Corrosion protection, lightweight construction and insulation are the most demanding challenges in shipbuilding. Here plasma technology opens whole new options to meet those challenges.

Openair® plasma means pretreatment can be performed in atmospheric conditions. This in turn means that entire components on completed ships and tankers can be treated with plasma directly on site. Fully assembled components can be completely pretreated for subsequent coating or for the application of insulation.

Large-area surface pretreatment with Openair® for the insulation of tank interiors

Advantages of Openair® plasma treatment in shipbuilding:

  • Considerable cost savings stemming from improved corrosion protection
  • Uncomplicated application, even for large-area pretreatments
  • Coating pretreatment without use of chemicals (purely physical process)

Large-scale surface treatment

Openair® plasma technology has proven to be the only practical surface treatment for bonding insulating panels in the manufacture of three liquefied natural gas supertankers. An area of 12,000 m² per tanker had to be treated, and achieving 100% seal integrity of the insulation was an absolute necessity.
