Ultrahigh-pressure water-jetting systems for offshore ship renovation

The renovation of a large offshore vessel in Hamburg shows how controlled high pressure can make large-scale ship maintenance more efficient. Working with a local partner, DYNAJET supported surface preparation and coating removal on the 236 metre floating production, storage and offloading unit within a tight project schedule.

Before new coatings could be applied, deposits such as mussels, algae and other marine contamination had to be removed from the hull. A 500-bar hot-water unit was used to clean the affected surfaces, while ultrahigh-pressure water jetting at up to 3,000 bar handled paint removal where preparation was required.

Projects like this show the practical value of ultrahigh-pressure water jetting in shipyards and offshore maintenance. When deadlines are tight, professional operators need equipment that supports reliable results, controlled removal work and efficient surface preparation. The focus is not only on cleaning, but on helping the entire refurbishment process move forward without unnecessary delays.

For operators, shipyards and service providers, this case illustrates how high-pressure technology can be applied in a structured way on complex assets. It is particularly relevant where contamination, coating removal and corrosion protection all need to be coordinated on the same vessel. That makes it easier to plan the right cleaning method for the material, the condition of the surface and the next coating step.
