Hull Plating Side Scans
Marine Corrosion Surveys

Steel boats collect moisture in the hull and if allowed to remain the frames, stringers and plating begin to rust. Some areas inside the hull are hard or impossible to access. Traditionally, inspectors take a number of hand ultrasound readings to measure the thickness of the hull. They can only cover a small fraction of the hull because of the large surface area resulting in uncertain conclusions. Often small-deteriorated areas go undetected. This can result in expensive emergency dry docks later.

We, on the other hand, take an ultrasound readings every ½” of the underwater hull and other assigned areas. We are able to do this precisely and rapidly with an automated robotic scanner. This gives a complete picture of the condition of the hull. The detailed information in our report allows you to make the following informed decisions:

• Make immediate corrective repairs such replacing metal in the hull.
  
• Make immediate preventive actions that will save expensive repairs in the future.
  
• Confidently plan for repairs in areas that are okay now but will need attention later on.

These complete inspections gives assurance to customers, vessel owners, insurance companies and government agencies that all efforts are made to minimize expensive emergency dry-docks, increase reliable operation, and the safety of cargo, personnel and the environment.

BENEFITS OF OUR HULL SURVEY:

• Minimize the dry-dock duration.
• Assurance that all deteriorated areas are found. Alternative inspection techniques such as visual and manual UT measurements only cover a small fraction of the entire hull thus resulting in uncertain conclusions. We take a UT measurement every ½ inch over the assigned areas with the automated scanner and double check questionable areas by hand with a manual UT meter. This eliminates any guess work.
• Reduce cost. We provide a more precise map of corrosion areas by taking a UT reading every ½”. This gives the ability to determine the most cost effective replacement inserts.

So whether you are an owner, military agency, dry dock company, or marine surveyor, considering using our service to increase the quality of dry-dock repairs and reliability of the craft.
