to the
petrochemical storage industry. We help companies meet or exceed the guidelines and
laws set forth by the EPA, API and NFPA for these types of products and do so with
everyone’s safety and product performance as top priorities.

12. What is the Risk of Rim Fires?
A recent study has shown that at least 31% of all floating roof tank fires are caused by
lightning. Floating roof tanks are uniquely vulnerable when lightning strikes nearby. The shell
typically discharges its electrical charge more rapidly than the floating roof. This difference in
electrical potential, increases the risk of sustained arcing, which can cause a shower of sparks
at the roof shell interface.

13. SHUNTS SOLUTIONS
1. Rust, waxy product deposits, and paint can line the inner wall of
the shell
2. The floating roof can drift slightly off-center and disconnect some
of the shunts from the shell In an attempt to overcome these
shortcomings, facilities have used many other grounding methods.
But all of these methods suffer from similar drawbacks and
typically have unreasonably high impedance, especially during
lightning events.
Substantially reducing the risk of sustained arcs requires a reliable,
full-time, low impedance, and low resistance connection between the
tank shell and roof. Additionally, the connection must operate
regardless of the tank wall's condition.
Inadequate Protection
To combat the risk of rim fires, the industry has been using metal strips called "shunts" that electrically bond
the shell and roof of the tank in multiple locations. Unfortunately, the bond that these shunts establish is
unreliable and creates a greater risk of sustained arcs:

14. The Rewinder Earthing System Solution
The Rewinder Earthing System (RES) is the only solution that is effective in meeting the risk-
reduction requirements:
1. The retractable, braided grounding cable maximizes surface area and adjusts its length with
the height of the floating roof, guaranteeing the lowest possible impedance/resistance.
2. The RES is not affected by the condition of the tank because the RES and cable are bolted
and sealed to optimal locations on the tank shell and floating roof.
3. When properly applied, multiple RESs on each tank provide low-impedance pathways to
safely discharge lightning currents.
To resist corrosion, the reel is constructed from stainless steel and the copper cable is tinned.
The RES is designed to retrofit easily onto any existing tank, even those that are in service. It
is also easy to inspect and is designed to be very low maintenance.

tank with the cable extended to the
roof and bolted into position. Once
installed, the cable extends and
retracts with the roof height.
ATECO's Rewinder Earthing System (RES 2000) is a highly-effective and virtually maintenance-free grounding system
specifically designed for floating roof storage tanks. RES 2000 substantially reduces the risk of tank fires by subduing
sustained arcs during lightning events and other electrical phenomena. The RES 2000 is able to do this better than other
methods, because designers analyzed and found ways to overcome the weaknesses of other, traditional devices for
grounding floating roof tanks.

Rewinder Earthing System, RES 2000, Specifications
The Rewinder Earthing System (RES 2000) is designed to provide the lowest impedance between a External
Floating Roof Tank Shell (wall) and its roof by creating the shortest possible path between the two. This
connection is obtained by keeping constant tension on the wide tinned copper braided cable, which takes
advantage of the “skin effect” at lightning frequencies. The RES 2000 needs minimal maintenance and is easy to
install on both new and existing tanks in petrochemical, water treatment, and other facilities. The RES 2000 can
be installed during erection, maintenance shut downs or during regular operation of a tank. As purchased, the
RES 2000 assembly contains everything required for installation except for an anti-corrosive coating used to
