This study aims to provide a reference for the pipeline construction
cost, by analysing individual pipeline cost components with historical pipeline
cost data. Cost data of 412 pipelines recorded between 1992 and 2008 in the
Oil and Gas Journal are collected and adjusted to 2008 dollars with the
chemical engineering plant cost index (CEPCI). The distribution and share of
these 412 pipeline cost components are assessed based on pipeline diameter,
pipeline length, pipeline capacity, the year of completion, locations of
pipelines. The share of material and labour cost dominates the pipeline
construction cost, which is about 71% of the total cost. In addition, the learning
curve analysis is conducted to attain learning rate with respect to pipeline
material and labour costs for different groups. Results show that learning rate
and construction cost are varied by pipeline diameters, pipeline lengths,
locations of pipelines and other factors. This study also investigates the
causes of pipeline construction cost differences among different groups.
