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.

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.

Award Finalist

The Portascanner® WATERTIGHT was a shortlisted finalist for the 2019 IHS Markit Safety at Sea Safety Product of the Year Awards. 

Bulk Carrier Hatch Cover

The Portascanner® WATERTIGHT is used onboard bulk carriers for inspecting the Watertight or Weathertight hatch cover for leak sites. The magnetic generator can be positioned just inside the hold, on the hatch coaming, removing the need to climb down to position the generator at the bottom of the hold on the tank top.

It is used by the crew for regular maintenance to dramatically reduce the risk of cargo damage from water ingress, and by Marine surveyors for carrying out P&I, Classification Society or Insurance surveys.

CUSTOMER TESTIMONIAL “The fleet was equipped with a unit per Bulk Carrier and the units are and working well, providing the confidence that there will be no problems with water damage claims.” 

Watertight Doors

Watertight Doors on offshore Oil & Gas Rigs, Naval and Marine Vessels are 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.

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.

CUSTOMER TESTIMONIAL “PM testing of WT doors is on a 3 month basis using Portascanner. I also test all WT doors at rig`s Marine Integrity Inspection using the Portascanner and I still consider it invaluable.” “I am doing Watertight Integrity on all Rigs within the Division of India and the Middle east. Great bit of Kit.”

Multiple Cable Transits (MCTs)

Cable Transit Seals provide a key element in maintaining the integrity of bulk heads and watertight seals onboard Naval, Offshore Oil & Gas and 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 Contractors and Fleet Operators to enhance the flood, fire & smoke protection that a correctly installed MCT seal provides.

CUSTOMER TESTIMONIAL: “Our PORTASCANNER WATERTIGHT unit performed well during the entire period of use, proved rugged and we feel sure that if it had not required returning for mandatory calibration and certification, the unit would have performed well for many more years to come.”

New Optional Bulk Generator – Portascanner® SONIC POWER

To inspect watertight and weathertight integrity of hatchcovers for the largest vessel hold sizes.

The Portascanner® SONIC POWER is a ultra powerful generator, with 16+ sensors for widespread reach, >12,000m3 coverage for extra large holds, for placing at the base of cargo holds or on hatch coaming.

Sonic Power

How the Portascanner® SONIC POWER works

Turn on and either place on hold centre or use in-built magnets to attach to hatch coaming. Then begin testing as usual with the Portascanner®.


1. Receiver Rod - The user directs the rod at areas they wish to survey. Any escaping ultrasound is received by the rod and sent to the main unit.

2. Headphones - Any ultrasound that is identified by the unit is given out as audible readings via external headphones.

3. Receiver - The receiver processes and displays any ultrasound signal emitted from a leaking space. The results are visually presented to the user on a screen with decibel readout.

4. Generator - The ultrasonic generator has three transducers. The transducers emit a strong signal  that fills the room/space with pulses of ultrasound.
