More Information

The Portascanner® is a 2nd Generation Ultrasonic Watertight Integrity Tester from Coltraco.

The world-leading fully ABS Type Approved & RINA Accepted Portascanner® WATERTIGHT provides a fast and highly accurate method for checking any critical watertight or airtight seal for leak sites, with results in decibel and mathematical linear. Particularly popular with Bulk Carrier operators, this allows all hatch covers to be inspected, ensuring all leaks can be repaired before port departure. This drastically reduces the chance of cargo damage and increases the safety of vessel and crew. Also regularly used on Cable Transits (MCTs), Watertight Doors, Hatch Covers and other similar applications. Removing old fashioned and inaccurate chalk testing, the Portascanner® Technology provides a very quick and accurate method to identify problem areas and fix the issues that exist within these seals.

Watertight Doors on  Naval and Merchant Marine Vessels can be regularly inspected & maintained to ensure the integrity of the Bulk heads and watertight barriers are secure. If these areas are neglected, there can be drastic impacts on flood prevention in the event of a major incident which is exactly what the Portascanner® helps to avoid.

Cable Transit Seals provide a key element in maintaining the integrity of bulk heads and watertight seals onboard Naval, and other Marine assets. As one of the most neglected areas onboard, having the means to quickly identify the exact location and severity of issues in MCTs can dramatically assist  Fleet Operators to enhance the flood, fire & smoke protection that a correctly installed MCT seal provides.

The Portascanner® WATERTIGHT has two main components: the Generator and the Receiver. The Generator produces a powerful ultrasonic signal, which is placed inside and fills any compartment being tested. For extra large holds, an Optional Bulk Generator, Portascanner® SONIC POWER is recommended (as below). The user, with the Receiver unit, then goes to the opposite side of the seal and using the sensor can quickly identify the exact location and severity of any leak site.
