CSU undertakes a wide range of land based projects, here is an example: installing replacement steel piles to support pipelines crossing a gully where the original wooden piles were failing.
Removed 300-foot section of pipe & recovered to surface, conducted metrology and completed fabrication on replacement spool piece. Installed 300-foot spool complete with check valve and closing spool. Pressure tested the new assembly successfully and installed articulated concrete mats there after the line was returned to service.
A crack in a line weld on a 22-inch pipe had affected the line's integrity. CSU had to first evacuate an area of marine bottom under the pipe to gain access. The pipe was then cleaned to bare metal and the weld inspected with shearwave ultrasonics which confirmed the defect. Finally the 22-inch pressure repair clamp was installed and the pipeline was re-supported.
