Underwater Crew Plays Key Role in Deployment
An important design feature of the WET-NZ is the integral ballast tanks. Prior to deployment, the tanks are filled with air so that when the device is launched it will float on its side, making it easier to tow. Once the WET-NZ is in position at the project site, the tanks will be flooded with water, causing the device to turn upright. To accomplish this, an underwater crew will dive beneath surface to open the WET-NZ ballast valves and allow them to fill with water.
For the WET-NZ deployment, we’ve teamed up with Orca Divers, an Oregon based company with over 20 years of experience in industrial diving and marine construction. The Orca dive team, led by Roger Hermansen, visited the Port of Toledo a few days ago to check out the WET-NZ device and review the installation procedures with the rest of the deployment team.
