Central States Underwater was established in 1975 due to the oil and gas industries' need for a company that employed commercially trained divers to conduct underwater pipeline inspections and underwater pipeline repairs on the nation's inland waterways.

Ever evolving to meet our customers' needs, CSU has developed into the industry's leader in underwater pipeline inspection and underwater pipeline repair.

From developing underwater pipeline inspection equipment and underwater pipeline repair techniques to utilizing the latest technology available, we at CSU strive to remain on the leading edge of today's underwater industry.
