Services > Pipelines and Outfalls

Pipelines, outfalls and associated structures are routinely constructed, maintained and repaired by NUC. Our experience in the construction phases of these structures allows us to provide our customers with valuable planning data, assessments of the condition of their facilities, and cost effective construction, inspection and repair solutions designed to meet their individual needs.

Often times our projects are performed in less than desirable conditions - turbid or black water, severe tidal or river currents, below freezing temperatures, etc. NUC owns the equipment, employs the personnel and has the experience to get the job done in these environments.
