Coltraco Ultrasonics are a British Ultrasonic Technology Manufacturer with 30 years of experience in shipping.

Sinking is the number one cause of loss of ships at sea and fire is the number two. Combatting these areas through inspecting watertight integrity of the holds, doors and MCTs and inspecting the ships’ fixed fire suppression system, Coltraco Ultrasonics can help you to deliver the Safeship®.

Coltraco designed the FLEETSAFE ® a package of innovative safety tools to combat the above and comply with regulations

  1. Contents verification of fixed gaseous fire suppression systems (CO2, NOVEC™ 1230 and FM-200™, etc) via Portalevel® MAX Marine
  2. Convert liquid level to weight or mass of suppressant agent via Portasteele® CALCULATOR
  3. Test watertight integrity of watertight doors, hatch covers and MCT’s via Portascanner® WATERTIGHT
  4. Inspect metal thickness and corrosion  of cylinders + pipework via Portagauge® 3 and Portagauge® 4
