A 4,200 LF section of 42" fiberglass pipeline is used to convey
Kimberly-Clark wastewater from the pulp mill to the Treatment Plant in
New Glasgow, Nova Scotia. This pipeline was installed in 1966 under the
East River and has remained in service without internal structural
evaluation. Our diver and ROV inspections diagnosed six major
leaks that were immediately repaired during a plant shut-down by the
installation of the Miller Weko-Seal system.
J. F. White designed and fabricated an innovative diver travel
system to accelerate inspection and repairs within the pipe. This system
rapidly moved divers, equipment and materials through lengthy
penetrations. The increased speed of repairs allowed the pipeline to be
returned to service ahead of schedule. Two 2,500 foot lightweight
neutrally buoyant dive umbilicals, N2O2 life support systems, double
lock recompression chamber and ROV systems were deployed to
complete this project.
Capability and an established performance record made J.F.
White the contractor of choice, to achieve Owner's goals and bring this
specialized project to completion, on time and within budget.
