About FN Diving

FN Diving is a class approved underwater ship repair, maintenance and inspection company, headquartered in the Port of Rotterdam with additional bases in Algeciras and Cádiz, Spain. We are the only diving company with a permanent physical presence in the Port of Rotterdam that is fully dedicated to underwater work on seagoing vessels.

Our teams operate 24/7 and are available worldwide on short notice. From our main base in Rotterdam we carry out underwater inspections and repairs in every harbour from Sweden to Brest (France), and far beyond when the job requires it.

What we do

Our expertise covers almost every underwater aspect of a ship, so essential repairs and maintenance can be performed while the vessel remains afloat — avoiding costly drydocking and off-hire time.

  • Underwater Ship Repair — from propeller, thruster and rudder repairs to underwater welding, cutting and class approved hull plating repairs.
  • Underwater Maintenance — hull cleaning, propeller polishing and preventive maintenance that keeps your vessel performing at its best.
  • Underwater Inspection — class approved CCTV in-water surveys, ROV, NDT and bore scope inspections.

Class approved, worldwide

The primary ship classification societies (IACS members) recognize FN Diving for all related in-water surveys. Perfect communication and high standards are essential in the shipping sector, and our people are committed to executing every job as swiftly and cost-effectively as possible — with the highest standards of quality and safety for operators and equipment worldwide.
