Sandia’s Materials & Manufacturing Reliability Program has begun testing their novel marine hydrokinetic (MHK) coatings at the Sequim Bay facility, which is a part of Pacific Northwest National Laboratory (PNNL). Tests will reveal anti-biofouling efficacy of coatings developed for MHK technology and of commercial coatings.

Over 150 coupons (1×1, 3×3, and 8×8 inches) will be examined in testing tanks using water from Sequim Bay—to measure attachment of bacteria, algae, barnacles, and other species native to the bay’s environment. PNNL’s George Bonehyo is leading the testing.
