Ensuring the watertight and weathertight integrity of ship hatches is crucial in maintaining marine safety. This blog post explores various testing methods for ship hatches, with a special focus on groundbreaking ultrasonic technology. Coltraco Ultrasonics introduces the Portascanner® WATERTIGHT PLUS, a revolutionary addition to their range, setting a new standard in accuracy and versatility for testing sealed compartments, doors, hatch-covers, and cable transit areas. 

Different Types of Ship Hatch Testing Methods: 
  • Chalk Test: This method involves applying chalk around the hatch perimeter to detect any breaks in the seal when the hatch is closed. 
  • Hose Tests: Water is sprayed around the hatch while it is closed to check for leaks. 
  • Compression Bar and Rubber Packing Inspection: Examination of the compression bars and rubber packing to ensure they are in good condition and provide a proper seal.
