Underwater survey of ships
Company ''ASPTR''Ltd. has many years of experience in underwater ship survey. For example, our specialists have developed a unique method for measuring ship's rudder-propeller unit's gaps. Our divers survey the ship's underwater part with following detailed description of results, including photo and video materials. Upon finding damages or flaws, we carry out works to eliminate them, for example:
• winding of foreign matter on the rudder-propeller unit;
• replacement of anode protection;
• kingstone cleaning, replacement;
• cleaning, grinding and polishing the propeller.
