The SeaRazor Twin AST 307/LT is designed to be a fast and efficient underwater cleaning system. It's specifically designed to clean the heaviest marine growth on large VLCC ships to the smallest freighter, floating dry docks, and any underwater structure. Approved for cleaning all soft ablative paints.
Operators that have used similar equipment such as the AST 12 or AST 15 find the AST 307 is easier to operator in open environments.

It's specifically designed to clean the heaviest marine growth on large VLCC ships to the smallest freighter, floating drydocks, and any underwater structure. The SeaRazor Twin reaches forward speeds of 90 feet (27.5 meters) per minute depending on the degree of fouling. The Twin is capable of effectively cleaning 27,900 square feet (8504 square meters) per hour theoretical. The Twin's major advantage over other systems is its use of 4 rebuildable aluminum brushes. This means higher profits because the operator only purchases brush bristle material in bulk. Four rebuildable aluminum brushes are included with the AST-307/LT with brush holder pedestal. The brushes can be reloaded in less than 30 minutes on the job site with appropriate bristle material to meet every changing fouling condition. This means less downtime, less inventory, and higher profits. The unit's brush speed which is diver-controlled ranges from 0 to 300 RPM, minimizes paint damage even on the most sensitive ablative paints. Unlike other models that are dependent upon brush suction to adhere to the hull of the ship, the AST-307/LT uses a HYDRO IMPELLER SHROUD mounted on the backside of the unit facing away from the hull for maximum thrust and diver safety. This allows the unit to adhere to the side of the ship even in tidal flow up to 3 knots. It can move to other areas with the brushes turned off virtually eliminating paint damage. Inferior designs use a propeller mounted in a center hole which enables the unit to adhere to the side of the ship, but pulls all dislodged heavy barnacle and shell through the propeller which can cause propeller failure, hydraulic motor damage, and oil leaks. Even diver safety is a concern with lowered visibility from the debris.
