year ago Beroa integrated the US company, Beroa
Ramco, Inc. formerly Ramco Solutions, Inc into
the group, an important step for the Group in
the US market. This transaction contributed to
complete Beroa’s strategy of being present
in both capital projects and maintenance works
in refractory installation and chimney construction
in the US, where the company owns 90% of Karrena
International and 35% of International Chimney
During the last year Beroa has
delivered several projects of installation of
refractory material in the US through Karrena’s
activity. The majority of these works involved
international collaboration with other companies
of the Group, taking advantages of the synergy
generated by the different businesses.
The projects include the design
and construction of a reinforced concrete chimney
(600’ in height) with two fiberglass reinforced
plastic liners for Basin Electric Power Cooperative
at the Leland Olds Power plant, in Stanton North
Dakota. Sargent & Lundy selected Karrena for
The Leland Olds Plant was delivered
last July with the collaboration of Bierrum on
the engineering, CRI (Chimneys and Refractories
International) on the supervision and ICC (International
Chimney Corporation) on the workforce.
In March, Karrena International developed its
second project for RRI Energy (formerly Reliant
Energy): the design and construction of a chimney
of 552’-6’’ in height for its
Cheswick Power Plant, in Springdale, Pennsylvania.
Karrena was responsible for
the design of the reinforced concrete column,
the brick liner, pressurized system, as well as
the layout of components including interior ladder,
platforms, liner supports and specialty equipment.
ICC collaborated on the engineering, supervision
and with the workforce.
satisfaction of our clients is our ultimate goal
RRI Energy is an excellent representation.
Two years ago, Karrena Int. developed a reinforced
concrete chimney of 562-62’’ in height
with two brick liners and pressurized system for
its Keystone Power Station, in Shelocta, Pennsylvania.
Another important project worth
mentioning is the design and construction of a
reinforced concrete chimney of 500’ with
two carbon steel liners for Dominion Virginia
Power at Virginia City Hybrid Energy Centre.
Karrena International was responsible
for the complete structural design of the chimney
and the supply of special construction equipment
as well as for the shell erection by their supervisors
and their chimney personnel.
Furthermore, all chimney components
such as the shell, layout of the liner and the
interior fittings were designed by Karrena. This
was the second project delivered to Dominion Virginia
Power. In 2007 a reinforced concrete chimney of
391’ height with a single fiberglass reinforced
plastic (FRP) liner was designed and constructed
for its Chesterfield Power Station at Chester
International Chimney Corporation
(ICC), recently finished the design and construction
of a reinforced concrete chimney (316’ in
height) with two fiberglass reinforced plastic
(FRP) liners for Formosa Plastics Corporation,
CFB Plant in Point Comfort, Texas. ICC was responsible
for the structural design of the reinforced concrete
column, the FRP liners as well as the layout of
components including interior ladder, platforms,
liners supports and specialty equipment.
All these projects and the satisfaction
shown by the customers, as the majority of them
have contracted for more than one contract, are
the best reference and show the growth of the
Beroa Group in the US market.
