Near-Neutral-Buoyancy Composite Pipe
A large-diameter marine intake pipe designed to reduce underwater weight and installation load by combining polyethylene with a high-density composite material.
The Challenge of Large-Scale Deep Sea Water Intake
Large-scale deep sea water utilization requires pipes capable of transporting very large volumes of seawater from deep ocean environments.
As pipe diameter and length increase, underwater weight, towing load, installation stress, and construction complexity become major engineering challenges.
Reducing Effective Underwater Weight
This concept uses a composite pipe structure designed to bring the overall density of the pipe closer to that of seawater.
By reducing effective underwater weight, the pipe may be easier to tow, position, control, and install compared with conventional heavy marine pipelines.
Designed for Large-Scale Intake Infrastructure
The objective is not simply to create a lighter pipe.
The technology is intended as part of a large-scale deep sea water intake system capable of supporting data center cooling, aquaculture, industrial thermal control, and other future applications.
