Abstract :
Battelle has developed a new method for the active trim or list control of undersea vehicles, using small spheres of tungsten alloy, shifted hydraulically between coils of stainless steel tubing at either end of the vehicle. This system is being developed for installation in the DSV-4 Sea Cliff in the fall of 1996, and subsequently in DSV Turtle. It will replace the traditional mercury trim systems (commonly found in many other undersea vehicles as well), which pose potential health risks to the operations staff, and pollution risks to the environment
