Blanking and Cofferdam Installation 


The Benefits of Installing Blank's and Cofferdam's 

The ability to create a dry working environment or blank off inlets and overboard discharges safely and quickly underwater is essential if costly delays and dry-docking are to be avoided.

Cofferdam's can take a wide variety of shapes and sizes with many applications including but not limited to:

  • Replacement of hull mounted fittings e.g. sounders, logs, etc.
  • Class approved insert plate hull repairs
  • Repairs or replacement of seals
  • Repairs to structures such as docks and jetties
Cofferdam's can allow work to be conducted from inside the vessel or allow the diver to enter a dry environment created outside the vessel.
