Lightweight concrete OTEC cold water pipe tests. Phase II. Special reports.

A 1/3-scale model of a cold water pipe (CWP) for a OTEC plantship was constructed of reinforced lightweight concrete and tested to destruction. Failure occurred at apporximately 138% of the design load for the once-in 100-year-storm condition in the Atlantic-1 siting area. The concept of using Neoprene bearing pads to provide flexibility of the joint between pipe segments was also verified. Measured deflections and stresses generally agreed with computer-generated predictions and validated the design methods used. (ERA citation 06:020039) (A)
