Technical difficulties associated with the project included the crossing of the various rivers and the construction of pipelines in bog up to 5m deep in areas designated as SACs. An environmental assessment was undertaken to protect areas of conservation along the pipeline corridor and construction techniques were adopted to ensure that any adverse impact on these areas was minimized.
