Benefits of Hull Cleaning and Propeller Polishing

Marine growth can significantly increase hydrodynamic resistance and reduce overall vessel performance.

Regular underwater maintenance may help to:

  • Improve fuel efficiency
  • Reduce operating costs
  • Maintain service speed
  • Improve charter party performance
  • Reduce greenhouse gas emissions
  • Delay costly dry-docking requirements

Maintaining a clean underwater profile remains one of the most effective ways to optimise vessel efficiency while reducing operating expenses.
