By using a method developed at CMU, the biofouling buildup associated with seawater flowing through a simulated OTEC heat exchanger tube was measured by monitoring heat transfer rates with a precision of 1% or better. Two series of experiments were carried out. In the first series seawater was pumped up to two simulated tubes (aluminum 6061-T6) which were mounted in protective housings on board a research vessel moored off Keahole Point. In the second series three simulated tubes (aluminum 6061-T6 and titanium) in their housings were attached to a buoy which was submerged at a depth of 50 feet. Flow velocities of 3 ft/sec and 6 ft/sec were used. In addition, preliminary data on cleaning fouled tubes using M.A.N. brushes were obtained.
