Underwater Propulsion Repairs and Maintenance While Afloat

At 5 Oceans Diving, we specialize in advanced underwater propulsion services designed to keep vessels operational while minimizing downtime and eliminating the need for costly dry dockings. Our experienced divers, propulsion engineers and technicians provide class-approved repair solutions for propellers, thrusters and propulsion systems worldwide.
Operating 24/7 in Rotterdam, Amsterdam, Vlissingen, Antwerp, Ghent, Zeebrugge, Le Havre, Hamburg and Bremerhaven, our teams are also available for rapid mobilization to ports, anchorages and offshore locations around the globe.
Propellers and thrusters are essential for the efficiency, safety and environmental performance of every vessel. Even minor damage can result in increased fuel consumption, vibration, reduced maneuverability and higher emissions. By performing underwater repairs and modifications while the vessel remains afloat, 5 Oceans Diving helps shipowners avoid unnecessary off-hire periods and costly dry-dock repairs.
Working closely with propeller manufacturers, naval architects and classification societies, we ensure that every repair and modification complies with the highest technical and safety standards.
