Sliplining Replacement of Carbon Steel Piping at a Power Generation Facility During Planned Outages

Approximately 2,000 lineal ft of 48-in.- to 72-in.-diameter, unlined carbon steel piping used for cooling water circulation was replaced at Lawrence Energy Center, a 580-megawatt coal-fired power generation facility owned and operated by Westar Energy, during planned outages in spring 2009 and spring 2011. Due to interferences associated with power plant infrastructure above and in close proximity to the piping, sliplining with new carbon steel piping was one of several replacement technologies that were employed. In all, approximately 1,520 lineal ft of sliplining was accomplished during the planned outage timeframes, including a number of elbows and changes in pipe diameter. Sliplining with new carbon steel pipe was found to be a technically sound and cost-effective approach for replacement of existing unlined carbon steel pipe and was especially advantageous given the challenges associated with completing hundreds of lineal ft of pipeline replacement work in somewhat short outage timeframes. With detailed planning, both phases of the construction effort were completed on schedule, safely, and within budget. Keys to the success of the project included the pipeline installation contractor's involvement and ability to innovate early in the project, especially in the conceptual design phase; Westar Energy's implementation of its Outage Readiness Index framework, with partnership in planning between the owner and other project team participants; and extensive collaboration with pipe suppliers prior to fabrication.
